Nov 2025Undisclosed stageYosemite (lead); M Ventures; AyurMaya; Balyasny Asset Management; Alexandria Venture Investments; SymBiosis; Abingworth; General Atlantic; DC Ventures; B Capital; Ally Bridge Group; Surveyor Capital$120MSolve Therapeutics is a clinical-stage biotechnology company developing best-in-class antibody-drug conjugates (ADCs) for solid tumors, leveraging its proprietary CloakLink linker technology for improved stability, pharmacokinetics, and therapeutic index. Founded by leaders from VelosBio (acquired by Merck) and Acerta Pharma (acquired by AstraZeneca), the company integrates ADC engineering with novel patient-selection diagnostics. Its lead candidates, SLV-154 (targeting head and neck cancer, non-small cell and small cell lung cancers, bladder tumors) and SLV-324, are in Phase 1 trials, with the new funding supporting completion of Phase 1b studies and operational expansion. On November 17, 2025, Solve Therapeutics raised $120 million in an oversubscribed financing round led by Yosemite, with participation from new investors Abingworth, Ally Bridge Group, B Capital, Balyasny Asset Management, Merck & Co., and SymBiosis, plus returning investors Alexandria Venture Investments, AyurMaya, DC Global Ventures, General Atlantic, and Surveyor Capital. This follows a $75 million round in December 2024 and a prior $126 million Series A, bringing total capital raised to $321 million. The round involved issuance of convertible preferred stock. The funding accelerates clinical development of SLV-154 and SLV-324 toward later-stage trials, with CEO Dave Johnson noting trials are enrolling ahead of schedule. Investors highlighted Solve's potential in precision oncology.
Dec 2024Undisclosed stage-$75MSolve Therapeutics is a San Diego-based clinical-stage biotechnology company founded in 2021, developing best-in-class antibody-drug conjugates (ADCs) for solid tumors using its proprietary CloakLink linker technology for improved pharmacokinetics, plasma stability, and lower toxicity, combined with a novel diagnostic platform for patient selection. Led by CEO and co-founder Dave Johnson, previously of VelosBio (acquired by Merck for $2.75B), the company's lead assets SLV-154 and SLV-324 are in Phase 1 trials for metastatic solid tumors, with plans to complete Phase 1b studies. The company completed a $75M financing in December 2024, followed by a $120M oversubscribed round announced November 17, 2025, led by Yosemite with participation from Abingworth, Merck & Co., Alexandria Venture Investments, Surveyor Capital (Citadel), Ally Bridge Group, B Capital, Balyasny, SymBiosis, and others, bringing total capital raised to $321M since inception (including an initial $126M Series A). The $120M funds acceleration of clinical development toward IND-readiness, operational expansion for later-stage trials, and generation of data on CloakLink's advantages. The ADC field sees high M&A activity, e.g., Pfizer-Seagen $43B, but Solve remains independent and well-funded for pipeline advancement.
