Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation The unaudited condensed consolidated financial statements include the accounts of Weave Communications, Inc. and its wholly-owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial reporting. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. Accordingly, these unaudited interim condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on March 5, 2026. The accompanying unaudited interim condensed consolidated balance sheets, statements of operations and comprehensive loss, statements of stockholders' equity, statements of cash flows and accompanying notes are unaudited. These unaudited interim condensed consolidated financial statements have been prepared on a basis consistent with the annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for the fair statement of the Company’s financial condition, its operations and cash flows for the periods presented. The historical results are not necessarily indicative of future results, and the results of operations are not necessarily indicative of the results to be expected for the full year or any other period. Segments The Company determines its operating and reportable segments based on how the chief operating decision maker (“CODM”), who is the Company’s Chief Executive Officer (“CEO”), reviews and manages the operating results of the business to evaluate segment performance and allocate resources within the business. As described in Note 15, the Company operates as one operating and reportable segment. Use of Estimates The preparation of the unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amount of sales and expenses during the reporting period. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. The Company adjusts such estimates and assumptions when facts and circumstances dictate. Actual results could differ from those estimates. Significant estimates included in the Company’s financial statements include the valuation allowance against deferred tax assets, allowance for credit losses, recoverability of long-lived assets, fair value of stock-based compensation, the amortization period of deferred contract costs, and the valuation and useful lives of acquired intangible assets. Significant Accounting Policies A summary of the Company’s significant accounting policies is discussed in Note 2 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on March 5, 2026. There have been no significant changes to these policies during the three months ended March 31, 2026. Accounting Pronouncements Adopted In July 2025, the FASB issued ASU No. 2025-05, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets” (“ASU 2025-05”), which amended the guidance in ASC 326 to simplify the estimation of credit losses on accounts receivable and contract assets from revenue transactions. The amended guidance allows companies to elect a practical expedient to assume that the conditions as of the balance sheet date will remain unchanged for the remaining life of the asset when estimating the expected credit losses of the asset. This update is effective for annual periods beginning after December 15, 2025 and interim periods within those annual periods. The Company adopted this standard prospectively and the adoption of this standard did not have a material impact on the Company’s unaudited condensed consolidated financial statements. Accounting Pronouncements Pending Adoption In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”), which requires the disclosure of specific categories in the rate reconciliation and greater disaggregation for income taxes paid. ASU 2023-09 will be effective for annual periods beginning after December 15, 2025 and should be adopted prospectively with the option to be adopted retrospectively. The Company is currently evaluating the impact of ASU 2023-09 on its related disclosures. In November 2024, the FASB issued ASU No. 2024-03, “Income Statement (Topic 220): Disaggregation of Income Statement Expenses” (“ASU 2024-03”), which requires additional disclosures of certain amounts included in the expense captions presented on the statement of operations and comprehensive loss as well as disclosures about selling expenses. ASU 2024-03 is effective on a prospective basis, with the option for retrospective application, for annual periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027, and early adoption is permitted. The Company is currently evaluating the impacts of adopting this guidance on its unaudited condensed consolidated financial statement disclosures and statements of operations and comprehensive loss. In September 2025, the FASB issued ASU No. 2025-06, “Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software” (“ASU 2025-06”), which updates the criteria for capitalization of internal-use software and the associated required disclosures. ASU 2025-06 will be effective for annual periods beginning after December 15, 2027, and should be adopted prospectively with the option to be adopted retrospectively. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2025-06 on its related disclosures, statements of operations and comprehensive loss, and balance sheets. In December 2025, the FASB issued ASU No. 2025-11, “Interim Reporting (Topic 270): Narrow-Scope Improvements, which clarifies interim disclosure requirements and the applicability of Topic 270. ASU 2025-11 will be effective for interim reporting periods within annual reporting periods beginning after December 15, 2027, and can be applied either prospectively or retrospectively. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2025-11 on its interim reporting. As an “emerging growth company,” the Jumpstart Our Business Startups Act (the “JOBS Act”) allows the Company to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. The Company has elected to use the adoption dates applicable to private companies. As a result, the Company’s unaudited condensed consolidated financial statements may not be comparable to the unaudited condensed consolidated financial statements of issuers who are required to comply with the effective date for new or revised accounting standards that are applicable to public companies. Beginning on December 31, 2026, the Company will no longer qualify for emerging growth company status; as such, future accounting pronouncements will be adopted in accordance with the adoption dates applicable to public companies.
