SOSV invests in deep technology at pre-seed, focusing on human and planetary health and providing founders with laboratory, engineering and company-building facilities.
Its locations in New York, Newark and San Francisco combine workspace with specialist resources for developing scientific and physical products. The model is designed for founders who need experimental facilities alongside early capital.
Its work spans biotechnology, industrial production and climate-related technologies. SOSV also organises investor matchups and a Deep Tech Summit, connecting companies with prospective financing partners as they move from technical development toward commercialisation.
