Lowercarbon Capital
Chris and Crystal Sacca's climate-only venture firm: a loud, profane, founder-friendly early-stage investor that turned the Lowercase Capital fortune and brand into ~$2bn of climate funds, and made carbon removal, fusion and "buy-curious" commercial decarbonisation its signature themes.
