Lowercarbon Capital was founded in 2018 by Chris Sacca, Crystal Sacca, and Clay Dumas, following Chris's earlier career building Lowercase Capital into one of the most successful venture funds in history through early bets on Uber, Twitter, Instagram, and Stripe. Rather than treat climate investing as philanthropy, Lowercarbon applies the same venture-scale return expectations Sacca used chasing consumer tech winners to companies that profitably slash or remove carbon emissions - a deliberately blunt positioning the firm sums up in its own unfiltered mission language. The firm raised its first $800 million in outside capital within days in 2021, added a dedicated $350 million carbon-removal fund in 2022, and now manages roughly $2 billion across more than 100 portfolio companies spanning energy, industrial materials, transportation, and advanced manufacturing.
No confirmed public exit yet - Lowercarbon's flagship bets (Commonwealth Fusion Systems, Charm Industrial, Solugen, Zap Energy) remain private, hard-tech climate companies still working toward commercial deployment
