Significant Condensed Consolidated Balance Sheet Components	Significant Condensed Consolidated Balance Sheet Components Property, equipment and software, net includes capitalized software development costs, net of accumulated amortization, of $46.0 million and $49.0 million as of June 30, 2024 and December 31, 2023, respectively. The Company capitalized $6.9 million and $13.3 million of software development costs during the three and six months ended June 30, 2024, respectively, and $9.2 million and $17.8 million during the three and six months ended June 30, 2023, respectively. The Company recorded amortization expense related to capitalized software development costs of $8.3 million and $16.3 million during the three and six months ended June 30, 2024 and $7.0 million and $13.6 million during the three and six months ended June 30, 2023, respectively. During the six months ended June 30, 2024, the Company made a strategic investment of $8.1 million in equity securities of a privately-held company over which the Company does not exercise significant influence. These equity securities do not have a readily determinable fair value and are accounted for under the measurement alternative. Under the measurement alternative, the carrying value of the security is measured at cost less any impairment, and adjusted for changes resulting from observable price changes in orderly transactions for identical or similar securities of the same issuer. An equity security without a readily determinable fair value is considered impaired when the fair value of the Company’s interest is less than the carrying value. Equity investments without readily determinable fair values are included in other assets on the Company’s condensed consolidated balance sheet, and any related gains or losses would be included in other gains (losses), net on the Company’s condensed consolidated statements of operations. Equity investments without readily determinable fair values were $8.1 million as of June 30, 2024, and there were no related changes in carrying amount or impairment during the six months ended June 30, 2024.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Commitments and Other Financial Arrangements —The Company has certain financial commitments and other arrangements including unused letters of credit and commitments under leases. During the three months ended June 30, 2024, the Company entered into an amendment, that has not yet commenced, of an operating lease for office space, with total future lease payments of approximately $5 million that are not yet recorded on the Company’s condensed consolidated balance sheet. This lease amendment is expected to commence in 2025 (upon availability of the office space) with an expected lease term of approximately five years. As of June 30, 2024, there were no other material changes to the Company’s commitments and other financial arrangements as disclosed in Note 8–Commitments and Contingencies in the notes to the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. Litigation and Other Legal Matters —The Company is involved from time to time in litigation, claims, and proceedings. Periodically, the Company evaluates the status of each legal matter and assesses potential financial exposure. If the potential loss from any legal proceeding or litigation is considered probable and the amount can be reasonably estimated, the Company accrues a liability for the estimated loss. Significant judgment is required to determine the probability of a loss and whether the amount of the loss is reasonably estimable. The outcome of any proceeding is not determinable in advance. As a result, the assessment of a potential liability and the amount of accruals recorded are based only on the information available at the time. As additional information becomes available, the Company reassesses the potential liability related to the legal proceeding or litigation, and may revise its estimates. Management is not currently aware of any matters that it expects will have a material effect on the financial position, results of operations, or cash flows of the Company. The Company has not accrued any material potential loss as of June 30, 2024 or December 31, 2023.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Beginning with the three months ended June 30, 2023, the Company’s tax provision for interim periods was determined using a discrete effective tax rate method, as allowed by ASC Topic 740-270, Income Taxes, Interim Reporting . The Company’s tax provision for interim periods was previously determined using an estimated annual effective tax rate which was adjusted for discrete items occurring during the periods presented. The Company determined that since small changes in estimated “ordinary” income would result in significant changes in the estimated annual effective tax rate, the historical method would not provide a reliable estimate for the three and six months ended June 30, 2024. The primary difference between the Company’s effective tax rate and the statutory federal income tax rate is the full valuation allowance established on the Company’s federal, state and foreign deferred tax attributes. As of June 30, 2024 and December 31, 2023, the Company recorded a full valuation allowance against these net deferred tax assets as the Company believes that it is more likely than not that the Company will not be able to fully realize such net deferred tax assets. The Company’s judgment regarding the likelihood of realization of these deferred tax assets could change in future periods, which could result in a material impact in the Company’s income tax provision in the period of change.
