About SOSV

SOSV is a multi-stage venture capital firm operating several world-class vertical accelerator programs and providing seed, venture, and growth-stage follow-on funding to high-performing companies. Its full-stack model has delivered a net IRR over the past 20 years that ranks in the top 10% of venture funds globally. The firm also invests significant effort in social innovation and transformational impact, particularly in the fields of education and computing. SOSV’s mission is to fund amazing deep tech founders right at inception—often their very first check. SOSV’s General Partners work side-by-side with those founders to help ensure they build incredible companies that have a profound impact on human and planetary health. SOSV is the world’s most active deep tech, pre-seed venture capital firm, and SOSV uniquely offers its founders deeply resourced labs, offices, and event spaces in San Francisco, New York City, and Newark. In addition, SOSV has offices in Cork (Ireland / EU), Pune (India), Shenzhen (China), and Tokyo (Japan). At the start of 2026, SOSV’s 800 active portfolio companies had raised $7.3 billion and were valued at $18.2 billion. Each year, SOSV publishes the SOSV Deep Tech 100, the most promising frontier tech companies in the portfolio.
