SOSV is a global venture capital firm and accelerator founded in 1995, operating one of the most active deep tech and life sciences investment programs in the world. The firm runs multiple accelerator programs, including HAX for hardware and robotics, IndieBio for life sciences and biotech, and Orbit for climate and sustainability — providing intensive company-building support alongside early-stage capital.
With over $1.5 billion in AUM and a portfolio exceeding 1,000 companies across more than 70 countries, SOSV occupies a distinctive position in the venture landscape: a programmatic investor that takes companies from idea stage through to growth and beyond. The firm's accelerator model means it is often the first institutional check into a company, with follow-on capability through later rounds.
SOSV has a strong impact orientation across its portfolio, with climate, food systems, health, and sustainability representing a significant share of its investments. Its programs in particular have become known as launchpads for companies working on hard scientific and engineering problems that require more than capital to succeed.
SOSV invests at the earliest stages of deep tech, life sciences, and climate companies through its global accelerator programs. The firm backs founders working on hard problems — hardware, biology, materials, food systems, climate technology,that require both capital and hands-on technical support to reach commercial viability.
SOSV's thesis is programmatic: it invests in cohorts through structured accelerator programs, providing lab access, mentorship, corporate partnerships, and follow-on funding. This model is designed for founders who need more than a check — companies at the frontier of science and engineering where the path from lab to market requires active infrastructure support.
