| Summary of Significant Accounting Policies |
2. Summary of Significant Accounting Policies Basis of Presentation The accompanying interim condensed consolidated financial statements (the “Unaudited Condensed Consolidated Financial Statements”) are unaudited. These Unaudited Condensed Consolidated Financial Statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto for the year ended December 31, 2018 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, filed with the Securities and Exchange Commission (“SEC”) on February 28, 2019 (the “2018 Annual Report”). The Unaudited Condensed Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the SEC. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. The Unaudited Condensed Consolidated Financial Statements reflect all adjustments, consisting of only normal recurring adjustments, necessary for the fair presentation of the Company’s financial position as of March 31, 2019 and December 31, 2018, results of operations, comprehensive income, changes in shareholders’ equity and cash flows for the three months ended March 31, 2019 and 2018. These interim period results are not necessarily indicative of the results to be expected for any other interim period or the full year. In the results of operations for the three months ended March 31, 2019 and 2018, the Company has separately presented interest income from other income, net due to the increase in amount during the three months ended March 31, 2019 as compared to the three months ended March 31, 2018. Additionally, the results of operations and statement of cash flows for the three months ended March 31, 2018, were adjusted due to the impact of the adoption of Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“Topic 606”). The accompanying Unaudited Condensed Consolidated Financial Statements reflect the application of certain significant accounting policies as described below and elsewhere in these notes to the Unaudited Condensed Consolidated Financial Statements. As of March 31, 2019, there have been no material changes in the Company's significant accounting policies from those that were disclosed in the 2018 Annual Report, other than those resulting from the adoption of ASC 842, which is described below. Principles of Consolidation The accompanying Unaudited Condensed Consolidated Financial Statements include the accounts of CarGurus, Inc. and its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The Company prepares its Unaudited Condensed Consolidated Financial Statements and related disclosures in conformity with GAAP. Subsequent Event Considerations The Company considers events or transactions that occur after the balance sheet date but prior to the issuance of the financial statements to provide additional evidence for certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated as required. The Company has evaluated all subsequent events and determined that there are no material recognized or unrecognized subsequent events requiring disclosure. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Significant estimates relied upon in preparing these Unaudited Condensed Consolidated Financial Statements include revenue recognition and revenue reserve, the valuation of goodwill and intangible assets, the capitalization of product, technology, and development costs for website development and internal‑use software, and the recoverability of the Company’s net deferred tax assets and related valuation allowance. Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances. Actual results may differ from management’s estimates if these results differ from historical experience, or other assumptions do not turn out to be substantially accurate, even if such assumptions are reasonable when made. Concentration of Credit Risk The Company has no significant off‑balance sheet risk, such as foreign exchange contracts, option contracts, or other foreign hedging arrangements. Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash, cash equivalents, investments, and trade accounts receivable. The Company maintains its cash, cash equivalents, and investments principally with accredited financial institutions of high credit standing. Although the Company deposits its cash and investments with multiple financial institutions, its deposits, at times, may exceed federally insured limits. Credit risk with respect to accounts receivable is dispersed due to the large number of customers. The Company routinely assesses the creditworthiness of its customers. The Company generally has not experienced any material losses related to receivables from individual customers, or groups of customers. The Company does not require collateral. Due to these factors, no additional credit risk beyond amounts provided for collection losses is believed by management to be probable in the Company’s accounts receivable. For the three months ended March 31, 2019 and the year ended December 31, 2018, no individual customer accounted for more than 10% of total revenue. As of March 31, 2019, one customer accounted for 13% of net accounts receivable. As of December 31, 2018, two customers accounted for 21% and 14% of net accounts receivable, respectively. No other individual customer accounted for more than 10% of net accounts receivable at March 31, 2019 or December 31, 2018. Included in net accounts receivable at March 31, 2019 and December 31, 2018, is $7,329 and $5,815, respectively, of unbilled accounts receivable related to advertising customers billed within a quarter subsequent to services rendered. Revenue Recognition The following table summarizes revenue from contracts with customers by revenue source for the three months ended March 31, 2019 and 2018.
The Company provides disaggregation of revenue based on the marketplace subscription versus advertising and other revenue classification in the table above and based on geographic region (see Note 12) as it believes these categories best depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. Topic 606 requires that the Company disclose the aggregate amount of transaction price that is allocated to performance obligations that have not yet been satisfied as of the relevant quarter end. However, the Company has applied the practical expedient available under Topic 606 to not disclose the amount of transaction price allocated to unsatisfied performance obligations when any such performance obligation was part of a contract having an original expected duration of one year or less. The Company does not have future obligations associated with marketplace revenue subscriptions or advertising and other services that extend beyond one year. For performance obligations not satisfied as of March 31, 2019, the nature of the performance obligations, the variable consideration and any consideration from contracts with customers not included in the transaction price is consistent with performance obligations satisfied as of March 31, 2019. The remaining duration is less than one year. Revenue recognized during the three months ended March 31, 2019 from amounts included in deferred revenue at the beginning of the period was approximately $8,792. Recent Accounting Pronouncements Adopted Lease Accounting In February 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) (as amended, “ASC 842”). ASC 842 requires a lessee to recognize most leases on the Unaudited Condensed Consolidated Balance Sheet but recognize expenses on the Unaudited Condensed Consolidated Income Statement in a manner similar to current practice. The update states that a lessee will recognize a lease liability for the obligation to make lease payments and a right-to-use asset for the right to use the underlying assets for the lease term. The Company adopted ASC 842 as of January 1, 2019, using the additional transition method offered through ASU No. 2018-11. This approach provides a method for recording existing leases at the adoption date and recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Lease Overview The Company’s operating lease obligations consist of various leases for office space in: Cambridge, Massachusetts; Detroit, Michigan; Los Angeles, California; Dublin, Ireland; and London, United Kingdom. The Detroit, Los Angeles and London leases are immaterial to the Company. On June 19, 2018, the Company entered into an operating lease in Cambridge, Massachusetts at 121 First St. for the lease of 48,393 square feet of office space with a non-cancellable lease term through 2033 with an option to extend the lease term for two additional periods of five years each. The Company subleases the fifth floor and records the sublease income in other income, net within the Unaudited Condensed Consolidated Income Statement. The sublease income is immaterial. On March 11, 2016, the Company entered into an operating lease in Cambridge, Massachusetts at 55 Cambridge Parkway for the lease of 51,923 square feet of office space with a non-cancellable lease term through 2024 with an option to extend the lease term for one additional period of five years. On October 8, 2014, the Company entered into an operating lease in Cambridge, Massachusetts at 2 Canal Park for the lease of 48,059 square feet of office space with a non-cancellable lease term through 2022 with an option to extend the lease term for one additional period of five years. Each of the three leases described above provides for leasehold improvement incentives and annual rent increases through the term of the lease. Each of the three leases above also has an associated letter of credit, which is recorded as restricted cash within the Unaudited Condensed Consolidated Balance Sheet. At March 31, 2019 and December 31, 2018, restricted cash was $2,668 and $2,671, respectively, and primarily related to cash held at a financial institution in an interest‑bearing cash account as collateral for the three letters of credit related to the contractual provisions for the Company’s building lease security deposits. At March 31, 2019 and December 31, 2018, portions of restricted cash were classified as a short-term asset and long‑term asset. Additionally, 121 First St. has an associated security deposit, which was recorded in other assets, net within the Unaudited Condensed Consolidated Balance Sheet. On August 12, 2013, the Company entered into an operating lease in Dublin, Ireland at Styne House, Upper Hatch St. for the lease of 13,345 square feet of office space with a non-cancellable term through 2023. The lease provided for a rent increase at the end of year five. The Company’s financing lease obligations consists of a lease for office equipment and is immaterial. Prior to adoption of ASC 842 The Company categorized leases at their inception as either operating or capital leases. On certain lease arrangements, the Company may have received rent holidays or other incentives. The Company recognized lease costs on a straight‑line basis once it achieved control of the space, without regard to deferred payment terms, such as rent holidays, that deferred the commencement date of required payments or escalating payment amounts. The Company recorded the difference between required lease payments and rent expense as deferred rent. Additionally, incentives received were treated as a reduction of costs over the term of the agreement, as they were considered an inseparable part of the lease agreement. Post adoption of ASC 842 Upon adoption, the Company elected the transition relief package, permitted within the standard, pursuant to which the Company did not reassess the classification of existing leases, whether any expired or existing contracts contain a lease, and whether existing leases have any initial direct costs. The Company also elected the practical expedient on not separating lease components from non-lease components for all leases. The Company reviews all material contacts for embedded leases to determine if they have a right-of-use asset. The Company recognizes rent expense on a straight-line basis over the lease period. The depreciable life of assets and leasehold improvement are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. The Company also made an accounting policy election to not recognize a lease liability or right-of-use asset on its Unaudited Condensed Consolidated Balance Sheet for leases with an initial term of twelve months or less, and instead recognize lease payments on the Unaudited Condensed Consolidated Income Statement on a straight-line basis over the lease term and variable lease payments that do not depend on an index or rate as expense in the period in which the achievement of the specified target that triggers the variable lease payments becomes probable. Adoption of the new standard resulted in the recording of net lease assets and lease liabilities of approximately $52,334 and $63,280, respectively, as of January 1, 2019. The standard did not materially impact the Unaudited Condensed Consolidated Statement of Cash Flows and had no impact on the Unaudited Condensed Consolidated Income Statement. During the three months ended March 31, 2019 and 2018, the Company recognized $2,448 and $1,672, respectively, of rent expense. The Company allocates lease costs across all departments based on headcount in the respective location. As of March 31, 2019, the weighted average remaining lease term was 9.9 years and the weighted average discount rate was 5.9%. As most of the Company’s leases do not provide an implicit rate, the Company uses an estimated incremental borrowing rate based on the information available at lease commencement in determining the present value of lease payments. The Company estimated the incremental borrowing rate based on the rate of interest the Company would have to pay to borrow a similar amount on a collateralized basis over a similar term. The Company has no historical debt transactions and a collateralized rate is estimated based on a group of peer companies. The Company uses the incremental borrowing rate on January 1, 2019 for leases that commenced prior to that date. Future minimum lease payments as of March 31, 2019 are as follows:
Options to extend lease terms are not included in the chart above as they are not reasonably certain of being exercised. Stock-Based Compensation In June 2018, the FASB issued ASU No. 2018-07, Compensation—Stock Compensation (Topic 718) (“ASU 2018-07”). ASU 2018-07 expands the scope of Topic 718, Compensation—Stock Compensation, to include share-based payment transactions for acquiring goods and services from non-employees. The amendments in this update state that an entity should apply the requirements of Topic 718 to non-employee awards except for specific guidance on inputs to an option pricing model and the attribution of cost (that is, the period of time over which share-based payment awards vest and the pattern of cost recognition over that period). The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. The Company has assessed the impact of this guidance on its Unaudited Condensed Consolidated Financial Statements and does not deem it to be material. The Company adopted the guidance on January 1, 2019. Internal-Use Software In August 2018, the FASB issued ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40) Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This update aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. This new standard requires companies to expense the capitalized implementation costs over the term of the hosting arrangement. Amounts expensed would be presented through operating expense, rather than depreciation or amortization. Accounting for the service component of a hosting arrangement remains unchanged. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted and an entity can elect to apply the new guidance on a prospective or retrospective basis. The Company adopted this standard effective January 1, 2019 and applied the guidance using a prospective transition method for each period presented. In Q1 2019, the Company launched an initiative designed to evaluate and enhance its enterprise applications. As a result, $876 of implementation costs associated with service contracts have been classified in other long-term assets in the Unaudited Condensed Balance Sheet as of March 31, 2019. The implementation costs relate to assets that had not been placed in service as of March 31, 2019. Recent Accounting Pronouncements Not Yet Adopted From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies and adopted by the Company on or prior to the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on its financial position or results of operations upon adoption. In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The new guidance simplifies the accounting for goodwill impairment by eliminating Step 2 of the goodwill impairment test. Under current guidance, Step 2 of the goodwill impairment test requires entities to calculate the implied fair value of goodwill in the same manner as the amount of goodwill recognized in a business combination by assigning the fair value of a reporting unit to all of the assets and liabilities of the reporting unit. The carrying value in excess of the implied fair value is recognized as goodwill impairment. Under the new standard, goodwill impairment is recognized based on Step 1 of the current guidance, which calculates the carrying value in excess of the reporting unit’s fair value. The new standard is effective beginning in January 2020, with early adoption permitted. The Company is currently assessing the impact that adopting this guidance will have on its Unaudited Condensed Consolidated Financial Statements. |

3. Acquisitions
On January 8, 2019, the Company, through CarGurus UK Limited, a company incorporated in England & Wales and a wholly owned subsidiary of CarGurus Ireland Limited (a company incorporated in Ireland and a wholly owned subsidiary of the Company) (the “Purchaser”), completed its acquisition of PistonHeads, a UK-based automotive website (“PistonHeads”), by acquiring the entire issued share capital of Haymarket New4 Ltd. (a company incorporated in England & Wales and now known as PistonHeads Holdco Limited, “NewCo”) from Haymarket Media Group Ltd., a company incorporated in England & Wales (the “Seller”), on the terms and subject to the conditions set forth in the Put and Call Option Agreement dated December 3, 2018, by and among the Purchaser, the Seller and Haymarket Group Limited, a company incorporated in England & Wales. The PistonHeads website hosts used car classifieds, articles and forums. The Purchaser paid an aggregate of 15,000 GBP, or approximately $19,139, to acquire the business, inclusive of 1,000 GBP, or approximately $1,276, being held in escrow to secure post-closing claims, subject to the terms and conditions of an escrow agreement between the Purchaser and the Seller. Upon completion of the acquisition, NewCo became a wholly owned subsidiary of the Purchaser. The business combination is intended to expand the Company’s consumer audience in the UK. As of March 31, 2019, the Company has incurred total acquisition-related costs of $649 related to the transaction.
The acquisition has been accounted for as a business combination under the acquisition method and, accordingly, the total purchase price is allocated to the intangible assets and goodwill. Acquired tangible assets and assumed liabilities are immaterial. The following table presents the preliminary purchase price allocation recorded in the Company's Unaudited Condensed Consolidated Balance Sheet as of the acquisition date:
Actual and pro forma results for these acquisitions have not been presented as the financial impact to the Company’s Unaudited Condensed Consolidated Financial Statements is not material. |

4. Fair Value of Financial Instruments Including Cash, Cash Equivalents and Investments
The following tables present, for each of the fair value levels, the Company’s assets that are measured at fair value on a recurring basis at March 31, 2019 and at December 31, 2018:
Certificates of deposit at March 31, 2019 and December 31, 2018 had maturity dates of one year or less.
The Company measures eligible assets and liabilities at fair value with changes in value recognized in earnings. There were no liabilities that were measured at fair value for the three months ended March 31, 2019. Fair value treatment may be elected either upon initial recognition of an eligible asset or liability or, for an existing asset or liability, if an event triggers a new basis of accounting. The Company did not elect to remeasure any of its existing financial assets or liabilities, and did not elect the fair value option for any financial assets and liabilities transacted in the three months ended March 31, 2019 or the year ended December 31, 2018. The Company considers all highly liquid investments with an original maturity of 90 days or less at the date of purchase to be cash equivalents. Investments not classified as cash equivalents with maturities one year or less from the balance sheet date are classified as short-term investments, while investments with maturities in excess of one year from the balance sheet date are classified as long-term investments. Management determines the appropriate classification of investments at the time of purchase, and re-evaluates such determination at each balance sheet date. Cash and cash equivalents primarily consist of cash on deposit with banks, and amounts held in interest-bearing money market accounts. Cash equivalents are carried at cost, which approximates their fair market value. The following is a summary of cash, cash equivalents, and investments as of March 31, 2019 and December 31, 2018.

| Earnings Per Share |
10. Earnings Per Share Net income per share for the three months ended March 31, 2019 and 2018 is computed by dividing net income by the weighted-average number of common shares outstanding during the reporting period. The Company computes the weighted-average number of common shares outstanding during the reporting period using the total number of shares of Class A common stock and Class B common stock outstanding as of the last day of the previous year end reporting period plus the weighted-average of any additional shares issued and outstanding during the reporting period. The Company has two classes of common stock authorized: Class A common stock and Class B common stock. The rights of the holders of Class A and Class B common stock are identical, except with respect to voting and conversion. Each share of Class A common stock is entitled to one vote per share and each share of Class B common stock is entitled to ten votes per share. Each share of Class B common stock is convertible into one share of Class A common stock at the option of the holder at any time or automatically upon certain events described in the Company’s amended and restated certificate of incorporation, including on either the death or voluntary termination of the Company’s Chief Executive Officer. The Company allocates undistributed earnings attributable to common stock between the common stock classes on a one‑to‑one basis when computing net income per share. As a result, basic and diluted net income per share of Class A common stock and per share of Class B common stock are equivalent. During the three months ended March 31, 2019, no holders of Class B common stock converted shares of Class B common stock to Class A common stock. During the three months ended March 31, 2018, holders of Class B common stock converted 7,534,710 shares of Class B common stock to Class A common stock. Diluted net income per share gives effect to all potentially dilutive securities. Potential dilutive securities for the three months ended March 31, 2019 and 2018 consist of shares of common stock issuable upon the exercise of stock options and shares of common stock issuable upon the vesting of restricted stock units (“RSUs”). The dilutive effect of these common stock equivalents is reflected in diluted earnings per share by application of the treasury stock method. For the three months ended March 31, 2019 and 2018, diluted net income per share was calculated by dividing net income by the weighted-average number of shares of common stock outstanding during the period plus the dilutive impact of stock options and shares of common stock issuable upon the vesting of RSUs. The following table presents a reconciliation of the numerator and denominator used in the calculation of basic and diluted net income per share:
There were no anti-dilutive securities for the three months ended March 31, 2018. The following potentially dilutive common stock equivalents have been excluded from the calculation of diluted weighted-average shares outstanding for the three months ended March 31, 2019, as their effect would have been anti-dilutive for the period presented:

11. Income Taxes
During the three months ended March 31, 2019, the Company recorded an income tax benefit of $3,503, representing an effective tax rate of (38.6)%. The effective tax rate for the three months ended March 31, 2019 was lower than the statutory tax rate of 21% principally due to excess stock deductions from the taxable compensation of share-based awards and federal and state research and development tax credits, partially offset by state and local income taxes.
During the three months ended March 31, 2018, the Company recorded income tax expense of $1,246, representing an effective tax rate of 18.5%. The effective tax rate for the three months ended March 31, 2018 was lower than the statutory tax rate of 21% principally due to federal and state research and development tax credits and excess stock deductions from the taxable compensation of share-based awards, partially offset by state and local income taxes.
In 2018, the Internal Revenue Service commenced a federal income tax audit with respect to the Company’s 2016 tax year. In 2019, the Internal Revenue Service commenced a federal employment tax audit with respect to the 2016 calendar year. |

12. Segment and Geographic Information The Company has two reportable segments, United States and International. Segment information is presented in the same manner as the Company’s chief operating decision maker (the “CODM”) reviews the Company’s operating results in assessing performance and allocating resources. The CODM reviews revenue and operating income (loss) for each reportable segment as a proxy for the operating performance of the Company’s United States and International operations. The Company’s Chief Executive Officer is the CODM on behalf of both reportable segments. The United States segment derives revenues from marketplace subscriptions, advertising services, and other revenues from customers within the United States. The International segment derives revenues from marketplace subscriptions, advertising services, and other revenues from customers outside of the United States. A majority of the Company’s operational overhead expenses, including technology and personnel costs, and other general and administrative costs associated with running the Company’s business, are incurred in the United States and not allocated to the International segment. Assets and costs discretely incurred by reportable segments, including depreciation and amortization, are included in the calculation of reportable segment income (loss) from operations. Segment operating income (loss) does not reflect the transfer pricing adjustments related to the Company’s foreign subsidiaries, which are recorded for statutory reporting purposes. Asset information is assessed and reviewed on a global basis. Information regarding the Company’s operations by segment and geographical area is presented as follows:

| Basis of Presentation |
Basis of Presentation The accompanying interim condensed consolidated financial statements (the “Unaudited Condensed Consolidated Financial Statements”) are unaudited. These Unaudited Condensed Consolidated Financial Statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto for the year ended December 31, 2018 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, filed with the Securities and Exchange Commission (“SEC”) on February 28, 2019 (the “2018 Annual Report”). The Unaudited Condensed Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the SEC. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. The Unaudited Condensed Consolidated Financial Statements reflect all adjustments, consisting of only normal recurring adjustments, necessary for the fair presentation of the Company’s financial position as of March 31, 2019 and December 31, 2018, results of operations, comprehensive income, changes in shareholders’ equity and cash flows for the three months ended March 31, 2019 and 2018. These interim period results are not necessarily indicative of the results to be expected for any other interim period or the full year. In the results of operations for the three months ended March 31, 2019 and 2018, the Company has separately presented interest income from other income, net due to the increase in amount during the three months ended March 31, 2019 as compared to the three months ended March 31, 2018. Additionally, the results of operations and statement of cash flows for the three months ended March 31, 2018, were adjusted due to the impact of the adoption of Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“Topic 606”). The accompanying Unaudited Condensed Consolidated Financial Statements reflect the application of certain significant accounting policies as described below and elsewhere in these notes to the Unaudited Condensed Consolidated Financial Statements. As of March 31, 2019, there have been no material changes in the Company's significant accounting policies from those that were disclosed in the 2018 Annual Report, other than those resulting from the adoption of ASC 842, which is described below. |

Subsequent Event Considerations The Company considers events or transactions that occur after the balance sheet date but prior to the issuance of the financial statements to provide additional evidence for certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated as required. The Company has evaluated all subsequent events and determined that there are no material recognized or unrecognized subsequent events requiring disclosure. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Use of Estimates |
Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Significant estimates relied upon in preparing these Unaudited Condensed Consolidated Financial Statements include revenue recognition and revenue reserve, the valuation of goodwill and intangible assets, the capitalization of product, technology, and development costs for website development and internal‑use software, and the recoverability of the Company’s net deferred tax assets and related valuation allowance. Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances. Actual results may differ from management’s estimates if these results differ from historical experience, or other assumptions do not turn out to be substantially accurate, even if such assumptions are reasonable when made. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Concentration of Credit Risk |
Concentration of Credit Risk The Company has no significant off‑balance sheet risk, such as foreign exchange contracts, option contracts, or other foreign hedging arrangements. Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash, cash equivalents, investments, and trade accounts receivable. The Company maintains its cash, cash equivalents, and investments principally with accredited financial institutions of high credit standing. Although the Company deposits its cash and investments with multiple financial institutions, its deposits, at times, may exceed federally insured limits. Credit risk with respect to accounts receivable is dispersed due to the large number of customers. The Company routinely assesses the creditworthiness of its customers. The Company generally has not experienced any material losses related to receivables from individual customers, or groups of customers. The Company does not require collateral. Due to these factors, no additional credit risk beyond amounts provided for collection losses is believed by management to be probable in the Company’s accounts receivable. For the three months ended March 31, 2019 and the year ended December 31, 2018, no individual customer accounted for more than 10% of total revenue. As of March 31, 2019, one customer accounted for 13% of net accounts receivable. As of December 31, 2018, two customers accounted for 21% and 14% of net accounts receivable, respectively. No other individual customer accounted for more than 10% of net accounts receivable at March 31, 2019 or December 31, 2018. Included in net accounts receivable at March 31, 2019 and December 31, 2018, is $7,329 and $5,815, respectively, of unbilled accounts receivable related to advertising customers billed within a quarter subsequent to services rendered. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Revenue Recognition |
Revenue Recognition The following table summarizes revenue from contracts with customers by revenue source for the three months ended March 31, 2019 and 2018.
The Company provides disaggregation of revenue based on the marketplace subscription versus advertising and other revenue classification in the table above and based on geographic region (see Note 12) as it believes these categories best depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. Topic 606 requires that the Company disclose the aggregate amount of transaction price that is allocated to performance obligations that have not yet been satisfied as of the relevant quarter end. However, the Company has applied the practical expedient available under Topic 606 to not disclose the amount of transaction price allocated to unsatisfied performance obligations when any such performance obligation was part of a contract having an original expected duration of one year or less. The Company does not have future obligations associated with marketplace revenue subscriptions or advertising and other services that extend beyond one year. For performance obligations not satisfied as of March 31, 2019, the nature of the performance obligations, the variable consideration and any consideration from contracts with customers not included in the transaction price is consistent with performance obligations satisfied as of March 31, 2019. The remaining duration is less than one year. Revenue recognized during the three months ended March 31, 2019 from amounts included in deferred revenue at the beginning of the period was approximately $8,792. |

| Recent Accounting Pronouncements Adopted |
Recent Accounting Pronouncements Adopted Lease Accounting In February 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) (as amended, “ASC 842”). ASC 842 requires a lessee to recognize most leases on the Unaudited Condensed Consolidated Balance Sheet but recognize expenses on the Unaudited Condensed Consolidated Income Statement in a manner similar to current practice. The update states that a lessee will recognize a lease liability for the obligation to make lease payments and a right-to-use asset for the right to use the underlying assets for the lease term. The Company adopted ASC 842 as of January 1, 2019, using the additional transition method offered through ASU No. 2018-11. This approach provides a method for recording existing leases at the adoption date and recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Lease Overview The Company’s operating lease obligations consist of various leases for office space in: Cambridge, Massachusetts; Detroit, Michigan; Los Angeles, California; Dublin, Ireland; and London, United Kingdom. The Detroit, Los Angeles and London leases are immaterial to the Company. On June 19, 2018, the Company entered into an operating lease in Cambridge, Massachusetts at 121 First St. for the lease of 48,393 square feet of office space with a non-cancellable lease term through 2033 with an option to extend the lease term for two additional periods of five years each. The Company subleases the fifth floor and records the sublease income in other income, net within the Unaudited Condensed Consolidated Income Statement. The sublease income is immaterial. On March 11, 2016, the Company entered into an operating lease in Cambridge, Massachusetts at 55 Cambridge Parkway for the lease of 51,923 square feet of office space with a non-cancellable lease term through 2024 with an option to extend the lease term for one additional period of five years. On October 8, 2014, the Company entered into an operating lease in Cambridge, Massachusetts at 2 Canal Park for the lease of 48,059 square feet of office space with a non-cancellable lease term through 2022 with an option to extend the lease term for one additional period of five years. Each of the three leases described above provides for leasehold improvement incentives and annual rent increases through the term of the lease. Each of the three leases above also has an associated letter of credit, which is recorded as restricted cash within the Unaudited Condensed Consolidated Balance Sheet. At March 31, 2019 and December 31, 2018, restricted cash was $2,668 and $2,671, respectively, and primarily related to cash held at a financial institution in an interest‑bearing cash account as collateral for the three letters of credit related to the contractual provisions for the Company’s building lease security deposits. At March 31, 2019 and December 31, 2018, portions of restricted cash were classified as a short-term asset and long‑term asset. Additionally, 121 First St. has an associated security deposit, which was recorded in other assets, net within the Unaudited Condensed Consolidated Balance Sheet. On August 12, 2013, the Company entered into an operating lease in Dublin, Ireland at Styne House, Upper Hatch St. for the lease of 13,345 square feet of office space with a non-cancellable term through 2023. The lease provided for a rent increase at the end of year five. The Company’s financing lease obligations consists of a lease for office equipment and is immaterial. Prior to adoption of ASC 842 The Company categorized leases at their inception as either operating or capital leases. On certain lease arrangements, the Company may have received rent holidays or other incentives. The Company recognized lease costs on a straight‑line basis once it achieved control of the space, without regard to deferred payment terms, such as rent holidays, that deferred the commencement date of required payments or escalating payment amounts. The Company recorded the difference between required lease payments and rent expense as deferred rent. Additionally, incentives received were treated as a reduction of costs over the term of the agreement, as they were considered an inseparable part of the lease agreement. Post adoption of ASC 842 Upon adoption, the Company elected the transition relief package, permitted within the standard, pursuant to which the Company did not reassess the classification of existing leases, whether any expired or existing contracts contain a lease, and whether existing leases have any initial direct costs. The Company also elected the practical expedient on not separating lease components from non-lease components for all leases. The Company reviews all material contacts for embedded leases to determine if they have a right-of-use asset. The Company recognizes rent expense on a straight-line basis over the lease period. The depreciable life of assets and leasehold improvement are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. The Company also made an accounting policy election to not recognize a lease liability or right-of-use asset on its Unaudited Condensed Consolidated Balance Sheet for leases with an initial term of twelve months or less, and instead recognize lease payments on the Unaudited Condensed Consolidated Income Statement on a straight-line basis over the lease term and variable lease payments that do not depend on an index or rate as expense in the period in which the achievement of the specified target that triggers the variable lease payments becomes probable. Adoption of the new standard resulted in the recording of net lease assets and lease liabilities of approximately $52,334 and $63,280, respectively, as of January 1, 2019. The standard did not materially impact the Unaudited Condensed Consolidated Statement of Cash Flows and had no impact on the Unaudited Condensed Consolidated Income Statement. During the three months ended March 31, 2019 and 2018, the Company recognized $2,448 and $1,672, respectively, of rent expense. The Company allocates lease costs across all departments based on headcount in the respective location. As of March 31, 2019, the weighted average remaining lease term was 9.9 years and the weighted average discount rate was 5.9%. As most of the Company’s leases do not provide an implicit rate, the Company uses an estimated incremental borrowing rate based on the information available at lease commencement in determining the present value of lease payments. The Company estimated the incremental borrowing rate based on the rate of interest the Company would have to pay to borrow a similar amount on a collateralized basis over a similar term. The Company has no historical debt transactions and a collateralized rate is estimated based on a group of peer companies. The Company uses the incremental borrowing rate on January 1, 2019 for leases that commenced prior to that date. Future minimum lease payments as of March 31, 2019 are as follows:
Options to extend lease terms are not included in the chart above as they are not reasonably certain of being exercised. Stock-Based Compensation In June 2018, the FASB issued ASU No. 2018-07, Compensation—Stock Compensation (Topic 718) (“ASU 2018-07”). ASU 2018-07 expands the scope of Topic 718, Compensation—Stock Compensation, to include share-based payment transactions for acquiring goods and services from non-employees. The amendments in this update state that an entity should apply the requirements of Topic 718 to non-employee awards except for specific guidance on inputs to an option pricing model and the attribution of cost (that is, the period of time over which share-based payment awards vest and the pattern of cost recognition over that period). The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. The Company has assessed the impact of this guidance on its Unaudited Condensed Consolidated Financial Statements and does not deem it to be material. The Company adopted the guidance on January 1, 2019. Internal-Use Software In August 2018, the FASB issued ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40) Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This update aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. This new standard requires companies to expense the capitalized implementation costs over the term of the hosting arrangement. Amounts expensed would be presented through operating expense, rather than depreciation or amortization. Accounting for the service component of a hosting arrangement remains unchanged. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted and an entity can elect to apply the new guidance on a prospective or retrospective basis. The Company adopted this standard effective January 1, 2019 and applied the guidance using a prospective transition method for each period presented. In Q1 2019, the Company launched an initiative designed to evaluate and enhance its enterprise applications. As a result, $876 of implementation costs associated with service contracts have been classified in other long-term assets in the Unaudited Condensed Balance Sheet as of March 31, 2019. The implementation costs relate to assets that had not been placed in service as of March 31, 2019. |

| Recent Accounting Pronouncements Not Yet Adopted |
Recent Accounting Pronouncements Not Yet Adopted From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies and adopted by the Company on or prior to the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on its financial position or results of operations upon adoption. In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The new guidance simplifies the accounting for goodwill impairment by eliminating Step 2 of the goodwill impairment test. Under current guidance, Step 2 of the goodwill impairment test requires entities to calculate the implied fair value of goodwill in the same manner as the amount of goodwill recognized in a business combination by assigning the fair value of a reporting unit to all of the assets and liabilities of the reporting unit. The carrying value in excess of the implied fair value is recognized as goodwill impairment. Under the new standard, goodwill impairment is recognized based on Step 1 of the current guidance, which calculates the carrying value in excess of the reporting unit’s fair value. The new standard is effective beginning in January 2020, with early adoption permitted. The Company is currently assessing the impact that adopting this guidance will have on its Unaudited Condensed Consolidated Financial Statements. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Fair Value of Financial Instruments Including Cash, Cash Equivalents and Investments | The Company measures eligible assets and liabilities at fair value with changes in value recognized in earnings. There were no liabilities that were measured at fair value for the three months ended March 31, 2019. Fair value treatment may be elected either upon initial recognition of an eligible asset or liability or, for an existing asset or liability, if an event triggers a new basis of accounting. The Company did not elect to remeasure any of its existing financial assets or liabilities, and did not elect the fair value option for any financial assets and liabilities transacted in the three months ended March 31, 2019 or the year ended December 31, 2018. The Company considers all highly liquid investments with an original maturity of 90 days or less at the date of purchase to be cash equivalents. Investments not classified as cash equivalents with maturities one year or less from the balance sheet date are classified as short-term investments, while investments with maturities in excess of one year from the balance sheet date are classified as long-term investments. Management determines the appropriate classification of investments at the time of purchase, and re-evaluates such determination at each balance sheet date. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Earnings Per Share |
Net income per share for the three months ended March 31, 2019 and 2018 is computed by dividing net income by the weighted-average number of common shares outstanding during the reporting period. The Company computes the weighted-average number of common shares outstanding during the reporting period using the total number of shares of Class A common stock and Class B common stock outstanding as of the last day of the previous year end reporting period plus the weighted-average of any additional shares issued and outstanding during the reporting period. The Company has two classes of common stock authorized: Class A common stock and Class B common stock. The rights of the holders of Class A and Class B common stock are identical, except with respect to voting and conversion. Each share of Class A common stock is entitled to one vote per share and each share of Class B common stock is entitled to ten votes per share. Each share of Class B common stock is convertible into one share of Class A common stock at the option of the holder at any time or automatically upon certain events described in the Company’s amended and restated certificate of incorporation, including on either the death or voluntary termination of the Company’s Chief Executive Officer. The Company allocates undistributed earnings attributable to common stock between the common stock classes on a one‑to‑one basis when computing net income per share. As a result, basic and diluted net income per share of Class A common stock and per share of Class B common stock are equivalent. |
