Lowercarbon Capital

Lowercarbon Capital backs companies that cut new CO2 emissions, remove legacy carbon, or build climate resilience, with the philosophy that markets, not guilt, will fix the planet. Founded in 2018 by Chris and Crystal Sacca with Clay Dumas, the Wyoming-based firm manages over $2B across general climate, carbon removal and fusion-specific vehicles. Notable industrial bets include Commonwealth Fusion Systems, Antora (thermal batteries), Crusoe (low-emission compute), Solugen (bio-based chemicals) and Avalanche Energy (modular fusion). Stage focus is seed and Series A.
