Accounting Policies [Abstract]
Significant Accounting Policies	SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation The Condensed Consolidated Financial Statements (Unaudited) include the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Summary of Significant Accounting Policies There have been no significant changes to our significant accounting policies as of and for the three and six months ended June 30, 2025 as compared to the significant accounting policies described in our Form 10-K. Concentrations of Risk Financial instruments that potentially subject us to concentration of credit risk consist of cash and cash equivalents. We only invest in high-credit-quality instruments and maintain our cash equivalents in fixed-income securities. We place our cash primarily with domestic financial institutions that are federally insured within statutory limits. For the purpose of assessing the concentration of credit risk with respect to accounts receivable and significant customers, we treat a group of customers under common control or customers that are affiliates of each other as a single customer. For the three and six months ended June 30, 2025 and 2024, we did not have any customers that accounted for more than 10% of our revenue. As of June 30, 2025, we had one customer that accounted for 16% of our net accounts receivable balance, which was collected within typical business terms. Our business model relies on educational content and credentialing programs from content creators. Our largest content creator has global brand recognition and supplies a variety of in-demand content across multiple domains. The loss of, or significant reduction in, this partnership or one of our other large content creator relationships could have a material adverse effect on our financial position, results of operations, and cash flows. Use of Estimates The preparation of the Condensed Consolidated Financial Statements (Unaudited) in conformity with GAAP requires management to make estimates, judgments, and assumptions that affect the reported amounts of assets and liabilities and related disclosures as of the date of the Condensed Consolidated Financial Statements (Unaudited), as well as the reported amounts of revenue and expenses during the reporting period. We base our estimates on historical experience, current conditions, and various other factors that we believe to be reasonable under the circumstances. Significant items subject to such estimates, judgments, and assumptions include, but are not limited to, those related to the determination of principal versus agent and variable consideration in our revenue contracts; stock-based compensation expense; period of benefit for capitalized commissions; internal-use software costs; useful lives of long-lived assets; the carrying value of operating lease right-of-use assets; the valuation of intangible assets; loss contingencies and potential recoveries; and income tax expense, including the valuation of deferred tax assets and liabilities, among others. Actual results could differ from those estimates, and any such differences could be material to our Condensed Consolidated Financial Statements (Unaudited). Impairment of Assets Deferred Costs, Net and Other Assets During the three and six months ended June 30, 2025, we recognized impairment losses of $1.2 million on deferred partner fees and $1.0 million on content development grants, which we do not expect to recover. These impairment losses were recorded within cost of revenue and sales and marketing expenses, respectively, in the Condensed Consolidated Statements of Operations. No impairment losses were recognized during the three and six months ended June 30, 2024. Intangible Assets, Net Impairment losses related to content assets were immaterial during the three and six months ended June 30, 2025 and 2024. Recent Accounting Pronouncements Recently Issued Accounting Pronouncements Not Yet Adopted In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires public entities on an annual basis to disclose (1) specific categories in the tax rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. This ASU will be effective for annual reporting periods beginning with our fiscal year ending December 31, 2025. The amendments should be applied on a prospective basis, though retrospective application is permitted. We preliminarily expect the new ASU to result in disclosure of disaggregated data about our tax payments within certain U.S. states, India, Canada, and the U.K. We are evaluating the components of our tax rate reconciliation to ensure disclosure of sufficient information to enable users of our financial statements to understand the nature and magnitude of factors contributing to the difference between the effective tax rate and the statutory tax rate. In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40), which requires disclosure, on an annual and interim basis, of specified disaggregated information about certain costs and expenses. Additionally, in January 2025, the FASB issued ASU 2025-01, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40), to clarify the effective date of ASU 2024-03. ASU 2024-03 will be effective for annual reporting periods beginning with our fiscal year ending December 31, 2027 and for interim reporting periods beginning with our fiscal quarter ending March 31, 2028, with early adoption permitted. The amendments may be applied either prospectively or retrospectively. We are currently evaluating the impact ASU 2024-03 will have on our financial statement disclosures.
