Similar firms

Blue Bear Ventures$100K–$400K

Co-founder-focused fund for lab-based teams at the health–climate intersection (gene therapy, synthetic biology, batteries), offering deep access to UC Berkeley, UCSF, MIT and Stanford research and scientist-founders. Blue Bear Ventures spun out of UC Berkeley's CITRIS Foundry deep tech accelerator and maintains unique relationships with top research labs at UC Berkeley, UCSF, MIT, and Stanford, giving them unusually deep access to scientist-founders and university research. The fund focuses specifically on co-founding teams from labs working at the intersection of health and climate—such as gene therapy, synthetic biology, and next-generation batteries—rather than investing in lone founders or abstract ideas.

Horizons Ventures$1M–$25M

Invests in disruptive, technology-focused startups; established in 1999.

Lux Capital$100K–$100M

Early institutional backer that sources tech from academia and government labs, partnering with scientist- and engineer-led teams to deeply interrogate science, dual-use/defense opportunities, and amplify through an in-house media platform. Explicitly aims to "turn science fiction into science fact" by backing companies at the intersection of the new and the not-yet-imagined, built around scientists, engineers, and polymaths rather than traditional finance backgrounds who can deeply interrogate emerging science and complex tech. The firm systematically mines academia and government labs for "technological gems" and has become one of the earliest institutional backers of dual-use and defense technology.

Creative Ventures$1M–$3M

Targets companies addressing labor shortages in manufacturing, construction, logistics, and food production; cutting healthcare costs from aging and chronic disease; and enabling sustainable food production for growing populations.

Divergent Capital$250K–$1M

Pre-seed lead investor for deeply technical AI, biotech, climatetech and infrastructure startups, offering female operator-led go-to-market expertise and structured fellowships to source technical-founder deal flow.
