A Deep Tech Dream Team

SOSV’s ten General Partners draw on deep experience as investors, entrepreneurs, operators, scientists and engineers. They operate as three teams, one at each location, and each ready for founders across the full breadth of deep tech, from physical AI to therapeutics, energy to critical minerals. Each location also has unique strengths, such as Silicon Valley’s investor networks, New York’s corporate and healthcare ecosystem, and Newark’s embedded design engineering and prototyping. SOSV founders have access to everything.

The Best Data and Global Reach

In addition to being the the most active pre-seed deep tech investor, SOSV gathers fine-grain data on deep tech trends through regular VC-Founder Matchups, the annual Climate Tech Summit, and the Deep Tech Live series, which engage thousands of founders each year. SOSV is no less at home in Silicon Valley than the global ecosystem. Founders in the 800+ company portfolio hail from 82 countries and operate in 58. In addition to its US offices, SOSV has teams working in India, China, and the EU, and SOSV’s 2700+ co-investors span the globe.

An Infrastructure For Builders

In the past decade, SOSV raised more than $50 million in grants to build and outfit 85,000 sq feet of labs, offices and event spaces in San Francisco, New York City, and Newark. Available labs include bio-safety (BSL1 and BSL2), chemical, mechatronics, analytics, and electrical engineering, with staff experts on hand to help. Specialists in Pune, Shenzhen, and Tokyo round out SOSV’s 24/7 global innovation engine, bringing additional design, engineering, and supply chain expertise to bear.

A Focus on Follow-ons and Exits

SOSV’s pre-seed check is just the start. Investor teams work with each founder to identify the best prospects in SOSV’s vast investor network, make individual introductions, and host carefully targeted demo days and matchups. SOSV joins early stage follow-on rounds, at least through Series B. SOSV also believes founders should understand exit strategies. The unique SOSV RETVRN program, free to SOSV companies, helps founders control their destinies.

A Lifetime Cohort

The startup crucible in the labs and offices of San Francisco, New York City, and Newark yield friendships and networks that last a lifetime. SOSV’s general partners and program staff remain trusted advisors long after the founders move on. SOSV continues helping founders raise investment, expand networks, make corporate contacts, and earn press coverage. Founders participate as VIPs in VC-Founder Matchups and speak on panels at the SOSV Climate Tech Summit, expos and other events. SOSV is for life.
