SOSV

SOSV is a global venture firm that operates a portfolio of accelerator and seed programs including HAX for hard-tech and robotics, IndieBio for biology and life sciences, Orbit for Ireland-focused early-stage companies, and a dedicated digital health and climate strategy. The firm’s defining characteristic is its early, hands-on engagement, often pre-product, providing capital alongside lab space, engineering support, and a structured program. Check sizes from SOSV typically begin in the range of two hundred fifty thousand to five hundred thousand dollars at program entry, with meaningful follow-on through dedicated growth vehicles that can scale total commitments to several million dollars over time. Healthcare AI founders should focus on the IndieBio or digital health practices, depending on whether the company is biology-driven or software-led, and the natural fit is a deeply technical team willing to engage with the program structure and benefit from on-site mentorship and infrastructure. AI software companies without a wet-lab or hardware element are still in scope through the digital health and broader generalist strategies. Founders not interested in the program structure or co-location requirements should look elsewhere. The best entry path is direct application to the relevant program through the SOSV website, or a warm referral from a portfolio CEO or program alumnus. Expect a structured, milestone-driven relationship from day one.
