Marble is a climate tech venture studio solving hard climate problems. Our mission: bring us at least one gigaton closer to net zero and create a future that thrives. We do this by partnering with scientists, engineers and operators to build deeptech startups that slash emissions, remove carbon, and cool the planet. The climate crisis is the most pressing challenge of our times. Solving it requires breakthrough technology, as available solutions only get us halfway. We can’t put all our hopes in classic tech transfer. We need to intentionally create and deploy radical solutions for hard-to-abate emissions. Backed by top climate and deep tech investors, we're searching for individuals who could apply their skills to solve hard climate problems and who have the will to turn their skills into a new startup company. Joining as Founders-in-Residence, they work with us to scope high-impact climate opportunities and build ventures with massive impact potential. We invest in the best teams at pre-seed.

Vestico combines AI & user-generated content to show shoppers how clothes fit before they buy & collect actionable data throughout their shopping journey. Most of us don't look like the models we see online, so it's difficult to make the right decisions about size and fit. Returns in fashion e-commerce can go as high as 60% and cost retailers over $500B every year in the US alone. Far more importantly, e-commerce returns are having a devastating impact on our planet due to emissions, repackaging, restocking, and waste, with over six billion pounds of returned clothes ending up in landfill in 2019. Vestico solves the returns problem for retailers by showing shoppers how products look on people just like them. We give shoppers the confidence to buy and the information to buy intelligently, reducing returns and boosting conversion. By combining the authenticity of user-generated content with sizing AI, Vestico supports diverse representation at scale while solving the online fashion shopper's biggest pain point.

WHOAMI is building a new category at the intersection of social gaming, identity, and real-world incentives. We believe human identity is the most underutilized form of interactive content on the internet. On WHOAMI, creators publish carefully designed personal statements — and the community engages by analyzing, predicting, and staking on which one is true. It’s psychology, tension, and social dynamics packaged into a structured prediction game. Today’s platforms are passive. Gambling platforms are impersonal. Creator platforms lack real stakes. WHOAMI introduces high-engagement social mechanics powered by structured incentives and transparent game design. Our ambition is bold: Turn human curiosity into a scalable entertainment layer. We are currently in pre-launch, designing a web MVP built for scale from day one. We’re assembling a founding team to architect the platform, own the technical vision, and build a product capable of handling real-time transactions, trust systems, and high-engagement loops. This is not a side project. This is a category play.
