Overview
Marble partners with scientists, engineers and operators to build climate-focused deeptech startups that reduce greenhouse gases, remove carbon, and cool the planet. Their main product is a venture studio that scours hard-to-abate climate problems and co-creates startup ventures with founding teams, starting at pre-seed, to bring breakthrough technologies to market. Founders-in-Residence work with Marble to identify high-impact climate opportunities and form companies with large emissions-reduction potential. Marble differentiates itself by actively creating and deploying radical, early-stage deeptech solutions rather than relying on traditional tech transfer, backed by climate and deep-tech investors. The goal is to move the world closer to net zero by delivering at least one gigaton of avoided or removed emissions through the startups they help build.
