Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated upon consolidation. Discontinued Operations During the fourth quarter of 2024, the Company divested 91% of its European business and Bulgarian subsidiary, Remix, meeting the requirements for reporting Remix as a discontinued operation. Accordingly, Remix’s results, including the loss on divestiture, are presented as discontinued operations in the consolidated statements of income and excluded from continuing operations for all periods presented. Further, the assets and liabilities of Remix have been reclassified as assets and liabilities of discontinued operations in the consolidated balance sheets as of December 31, 2023. In the consolidated statements of cash flows, cash flows attributable to Remix have been segregated and presented separately as net cash flow used in discontinued operating activities and net cash flow used in discontinued investing activities for all periods presented. Unless otherwise noted, amounts and disclosures in these Notes to Consolidated Financial Statements pertain to the Company’s continuing operations. See Note 15, Discontinued Operations , for further details on the transaction. Use of Estimates The preparation of consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the amounts that are reported in the consolidated financial statements and the related disclosures. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include, but are not limited to, the useful lives of property and equipment, allowance for sales returns, breakage on loyalty points and rewards and gift cards, valuation of inventory, stock-based compensation, lease liabilities, and goodwill. Estimates and assumptions about future events and their effects cannot be determined with certainty and therefore require the exercise of significant judgment. New Accounting Pronouncements In November 2024, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses , which expands disclosures about a public entity’s expenses, including inventory, employee compensation, depreciation, intangible asset amortization, selling expenses and other expense categories. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. The Company is currently evaluating the potential impact on its consolidated financial statement disclosures. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures . ASU 2023-09 requires additional quantitative and qualitative income tax disclosures to enable financial statements users to better assess how an entity’s operations and related tax risks and tax planning and operational opportunities affect its tax rate and prospects for future cash flows. For public business entities, ASU 2023-09 is effective for annual periods beginning after December 15, 2024, which will be the fiscal year ending December 31, 2025 for the Company. The Company expects the adoption will result in enhanced income tax disclosures. In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative , to amend certain disclosure and presentation requirements for a variety of topics within the ASC. These amendments align the requirements in the ASC to the removal of certain disclosure requirements set out in Regulation S-X and Regulation S-K, announced by the SEC. The effective date for each amended topic in the ASC is either the date on which the SEC’s removal of the related disclosure requirement from Regulation S-X or Regulation S-K becomes effective, or on June 30, 2027, if the SEC has not removed the requirements by that date. Early adoption is prohibited. The Company does not expect that the application of this standard will have an impact on our consolidated financial statements and disclosures. The Company has assessed all other ASUs issued but not yet adopted and concluded that those not disclosed are not relevant to the Company. Recently Adopted Accounting Pronouncements In November 2023, the FASB issued ASU 2023-07, Improvements to Reportable Segment Disclosures . This new guidance is designed to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024 on a retrospective basis. Early adoption is permitted. The adoption of this guidance enhanced segment reporting disclosures and did not have an impact on the Company’s consolidated financial statements. See the “ Segment Reporting ” section below within this note for additional information. Revenue Recognition Revenue is recognized in accordance with FASB Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“ASC 606”). Under ASC 606, revenue is recognized upon transfer of control of promised goods and services to customers in an amount that reflects the consideration the Company expects to receive for those goods and services. The Company generates the majority of its revenue from its marketplaces, which allows its buyers to browse and purchase resale items for apparel, shoes and accessories on behalf of sellers. The Company recognizes revenue through the following steps: (1) identification of the contract, or contracts, with the customer; (2) identification of the performance obligations in the contract; (3) determination of the transaction price; (4) allocation of the transaction price to the performance obligations in the contract; and (5) recognition of revenue when, or as, it satisfies a performance obligation. Both buyers and sellers may be customers in the Company’s revenue arrangements. Sellers are the primary customer in a consignment arrangement while the buyer is the primary customer in a sale of Company-owned inventory, referred to as product sales. A contract with a customer exists in both cases when the end-customer purchases the goods obligating the Company to deliver the identified performance obligation(s). The Company requires authorization from a credit card or other payment method (such as PayPal), or verification of receipt of payment, before the products are shipped to buyers. The Company generally receives payments from buyers before payments to the sellers are due. Consignment Revenue The Company generates consignment revenue primarily from the sale of secondhand apparel, shoes and accessories on behalf of sellers. The Company retains a percentage of the proceeds received as payment for its consignment service. The Company reports consignment revenue on a net basis as an agent and not the gross amount collected from the buyer. Title to the consigned goods remain with the seller until transferred to the buyer, which occurs subsequent to purchase of the consigned goods and upon expiration of the allotted return period. The Company does not take title of consigned goods at any time except in certain cases where the consignment window expires or returned goods become Company-owned inventory. Additionally, consignment revenue includes bag fees charged to sellers for processing Clean Out Kits. Consignment revenue is generally recognized upon purchase of the consigned good by the buyer as its performance obligation of providing consignment services to the consignor is satisfied at that point. Consignment revenue is also recognized upon purchase of the consigned good for which the consignment window has already expired and the Company has taken title to the consigned good. Consignment revenue is recognized net of seller payouts, discounts, incentives and returns. Revenue from bag fees charged to sellers is recognized when the Clean Out Kit is processed. Sales tax assessed by governmental authorities is excluded from revenue. Product Revenue The Company recognizes product revenue on a gross basis as the Company acts as the principal in the transaction. Online sales and sales to third-party retail partners are generally recognized upon shipment of the purchased good to the buyer. Product revenue is recognized net of discounts, incentives and returns. Sales tax assessed by governmental authorities is excluded from revenue. Shipping Fees The Company charges shipping fees to buyers, which are included in revenue. All outbound shipping costs are accounted for in cost of revenue at the time revenue is recognized. Returns The Company generally has a 14-day return period, which may change from time to time, and recognizes a returns reserve based on historical experience, which is recorded in accrued and other current liabilities within the Company’s consolidated balance sheets and reduction of revenue within the Company’s consolidated statements of operations. Incentives Incentives include website discounts, customer credits and loyalty program rewards issued to sellers and buyers. Incentives are treated as a reduction of consignment revenue and product revenue. Revenue treatment for our loyalty program is discussed further below under Deferred Revenue . Deferred Revenue Deferred revenue consists primarily of product revenue from items purchased but not shipped, and revenue allocated to unredeemed loyalty points. Cash collections for items purchased but not shipped are generally recognized as revenue upon shipment. As of December 31, 2024 and 2023, the Company had $1.9 million in deferred revenue for such items in each period, included in accrued and other current liabilities within the Company’s consolidated balance sheets, and for which revenue was recognized shortly after the period end. Revenue from Loyalty Reward Redemption and Expiration The Company has a customer loyalty program, which allows end-customers to earn and accumulate points with each qualifying purchase. Earned points can be redeemed for reward coupons, such as discounts, free shipping, or waived restocking fee, which can be applied to future purchases or returns. Unredeemed points expire after one year from the date the points were earned. Reward coupons expire six months from the date the reward is claimed. Points earned on purchases are a material right, representing a separate performance obligation. The allocated consideration for the points earned through qualifying purchase transactions is deferred based on the standalone selling price of the points, adjusted for expected breakage in proportion to the pattern of redemption, and recorded within deferred revenue under accrued and other current liabilities within the Company’s consolidated balance sheets. Revenue is recognized for these performance obligations at a point in time when rewards are redeemed by the end customer or expired. As of December 31, 2024 and 2023, the Company had a deferred revenue liability of $1.5 million and $3.1 million, respectively, related to its customer loyalty program, which is included in accrued and other current liabilities within the Company’s consolidated balance sheets. The Company recognized revenue from loyalty reward redemption of $11.5 million and $7.7 million for the years ended December 31, 2024 and 2023, respectively. Beginning October 1, 2024, customers will no longer earn loyalty points and may redeem any accumulated points until expiration but no later than March 31, 2025. As a result, revenue attributable to any remaining performance obligation is expected to be recognized by March 31, 2025. Gift Cards and Site Credits The Company sells ThredUp gift cards on its e-commerce website and may also convert seller payables and site credits to ThredUp gift cards after one year at the discretion of the Company. ThredUp gift cards do not expire or lose value over periods of inactivity. The Company accounts for gift cards by recognizing a gift card liability at the time a gift card is delivered to the customer. As of December 31, 2024 and 2023, $8.5 million and $6.6 million, respectively, of gift card liability was included in accrued and other current liabilities within the Company’s consolidated balance sheets. Revenue from gift cards is generally recognized when the gift cards are redeemed by the customer and amounted to $0.3 million and $2.0 million for the years ended December 31, 2024 and 2023, respectively. The Company recognizes breakage revenue for the portion of gift card values that are not expected to be redeemed. Previously, breakage revenue was estimated when gift card redemption was deemed remote. Beginning in the fourth quarter of 2024, with more historical data available, breakage revenue is estimated based upon historical customer redemption patterns. Judgment is required in determining the appropriate grouping of gift cards for analyzing breakage rates, redemption patterns, and estimating the ultimate value of gift cards not expected to be redeemed. Breakage revenue was $7.2 million and $4.4 million for the years ended December 31, 2024 and 2023, respectively. The Company issues site credits for returns, which can be applied toward future purchases but may not be converted into cash. Site credits may also be converted to ThredUp gift cards after one year at the discretion of the Company. These credits are recognized as revenue when used. As of December 31, 2024 and 2023, $3.8 million and $4.8 million, respectively, of such customer site credits were included in accrued and other current liabilities within the Company’s consolidated balance sheets. Revenue recognized from the redemption of site credits was $43.2 million, and $41.5 million for the years ended December 31, 2024 and 2023, respectively. Segment Reporting The Company operates under one operating segment and one reportable segment as its chief operating decision maker, who is its Chief Executive Officer, reviews financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources and evaluating financial performance. The Company does not have material intra-entity sales or transfers. The key measure of segment profit or loss that the CODM uses to allocate resources and assess performance is the Company’s consolidated loss from continuing operations, as reported in the consolidated statements of operations. Significant expense within operating loss, as well as within loss from continuing operations, include cost of revenue, operations, product and technology, marketing, and sales, general and administrative expenses, which are each separately presented in the consolidated statements of operations. Other segment items within loss from continuing operations include interest expense, other income, net, and provision for income taxes. The CODM manages the business using consolidated expense information, as well as regularly provided budgeted or forecasted expense information. Assets provided to the CODM are consistent with those reported on the consolidated balance sheets. Loss Per Share The Company follows the two-class method when computing loss per common share when shares issued meet the definition of participating securities. The two-class method determines loss per share for each class of common stock and participating securities according to dividends declared or accumulated and participation rights in undistributed earnings. The two-class method requires income available to stockholders for the period to be allocated between common stock and participating securities based upon their respective rights to receive dividends as if all income for the period had been distributed. The rights of the Class A common stock and Class B common stock are identical, other than voting rights. The undistributed earnings are allocated on a proportionate basis and the resulting loss per share attributed to common stockholders will, therefore, be the same for both Class A and Class B common stock on an individual or combined basis. For periods in which the Company reports net losses, diluted loss per share is the same as basic loss per share, because potentially dilutive common shares are not assumed to have been issued if their effect is anti-dilutive. Comprehensive Loss Comprehensive loss is comprised of net loss, foreign currency translation adjustments, and unrealized gains and losses on available-for-sale securities. Cash, Cash Equivalents and Restricted Cash The Company considers all highly liquid investments purchased with a maturity of three months or less to be cash equivalents. Cash and cash equivalents are comprised primarily of domestic and foreign bank accounts, commercial paper, and money market funds. Restricted cash primarily represents letters of credit with financial institutions held as collateral for facility leases and payment processors. Restricted cash is classified non-current if the Company expects that the cash will remain restricted for a period greater than one year. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the Company’s consolidated balance sheets that sum to the total of the same such amounts shown in the Company’s consolidated statements of cash flows: December 31, 2024 2023 (in thousands) Cash and cash equivalents $ 31,851 $ 54,337 Cash and cash equivalents from discontinued operations — 1,747 Restricted cash included in Other current assets 3,690 462 Restricted cash included in Other assets 4,947 4,923 Total cash, cash equivalents, and restricted cash shown in the statement of cash flows $ 40,488 $ 61,469 Marketable Securities The Company invests its excess cash in investment grade, short to intermediate-term, fixed income securities and recognizes the transaction on the trade date. The Company’s marketable securities are classified as available-for-sale in current assets because they represent investments of cash available for current operations. Marketable securities are reported at fair value with unrealized gains and losses reported, net of tax, as a separate component of accumulated other comprehensive gain (loss) until realized. The marketable securities are assessed periodically for impairments. Realized gains or losses and allowance for credit loss, if any, on available-for sale securities are reported in other income (expense), net as incurred. Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash, cash equivalents, marketable securities and accounts receivable. The Company deposits cash at major financial institutions, and at times, such cash may exceed federally insured limits. The credit risk is believed to be minimal due to the financial position of the depository institutions in which those deposits are held. The Company has not experienced any losses on deposits since inception. The Company’s investment policy restricts cash investments to highly liquid, short to intermediate-term, high grade fixed income securities, and as a result, the Company believes its cash equivalents and marketable securities represent minimal credit risk. As of December 31, 2024 and 2023, there were no customers that represented 10% or more of the Company’s accounts receivable balance. There were no customers that individually exceeded 10% of the Company’s revenue for the years ended December 31, 2024 and 2023. Accounts Receivable, Net Accounts receivable consists of amounts due from payment processors and trade customers that do not bear interest. The Company records an allowance for current expected credit losses for estimated losses inherent in its trade accounts receivable portfolio. In establishing the required allowance, management considers historical losses adjusted for current market conditions, the financial condition of the customer, the amount of receivables in dispute, and the current receivables aging and payment patterns. The Company does not have any off-balance sheet credit exposure related to its customers. The allowance for current expected credit losses was not material as of December 31, 2024 and 2023. Inventory Inventories, consisting of merchandise that the Company has purchased and to which the Company holds title, are accounted for using the specific identification method, and are valued at the lower of cost or net realizable value. The cost of inventory is equal to the cost of the merchandise paid to the seller and related inbound shipping costs. Inventory valuation requires the Company to make judgments based on currently available information about the likely method of disposition, such as through sales to individual customers or liquidations, and expected recoverable values of each disposition category. The Company records an inventory write-down based on the age of the inventory and historical experience of expected sell-through. Property and Equipment, Net Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation of property and equipment and amortization of leasehold improvement are computed on a straight-line basis over the estimated useful lives of the related assets, as follows: Asset Category Estimated Useful Life Computers and software Up to 3 years Furniture and fixtures Up to 5 years Machinery and equipment Up to 10 years Leasehold improvements Shorter of economic life or remaining lease term Maintenance and repairs are charged to expense as incurred, and improvements are capitalized. When assets are retired or otherwise disposed of, the cost and accumulated depreciation and amortization are removed from the Company’s consolidated balance sheets and any resulting gain or loss is reflected in the consolidated statements of operations in the period realized. Internal-Use Software The Company capitalizes qualifying proprietary software development costs that are incurred during the application development stage. Capitalization of costs begins when two criteria are met: (i) the preliminary project stage is completed, and (ii) it is probable that the software will be completed and placed in service for its intended use. Capitalization ceases when the software is substantially complete and ready for its intended use including the completion of all significant testing. Costs related to preliminary project activities and post implementation operating activities are expensed as incurred. Amounts capitalized are amortized over two years on a straight-line basis. Impairment of Long-Lived Assets The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset group may not be recoverable. Recoverability of assets held and used is measured by comparison of the carrying amount of an asset to the future undiscounted cash flows expected to be generated from the use of the asset and its eventual disposition. If such review indicates that the carrying amount of the asset group is not recoverable, the carrying amount of such assets is reduced to their fair value. There were no material impairments of long-lived assets for the years ended December 31, 2024 and 2023 related to continuing operations. However, an impairment charge of $9.8 million was recorded for the year ended December 31, 2024 related to discontinued operations. See Note 15, Discontinued Operations, for further details. Goodwill Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. Goodwill is not subject to amortization, but is reviewed for impairment on an annual basis or more frequently if events or changes in circumstances indicate that the carrying value of goodwill may not be recoverable. The Company performed a qualitative assessment during the fourth quarter of 2024 and determined that it is more likely than not that the fair value of its single reporting unit is greater than its carrying value. If it is determined that it is more likely than not that the fair value of the reporting unit is less than its carrying amount or if a qualitative assessment is not performed, then the Company would perform a quantitative goodwill impairment test as required, in which it would use a discounted cash flow approach to estimate the fair value of the reporting unit. If the fair value of the reporting unit is less than the carrying value, then a goodwill impairment amount is recorded for the difference. During the years ended December 31, 2024 and 2023, there were no additions to or impairment of goodwill. As part of the divestiture of Remix, $0.7 million of goodwill was allocated to the disposal group based on the relative fair values of the divested business and the portion retained. Asset Retirement Obligations The Company records asset retirement obligations (“AROs”) for the estimated cost of restoring its automated warehouse facilities to the specific condition required in accordance with the terms of its lease agreement, upon termination of the lease. AROs represent the present value of the expected costs and timing of the related obligations incurred. The ARO assets and liabilities are recorded in property and equipment, net within the machinery and equipment line item and other non-current liabilities, respectively, within the Company’s consolidated balance sheets. The Company records accretion expense, which represents the increase in the ARO, over the remaining estimated duration of the lease including renewal periods that are included in the lease term. Accretion expense is recorded in operations, product and technology expense in the consolidated statements of operations using accretion rates based on credit adjusted risk-free interest rates. Leases Under ASC 842, the Company determines if an arrangement is or contains a lease at inception by assessing whether the arrangement contains an identified asset and whether it has the right to control the identified asset. Lessees are required to classify leases as either finance or operating leases and to record a right-of-use (“ROU”) asset and a lease liability for all leases with a term greater than 12 months regardless of the lease classification. The lease classification will determine whether the lease expense is recognized based on an effective interest rate method or on a straight-line basis over the term of the lease. The Company determines the initial classification and measurement of its ROU assets and lease liabilities at the lease commencement date and thereafter if modified. ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Lease liabilities are recognized at the lease commencement date based on the present value of future lease payments over the lease term. ROU assets are based on the measurement of the lease liability and also include any lease payments made prior to or on lease commencement and exclude lease incentives and initial direct costs incurred, as applicable. As the implicit rate in the Company's leases is generally unknown, the Company uses its incremental borrowing rate based on the information available at the lease commencement date in determining the present value of future lease payments. The Company gives consideration to its existing credit arrangements, term of the lease, total lease payments and adjust for the impacts of collateral, as necessary, when calculating its incremental borrowing rates. The lease terms may include options to extend or terminate the lease when it is reasonably certain the Company will exercise any such options. Lease costs for the Company's operating leases are recognized on a straight-line basis within operating expenses over the lease term. The Company has elected to not separate lease and non-lease components for real estate leases and, as a result, accounts for lease and non-lease components as one component. The Company has also elected to not apply the recognition requirement to any leases within its existing classes of assets with a term of 12 months or less. For these leases, lease payments are recognized on a straight-line basis over the lease term and variable payments in the period in which the obligation is incurred. Seller Payable Seller payable includes amounts owed to sellers upon the purchase of sellers’ goods by the Company or by buyers. Amounts are initially provided as a credit to sellers. These credits may be applied towards purchases from the Company, converted to third-party retailer or ThredUp gift cards or redeemed for cash. As of December 31, 2024 and 2023, there was $15.1 million and $20.8 million, respectively, of seller payable within the Company’s consolidated balance sheets. Revenue recognized from the redemption of seller credits was $22.9 million and $16.5 million for the years ended December 31, 2024 and 2023, respectively. Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income on the years in which those temporary differences are expected to be recovered and settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company records interest and penalties related to unrecognized tax benefits in income tax expense. Cost of Revenue Cost of consignment revenue consists of outbound shipping, outbound labor and packaging costs. Cost of product revenue mainly consists of the inventory cost, inbound shipping related to the sold merchandise, outbound shipping, outbound labor, packaging costs and inventory write-downs. The classification of expenses varies across the retail industry. Accordingly, our cost of revenue may not be comparable to those of other companies in the retail industry. Operations, Product and Technology Operations, product and technology expenses consist primarily of distribution center operating costs and product and technology expenses. Distribution center operating costs include personnel costs, distribution center rent, maintenance and equipment depreciation as well as inbound shipping costs, other than those capitalized in inventory. Product and technology costs include personnel costs for the design and development of product and the related technology that is used to operate the distribution centers, merchandise science, website development and related expenses for these departments. Operations, product and technology expenses also include an allocation of corporate facilities and information technology costs including equipment, depreciation and rent. Research and development costs from continuing operations related to our technology were approximately $31.3 million and $32.6 million, during the years ended December 31, 2024 and 2023, respectively. Marketing Marketing costs consist primarily of advertising, public relations expenditures and personnel costs for employees engaged in marketing. Marketing costs also include an allocation of corporate facilities and information technology costs including equipment, depreciation and rent. Advertising and other promotional costs from continuing operations included in marketing within the Company’s consolidated statements of operations are expensed as incurred and were approximately $41.5 million and $38.8 millio

As such, the unrealized gains or losses related to the Company’s cash equivalents and marketable securities were not material. For the Company’s marketable securities, which were all classified as available-for-sale, the Company utilizes third-party pricing services to obtain fair value. Third-party pricing methodologies incorporate bond terms and conditions, current performance data, proprietary pricing models, real-time quotes from contributing dealers, trade prices and other market data. The Company determined that the declines in the fair value of its marketable securities were not driven by credit-related factors. During the years ended December 31, 2024 and 2023, the Company did not recognize any losses on its marketable securities due to credit-related factors. As of December 31, 2024, the Company’s money market funds, were valued using Level 1 inputs because they are valued using quoted prices in active markets. The Company’s commercial paper, U.S. treasury securities, and U.S. government agency bonds were valued using Level 2 inputs because they are valued using quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. There were no transfers into or out of Level 3 during the year ended December 31, 2024. As of December 31, 2024, of the $12.3 million carrying amount of marketable securities, all had a contractual maturity date of less than one year. Fair Value Measurements - Nonrecurring Basis The Company measures the fair value of certain assets on a nonrecurring basis when events or changes in circumstances indicate that the carrying value of the asset or asset group may not be recoverable. In the third quarter of 2024, the Company performed impairment assessments of its long-lived assets and goodwill following the decision to exit the European market and a decline in market capitalization, recognizing a $9.8 million impairment of long-lived assets. In the fourth quarter of 2024, as part of the Remix divestiture, the Company recognized a convertible notes receivable of $350,000 and a retained equity interest of $530,000. These assets are classified as Level 3 within the fair value hierarchy. See Note 15, Discontinued Operations , for a further discussion on the transaction, impairment assessments, and related fair value measurements.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	Goodwill Goodwill is primarily attributable to the planned growth in the combined business after the acquisition of Remix Global EAD (“Remix”). Goodwill was $10.7 million and $11.2 million as of December 31, 2024 and 2023, respectively. The change in goodwill during the year ended December 31, 2024 was due to an allocation of $0.7 million of goodwill to the disposal group as part of the divestiture of Remix, with the remaining immaterial change resulting from foreign currency translation adjustment. Goodwill was allocated to the disposal group based on the relative fair values of the divested business and the portion retained. In the third quarter of 2024, the Company performed a quantitative goodwill impairment assessment as a result of its decision to exit the European market and the decline in its market capitalization. There was no impairment recognized on goodwill as its fair value exceeded its carrying amount as of the valuation date. In the fourth quarter, the Company conducted its annual goodwill impairment test, including a qualitative assessment. Based on this evaluation, no indicators of impairment were identified. Accordingly, the Company determined that it is more likely than not that the fair value of the Company’s single reporting unit exceeds its carrying value.

Long-Term Debt

Long-Term Debt	12 Months Ended

Debt Disclosure [Abstract]
Long-Term Debt	Long-Term Debt In February 2019, the Company entered into a loan and security agreement (“Term Loan”) with Western Alliance Bank for an aggregate amount of up to $40.0 million and incurred an immaterial amount of debt issuance costs, which were recorded on the Company’s consolidated balance sheets and are being amortized over the life of the Term Loan using the effective-interest method. The Term Loan was subsequently amended several times, with the most recent amendment taking place in December 2023. As amended, the Term Loan matures on July 14, 2027 and provides for an aggregate borrowing amount of up to $48.8 million, of which $22.5 million remains available and is designated for the purchase of certain equipment. The Term Loan bears interest at the prime rate published in the Wall Street Journal plus a margin of 1.25%, with a floor of 4.75%. The Term Loan requires the Company to comply with certain financial covenants, including, among other things, liquidity requirements, performance metrics, and a debt service coverage ratio. The Term Loan also contains affirmative and negative covenants customary for financings of this type, including, among other things, limitations or prohibitions on repurchasing common shares, declaring and paying dividends and other distributions, redeeming and repurchasing certain other indebtedness, loans and investments, additional indebtedness, liens, mergers, asset sales and transactions with affiliates. In addition, the Term Loan contains customary events of default. As of December 31, 2024, the Company was in compliance with its debt covenants under the Term Loan. The Term Loan is payable in consecutive monthly installments. Interest is due monthly on amounts outstanding under the Term Loan. The Company is also permitted to make voluntary prepayments without penalty or premium at any time. As of December 31, 2024 and 2023, the effective interest rate for borrowings under the Term Loan was 9.71% and 10.73%, respectively. During the years ended December 31, 2024 and 2023, the Company did not make any borrowings under the Term Loan and repaid $4.0 million each year on amounts outstanding under the Term Loan. As of December 31, 2024 and 2023, the amount outstanding under the Term Loan was $22.3 million and $26.3 million, respectively. During the years ended December 31, 2024 and 2023, the Company incurred interest costs of $2.5 million and $2.9 million, respectively, related to the Term Loan. There was no capitalized interest for the year ended December 31, 2024, and $0.6 million was capitalized as part of an asset for the year ended December 31, 2023.

Stock-Based Compensation

Stock-Based Compensation	12 Months Ended

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation 2010 Stock Incentive Plan In 2010, the Company adopted the Second Amended and Restated 2010 Stock Plan (“2010 Plan”), and amended the 2010 Plan in 2011. The 2010 Plan provides for the grant of stock awards to employees, consultants and directors of the Company. Options granted under the 2010 Plan may either be Incentive Stock Options (“ISOs”) or Nonstatutory Stock Options (“NSOs”). ISOs may be granted to Company employees only, while stock awards other than ISOs may be granted to employees, directors and consultants. In 2020, the board of directors authorized an additional 6.5 million shares for the 2010 Plan. In 2021, the board of directors authorized an additional 1.0 million shares for the 2010 Plan. Stock awards under the 2010 Plan may be granted with terms of up to 10 years and at prices determined by the board of directors, provided, however, that (i) the exercise price of an ISO or NSO shall not be less than 100% of the estimated fair value of the shares on the date of the grant, and (ii) the exercise price of an ISO granted to a 10% or more stockholder shall not be less than 110% of the estimated fair value of the shares on the grant date. The options generally vest over a four-year period. For certain options, vesting accelerates upon the occurrence of specified events, such as a change of control. 2021 Stock Option and Incentive Plan In February 2021, in connection with the IPO, the Company’s board of directors adopted the 2021 Stock Option and Incentive Plan (“2021 Plan”) to replace the 2010 Plan, which was subsequently approved by the Company’s stockholders in March 2021. The 2021 Plan became effective on March 24, 2021. Stock option activity under the 2010 Plan, as amended is as follows: Number of Options Outstanding Weighted-Average Exercise Price Per Share Weighted-Average Remaining Contractual Life Aggregate Intrinsic Value (in thousands) (in thousands) Outstanding as of December 31, 2023 16,247 $ 1.99 4.14 years $ 5,861 Granted — $ — Exercised (1,013) $ 0.90 Forfeited or expired (1,492) $ 1.06 Outstanding as of December 31, 2024 13,742 $ 2.16 3.61 years $ 5,300 Exercisable as of December 31, 2024 13,277 $ 2.17 3.54 years $ 5,300 The aggregated intrinsic value represents the difference between the exercise price and the fair value of common stock. The aggregate intrinsic value of all options exercised was $0.4 million and $1.6 million during the years ended December 31, 2024 and 2023, respectively. As of December 31, 2024, the total unrecognized compensation cost related to all nonvested stock options was not material. Each of these inputs is subjective and generally requires significant judgment: • Fair Value of Common Stock — Historically, for all periods prior to the IPO in March 2021, the fair value of the shares of common stock has historically been determined by the Company’s board of directors as there was no public market for the common stock. The board of directors determined the fair value of our common stock by considering a number of objective and subjective factors, including: the valuation of comparable companies, sales of preferred stock to unrelated third parties, our operating and financial performance, the lack of liquidity of common stock and general and industry specific economic outlook, amongst other factors. After the completion of the IPO in March 2021, the fair value of each share of underlying common stock is based on the closing price of the Company’s common stock as reported on the date of grant on the Nasdaq Global Select Market. • Expected Term — The expected term represents the period that the Company’s stock options are expected to be outstanding and is determined using the simplified method (based on the mid-point between the vesting date and the end of the contractual term) as the Company has concluded that its stock option exercise history does not provide a reasonable basis upon which to estimate expected term. • Volatility — Because the Company does not have sufficient trading history for its common stock, the expected volatility was estimated based on the average volatility for comparable publicly-traded companies, over a period equal to the expected term of the stock option grants. • Risk-Free Rate — The risk-free rate assumption is based on the U.S. Treasury zero coupon issues in effect at the time of grant for periods corresponding with the expected term of the option. • Dividends — The Company has never paid dividends on its common stock and does not anticipate paying dividends on common stock. Therefore, the Company uses an expected dividend yield of zero. Employee Stock Purchase Plan In February 2021, the Company’s board of directors adopted the Employee Stock Purchase Plan (“ESPP”), which was subsequently approved by stockholders in March 2021. The ESPP became effective on March 24, 2021, and the first offering period began on March 25, 2021. Under the terms of the ESPP, rights to purchase common shares may be granted to eligible qualified employees subject to certain restrictions. The ESPP enables the Company’s eligible employees, through payroll withholding, to purchase a limited number of common shares at 85% of the fair market value of a common share either at the beginning of that offering period or on the applicable exercise date, whichever is less. Purchases are made on a semi-annual basis. During the years ended December 31, 2024 and 2023, compensation expense related to ESPP was not material. Restricted Stock Units The Company issues service-based RSUs to employees. The RSUs automatically convert to shares of the Company’s Class A common stock on a one-for-one basis as the awards vest. RSUs were granted to newly hired employees typically vest in equal quarterly installments over 3 or 4 years, provided that the initial vest occurs after a 1-year cliff. During 2023, the Company modified the vesting schedule of substantially all RSUs outstanding as of December 31, 2022 from 4 years to 3 years and recognized compensation expense of $2.4 million related to the acceleration of the vesting schedule. Such grants commence vesting as of the nearest scheduled quarterly vesting date from the date of grant. The RSUs are measured at grant date fair value, at the market price of the Company’s common stock on the grant date.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The components of loss from continuing operations before provision for income taxes were $40.0 million and $52.3 million during the years ended December 31, 2024 and 2023, respectively. The Company had no federal provision for income taxes as the Company has incurred operating losses since inception. The Company’s state tax provision, which was current, was not material for the years ended December 31, 2024 and 2023. The Company’s effective tax rate, as a percentage of pretax income from continuing operations, differs from the statutory federal rate primarily due to the valuation allowance that the Company records on its deferred tax assets, as management believes it is more likely than not that the deferred tax assets will not be fully realized. The reconciliation between the provision for income taxes at the statutory rate and the provision for income taxes at the effective tax rate from continuing operations is as follows: Year Ended December 31, 2024 2023 (in thousands) Tax expense at U.S. statutory rate $ (8,394) $ (10,727) Increase (decrease) in tax resulting from: State taxes, net of federal effect 23 17 Non-deductible and other expenses 860 921 Stock-based compensation 2,540 4,471 Change in valuation allowance 5,000 5,337 Total $ 29 $ 19 The significant categories of temporary differences that gave rise to deferred tax assets and liabilities were as follows: December 31, 2024 2023 (in thousands) Deferred tax assets: Accruals and reserves $ 2,741 $ 2,639 Inventory and deferred revenue 115 91 Capitalized research and development costs 14,100 11,112 Stock-based compensation 2,238 1,563 Capital losses 21,746 — Intangibles 393 76 Other 1,303 1,598 Net operating loss carryforwards 87,701 92,822 Gross deferred tax assets 130,337 109,901 Less: valuation allowance (120,612) (98,404) Total deferred tax assets 9,725 11,497 Deferred tax liabilities: Fixed assets 9,723 11,222 Other 2 275 Total deferred tax liabilities 9,725 11,497 Total net deferred tax assets $ — $ — Deferred income taxes reflect the net tax effects of (a) temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, and (b) operating losses and tax credit carryforwards. Net deferred tax assets consist primarily of net operating loss carryforwards of approximately $87.7 million and $92.8 million as of December 31, 2024 and 2023, respectively, related to U.S. federal and state taxes. Net deferred tax assets also include capital loss carryforwards of $21.7 million related to U.S. federal and state taxes that were generated in the year ended December 31, 2024 as a result of the Remix divestiture transaction on November 30, 2024. See Note 15, Discontinued Operations , for further details. A valuation allowance is provided when it is more likely than not that the deferred tax assets will not be realized. As of December 31, 2024 and 2023, the Company held valuation allowances against its deferred tax assets due to the uncertainty of realizing future benefits from its net operating loss carryforwards, capital loss carryforwards, and other deferred tax assets. The valuation allowance increased by $22.2 million and $6.5 million during the years ended December 31, 2024 and 2023, respectively. U.S. federal and state net operating loss carryforwards of $342.3 million and $271.4 million, respectively, for income tax purposes are available to offset future taxable income as of December 31, 2024. $263.3 million of the U.S. federal net operating losses can be carried forward indefinitely and are available to offset 80% of future taxable income. If not used, these federal carryforwards will begin to expire in varying amounts beginning in 2034. The Tax Reform Act of 1986 and similar California legislation impose substantial restrictions on the utilization of net operating losses and tax credit carryforwards in the event that there is a change in ownership as provided by Section 382 and Section 383 of the Internal Revenue Code and similar state provisions. Such a limitation could result in the limitation and/or expiration of the net operating loss carryforwards and tax credits before utilization, which could result in increased future tax liabilities when the Company becomes taxable for federal or state purposes. While the Company has experienced an ownership change since its inception, an immaterial amount of net operating losses or tax credits has been limited as of December 31, 2024. The Company recognizes the benefits of income tax positions only if the positions are more likely than not of being sustained. As of December 31, 2024 and 2023, the amount of gross unrecognized tax benefits related to continuing operations was $1.3 million and $1.0 million, respectively. All of the unrecognized tax benefits, if recognized, would not impact the Company’s effective income tax rate. A reconciliation of gross unrecognized tax benefits from continuing operations is as follows: Year Ended December 31, 2024 2023 (in thousands) Balance at the beginning of the period $ 987 $ — Increases related to prior year tax positions — 319 Increases related to current year tax positions 285 668 Balance at the end of the period $ 1,272 $ 987 The Company’s tax years 2010 through current will remain open for examination by the federal and state authorities for three and four years, respectively, from the date of utilization of any net operating loss or tax credit carryforward. The Company is not currently under examination by income tax authorities in federal, state or other jurisdictions.

Discontinued Operations

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations Divestiture On November 30, 2024, the Company exited the European market by completing the sale of its European subsidiary, Remix, to Remix’s management (the “Transaction”). The divestiture qualified for held-for-sale classification on November 30, 2024 and represented a strategic shift with a major effect on the Company’s operations and financial results. Following the divestiture, the Company will not have any significant continuing involvement in the operations of Remix. As a result, Remix met the criteria for reporting as a discontinued operation on the same date. Upon the closing of the Transaction, the Company retained a 9% equity interest in Remix US Holdings, Inc., the parent company of Remix, with a fair value of $530,000, and received cash proceeds of EUR 1.00. The minority investment does not provide the Company with significant influence over Remix and will be accounted for under the cost method. The Company has not elected the fair value option for this investment. The investment will be assessed for impairment at each reporting period or if indicators of impairment arise. In connection with the Transaction, Remix issued an unsecured convertible promissory note (the “Convertible Note”) to the Company as consideration for the Transaction. The Convertible Note, reflecting the Company’s investment since acquiring Remix for various purposes, including infrastructure, technology, and personnel development, had a fair value of $350,000. The Convertible Note has an aggregate principal amount of EUR 61.6 million and bears interest at 125 basis points plus the greater of the 12-month EURIBOR rate or zero, determined annually on November 30. The Convertible Note does not have a fixed maturity date, and the Company does not anticipate full repayment, with both the timing and amount of any potential repayment remaining uncertain. Through its conversion feature, the Convertible Note ensures the Company’s ownership interest in Remix remains at 9% and cannot exceed this level, regardless of potential future dilutive actions. Consequently, the discount, representing the difference between the aggregated principal amount and fair value, is not subject to amortization, and accrued interest will be offset by a credit reserve adjustment and immediately written off in future periods, resulting no net impact to the Company’s financial statements. The fair value of retained equity interest was estimated using a combination of a market approach, which incorporated valuation multiples of comparable public companies and transactions, and an income approach based on projected discounted cash flows (the “DCF” model). The significant assumptions used included estimates of future revenues and operating expenses, long-term growth rates, working capital requirements, discount rates, and discounts for lack of marketability and control, which are considered unobservable inputs and are classified as Level 3 within the fair value hierarchy. Estimating the fair value of a business was a subjective process that involved assumptions market participants would use in determining fair value, along with other estimates and judgments, particularly related to future cash flows, which are inherently uncertain. The Company utilized a probability-weighted approach to determine the transaction-date fair value of the Convertible Note by analyzing all possible repayment scenarios, the estimated cash flows that the Company would receive under each scenario, and the likelihood of each scenario occurring. As of December 31, 2024, the 9% retained equity interest in Remix US Holdings, Inc., valued at $530,000, and the Convertible Note, valued at $350,000, were recorded in other assets within the consolidated balance sheets. As a result of the Transaction, the Company derecognized net assets of $7.6 million, a previously recognized foreign currency translation adjustment of $3.6 million, and incurred transaction costs of $1.0 million, resulting in a loss of $11.3 million, recorded in loss from discontinued operations, net of tax Remix’s financial results are presented as loss from discontinued operations, net of tax in the consolidated statements of operations. For fiscal 2024, these results include the period from the beginning of the year through the date of the Transaction. The following table presents the major components of Remix’s financial results for the periods presented: Year Ended December 31, 2024 2023 (in thousands) Total revenue $ 47,317 $ 63,518 Total cost of revenue 33,937 48,181 Operating expenses 39,077 34,176 Other income (expense), net 44 (53) Loss on Remix divestiture (11,334) — Loss from discontinued operations $ (36,987) $ (18,892) The following table represents the aggregated carrying amounts of assets and liabilities classes classified as discontinued operations in the consolidated balance sheets for the period presented: December 31, 2023 (in thousands) Assets: Inventory $ 12,863 Other current assets 4,766 Current assets of discontinued operations 17,629 Operating lease right-of-use assets 14,021 Property and equipment, net 9,850 Intangible assets 8,156 Other assets 1,498 Non-current assets of discontinued operations 33,525 Total assets of discontinued operations $ 51,154 Liabilities: Accounts payable $ 5,626 Accrued and other current liabilities 8,522 Current liabilities of discontinued operations 14,148 Operating lease liabilities, non-current 12,800 Other non-current liabilities 628 Non-current liabilities of discontinued operations 13,428 Total liabilities of discontinued operations $ 27,576 Impairments In the third quarter of 2024, the Company announced its decision to exit the European market and that it had initiated a strategic review of its Remix business. However, the Company did not classify Remix as held for sale during this period, as the necessary criteria were not met due to the required approval not being obtained. The decision to exit the European market, coupled with the decline in the Company’s market capitalization, were identified as qualitative indicators of potential impairment of long-lived assets and goodwill. Consequently, the Company performed long-lived assets and goodwill impairment assessments during the third quarter of 2024 and recognized an impairment of long-lived assets of $9.8 million, of which $5.6 million related to certain property and equipment and $4.2 million related to intangible assets, recorded within loss from discontinued operations, net of tax In conducting the long-lived assets and goodwill impairment assessments in the third quarter of 2024, the Company determined fair values using a combination of a market approach, which incorporated valuation multiples of comparable public companies and transactions, and an income approach based on projected DCF model. The significant assumptions used in the DCF model included estimates of future revenues and operating expenses, long-term growth rates, working capital requirements, and discount rates, which are considered unobservable inputs and are classified as Level 3 within the fair value hierarchy. Estimating the fair value of a business was a subjective process that involved assumptions market participants would use in determining fair value, along with other estimates and judgments, particularly related to future cash flows, which are inherently uncertain.

Significant Accounting Polici_2

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2024
Accounting Policies [Abstract]
Basis of Presentation	The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated upon consolidation.
Discontinued Operations	During the fourth quarter of 2024, the Company divested 91% of its European business and Bulgarian subsidiary, Remix, meeting the requirements for reporting Remix as a discontinued operation. Accordingly, Remix’s results, including the loss on divestiture, are presented as discontinued operations in the consolidated statements of income and excluded from continuing operations for all periods presented. Further, the assets and liabilities of Remix have been reclassified as assets and liabilities of discontinued operations in the consolidated balance sheets as of December 31, 2023. In the consolidated statements of cash flows, cash flows attributable to Remix have been segregated and presented separately as net cash flow used in discontinued operating activities and net cash flow used in discontinued investing activities for all periods presented. Unless otherwise noted, amounts and disclosures in these Notes to Consolidated Financial Statements pertain to the Company’s continuing operations.
Use of Estimates	The preparation of consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the amounts that are reported in the consolidated financial statements and the related disclosures. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include, but are not limited to, the useful lives of property and equipment, allowance for sales returns, breakage on loyalty points and rewards and gift cards, valuation of inventory, stock-based compensation, lease liabilities, and goodwill. Estimates and assumptions about future events and their effects cannot be determined with certainty and therefore require the exercise of significant judgment.
New Accounting Pronouncements and Recently Adopted Accounting Pronouncements	In November 2024, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses , which expands disclosures about a public entity’s expenses, including inventory, employee compensation, depreciation, intangible asset amortization, selling expenses and other expense categories. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. The Company is currently evaluating the potential impact on its consolidated financial statement disclosures. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures . ASU 2023-09 requires additional quantitative and qualitative income tax disclosures to enable financial statements users to better assess how an entity’s operations and related tax risks and tax planning and operational opportunities affect its tax rate and prospects for future cash flows. For public business entities, ASU 2023-09 is effective for annual periods beginning after December 15, 2024, which will be the fiscal year ending December 31, 2025 for the Company. The Company expects the adoption will result in enhanced income tax disclosures. In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative , to amend certain disclosure and presentation requirements for a variety of topics within the ASC. These amendments align the requirements in the ASC to the removal of certain disclosure requirements set out in Regulation S-X and Regulation S-K, announced by the SEC. The effective date for each amended topic in the ASC is either the date on which the SEC’s removal of the related disclosure requirement from Regulation S-X or Regulation S-K becomes effective, or on June 30, 2027, if the SEC has not removed the requirements by that date. Early adoption is prohibited. The Company does not expect that the application of this standard will have an impact on our consolidated financial statements and disclosures. The Company has assessed all other ASUs issued but not yet adopted and concluded that those not disclosed are not relevant to the Company. Recently Adopted Accounting Pronouncements In November 2023, the FASB issued ASU 2023-07, Improvements to Reportable Segment Disclosures
Revenue Recognition, Gift Cards and Site Credits	Revenue is recognized in accordance with FASB Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“ASC 606”). Under ASC 606, revenue is recognized upon transfer of control of promised goods and services to customers in an amount that reflects the consideration the Company expects to receive for those goods and services. The Company generates the majority of its revenue from its marketplaces, which allows its buyers to browse and purchase resale items for apparel, shoes and accessories on behalf of sellers. The Company recognizes revenue through the following steps: (1) identification of the contract, or contracts, with the customer; (2) identification of the performance obligations in the contract; (3) determination of the transaction price; (4) allocation of the transaction price to the performance obligations in the contract; and (5) recognition of revenue when, or as, it satisfies a performance obligation. Both buyers and sellers may be customers in the Company’s revenue arrangements. Sellers are the primary customer in a consignment arrangement while the buyer is the primary customer in a sale of Company-owned inventory, referred to as product sales. A contract with a customer exists in both cases when the end-customer purchases the goods obligating the Company to deliver the identified performance obligation(s). The Company requires authorization from a credit card or other payment method (such as PayPal), or verification of receipt of payment, before the products are shipped to buyers. The Company generally receives payments from buyers before payments to the sellers are due. Consignment Revenue The Company generates consignment revenue primarily from the sale of secondhand apparel, shoes and accessories on behalf of sellers. The Company retains a percentage of the proceeds received as payment for its consignment service. The Company reports consignment revenue on a net basis as an agent and not the gross amount collected from the buyer. Title to the consigned goods remain with the seller until transferred to the buyer, which occurs subsequent to purchase of the consigned goods and upon expiration of the allotted return period. The Company does not take title of consigned goods at any time except in certain cases where the consignment window expires or returned goods become Company-owned inventory. Additionally, consignment revenue includes bag fees charged to sellers for processing Clean Out Kits. Consignment revenue is generally recognized upon purchase of the consigned good by the buyer as its performance obligation of providing consignment services to the consignor is satisfied at that point. Consignment revenue is also recognized upon purchase of the consigned good for which the consignment window has already expired and the Company has taken title to the consigned good. Consignment revenue is recognized net of seller payouts, discounts, incentives and returns. Revenue from bag fees charged to sellers is recognized when the Clean Out Kit is processed. Sales tax assessed by governmental authorities is excluded from revenue. Product Revenue The Company recognizes product revenue on a gross basis as the Company acts as the principal in the transaction. Online sales and sales to third-party retail partners are generally recognized upon shipment of the purchased good to the buyer. Product revenue is recognized net of discounts, incentives and returns. Sales tax assessed by governmental authorities is excluded from revenue. Shipping Fees The Company charges shipping fees to buyers, which are included in revenue. All outbound shipping costs are accounted for in cost of revenue at the time revenue is recognized. Returns The Company generally has a 14-day return period, which may change from time to time, and recognizes a returns reserve based on historical experience, which is recorded in accrued and other current liabilities within the Company’s consolidated balance sheets and reduction of revenue within the Company’s consolidated statements of operations. Incentives Incentives include website discounts, customer credits and loyalty program rewards issued to sellers and buyers. Incentives are treated as a reduction of consignment revenue and product revenue. Revenue treatment for our loyalty program is discussed further below under Deferred Revenue . Deferred Revenue Deferred revenue consists primarily of product revenue from items purchased but not shipped, and revenue allocated to unredeemed loyalty points. Cash collections for items purchased but not shipped are generally recognized as revenue upon shipment. As of December 31, 2024 and 2023, the Company had $1.9 million in deferred revenue for such items in each period, included in accrued and other current liabilities within the Company’s consolidated balance sheets, and for which revenue was recognized shortly after the period end. Revenue from Loyalty Reward Redemption and Expiration The Company has a customer loyalty program, which allows end-customers to earn and accumulate points with each qualifying purchase. Earned points can be redeemed for reward coupons, such as discounts, free shipping, or waived restocking fee, which can be applied to future purchases or returns. Unredeemed points expire after one year from the date the points were earned. Reward coupons expire six months from the date the reward is claimed. Points earned on purchases are a material right, representing a separate performance obligation. The allocated consideration for the points earned through qualifying purchase transactions is deferred based on the standalone selling price of the points, adjusted for expected breakage in proportion to the pattern of redemption, and recorded within deferred revenue under accrued and other current liabilities within the Company’s consolidated balance sheets. Revenue is recognized for these performance obligations at a point in time when rewards are redeemed by the end customer or expired. As of December 31, 2024 and 2023, the Company had a deferred revenue liability of $1.5 million and $3.1 million, respectively, related to its customer loyalty program, which is included in accrued and other current liabilities within the Company’s consolidated balance sheets. The Company recognized revenue from loyalty reward redemption of $11.5 million and $7.7 million for the years ended December 31, 2024 and 2023, respectively. Beginning October 1, 2024, customers will no longer earn loyalty points and may redeem any accumulated points until expiration but no later than March 31, 2025. As a result, revenue attributable to any remaining performance obligation is expected to be recognized by March 31, 2025. Gift Cards and Site Credits The Company sells ThredUp gift cards on its e-commerce website and may also convert seller payables and site credits to ThredUp gift cards after one year at the discretion of the Company. ThredUp gift cards do not expire or lose value over periods of inactivity. The Company accounts for gift cards by recognizing a gift card liability at the time a gift card is delivered to the customer. As of December 31, 2024 and 2023, $8.5 million and $6.6 million, respectively, of gift card liability was included in accrued and other current liabilities within the Company’s consolidated balance sheets. Revenue from gift cards is generally recognized when the gift cards are redeemed by the customer and amounted to $0.3 million and $2.0 million for the years ended December 31, 2024 and 2023, respectively. The Company recognizes breakage revenue for the portion of gift card values that are not expected to be redeemed. Previously, breakage revenue was estimated when gift card redemption was deemed remote. Beginning in the fourth quarter of 2024, with more historical data available, breakage revenue is estimated based upon historical customer redemption patterns. Judgment is required in determining the appropriate grouping of gift cards for analyzing breakage rates, redemption patterns, and estimating the ultimate value of gift cards not expected to be redeemed. Breakage revenue was $7.2 million and $4.4 million for the years ended December 31, 2024 and 2023, respectively. The Company issues site credits for returns, which can be applied toward future purchases but may not be converted into cash. Site credits may also be converted to ThredUp gift cards after one year at the discretion of the Company. These credits are recognized as revenue when used. As of December 31, 2024 and 2023, $3.8 million and $4.8 million, respectively, of such customer site credits were included in accrued and other current liabilities within the Company’s consolidated balance sheets. Revenue recognized from the redemption of site credits was $43.2 million, and $41.5 million for the years ended December 31, 2024 and 2023, respectively.
Segment Reporting	The Company operates under one operating segment and one reportable segment as its chief operating decision maker, who is its Chief Executive Officer, reviews financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources and evaluating financial performance. The Company does not have material intra-entity sales or transfers. The key measure of segment profit or loss that the CODM uses to allocate resources and assess performance is the Company’s consolidated loss from continuing operations, as reported in the consolidated statements of operations.
Loss Per Share	The Company follows the two-class method when computing loss per common share when shares issued meet the definition of participating securities. The two-class method determines loss per share for each class of common stock and participating securities according to dividends declared or accumulated and participation rights in undistributed earnings. The two-class method requires income available to stockholders for the period to be allocated between common stock and participating securities based upon their respective rights to receive dividends as if all income for the period had been distributed. The rights of the Class A common stock and Class B common stock are identical, other than voting rights. The undistributed earnings are allocated on a proportionate basis and the resulting loss per share attributed to common stockholders will, therefore, be the same for both Class A and Class B common stock on an individual or combined basis. For periods in which the Company reports net losses, diluted loss per share is the same as basic loss per share, because potentially dilutive common shares are not assumed to have been issued if their effect is anti-dilutive.
Comprehensive Loss	Comprehensive loss is comprised of net loss, foreign currency translation adjustments, and unrealized gains and losses on available-for-sale securities.
Cash, Cash Equivalents, and Restricted Cash	The Company considers all highly liquid investments purchased with a maturity of three months or less to be cash equivalents. Cash and cash equivalents are comprised primarily of domestic and foreign bank accounts, commercial paper, and money market funds. Restricted cash primarily represents letters of credit with financial institutions held as collateral for facility leases and payment processors. Restricted cash is classified non-current if the Company expects that the cash will remain restricted for a period greater than one year.
Marketable Securities	The Company invests its excess cash in investment grade, short to intermediate-term, fixed income securities and recognizes the transaction on the trade date. The Company’s marketable securities are classified as available-for-sale in current assets because they represent investments of cash available for current operations. Marketable securities are reported at fair value with unrealized gains and losses reported, net of tax, as a separate component of accumulated other comprehensive gain (loss) until realized. The marketable securities are assessed periodically for impairments. Realized gains or losses and allowance for credit loss, if any, on available-for sale securities are reported in other income (expense), net as incurred.
Concentrations of Credit Risk	Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash, cash equivalents, marketable securities and accounts receivable. The Company deposits cash at major financial institutions, and at times, such cash may exceed federally insured limits. The credit risk is believed to be minimal due to the financial position of the depository institutions in which those deposits are held. The Company has not experienced any losses on deposits since inception. The Company’s investment policy restricts cash investments to highly liquid, short to intermediate-term, high grade fixed income securities, and as a result, the Company believes its cash equivalents and marketable securities represent minimal credit risk.
Accounts Receivable, Net	Accounts receivable consists of amounts due from payment processors and trade customers that do not bear interest. The Company records an allowance for current expected credit losses for estimated losses inherent in its trade accounts receivable portfolio. In establishing the required allowance, management considers historical losses adjusted for current market conditions, the financial condition of the customer, the amount of receivables in dispute, and the current receivables aging and payment patterns. The Company does not have any off-balance sheet credit exposure related to its customers.
Inventory	Inventories, consisting of merchandise that the Company has purchased and to which the Company holds title, are accounted for using the specific identification method, and are valued at the lower of cost or net realizable value. The cost of inventory is equal to the cost of the merchandise paid to the seller and related inbound shipping costs. Inventory valuation requires the Company to make judgments based on currently available information about the likely method of disposition, such as through sales to individual customers or liquidations, and expected recoverable values of each disposition category. The Company records an inventory write-down based on the age of the inventory and historical experience of expected sell-through.
Property and Equipment, Net	Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation of property and equipment and amortization of leasehold improvement are computed on a straight-line basis over the estimated useful lives of the related assets, as follows: Asset Category Estimated Useful Life Computers and software Up to 3 years Furniture and fixtures Up to 5 years Machinery and equipment Up to 10 years Leasehold improvements Shorter of economic life or remaining lease term Maintenance and repairs are charged to expense as incurred, and improvements are capitalized. When assets are retired or otherwise disposed of, the cost and accumulated depreciation and amortization are removed from the Company’s consolidated balance sheets and any resulting gain or loss is reflected in the consolidated statements of operations in the period realized.
Internal-Use Software	The Company capitalizes qualifying proprietary software development costs that are incurred during the application development stage. Capitalization of costs begins when two criteria are met: (i) the preliminary project stage is completed, and (ii) it is probable that the software will be completed and placed in service for its intended use. Capitalization ceases when the software is substantially complete and ready for its intended use including the completion of all significant testing. Costs related to preliminary project activities and post implementation operating activities are expensed as incurred. Amounts capitalized are amortized over two years on a straight-line basis.
Impairment of Long-Lived Assets	The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset group may not be recoverable. Recoverability of assets held and used is measured by comparison of the carrying amount of an asset to the future undiscounted cash flows expected to be generated from the use of the asset and its eventual disposition. If such review indicates that the carrying amount of the asset group is not recoverable, the carrying amount of such assets is reduced to their fair value.
Goodwill	Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. Goodwill is not subject to amortization, but is reviewed for impairment on an annual basis or more frequently if events or changes in circumstances indicate that the carrying value of goodwill may not be recoverable. The Company performed a qualitative assessment during the fourth quarter of 2024 and determined that it is more likely than not that the fair value of its single reporting unit is greater than its carrying value. If it is determined that it is more likely than not that the fair value of the reporting unit is less than its carrying amount or if a qualitative assessment is not performed, then the Company would perform a quantitative goodwill impairment test as required, in which it would use a discounted cash flow approach to estimate the fair value of the reporting unit. If the fair value of the reporting unit is less than the carrying value, then a goodwill impairment amount is recorded for the difference.
Asset Retirement Obligations	The Company records asset retirement obligations (“AROs”) for the estimated cost of restoring its automated warehouse facilities to the specific condition required in accordance with the terms of its lease agreement, upon termination of the lease. AROs represent the present value of the expected costs and timing of the related obligations incurred. The ARO assets and liabilities are recorded in property and equipment, net within the machinery and equipment line item and other non-current liabilities, respectively, within the Company’s consolidated balance sheets. The Company records accretion expense, which represents the increase in the ARO, over the remaining estimated duration of the lease including renewal periods that are included in the lease term. Accretion expense is recorded in operations, product and technology expense in the consolidated statements of operations using accretion rates based on credit adjusted risk-free interest rates.
Leases	Under ASC 842, the Company determines if an arrangement is or contains a lease at inception by assessing whether the arrangement contains an identified asset and whether it has the right to control the identified asset. Lessees are required to classify leases as either finance or operating leases and to record a right-of-use (“ROU”) asset and a lease liability for all leases with a term greater than 12 months regardless of the lease classification. The lease classification will determine whether the lease expense is recognized based on an effective interest rate method or on a straight-line basis over the term of the lease. The Company determines the initial classification and measurement of its ROU assets and lease liabilities at the lease commencement date and thereafter if modified. ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Lease liabilities are recognized at the lease commencement date based on the present value of future lease payments over the lease term. ROU assets are based on the measurement of the lease liability and also include any lease payments made prior to or on lease commencement and exclude lease incentives and initial direct costs incurred, as applicable. As the implicit rate in the Company's leases is generally unknown, the Company uses its incremental borrowing rate based on the information available at the lease commencement date in determining the present value of future lease payments. The Company gives consideration to its existing credit arrangements, term of the lease, total lease payments and adjust for the impacts of collateral, as necessary, when calculating its incremental borrowing rates. The lease terms may include options to extend or terminate the lease when it is reasonably certain the Company will exercise any such options. Lease costs for the Company's operating leases are recognized on a straight-line basis within operating expenses over the lease term.
Seller Payable	Seller payable includes amounts owed to sellers upon the purchase of sellers’ goods by the Company or by buyers. Amounts are initially provided as a credit to sellers. These credits may be applied towards purchases from the Company, converted to third-party retailer or ThredUp gift cards or redeemed for cash.
Income Taxes	Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income on the years in which those temporary differences are expected to be recovered and settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company records interest and penalties related to unrecognized tax benefits in income tax expense.
Cost of Revenue	Cost of consignment revenue consists of outbound shipping, outbound labor and packaging costs. Cost of product revenue mainly consists of the inventory cost, inbound shipping related to the sold merchandise, outbound shipping, outbound labor, packaging costs and inventory write-downs. The classification of expenses varies across the retail industry. Accordingly, our cost of revenue may not be comparable to those of other companies in the retail industry.
Operations, Product and Technology	Operations, product and technology expenses consist primarily of distribution center operating costs and product and technology expenses. Distribution center operating costs include personnel costs, distribution center rent, maintenance and equipment depreciation as well as inbound shipping costs, other than those capitalized in inventory. Product and technology costs include personnel costs for the design and development of product and the related technology that is used to operate the distribution centers, merchandise science, website development and related expenses for these departments. Operations, product and technology expenses also include an allocation of corporate facilities and information technology costs including equipment, depreciation and rent.
Marketing	Marketing costs consist primarily of advertising, public relations expenditures and personnel costs for employees engaged in marketing. Marketing costs also include an allocation of corporate facilities and information technology costs including equipment, depreciation and rent.
Sales, General and Administrative	Sales, general and administrative expenses consist of personnel costs for employees involved in general corporate functions, including accounting, finance, tax, legal and people services, and customer service. Sales, general and administrative also includes payment processing fees, professional fees and allocation of corporate facilities and information technology costs such as equipment, depreciation and rent.
Stock-Based Compensation	Stock-based compensation costs are based on the fair values on the date of grant for restricted stock unit awards and stock options and on the date of enrollment for the employee stock purchase plan (“ESPP”). The fair values of restricted stock unit awards are based on ThredUp’s stock price on the date of grant. The fair values of stock options and ESPP are estimated using the Black-Scholes option-pricing model. The fair values of share-based awards are recognized as compensation expense over the requisite service period or over the period in which the related services are received (generally the vesting period), using the straight-line method. The determination of fair value for share-based awards on the date of grant using an option pricing model requires management to make certain assumptions regarding subjective variables. The Company accounts for forfeitures as they occur.
Fair Value Measurements	Fair value accounting is applied to all financial assets and liabilities that are recognized or disclosed at fair value in the consolidated financial statements on a recurring basis (at least annually). As of December 31, 2024 and 2023, the carrying amount of accounts receivable, other current assets, other assets, accounts payable, seller payable and accrued and other current liabilities approximated their fair value due to their relatively short maturities. Management believes the terms of its long-term variable-rate debt reflect current market conditions for an instrument with similar terms and maturity, therefore the carrying value of the Company’s debt approximated its fair value. Assets and liabilities recorded at fair value on a recurring basis on the consolidated balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair values. Fair value is defined as the exchange price that would be received for an asset or an exit price that would be paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The authoritative guidance on fair value measurements establishes a three-tier fair value hierarchy for disclosure of fair value measurements as follows: Level 1 — Observable inputs such as unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2 — Inputs (other than quoted prices in active markets included in Level 1) are either directly or indirectly observable for the asset or liability. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. For the Company’s marketable securities, which were all classified as available-for-sale, the Company utilizes third-party pricing services to obtain fair value. Third-party pricing methodologies incorporate bond terms and conditions, current performance data, proprietary pricing models, real-time quotes from contributing dealers, trade prices and other market data. The Company determined that the declines in the fair value of its marketable securities were not driven by credit-related factors. During the years ended December 31, 2024 and 2023, the Company did not recognize any losses on its marketable securities due to credit-related factors. As of December 31, 2024, the Company’s money market funds, were valued using Level 1 inputs because they are valued using quoted prices in active markets. The Company’s commercial paper, U.S. treasury securities, and U.S. government agency bonds were valued using Level 2 inputs because they are valued using quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.
