What Bay Bridge Ventures does
Bay Bridge Ventures is an institutional venture capital firm founded in February 2022 in Berkeley, California, focused on early-stage investments in disruptive technology startups addressing climate change, with additional thesis areas in health innovation and inclusive capitalism. The firm employs a proprietary "ESG+ Methodology" as its core investment framework, described as an industry-leading ESG and impact assessment tool that combines traditional venture diligence with codified sustainability criteria. It is structured as a standard institutional VC fund (legal entity: Bay Bridge Ventures Management LLC) generating returns through management fees and carried interest on committed capital from limited partners.
The firm has no technology product or software platform; its output is capital deployment plus strategic value-add to portfolio companies. Distribution of capital occurs via direct equity investments in early-stage funding rounds, with a global mandate despite a North American operational base. The three founding General Partners — Andrew Karsh (10-year CalPERS Portfolio Manager, ex-Credit Suisse Alternative Investments), Joe Blair (formerly of Cota Capital, Obvious Ventures, and Chrysalix Venture Capital), and Kim Kolt (Founder of For Good Ventures, ex-Goldman Sachs TMT) — collectively bring over 60 years of institutional investing and operating experience.
Bay Bridge Ventures' go-to-market relies on institutional investor networks (leveraging the founders' CalPERS and Credit Suisse alumni relationships), industry events, press coverage, and a strategic advisory board that includes senior figures from Breakthrough Energy Ventures (Tom Baruch, Carmichael Roberts), Sidewalk Labs (Prem Ramaswami), Nephila Climate (Barney Schauble), Material Impact, Credit Suisse First Boston (Brian Finn), and GoodLeap (Daniel Glenn). Publicly disclosed portfolio activity includes participation in Apeiron Labs' $9.5M Series A (February 2026), Exowatt's Series A extension to $120M (November 2025), and early-stage/board positions in Turntide Technologies, Legends of Learning, and Sustainable Ocean Alliance. The firm commits to dedicating a significant portion of carried interest to philanthropic causes and pre-revenue mission-driven startups.
