Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation These condensed consolidated financial statements are unaudited and should be read in conjunction with the Company’s most recent annual audited consolidated financial statements and notes thereto. These condensed consolidated financial statements have been prepared in accordance with the instructions for the Securities and Exchange Commission’s (“SEC’s”) Form 10-Q and Article 10 of Regulation S-X. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to rules and regulations of the SEC, although the Company believes that the disclosures are adequate to make the information presented not misleading. In the opinion of management, all adjustments, consisting only of normal recurring adjustments considered necessary for a fair presentation of results of operations and financial position, have been included. We use the same accounting policies in preparing quarterly and annual financial statements. During the six months ended June 30, 2025 (Successor), we identified an error and recorded an immaterial out of period adjustment of $12,448 to correct an overstatement of Additional paid-in capital, an immaterial out of period adjustment of $4,468 to correct understatement of Net loss attributable to Innventure, Inc. stockholders and an immaterial out of period adjustment of $16,915 to correct an understatement of Non-controlling interest. The impact of the adjustments are not material to the condensed consolidated financial statements for any interim or annual periods prior to June 30, 2025 nor the current financial period. The out of period adjustment to Additional paid-in capital is included in the Non-controlling interest issued and related transfers within the condensed consolidated statements of changes in mezzanine and stockholders’ equity (deficit) and the adjustment related to Net loss attributable to Innventure, Inc. within Comprehensive loss attributable to Non-redeemable non-controlling interest on the condensed consolidated statements of operations and comprehensive income (loss).	Basis of Presentation The consolidated financial statements of the Company are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). The Successor consolidated financial statements include the accounts of the Company, its wholly owned or majority-owned subsidiaries and entities in which the Company is deemed to have a direct or indirect controlling financial interest based on either a variable interest model or voting interest model. The Predecessor consolidated financial statements include all amounts of Innventure LLC and its consolidated subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.
