Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Description of Business	Organization and Description of Business Senti Biosciences, Inc. and its subsidiary (the “Company” or “Senti”), is a clinical stage biotechnology company developing next-generation cell and gene therapies engineered with its gene circuit platform technologies for patients living with incurable diseases. Senti’s mission is to create a new generation of smarter therapies that can outsmart complex diseases using novel and unprecedented approaches. Senti has built a synthetic biology platform that enables it to program next-generation cell and gene therapies with gene circuits. These gene circuits, which are created from novel and proprietary combinations of DNA sequences, reprogram cells with biological logic to sense inputs, compute decisions and respond to their cellular environments. The Company is headquartered in South San Francisco, California. Liquidity and Going Concern These condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) assuming the Company will continue as a going concern. The going concern assumption contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The condensed consolidated financial statements do not include any adjustments to the carrying amounts and classification of assets, liabilities, and reported expenses that may be necessary if the Company were unable to continue as a going concern. The Company has devoted substantially all of its efforts to organizing and staffing, business planning, raising capital, and conducting preclinical and clinical studies and has not realized substantial revenues from its planned principal operations. As of June 30, 2025, the Company raised aggregate gross proceeds of $356.9 million from the merger in 2022, the issuance of shares of common stock, the issuance of shares of redeemable convertible preferred stock, the issuance of convertible notes, and, to a lesser extent, through collaboration agreements and governmental grants and loans. As of June 30, 2025 and December 31, 2024, the Company had an accumulated deficit of $326.0 million and $297.1 million, respectively. The Company’s net losses were $28.8 million and $23.3 million for the six months ended June 30, 2025 and 2024, respectively. Substantially all of the Company’s net losses resulted from costs incurred in connection with the Company’s research and development programs and from general and administrative costs associated with the Company’s operations. The Company expects to incur substantial operating losses and negative cash flows from operations for the foreseeable future as the Company advances its preclinical activities and clinical trials for its product candidates in development. The Company concluded that substantial doubt continued to exist and that the Company’s cash and cash equivalents of $21.6 million as of June 30, 2025, were not sufficient for the Company to continue as a going concern for at least one year from the issuance date of these condensed consolidated financial statements. Additional funds will be necessary to maintain current operations and to continue research and development activities. The Company’s continued existence is dependent upon management’s ability to raise capital and ultimately develop profitable operations. While management is devoting substantially all of its efforts to developing the Company’s business and raising capital, there can be no assurance that these efforts will be successful. Moreover, no assurance can be given that management’s actions will result in raising additional financing or profitable operations.
