(“Caravel”) consummated the previously announced merger pursuant to a Business Combination Agreement and Plan of Merger, dated February 10, 2021 (the “Business Combination Agreement”), by and between Caravel, Fetch Merger Sub, Inc., a wholly owned subsidiary of Caravel (“Merger Sub”), and A Place for Rover, Inc. (“Legacy Rover”). Pursuant to the terms of the Business Combination Agreement, Merger Sub merged with and into Legacy Rover, with Legacy Rover continuing as the surviving entity and as a wholly owned subsidiary of Caravel (together with the other transactions described in the Business Combination Agreement, the “Merger”). On the Closing Date, Caravel changed its name from Nebula Caravel Acquisition Corp. to “Rover Group, Inc.” See Note 3—Reverse Recapitalization for additional information. Impact of COVID-19 The ongoing COVID-19 pandemic continues to impact communities globally, including in the markets we serve, which in turn impacts our business. Of particular importance is the pandemic’s impact on travel and the return of workers to their offices, as well as the increasing adoption of remote and hybrid working arrangements, which could result in fewer bookings and higher than average cancellation rates if the pandemic or permanent changes in working arrangements depresses travel or office attendance. The impact of the COVID-19 pandemic, including the resulting changes in travel and work behaviors, may continue to affect results in 2022 and beyond. The extent to which the pandemic will continue to impact the Company’s business, operating results and financial position will depend on future developments, which are highly uncertain, difficult to predict and beyond our knowledge and control. These may include but are not limited to the duration and spread of the pandemic, its severity, new variants and sub-variants, actions to contain the virus or treat its impact, the extent of the business disruption and financial impacts, and the magnitude and timing of such factors as economic and operating conditions. Liquidity The Company has incurred losses from operations and had an accumulated deficit of $347.6 million as of September 30, 2022. The Company has primarily funded its operations with proceeds from the issuance of redeemable convertible preferred stock, common stock and other equity transactions, proceeds from the Merger, and debt borrowings. As the Company continues to invest in expansion activities, management expects operating losses could continue in the foreseeable future. Management believes that the Company’s current cash and cash equivalents and investments will be sufficient to fund its operations for at least the next 12 months from the issuance of these condensed consolidated financial statements. The Company’s assessment of the period of time through which its financial resources will be adequate to support its operations is a forward-looking statement and involves risks and uncertainties. The Company’s actual results could vary as a result of its near and long-term future capital requirements that will depend on many factors. The Company has based its estimates on assumptions that may prove to be wrong, and it could use its available capital resources sooner than it currently expects. The Company may be required to seek additional equity or debt financing. If additional financing is required from outside sources, the Company may not be able to raise it on acceptable terms or at all. If the Company is unable to raise additional capital when desired, or if it cannot expand its operations or otherwise capitalize on its business opportunities because it lacks sufficient capital, its business, operating results, and financial condition would be adversely affected.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Principles of Consolidation and Basis of Presentation The condensed consolidated financial statements and accompanying notes include the accounts of the Company and its wholly owned subsidiaries, after elimination of all intercompany balances and transactions. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and the requirements of the U.S. Securities and Exchange Commission (the “SEC”) for interim financial information. Certain information and disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. Accordingly, these condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto for the year ended December 31, 2021. The information as of December 31, 2021 included in the condensed consolidated balance sheets was derived from those audited financial statements. For periods prior to the Merger, the reported share and per share amounts have been retroactively converted by the applicable exchange ratio with the exception of the authorized shares and shares reserved for issuance. See Note 3—Reverse Recapitalization for more information. The unaudited condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for the fair presentation of the Company’s financial information. The condensed consolidated results of operations for the nine months ended September 30, 2022 are not necessarily indicative of the results to be expected for the year ending December 31, 2022 or for any other future annual or interim period. Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated balance sheet and the reported amounts of revenue and expenses during the reporting period. Significant items subject to such estimates and assumptions, include, but are not limited to, the capitalization and estimated useful life of the Company’s internal-use software development costs, the assumptions used in the valuation of common stock prior to the reverse recapitalization, the assumptions used in the valuation of leases, legal contingencies, and stock-based compensation expense. These estimates and assumptions are based on information available as of the date of the condensed consolidated financial statements; therefore, actual results could differ from management’s estimates. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. The Company adjusts such estimates and assumptions when facts and circumstances dictate. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods. As future events and their effects cannot be determined with precision, actual results could materially differ from those estimates and assumptions. Segment Information The Company has one operating segment and one reportable segment. As the Company’s chief operating decision maker, the chief executive officer reviews financial information on a consolidated basis for purposes of allocating resources and evaluating financial performance. Substantially all long-lived assets are located in the United States and substantially all revenue is attributed to fees from pet parents and pet care providers based in the United States. Foreign Currencies Foreign currency transaction gains and losses are a result of the effect of exchange rate changes on transactions denominated in currencies other than the functional currency, including U.S. dollars. Gains and losses on those foreign currency transactions are included in determining net loss for the period of exchange and are recorded in other expense, net in the condensed consolidated statements of operations. The net effect of foreign currency losses was $0.2 million and $1.0 million for the three and nine months ended September 30, 2022, respectively, and was not material during the three and nine months ended September 30, 2021. Certain Significant Risks and Uncertainties The Company is subject to certain risks and challenges associated with other companies at a similar stage of development, including risks associated with: dependence on key personnel; marketing; adaptation to changing market dynamics and customer preferences; and potential competition including from larger companies that may have greater name recognition, longer operating histories, more and better established customer relationships and greater resources than the Company. The Company’s ability to provide a reliable platform largely depends on the efficient and consistent operation of its computer information systems and those of its third-party service providers. Any significant interruptions could harm the Company’s business and reputation and result in a loss of business. Further, there has been evidence that the Company has been the subject of cyber-attacks, and it is possible that it will be subject to similar attacks in the future. These attacks may be primarily aimed at interrupting the Company’s business, exposing it to financial losses, or exploiting information security vulnerabilities. To management’s knowledge, no prior attacks or breaches have, individually, or in the aggregate, resulted in any material liability to the Company, or any material disruption to the Company’s business. Concentrations of Credit Risk Financial instruments, which potentially subject the Company to concentrations of credit risk, consist of cash, investments and accounts receivable. The Company maintains cash balances that may exceed the insured limits set by the Federal Deposit Insurance Corporation. The Company reduces credit risk by placing cash and investment balances with major financial institutions that management assesses to be of high-credit quality and also limits purchases of debt securities to investment-grade securities. For the three and nine months ended September 30, 2022 and 2021, no individual pet care provider, pet parent, or affiliate represented 10% or more of the Company’s revenue. As of September 30, 2022 and December 31, 2021, accounts receivable was $49.6 million and $26.0 million, respectively, and was comprised primarily of amounts due from payment processors who collected payment from pet parents on behalf of the Company. Accounts receivable settle relatively quickly, and the Company’s historical experience of losses has not been significant. Revenue Recognition Marketplace Platform Revenue The Company operates an online marketplace that provides a platform for pet parents and pet care providers to communicate and arrange for pet care services. The Company derives its revenue principally from pet parents’ and pet care providers’ use of the Company’s platform and related services that enable pet care providers to offer, book, and fulfill pet care services. The Company enters into terms of service with pet care providers and pet parents who wish to use the Company’s platform. The terms of service define the rights and responsibilities of pet care providers and pet parents when using the Company’s platform as well as general payment terms. The Company charges a fixed percentage service fee for each arrangement of pet care services between the pet parent and the pet care provider on the Company’s platform (a booking). The fixed percentage service fees are established at the time a pet parent or pet care provider joined the platform and do not vary based on the volume of transactions. A booking defines the explicit fee from which the Company earns its fixed percentage service fee. The creation of a booking combined with the terms of service establish enforceable rights and obligations for the transaction. A contract exists between the pet care provider and the Company upon the creation of a booking and after the pet care providers’ cancellation period has lapsed. Pet parents are considered the Company’s customers to the extent that they pay a fixed percentage fee up to a fixed dollar amount to the Company for the booking. Similarly, a contract exists between the pet parent and the Company upon the creation of a booking and after the pet care providers’ cancellation period has lapsed. Pet parents pay for services at the time of booking. The Company considers the facilitation of the connection between pet care provider and pet parent to be the promise in the contracts. This is consistent with the terms of service, as well as the substance of what a pet care provider or pet parent is expecting from the use of the Company’s platform. While customers have access to the use of the platform, customer support, and other activities, these activities are not considered distinct from each other in the context of the overall arrangement, which is the facilitation of a connection between a pet care provider and a pet parent. As such, the Company has determined that its sole performance obligation is to facilitate a connection between pet care providers and pet parents through its platform. The Company’s performance obligation is satisfied at a point-in-time when the connection has been completed, which is when the pet care provider and pet parent have completed a booking, any related cancellation period has lapsed, and the related underlying pet care services have begun. The Company derives revenue from pet care providers and pet parents primarily in the United States, as well as Canada, the United Kingdom and Western Europe. From time to time, the Company issues credits or refunds to its pet parents or pet care providers as a result of customer satisfaction matters. Such amounts are and have historically been immaterial. Judgment is required in determining whether the Company is the principal or agent in transactions with pet care providers and pet parents. The Company evaluates the presentation of revenue on a gross or net basis based on whether it controls the service provided to the pet parent and is therefore the principal, or the Company arranges for other parties to provide the service to the pet parent and is therefore the agent. The Company has concluded it is the agent in transactions with pet care providers and pet parents because, among other factors, it is not responsible for the delivery of pet care services provided by the pet care provider to the pet parent. Accordingly, the Company recognizes revenue on a net basis, representing the fee the Company expects to receive in exchange for providing the access to the Company’s platform to pet care providers and pet parents. The Company has no significant financing components in its contracts with customers. The Company recognizes revenue net of any sales tax paid related to its revenue transactions. Provider Onboarding Revenue The Company earns revenue from non-refundable provider onboarding fees by completing quality assurance reviews of new pet care provider profiles and by arranging for background checks, which are performed by a third party. Pet care providers pay the onboarding fee at the time of sign up. The Company recognizes revenue related to provider onboarding services at a point-in-time upon satisfaction of the related performance obligation, determined to be the completion of the quality assurance review of the pet care provider's profile and background check. Pet Parent Deposits and Pet Care Provider Liabilities The Company records payments received from pet parents, excluding the revenue portion due to the Company, in advance of the related services being provided as pet parent deposits. As the related performance obligations are satisfied, these amounts are settled through our payment processor and derecognized. In addition, we hold pet care provider liabilities relating to stays completed prior to the implementation of our current payment processor and related systems where payment has not yet been requested by the pet care provider. The Company is subject to compliance with escheat laws applicable by jurisdiction where pet care providers do not claim the amounts owed to them for services rendered. Rover Guarantee In connection with services provided to facilitate the connections between pet care provider and pet parent, the Company provides a contractual guarantee to reimburse pet parents or pet care providers for certain expenses arising from injuries or other damages incurred during a service booked through the Company’s platform, subject to specified conditions (the “Rover Guarantee”). The Company’s obligation under the Rover Guarantee is accounted for in accordance with Accounting Standards Codification Topic 460, Guarantees . As a result, the Company estimates the fair value of the liability incurred in connection with providing the Rover Guarantee and records such amounts in accrued expenses and other current liabilities within the Company’s condensed consolidated balance sheets. Cost of Revenue (Exclusive of Depreciation and Amortization Shown Separately) Cost of revenue (exclusive of depreciation and amortization shown separately) includes fees paid to payment processors for credit card and other funding transactions, server hosting costs, internal-use software amortization, third-party costs for background checks for pet care providers, operations and support costs associated with onboarding new pet care providers, costs related to the Rover Guarantee, and other direct and indirect costs arising as a result of transactions that take place on the Company’s platform. Marketing Advertising expenses were $6.3 million and $20.4 million during the three and nine months ended September 30, 2022, respectively, and $4.7 million and $8.8 million during the three and nine months ended September 30, 2021, respectively. Equity Method Accounting The Company’s non-marketable equity investments are accounted for using the equity method of accounting. The Company uses the equity method if it has the ability to exercise significant influence, but not control, over the operating and financial policies of the investee. For investments accounted for using the equity method, the Company’s proportionate share of net income or loss based on the investee’s financial results is recorded in the condensed consolidated statements of operations within loss from equity method investments. Equity method investments for which the fair value option is elected are measured at fair value on a recurring basis with changes in fair value reflected in earnings. See Note 6—Investments and Note 7 — Fair Value for more information . Recently Adopted Accounting Pronouncements The Company is provided the option to adopt new or revised accounting guidance as an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) either (1) within the same periods as those otherwise applicable to public business entities, or (2) within the same time periods as private companies, including early adoption when permissible. With the exception of standards the Company elected to early adopt, when permissible, the Company has elected to adopt new or revised accounting guidance within the same time period as private companies, as indicated below. In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , as amended, which amends guidance on reporting credit losses for assets held at amortized cost basis and available-for-sale debt securities from an incurred loss methodology to an expected loss methodology. For assets held at amortized cost basis, the guidance eliminates the probable initial recognition threshold and instead requires an entity to reflect its current estimate of all expected credit losses. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the assets to present the net amount expected to be collected. For available-for-sale debt securities, credit losses are recorded through an allowance for credit losses, rather than a write-down, limited to the amount by which fair value is below amortized cost. Additional disclosures about significant estimates and credit quality are also required. The guidance is effective for the Company for the year beginning after December 15, 2022. The Company early adopted this standard on January 1, 2022 using the prospective transition method. The adoption of the new standard did not have a material impact on the Company’s condensed consolidated financial statements. In January 2020, the FASB issued ASU 2020-01, Investments-Equity Securities (Topic 321), Investments-Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) - Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 . This guidance addresses accounting for the transition into and out of the equity method and provides clarification of the interaction of rules for equity securities, the equity method of accounting, and forward contracts and purchase options on certain types of securities. The guidance is effective for the Company for the year beginning after December 15, 2021. The Company adopted this standard on January 1, 2022 using the prospective transition method. The adoption of the new standard did not have an immediate impact on the Company’s condensed consolidated financial statements. In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40) , which simplifies the accounting for convertible instruments by reducing the number of accounting models available for convertible debt instruments. This guidance also eliminates the treasury stock method to calculate diluted earnings per share for convertible instruments and requires the use of the if-converted method. The guidance is effective for the Company for the year beginning after December 15, 2023. The Company early adopted this standard on January 1, 2022 using the prospective transition method. The adoption of the new standard did not have an immediate impact on the Company’s condensed consolidated financial statements. In May 2021, the FASB issued ASU No. 2021-04, Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options . The ASU addresses the previous lack of specific guidance in the accounting standards codification related to modifications or exchanges of freestanding equity-classified written call options (such as warrants) by specifying the accounting for various modification scenarios. The guidance is effective for interim and annual periods beginning after December 15, 2021, with early adoption permitted. The Company adopted this standard on January 1, 2022 and will apply the amendments of this ASU prospectively to any modifications or exchanges of freestanding equity-classified warrants occurring on or after the effective date. The adoption of the new standard did not have an immediate impact on the Company’s condensed consolidated financial statements. In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805)—Accounting for Contract Assets and Contract Liabilities from Contracts with Customers . This ASU was issued to improve the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to the following: (1) recognition of an acquired contract liability; and (2) payment terms and their effect on subsequent revenue recognized by the acquirer. The amendments in this ASU require acquiring entities to apply Topic 606 to recognize and measure contract assets and contract liabilities in a business combination, whereas current GAAP requires that the acquirer measures such assets and liabilities at fair value on the acquisition date. The guidance is effective for the Company for the year beginning after December 15, 2023, with early adoption permitted. The Company early adopted this standard on January 1, 2022 using the prospective transition method. The adoption of the new standard did not have an immediate impact on the Company’s condensed consolidated financial statements, but the new guidance has been applied to all business combinations completed after the adoption date. In November 2021, the FASB issued ASU No. 2021-10 Disclosures by Business Entities about Government Assistance . The amendments in this ASU require the following annual disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy: (1) information about the nature of the transactions and the related accounting policy used to account for the transactions, (2) the line items on the balance sheet and income statement that are affected by the transactions, and the amounts applicable to each financial statement line item; and (3) significant terms and conditions of the transactions, including commitments and contingencies. The guidance is effective for the Company for the year beginning after December 15, 2021. The Company adopted this standard on January 1, 2022 using the prospective transition method. The adoption of the new standard did not have an immediate impact on the Company’s condensed consolidated financial statements. Recently Issued Accounting Pronouncements In March 2022, the FASB issued ASU No. 2022-02 Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. The amendment in this ASU provides an update to: (1) troubled debt restructurings guidance in Subtopic 310-40 and enhances disclosure requirements for certain loan refinancings and restructurings; and (2) requires public entities to disclose current period gross write-offs by year of origination for financing receivables and net investments in leases. The guidance is effective for the Company for the year beginning after December 15, 2022. The Company will adopt this standard on January 1, 2023 using the prospective transition method. We do not expect the adoption of the new standard to have a material impact on the Company’s consolidated financial statements but will continue to evaluate the new standard in future accounting periods. In June 2022, the FASB issued ASU No. 2022-03 Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restriction. The amendment in this ASU clarifies that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. This amendment also requires public entities to add certain disclosures for equity securities subject to contractual sale restrictions. The guidance is effective for the Company for the year beginning after December 15, 2023. The Company will adopt this standard on January 1, 2024 using the prospective transition method. We do not expect the adoption of the new standard to have a material impact on the Company’s consolidated financial statements but will continue to evaluate the new standard in future accounting periods.

Reverse Recapitalization [Abstract]
Reverse Recapitalization	Reverse Recapitalization On July 30, 2021, the Company completed the Merger and received net proceeds of $235.6 million, net of transaction costs of $32.7 million. In connection with the Merger, the Company raised $268.3 million of gross proceeds from (1) the contribution of $128.3 million of net cash held in Caravel’s trust account from its initial public offering, (2) $50.0 million from the sale of 5,000,000 shares of the Company’s Class A common stock, par value $0.0001 per share (“Class A Common Stock”), at $10.00 per share in a transaction exempt from the registration requirements of the Securities Act of 1933, and (3) $90.0 million from the sale of an aggregate of 9,000,000 shares of Class A Common Stock at $10.00 per share pursuant to the backstop subscription agreement with affiliates (and an assignee of such affiliates) of the sponsor of Caravel (the “Sponsor Backstop Subscription Agreement”). Immediately before the Merger, all of Legacy Rover’s outstanding warrants were net exercised for shares of Legacy Rover common stock. Upon the consummation of the Merger, all holders of Legacy Rover common stock and preferred stock received shares of the Company’s Class A Common Stock at a deemed value of $10.379 per share after giving effect to the applicable exchange ratio based on the completion of the following transactions contemplated by the Business Combination Agreement: • the conversion of all outstanding shares of Legacy Rover redeemable convertible preferred stock into shares of Legacy Rover common stock at the then-effective conversion rate as calculated pursuant to Legacy Rover’s certificate of incorporation; • the cancellation of each issued and outstanding share of Legacy Rover common stock (including shares of common stock resulting from the conversion of Legacy Rover redeemable convertible preferred stock) and the conversion into a number of shares of the Company’s Class A Common Stock equal to an exchange ratio of 1.0379 (“Exchange Ratio”); and • the conversion of all outstanding vested and unvested Legacy Rover stock options into options exercisable for shares of the Company’s Class A Common Stock with the same terms except for the number of shares exercisable and the exercise price, each of which were adjusted using the exchange ratio of 1.2006. No cash consideration was paid out to Legacy Rover stockholders as there was insufficient cash after Caravel common stockholders exercised their right to redeem shares for cash. In connection with the Merger, the Company incurred $32.7 million of transaction costs. These costs consisted of underwriting, legal, and other professional fees, of which $14.5 million was recorded to additional paid-in capital and the remaining $18.2 million related to liabilities assumed from Caravel that were settled immediately after Closing. The number of shares of Class A Common Stock issued immediately following the consummation of the Merger at July 30, 2021 was: Number of Shares Common stock of Caravel outstanding prior to the Merger 27,500,000 Less redemption of Caravel shares (14,677,808) Sponsor Earnout Shares outstanding prior to the Merger 6,875,000 Less forfeiture of Sponsor Earnout Shares (1) (975,873) Common stock of Caravel (1) 18,721,319 Shares issued in PIPE financing 5,000,000 Shares issued in Sponsor Backstop Subscription Agreement 8,000,000 Shares issued in Assignment Agreement 1,000,000 Merger and PIPE financing shares 32,721,319 Legacy Rover shares (2) 124,477,819 Total 157,199,138 _______________ (1) Upon the Closing, 3,437,500 shares held by Nebula Caravel Holdings, LLC, the sponsor of Caravel and a greater than five percent stockholder of the Company (the “Sponsor”), vested, 975,873 were forfeited and 2,461,627 shares remained outstanding and unvested (the “Sponsor Earnout Shares”). At Closing, the remaining 2,461,627 Sponsor Earnout Shares were subject to vesting conditions based upon the occurrence of certain triggering events. At the close of trading on September 29, 2021, pursuant to the Business Combination Agreement and the achievement of Triggering Events I and II (as defined in the Business Combination Agreement), 1,969,300 of the Sponsor Earnout Shares vested. (2) The number of Legacy Rover shares was determined from the 32,434,987 shares of Legacy Rover common stock and 87,496,938 shares of Legacy Rover redeemable convertible preferred stock outstanding, which were converted to an equal number of shares of Legacy Rover common stock upon the Closing, and then converted at the Exchange Ratio of 1.0379 to Class A Common Stock of the Company. All fractional shares were rounded down to the nearest whole share. The Merger was accounted for as a reverse recapitalization under GAAP because Legacy Rover has been determined to be the accounting acquirer under Financial Accounting Standards Board’s Accounting Standards Codification (“ASC”) Topic 805, Business Combinations . Under this method of accounting, Caravel was treated as the “acquired” company for financial reporting purposes. Accordingly, for accounting purposes, the financial statements of the Company represent a continuation of the financial statements of Legacy Rover with the Merger treated as the equivalent of Legacy Rover issuing stock for the net assets of Caravel, accompanied by a recapitalization. The net assets of Caravel are stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Merger are those of Legacy Rover. Legacy Rover was determined to be the accounting acquirer based on evaluation of the following facts and circumstances: • Legacy Rover stockholders comprising a relative majority of the voting power of the Company; • Legacy Rover will have the ability to nominate a majority of the members of the board of directors of the Company; • Legacy Rover’s operations prior to the acquisition comprising the only ongoing operations of the Company; • Legacy Rover’s senior management comprising a majority of the senior management of the Company; and • the Company substantially assuming the Legacy Rover name.

Business Combination and Asset Acquisition [Abstract]
Business Combinations	Business Combinations On June 15, 2022, the Company acquired all issued and outstanding stock of an early-stage company that operates a virtual dog training platform. The transaction was accounted for as a business combination. The total purchase price for this acquisition of $7.4 million includes a $1.6 million holdback for indemnity and subsequent adjustments that is expected to be paid within the 18-month holdback period. The purchase price was allocated as follows: $4.4 million to intangible assets (see Note 9—Goodwill and Intangible Assets for more information), ($1.0) million to net assets and liabilities assumed based on their estimated fair value on the acquisition date, and the remaining $4.0 million to goodwill. The goodwill from the acquisition is mainly attributable to expected synergies and other benefits. The goodwill is not tax deductible. The intangible assets will be amortized on a straight-line basis over their estimated useful lives of three Certain employees hired in conjunction with the acquisition received restricted stock unit awards and retention bonuses that are subject to service conditions. We account for these awards and bonuses as a post-business combination expense. The Company incurred no acquisition-related costs for the three months ended September 30, 2022. The Company incurred $0.4 million in acquisition-related costs for the nine months ended September 30, 2022, which were included in general and administrative expenses in the condensed consolidated statements of operations. Additional information existing as of the acquisition date but unknown to us may become known at a later time, such as matters related to intangible assets, goodwill, income taxes or other contingencies. In accordance with GAAP, if this occurs during the 12-month period subsequent to the acquisition date, we may update the amounts and allocations recorded as of the acquisition date. The results of operations for this acquisition have been included in the Company’s consolidated statements of operations since the date of acquisition. Actual and pro forma revenue and results of operations for the acquisition have not been presented because they would not have a material impact on the condensed consolidated results of operations.

The amortized cost and fair value of the available-for-sale investments and unrealized gains and losses were as follows (in thousands): September 30, 2022 Amortized Costs Gross Unrealized Gains Gross Unrealized Losses Fair Value Marketable securities: Commercial paper $ 46,665 $ — $ (59) $ 46,606 Corporate securities 39,386 — (423) 38,963 US Government securities 109,434 — (983) 108,451 Asset-backed securities 3,718 — (41) 3,677 Agency bonds 2,503 — (25) 2,478 Total marketable securities 201,706 — (1,531) 200,175 Other investments: Convertible notes 1,310 — (325) 985 Total other investments 1,310 — (325) 985 Total investments $ 203,016 $ — $ (1,856) $ 201,160 December 31, 2021 Amortized Costs Gross Unrealized Gains Gross Unrealized Losses Fair Value Marketable securities: Corporate securities $ 4,293 $ — $ (1) $ 4,292 Total marketable securities $ 4,293 $ — $ (1) $ 4,292 The contractual maturity of the available-for-sale investments were as follows (in thousands): September 30, 2022 Within 1 year 1 to 5 year More than 5 years Total Marketable securities: Commercial paper $ 46,606 $ — $ — $ 46,606 Corporate securities 27,291 11,672 — 38,963 US Government securities 92,762 15,689 — 108,451 Asset-backed securities — 3,677 — 3,677 Agency bonds 2,478 — — 2,478 Total marketable securities 169,137 31,038 — 200,175 Other investments: Convertible notes 985 — — 985 Total other investments 985 — — 985 Total investments $ 170,122 $ 31,038 $ — $ 201,160 December 31, 2021 Within 1 year 1 to 5 year More than 5 years Total Marketable securities: Corporate securities $ — $ 4,292 $ — $ 4,292 Total $ — $ 4,292 $ — $ 4,292 The Company believes there were no fundamental issues such as credit losses or other factors with respect to any of its available-for-sale securities. The unrealized losses on investments in fixed-maturity securities were caused primarily by interest rate changes. It is expected that the securities would not be settled at a price less than par value of the investments. Because the declines in fair value are attributable to changes in interest rates or market conditions and not credit quality, and because the Company has the ability and intent to hold its available-for-sale investments until a market price recovery or maturity, the Company has not recognized any credit loss reserves at September 30, 2022. Other Investments In July 2022, the Company entered into transaction agreements with Pioneer Square Labs (“PSL”) and entities affiliated with PSL, a start-up studio and venture capital fund of which one of the Company’s directors, Greg Gottesman, is a managing director and co-founder, to invest in an early-stage service for pet parents that is complementary to the Company’s current offerings (the “Investee”). The Company contributed intellectual property in the form of a nonexclusive license agreement in exchange for 5,000,000 shares of common stock, which represents 29% of the Investee’s diluted outstanding equity. The Company accounts for this investment under the equity method as it has significant influence over the Investee but does not hold a controlling financial interest. In July 2022, the Company also made an initial investment of $1.0 million in the Investee in the form of a convertible note, which has a maturity date of July 2023. In September 2022, the Company made an additional $0.3 million convertible note investment in the Investee, which has a maturity date of September 2023. The convertible notes accrue interest at a rate of 5% per year and are payable upon the maturity dates. The Investee may not prepay the convertible notes. If the Investee raises funds prior to the maturity dates of the convertible notes, then the Company will receive the full value of the convertible notes, including all accrued and unpaid interest, in the form of preferred stock in the Investee. The Company has elected to measure these convertible notes at fair value with changes in fair value reported in earnings (see Note 7—Fair Value for more information). PSL and the Company have roughly equivalent minority ownership positions in the Investee offering the services, and have customary rights afforded to investors in venture-backed companies. PSL will be reimbursed for certain start-up and formation costs by the entity and will provide, and be compensated for, certain services to the entity for a period of time after formation. Mr. Gottesman is not currently on the board of this entity and will not serve on its board unless approved by the Company’s board of directors. Mr. Gottesman holds a minority position in PSL. As of September 30, 2022, the carrying values of the Company’s convertible notes were $1.0 million, as recorded in prepaid expenses and other current assets within the condensed consolidated balance sheets. For both the three and nine months ended September 30, 2022, the Company recorded losses of $0.3 million within loss from equity method investments in the condensed consolidated statements of operations, representing its proportionate share of net income or loss based on the Investee’s financial results. As the Company’s basis in the equity method investment was zero, this loss resulted in a reduction to the carrying value of the convertible note investments. As discussed further in Note 7—Fair Value , the convertible note investments are measured at fair value. The carrying value of the convertible notes after the attribution of equity method losses is equal to the fair value of the convertible notes, so no incremental fair value adjustment was recorded for the three and nine months ended September 30, 2022. There were no impairment charges for the three and nine months ended September 30, 2022.

Fair Value	Fair Value The following table presents the placement in the fair value hierarchy of assets and liabilities that are measured at fair value on a recurring basis (in thousands): September 30, 2022 Level 1 Level 2 Level 3 Total Assets Cash equivalents: Money market funds $ 27,313 $ — $ — $ 27,313 Commercial paper — 25,215 — 25,215 Investments: Commercial paper — 46,606 — 46,606 Corporate securities — 38,963 — 38,963 US Government securities — 108,451 — 108,451 Asset-backed securities — 3,677 — 3,677 Agency bonds — 2,478 — 2,478 Other investments: Convertible notes — — 985 985 Total assets measured at fair value $ 27,313 $ 225,390 $ 985 $ 253,688 December 31, 2021 Level 1 Level 2 Level 3 Total Assets Cash equivalents: Money market funds $ 213,539 $ — $ — $ 213,539 Investments: Corporate securities — 4,292 — 4,292 Total assets measured at fair value $ 213,539 $ 4,292 $ — $ 217,831 Liabilities Derivative warrant liabilities (Public Warrants) $ 13,585 $ — $ — $ 13,585 Derivative warrant liabilities (Private Warrants) — 6,358 — 6,358 Total liabilities measured at fair value $ 13,585 $ 6,358 $ — $ 19,943 The following table provides a reconciliation of the beginning and ending balances for the level 3 financial assets measured at fair value using significant unobservable inputs (in thousands): Convertible Note Balance at December 31, 2021 $ — Additions during the period 1,310 Proportionate share of equity method losses (325) Balance at September 30, 2022 $ 985 The Company recognizes transfers between levels within the fair value hierarchy, if any, at the end of each period. There were no transfers of financial instruments between valuation levels during the periods presented. Valuation of Convertible Note Investments As described in Note 6 —Investments — Other Investments , the Company holds convertible note investments in the Investee that are measured at fair value. As of September 30, 2022, these convertible notes are held at a fair value of $1.0 million, which is equal to the initial cost of the investment less Rover’s cumulative share of the Investee’s net losses. The fair value of the notes is based predominantly on the credit quality of the underlying business and its ability to repay principal and interest, as well as the potential outcome of future equity financing transactions that may trigger the conversion feature provided by the notes. The carrying value of the convertible notes after the proportionate share of equity method losses is equal to the fair value of the convertible notes, so no incremental fair value adjustment was recorded for the three and nine months ended September 30, 2022. The Company classifies financial instruments in Level 3 of the fair value hierarchy when there is reliance on at least one significant unobservable input to the valuation model. In addition to these unobservable inputs, the valuation models for Level 3 financial instruments typically also rely on a number of inputs that are readily observable, either directly or indirectly. The Company’s assessment of a particular input to the fair value measurement requires management to make judgments and consider factors specific to the liability. The fair value hierarchy requires the use of observable market data when available in determining fair value. Valuation of Private Placement Warrant Derivative Liability In December 2021, the Company announced that, pursuant to the terms of the Warrant Agreement, it would redeem all of the outstanding private placement warrants (“Private Warrants”) held by Nebula Caravel Holdings, LLC, the sponsor of Caravel and a greater than five percent stockholder of the Company, and public warrants (“Public Warrants” and, collectively, “Warrants”) that remained outstanding at 5:00 p.m. New York City time on January 12, 2022 (the “Redemption Date”). As a result of the redemption offer under which the Private Warrants would be redeemed on terms substantially similar to those of the Public Warrants, there was a change in valuation technique and the estimated fair value of the Private Warrants was determined using the closing stock price of $2.47 of the Public Warrants on December 31, 2021. As a result, as of December 31, 2021, the Private Warrants were reclassified from Level 3 to Level 2 financial instruments within the fair value hierarchy. In January 2022, the Company issued 2,046,220 shares of Class A Common Stock related to the December 2021 and January 2022 cashless exercise of 5,425,349 Public Warrants and 2,574,164 Private Warrants, representing approximately 98.6% of the Public Warrants and 100% of the Private Warrants, respectively. Holders of Warrants received 0.2558 shares of Class A Common Stock per Warrant in lieu of receiving a redemption price of $0.10 per Warrant (the “Redemption Price”) . A total of 74,631 Public Warrants remained unexercised after the Redemption Date and broker protect period and the Company redeemed those unexercised Public Warrants. Pursuant to the redemption, the Public Warrants ceased trading on The Nasdaq Global Market effective as of the close of trading on the Redemption Date, and were delisted after market close on the Redemption Date. As of September 30, 2022, no Warrant liabilities were outstanding as the related carrying amount of the warrant liability was reclassified to stockholders’ equity during the first quarter 2022. The Company classifies financial instruments as Level 2 within the fair value hierarchy which are valued on the basis of prices from an orderly transaction between market participants provided by reputable dealers or pricing services. Prices of these securities are obtained through independent, third-party pricing services and include market quotations that may include both observable and unobservable inputs. In determining the value of a particular investment, pricing services may use certain information with respect to transactions in such investments, quotations from dealers, pricing matrices and market transactions in comparable investments and various relationships between investments. In determining the value of these Private Warrants, the Company may use certain information with respect to market transactions in substantially similar securities.

Debt Disclosure [Abstract]
Debt	Debt In March 2020, the Company borrowed $30.0 million under the subordinated credit facility. In April 2020, the Company was approved for and received a $8.1 million loan from the Small Business Administration’s Paycheck Protection Program (“PPP”). Upon the Closing, the Company repaid in full the subordinated credit facility of $30.0 million and the PPP loan of $8.1 million. Additionally, in accordance with the subordinated credit facility, the Company made a final termination payment of $0.9 million and accelerated $0.4 million of unamortized debt issuance costs at the termination of the subordinated credit facility. As of September 30, 2022 and December 31, 2021, the Company had no debt outstanding. Revolving Line of Credit At December 31, 2021, the Company had repaid in full all amounts owed under the facility, terminated all commitments and obligations under the revolving line of credit, was released from all security interests, mortgages, liens and encumbrances under the credit facility, and retained an unsecured $3.5 million letter of credit for the security deposit on its Seattle headquarters and Spokane office space. Subordinated Credit Facility The subordinated credit facility was a term loan advance. Subject to the terms and conditions of the subordinated credit facility, the lender agreed to make advances to the Company to the amount of $30.0 million during the draw period, which was available until June 30, 2020. After principal repayments, no term loan advance was able to be reborrowed. The term loan advance was interest only on a monthly basis. Outstanding principal and accrued interest were due at the maturity date. Interest accrued at the Prime Rate plus a margin of 4.25% per year. In connection with securing the term loan advance, the Company incurred $269,000 in costs related to originating the debt which were initially capitalized as debt issuance costs. Once the term loan advance of $30.0 million was drawn down in March 2020, the costs were recorded as a debt discount and amortized to interest expense over the term of the term loan advance. Upon the Closing, the Company repaid the full $30.0 million term loan advance and accrued interest of $0.2 million. The Company had collateralized the credit facility and the subordinated credit facility with substantially all of its tangible and intangible assets. The credit facility included several affirmative and negative covenants, as well as financial covenants. Financial covenants included minimum liquidity and minimum net revenue amounts and were applicable if the Company’s overall liquidity, as renegotiated in March 2021, was less than or equal to $65.0 million at the end of a reporting period. If the Company defaulted under the terms of the credit facility, it would not be permitted to draw additional funds on the revolving line of credit and the lenders could accelerate the Company’s obligation to pay all outstanding amounts. The Company was in compliance with all of its financial covenants as of the date of its full repayment of the term loan advance upon the Closing. Small Business Administration’s Paycheck Protection Program In April 2020, the Company entered into the PPP Promissory Note and Agreement, pursuant to which it incurred $8.1 million aggregate principal amount of term borrowings. The PPP loan was made under, and was subject to the terms and conditions of, the PPP which was established under the Coronavirus Aid, Relief, and Economic Security Act and was administered by the U.S. Small Business Administration. The term of the PPP loan was two years with a maturity date of April 2022 and accrued interest at a rate of 1.00% per year. Interest was payable monthly. Payments of principal and interest on the PPP loan were deferred until August 2021. The PPP loan was eligible for forgiveness if the proceeds were used for qualified purposes within a specified period. Upon the Closing, the Company repaid the PPP loan of $8.1 million and accrued interest of $0.1 million.

Commitments and Contingencies	Commitments and Contingencies Leases The Company leases certain office space in Seattle and Spokane, Washington and Barcelona, Spain with lease agreements expiring between 2023 and 2030. These leases require monthly lease payments that may be subject to annual increases throughout the lease term. Certain of these leases also include renewal options at the election of the Company to renew or extend the lease for an additional one In September 2018, the Company entered into a non-cancellable sublease agreement for a portion of one of its leased facilities that commenced on November 1, 2018. In February 2020, the Company amended the sublease to extend the term for an additional two years, and in May 2022 amended the sublease again to extend the term for one In April 2021, the Company entered into a non-cancellable sublease agreement for a portion of one of its leased facilities that commenced on September 1, 2021. As of September 30, 2022, under the terms of the sublease agreement, the Company will receive $1.1 million in base lease payments plus reimbursement of certain operating expenses over the remaining term of the sublease, which ends in August 2024.

The Company also enters into indemnification agreements with its officers and directors, and the Company’s certificate of incorporation and bylaws include similar indemnification obligations to its officers and directors. To date, there have been no claims under any indemnification provisions, therefore there is no accrual of such amounts for any of the periods presented. The Company is unable to determine the maximum potential impact of these indemnifications on the condensed consolidated financial statements and maintains director and officer insurance coverage that would generally enable it to recover a portion of any future amounts paid. Litigation and Other Contingencies From time to time, the Company is or may become party to litigation and subject to claims incurred in the ordinary course of business, including personal injury and indemnification claims, intellectual property claims, labor and employment claims, threatened claims, breach of contract claims, and other types of claims, class action and representative lawsuits, and actions brought by government authorities, alleging violations of employment classification laws, labor and other laws that would apply to employees, consumer protection laws, data protection laws, or other laws. In addition, in the ordinary course of business, the Company’s Trust & Safety team receives claims pursuant to the Rover Guarantee program, as well as claims and threats of legal action that arise from pet care services booked through the Company’s website and/or applications. Various parties have from time to time claimed, and may claim in the future, that the Company is liable for damages related to accidents or other incidents involving pets, pet parents, pet care providers, and third parties. The Company is involved in a number of legal proceedings concerning matters arising in connection with the conduct of its business activities, some of which are at preliminary stages and some of which seek an indeterminate amount of damages. The Company regularly evaluates the status of legal proceedings in which it is involved to assess whether a loss is probable or there is a reasonable possibility that a loss or additional loss may have been incurred to determine if accruals are appropriate. The Company accrues a liability when management believes information available prior to the issuance of the condensed consolidated financial statements indicates it is probable a loss has been incurred as of the date of the condensed consolidated financial statements and the amount of loss can be reasonably estimated. For some of the cases described below, management is unable to provide a meaningful estimate of the possible loss or range of possible loss because, among other reasons: (1) the proceedings are in preliminary stages; (2) specific damage amounts have not been sought; (3) damages sought are, in our view, unsupported and/or exaggerated; (4) there is uncertainty as to the outcome of pending appeals or motions; or (5) there are significant factual issues to be resolved. The Company adjusts its accruals to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case. Legal costs are expensed as incurred. Although the results of litigation and claims are inherently unpredictable, management concluded, based on currently available information, that other than with respect to the case captioned Melanie Sportsman v. A Place for Rover, Inc . discussed below there was not a reasonable possibility that the Company had incurred a material and estimable loss during the periods presented related to such loss contingencies. On August 22, 2018, a pet care provider filed a representative action under California’s Private Attorney General Act (“PAGA”) in California Superior Court, captioned Erika Miller v. A Place for Rover, Inc. , alleging that the Company misclassified pet care providers in California as independent contractors in violation of the California Labor Code and alleging various wage and hour claims under the California Labor Code. The plaintiff is seeking injunctive relief, civil penalties, attorney’s fees, and other forms of relief. The Company removed the case to the U.S. District Court for the Northern District of California (the “Court”). A nother pet care provider was substituted as the plaintiff in the case, now captioned Melanie Sportsman v. A Place for Rover, Inc . On May 6, 2021, the Court granted the Company’s motion for summary judgment and entered judgment in the Company’s favor, closing the case. On May 28, 2021, the plaintiff filed a notice of appeal of the Court’s dismissal with the U.S. Court of Appeals for the Ninth Circuit (the “Ninth Circuit”). On August 29, 2022, the Ninth Circuit heard oral argument in this appeal. Following the hearing, the Company engaged in mediation with the plaintiff on September 27, 2022 and October 19, 2022. On October 20, 2022, the Company entered into a binding settlement term sheet with the named plaintiff. The term sheet provides that the Company will make a total settlement payment of $18.0 million in full and final settlement of all claims that the named plaintiff and members of a proposed settlement class are bringing or could bring in the litigation, including claims under PAGA, the California Labor Code and similar statutes through final approval of the settlement agreement. The settlement class to be proposed consists of all pet care providers who performed at least one service in California booked through the Rover platform during the period from November 1, 2018 through the date on which the motion for preliminary approval of the settlement is filed with the Court. In addition, pet care providers who performed at least one service in California between October 1, 2017 and October 31, 2018 will receive more limited relief under a PAGA settlement. Final settlement is subject to, among other things, negotiation of a definitive settlement agreement not inconsistent with the terms in the term sheet and Court approval of such agreement. In settling the case, the Company is not admitting any wrongdoing or liability. The Company recorded this amount under general and administrative expense in the condensed consolidated statements of operations for the three and nine months ended September 30, 2022 and within accrued expenses and other current liabilities on the condensed consolidated balance sheets as of September 30, 2022. The Company expects to pay such settlement from existing cash and cash equivalents and investments once approved by the Court. On October 21, 2022, the Company and the named plaintiff made a joint motion to withdraw the appeal and remand the case to the Court for settlement approval. On October 27, 2022, the Ninth Circuit dismissed the appeal without prejudice to reinstatement in the event the Court declines to approve the settlement. On October 26, 2021, a pet care provider filed a putative class action complaint in the Superior Court of California, Los Angeles County, captioned Claire Rainey v. A Place for Rover, Inc. , alleging that the Company misclassified pet care providers in California as independent contractors in violation of the California Labor Code and alleging various wage and hour claims under the California Labor Code and unfair competition claims under the Business and Professions Code. The plaintiff is seeking injunctive relief, compensatory damages, civil penalties, attorney’s fees, and other forms of relief. On January 19, 2022, the Company removed the class action to the U.S. District Court for the Central District of California. On July 18, 2022, the court granted the Company’s motion to compel arbitration. On January 21, 2022, the same plaintiff filed a representative action under PAGA in the Superior Court of California, Los Angeles County, captioned Claire Rainey v. A Place for Rover, Inc., alleging that the Company misclassified pet care providers in California as independent contractors in violation of the California Labor Code and alleging various wage and hour claims under the California Labor Code. The plaintiff is seeking civil penalties under PAGA, attorney’s fees, and other forms of relief. On March 18, 2022, the Company removed the PAGA lawsuit to the U.S. District Court for the Central District of California. On July 29, 2022, the Company filed a motion to compel arbitration. On September 1, 2022, the court granted the Company’s motion to compel arbitration, ordering arbitration of the plaintiff’s individual PAGA claims and dismissing the plaintiff’s representative PAGA claims. The Company has denied or intends to deny the allegations of wrongdoing and intends to vigorously defend against the claims in these lawsuits. The Company does not currently believe that a material loss related to these lawsuits is probable. Given the inherent uncertainties of litigation, the ultimate outcome of the ongoing matters cannot be predicted with certainty. While litigation is inherently unpredictable, the Company believes it has valid defenses with respect to the legal matters pending against it. Nevertheless, the condensed consolidated financial statements could be materially adversely affected in a particular period by the resolution of one or more of these contingencies. Liabilities established to provide for contingencies are adjusted as further information develops, circumstances change, or contingencies are resolved; and such changes are recorded in the accompanying condensed consolidated statements of operations during the period of the change and reflected in accrued expenses and other current liabilities on the accompanying condensed consolidated balance sheets. Regardless of the outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources, and other factors. The Company may also find itself at greater risk to outside party claims or regulatory actions as it increases and continues its operations in jurisdictions where the laws with respect to the potential liability of online marketplaces or the employment classification of care providers who use online marketplaces are uncertain, unfavorable or unclear. Additionally, from time to time, the Company has been or may become subject to audit by taxing authorities or subject to other forms of inspection or audit, including audits related to employment classification matters. Due to the uncertainties inherent in the final outcome of such matters, the Company can give no assurance that it will prevail in such matters which could have an adverse effect on the Company’s business. As of September 30, 2022 and except for matters and claims noted above, the Company was not aware of any currently pending legal matters or claims, individually or in the aggregate, that are expected to have a material adverse impact on its condensed consolidated financial statements.

The Warrants became exercisable on December 11, 2021 and expire on July 30, 2026, at 5:00 p.m. New York City time, or earlier upon redemption or liquidation. In December 2021, the Company announced that, pursuant to the terms of the Warrant Agreement, it would redeem all of the Warrants that remained outstanding. On the Redemption Date, any Warrants that remained unexercised became void and no longer exercisable, and the holders of those Warrants were entitled to receive only the redemption price of $0.10 per Warrant. In January 2022, the Company issued 2,046,220 shares of Class A Common Stock related to the December 2021 and January 2022 cashless exercise of 5,425,349 Public Warrants and 2,574,164 Private Warrants, representing approximately 98.6% of the Public Warrants and 100% of the Private Warrants, respectively. Holders of Warrants who chose to cashless exercise their Warrants received 0.2558 shares of Class A Common Stock per Warrant in lieu of receiving the Redemption Price. A total of 74,631 Public Warrants remained unexercised after the Redemption Date and broker protect period and the Company redeemed those unexercised Public Warrants.

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation 2021 Equity Incentive Plan In connection with the Closing, the Company adopted the 2021 Equity Incentive Plan (the “2021 Plan”) under which 17.2 million shares of Class A Common Stock were initially reserved for issuance, plus up to 20.4 million shares subject to stock options that were assumed in the Merger and expire or otherwise terminate without having been exercised in full, are tendered to or withheld by the Company for payment of an exercise price or for tax withholding obligations, or are forfeited to or repurchased by the Company due to failure to vest. The 2021 Plan permits the grant of incentive and non-qualified stock options, restricted stock, restricted stock units and other stock-based awards to employees, directors, and consultants of the Company. As of September 30, 2022, the Company had 7.7 million shares of Class A Common Stock reserved for future issuance under the 2021 Plan, which includes shares subject to stock options that were assumed in the Merger that expired or otherwise terminated without having been exercised in full or were forfeited due to failure to vest. Upon the Closing, each option to purchase shares of Legacy Rover common stock that was outstanding, whether vested or unvested, was automatically converted into an option to purchase shares of the Company’s Class A Common Stock with the same terms except for the number of shares exercisable and the exercise price, using the exchange ratio of 1.2006 (“Option Exchange Ratio”). For periods prior to the Merger, the number of options and per share amounts have been retroactively converted by applying the Option Exchange Ratio. Equity Awards Available for Grant A summary of equity awards available for grant is as follows (in thousands): Equity Available Balances as of December 31, 2021 14,083 Equity awards authorized — Equity awards granted (7,294) Equity awards canceled and forfeited 903 Balances as of September 30, 2022 7,692 Stock Options A summary of stock option activity is as follows (in thousands, except per share amounts and years): Number of Weighted- Weighted- Aggregate Balance as of December 31, 2021 18,058 $ 1.60 6.1 $ 147,219 Options exercised (2,886) 0.95 Options canceled and forfeited (251) 2.20 Balances as of September 30, 2022 14,921 $ 1.71 5.6 $ 24,400 Options vested and exercisable – September 30, 2022 13,067 $ 1.66 5.3 $ 21,957 There were no options granted during the nine months ended September 30, 2022 and 2021. The aggregate intrinsic value of stock options exercised during the three and nine months ended September 30, 2022 and was $0.3 million and $12.5 million, respectively, and was $14.5 million and $19.9 million during the three and nine months ended September 30, 2021, respectively. The fair value of options vested during the three and nine months ended September 30, 2022 was $0.6 million and $2.1 million, respectively, and was $0.9 million and $2.9 million during the three and nine months ended September 30, 2021, respectively. Restricted Stock Units Restricted stock units (“RSUs”) are measured at the fair market value of the underlying stock at the grant date and the expense is recognized over the requisite service period. The service-based vesting condition for these awards is generally satisfied over four years. A summary of RSU activity is as follows (in thousands, except per share amounts): Number of Weighted- Aggregate Unvested December 31, 2021 2,863 $ 12.02 Granted 7,294 4.85 Vested (1,293) 9.02 Forfeited (652) 7.49 Unvested September 30, 2022 8,212 $ 6.48 $ 27,428 The total fair value of RSUs vested during the three and nine months ended September 30, 2022 was $5.7 million and $11.7 million, respectively, and there were no RSUs vested during the three and nine months ended September 30, 2021. Stock-Based Compensation The following table summarizes stock-based compensation expense recorded in each component of operating expenses in the Company’s condensed consolidated statements of operations for the presented periods (in thousands): Three Months Ended Nine Months Ended 2022 2021 2022 2021 Operations and support $ 473 $ 43 $ 1,214 $ 144 Marketing 302 71 858 238 Product development 1,293 287 4,157 981 General and administrative 2,813 593 7,796 1,779 Total stock-based compensation expense $ 4,881 $ 994 $ 14,025 $ 3,142 No material income tax benefit related to stock-based compensation was recorded during the three and nine months ended September 30, 2022 and 2021 as the Company maintained a full valuation allowance against its net deferred tax assets within the United States. As of September 30, 2022, total unrecognized compensation cost related to unvested stock options was $1.9 million, which was expected to be recognized over a weighted average remaining service period of 1.1 years. As of September 30, 2022, total unrecognized compensation cost related to unvested RSUs was $50.7 million, which was expected to be recognized over a weighted average remaining service period of 3.0 years.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s tax provision for interim periods is determined using an estimated annual effective tax rate, adjusted for discrete items in the related period. The effective tax rates for the three and nine months ended September 30, 2022 were (0.3)% and 0.6%, respectively, and 0.0% and 0.3% for the three and nine months ended September 30, 2021, respectively. The change in effective tax rate is primarily due to a discrete item in the second quarter 2021 related to the enacted tax law change increasing the general United Kingdom tax rate from 19% to 25%, effective April 1, 2023 and the effect of U.S. losses being excluded from our estimated annual effective tax rate due to recording a full valuation allowance on the U.S. deferred tax assets. This is partially offset by a U.S. deferred tax benefit recorded in the nine months ended September 30, 2022, resulting from a reduction in the Company’s valuation allowance due to an increase in the deferred tax liability associated with the acquired intangible assets from a business combination, as discussed in Note 4—Business Combinations . During the three and nine months ended September 30, 2022, the amount of gross unrecognized tax benefits increased by $16,000 and $41,000, respectively, of which all, if recognized, would not affect the effective tax rate as these unrecognized tax benefits would increase deferred tax assets that would be subject to a full valuation allowance.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2022
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation and Basis of PresentationThe condensed consolidated financial statements and accompanying notes include the accounts of the Company and its wholly owned subsidiaries, after elimination of all intercompany balances and transactions.
Basis of Presentation	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and the requirements of the U.S. Securities and Exchange Commission (the “SEC”) for interim financial information. Certain information and disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. Accordingly, these condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto for the year ended December 31, 2021. The information as of December 31, 2021 included in the condensed consolidated balance sheets was derived from those audited financial statements. For periods prior to the Merger, the reported share and per share amounts have been retroactively converted by the applicable exchange ratio with the exception of the authorized shares and shares reserved for issuance. See Note 3—Reverse Recapitalization for more information.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated balance sheet and the reported amounts of revenue and expenses during the reporting period. Significant items subject to such estimates and assumptions, include, but are not limited to, the capitalization and estimated useful life of the Company’s internal-use software development costs, the assumptions used in the valuation of common stock prior to the reverse recapitalization, the assumptions used in the valuation of leases, legal contingencies, and stock-based compensation expense. These estimates and assumptions are based on information available as of the date of the condensed consolidated financial statements; therefore, actual results could differ from management’s estimates. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. The Company adjusts such estimates and assumptions when facts and circumstances dictate. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods. As future events and their effects cannot be determined with precision, actual results could materially differ from those estimates and assumptions.
Segment Information	Segment Information The Company has one operating segment and one reportable segment. As the Company’s chief operating decision maker, the chief executive officer reviews financial information on a consolidated basis for purposes of allocating resources and evaluating financial performance. Substantially all long-lived assets are located in the United States and substantially all revenue is attributed to fees from pet parents and pet care providers based in the United States.
Foreign Currencies	Foreign CurrenciesForeign currency transaction gains and losses are a result of the effect of exchange rate changes on transactions denominated in currencies other than the functional currency, including U.S. dollars. Gains and losses on those foreign currency transactions are included in determining net loss for the period of exchange and are recorded in other expense, net in the condensed consolidated statements of operations.
Certain Significant Risks and Uncertainties	Certain Significant Risks and Uncertainties The Company is subject to certain risks and challenges associated with other companies at a similar stage of development, including risks associated with: dependence on key personnel; marketing; adaptation to changing market dynamics and customer preferences; and potential competition including from larger companies that may have greater name recognition, longer operating histories, more and better established customer relationships and greater resources than the Company.
Concentrations of Credit Risk	Concentrations of Credit RiskFinancial instruments, which potentially subject the Company to concentrations of credit risk, consist of cash, investments and accounts receivable. The Company maintains cash balances that may exceed the insured limits set by the Federal Deposit Insurance Corporation. The Company reduces credit risk by placing cash and investment balances with major financial institutions that management assesses to be of high-credit quality and also limits purchases of debt securities to investment-grade securities.
Revenue Recognition	Revenue Recognition Marketplace Platform Revenue The Company operates an online marketplace that provides a platform for pet parents and pet care providers to communicate and arrange for pet care services. The Company derives its revenue principally from pet parents’ and pet care providers’ use of the Company’s platform and related services that enable pet care providers to offer, book, and fulfill pet care services. The Company enters into terms of service with pet care providers and pet parents who wish to use the Company’s platform. The terms of service define the rights and responsibilities of pet care providers and pet parents when using the Company’s platform as well as general payment terms. The Company charges a fixed percentage service fee for each arrangement of pet care services between the pet parent and the pet care provider on the Company’s platform (a booking). The fixed percentage service fees are established at the time a pet parent or pet care provider joined the platform and do not vary based on the volume of transactions. A booking defines the explicit fee from which the Company earns its fixed percentage service fee. The creation of a booking combined with the terms of service establish enforceable rights and obligations for the transaction. A contract exists between the pet care provider and the Company upon the creation of a booking and after the pet care providers’ cancellation period has lapsed. Pet parents are considered the Company’s customers to the extent that they pay a fixed percentage fee up to a fixed dollar amount to the Company for the booking. Similarly, a contract exists between the pet parent and the Company upon the creation of a booking and after the pet care providers’ cancellation period has lapsed. Pet parents pay for services at the time of booking. The Company considers the facilitation of the connection between pet care provider and pet parent to be the promise in the contracts. This is consistent with the terms of service, as well as the substance of what a pet care provider or pet parent is expecting from the use of the Company’s platform. While customers have access to the use of the platform, customer support, and other activities, these activities are not considered distinct from each other in the context of the overall arrangement, which is the facilitation of a connection between a pet care provider and a pet parent. As such, the Company has determined that its sole performance obligation is to facilitate a connection between pet care providers and pet parents through its platform. The Company’s performance obligation is satisfied at a point-in-time when the connection has been completed, which is when the pet care provider and pet parent have completed a booking, any related cancellation period has lapsed, and the related underlying pet care services have begun. The Company derives revenue from pet care providers and pet parents primarily in the United States, as well as Canada, the United Kingdom and Western Europe. From time to time, the Company issues credits or refunds to its pet parents or pet care providers as a result of customer satisfaction matters. Such amounts are and have historically been immaterial. Judgment is required in determining whether the Company is the principal or agent in transactions with pet care providers and pet parents. The Company evaluates the presentation of revenue on a gross or net basis based on whether it controls the service provided to the pet parent and is therefore the principal, or the Company arranges for other parties to provide the service to the pet parent and is therefore the agent. The Company has concluded it is the agent in transactions with pet care providers and pet parents because, among other factors, it is not responsible for the delivery of pet care services provided by the pet care provider to the pet parent. Accordingly, the Company recognizes revenue on a net basis, representing the fee the Company expects to receive in exchange for providing the access to the Company’s platform to pet care providers and pet parents. The Company has no significant financing components in its contracts with customers. The Company recognizes revenue net of any sales tax paid related to its revenue transactions. Provider Onboarding Revenue The Company earns revenue from non-refundable provider onboarding fees by completing quality assurance reviews of new pet care provider profiles and by arranging for background checks, which are performed by a third party. Pet care providers pay the onboarding fee at the time of sign up. The Company recognizes revenue related to provider onboarding services at a point-in-time upon satisfaction of the related performance obligation, determined to be the completion of the quality assurance review of the pet care provider's profile and background check. Pet Parent Deposits and Pet Care Provider Liabilities The Company records payments received from pet parents, excluding the revenue portion due to the Company, in advance of the related services being provided as pet parent deposits. As the related performance obligations are satisfied, these amounts are settled through our payment processor and derecognized. In addition, we hold pet care provider liabilities relating to stays completed prior to the implementation of our current payment processor and related systems where payment has not yet been requested by the pet care provider. The Company is subject to compliance with escheat laws applicable by jurisdiction where pet care providers do not claim the amounts owed to them for services rendered. Rover Guarantee In connection with services provided to facilitate the connections between pet care provider and pet parent, the Company provides a contractual guarantee to reimburse pet parents or pet care providers for certain expenses arising from injuries or other damages incurred during a service booked through the Company’s platform, subject to specified conditions (the “Rover Guarantee”). The Company’s obligation under the Rover Guarantee is accounted for in accordance with Accounting Standards Codification Topic 460, Guarantees . As a result, the Company estimates the fair value of the liability incurred in connection with providing the Rover Guarantee and records such amounts in accrued expenses and other current liabilities within the Company’s condensed consolidated balance sheets. Cost of Revenue (Exclusive of Depreciation and Amortization Shown Separately)
Equity Method Accounting	Equity Method Accounting The Company’s non-marketable equity investments are accounted for using the equity method of accounting. The Company uses the equity method if it has the ability to exercise significant influence, but not control, over the operating and financial policies of the investee. For investments accounted for using the equity method, the Company’s proportionate share of net income or loss based on the investee’s financial results is recorded in the condensed consolidated statements of operations
Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements The Company is provided the option to adopt new or revised accounting guidance as an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) either (1) within the same periods as those otherwise applicable to public business entities, or (2) within the same time periods as private companies, including early adoption when permissible. With the exception of standards the Company elected to early adopt, when permissible, the Company has elected to adopt new or revised accounting guidance within the same time period as private companies, as indicated below. In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , as amended, which amends guidance on reporting credit losses for assets held at amortized cost basis and available-for-sale debt securities from an incurred loss methodology to an expected loss methodology. For assets held at amortized cost basis, the guidance eliminates the probable initial recognition threshold and instead requires an entity to reflect its current estimate of all expected credit losses. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the assets to present the net amount expected to be collected. For available-for-sale debt securities, credit losses are recorded through an allowance for credit losses, rather than a write-down, limited to the amount by which fair value is below amortized cost. Additional disclosures about significant estimates and credit quality are also required. The guidance is effective for the Company for the year beginning after December 15, 2022. The Company early adopted this standard on January 1, 2022 using the prospective transition method. The adoption of the new standard did not have a material impact on the Company’s condensed consolidated financial statements. In January 2020, the FASB issued ASU 2020-01, Investments-Equity Securities (Topic 321), Investments-Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) - Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 . This guidance addresses accounting for the transition into and out of the equity method and provides clarification of the interaction of rules for equity securities, the equity method of accounting, and forward contracts and purchase options on certain types of securities. The guidance is effective for the Company for the year beginning after December 15, 2021. The Company adopted this standard on January 1, 2022 using the prospective transition method. The adoption of the new standard did not have an immediate impact on the Company’s condensed consolidated financial statements. In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40) , which simplifies the accounting for convertible instruments by reducing the number of accounting models available for convertible debt instruments. This guidance also eliminates the treasury stock method to calculate diluted earnings per share for convertible instruments and requires the use of the if-converted method. The guidance is effective for the Company for the year beginning after December 15, 2023. The Company early adopted this standard on January 1, 2022 using the prospective transition method. The adoption of the new standard did not have an immediate impact on the Company’s condensed consolidated financial statements. In May 2021, the FASB issued ASU No. 2021-04, Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options . The ASU addresses the previous lack of specific guidance in the accounting standards codification related to modifications or exchanges of freestanding equity-classified written call options (such as warrants) by specifying the accounting for various modification scenarios. The guidance is effective for interim and annual periods beginning after December 15, 2021, with early adoption permitted. The Company adopted this standard on January 1, 2022 and will apply the amendments of this ASU prospectively to any modifications or exchanges of freestanding equity-classified warrants occurring on or after the effective date. The adoption of the new standard did not have an immediate impact on the Company’s condensed consolidated financial statements. In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805)—Accounting for Contract Assets and Contract Liabilities from Contracts with Customers . This ASU was issued to improve the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to the following: (1) recognition of an acquired contract liability; and (2) payment terms and their effect on subsequent revenue recognized by the acquirer. The amendments in this ASU require acquiring entities to apply Topic 606 to recognize and measure contract assets and contract liabilities in a business combination, whereas current GAAP requires that the acquirer measures such assets and liabilities at fair value on the acquisition date. The guidance is effective for the Company for the year beginning after December 15, 2023, with early adoption permitted. The Company early adopted this standard on January 1, 2022 using the prospective transition method. The adoption of the new standard did not have an immediate impact on the Company’s condensed consolidated financial statements, but the new guidance has been applied to all business combinations completed after the adoption date. In November 2021, the FASB issued ASU No. 2021-10 Disclosures by Business Entities about Government Assistance . The amendments in this ASU require the following annual disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy: (1) information about the nature of the transactions and the related accounting policy used to account for the transactions, (2) the line items on the balance sheet and income statement that are affected by the transactions, and the amounts applicable to each financial statement line item; and (3) significant terms and conditions of the transactions, including commitments and contingencies. The guidance is effective for the Company for the year beginning after December 15, 2021. The Company adopted this standard on January 1, 2022 using the prospective transition method. The adoption of the new standard did not have an immediate impact on the Company’s condensed consolidated financial statements. Recently Issued Accounting Pronouncements In March 2022, the FASB issued ASU No. 2022-02 Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. The amendment in this ASU provides an update to: (1) troubled debt restructurings guidance in Subtopic 310-40 and enhances disclosure requirements for certain loan refinancings and restructurings; and (2) requires public entities to disclose current period gross write-offs by year of origination for financing receivables and net investments in leases. The guidance is effective for the Company for the year beginning after December 15, 2022. The Company will adopt this standard on January 1, 2023 using the prospective transition method. We do not expect the adoption of the new standard to have a material impact on the Company’s consolidated financial statements but will continue to evaluate the new standard in future accounting periods. In June 2022, the FASB issued ASU No. 2022-03 Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restriction. The amendment in this ASU clarifies that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. This amendment also requires public entities to add certain disclosures for equity securities subject to contractual sale restrictions. The guidance is effective for the Company for the year beginning after December 15, 2023. The Company will adopt this standard on January 1, 2024 using the prospective transition method. We do not expect the adoption of the new standard to have a material impact on the Company’s consolidated financial statements but will continue to evaluate the new standard in future accounting periods.
