| Date | Stage | Investors | Raised | Deal Summary |
|---|---|---|---|---|
| Jun 2026 | Series B | Vida Ventures (lead); Illumina Ventures; CureDuchenne Ventures; Vertex Ventures HC; SymBiosis; Otsuka Pharmaceuticals; UCB Ventures; Vivo Capital; Leaps by Bayer; ARK Investment Management; Medical Excellence Capital; ARCH Venture Partners | $125M | Vida Ventures led an oversubscribed USD 125 million Series B financing in SonoThera, with participation from ARK Invest and other strategic and financial backers. The round was announced and closed in June 2026, and the proceeds are intended to advance SonoThera’s lead programs for Duchenne muscular dystrophy and autosomal dominant polycystic kidney disease into the clinic, while expanding its broader pipeline of ultrasound-mediated nonviral genetic medicines. The financing is structured as venture equity rather than an acquisition or debt transaction, and the sources do not disclose a valuation, revenue, or EBITDA figure. Strategically, the raise supports development of SonoThera’s RIPPLE ultrasound delivery and PORE payload engineering platforms, which the company positions as a nonviral alternative to traditional gene therapy. The company says the capital will fund clinical progress for its lead programs and broaden its pipeline across multiple organ systems. ARK Invest participated alongside Vida Ventures, Leaps by Bayer, Otsuka Pharmaceutical, UCB Ventures, CureDuchenne Ventures, Vivo Capital, SymBiosis, and several existing investors, indicating a broadly syndicated late-stage venture round. SonoThera is a South San Francisco-based biotechnology company focused on next-generation genetic medicines aimed at the root causes of disease. Its disclosed near-term development priorities are DMD and ADPKD, with the first DMD trial targeted for 2027. The company describes its platform as ultrasound-mediated, targeted, and redosable, and the round is meant to help move these programs from preclinical development into the clinic. |

Founded by Kenneth Greenberg, Michael Davidson, and Steve Feinstein, the company focuses on genetic medicines treating root causes of diseases. On December 5, 2022, SonoThera closed a $60.75 million Series A funding round led by ARCH Venture Partners, with participation from Illumina Ventures, Johnson & Johnson Innovation – JJDC, Vertex Ventures HC, Medical Excellence Capital, Eli Lilly & Company, Alexandria Venture Investments, Lifespan Investments, Formic Ventures, Foothill Ventures, and Wilson Sonsini Goodrich & Rosati. Proceeds will support platform optimization, preclinical development, early manufacturing, initial proof-of-concept in humans, and team expansion from 13 full-time employees plus consultants to about 20 by mid-2023. The company plans to select a lead program targeting hard-to-reach areas or superior therapeutic features, with first Phase I trial hoped for 2025. As of September 2024, the company remained active with total funding at $60.75M from this sole round listed. In January 2026, SonoThera announced launch of a $125M Series B at the J.P.
