Marble

Venture studio building climate-decarbonization startups

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.

Simplify's Take

What believers are saying

  • CryoBio validates Marble's model in agriculture adaptation and frost protection.[6]
  • Studio thesis spans industrial decarbonization, carbon capture, cooling, and critical minerals.[6][9]
  • Hands-on support spans research, customer interviews, technoeconomics, IP, and fundraising.[8]

What critics are saying

  • Deeptech venture creation requires elite talent; weak founder supply slows new company formation.[1][8]
  • Reverse tech transfer front-loads capital before product-market fit, increasing thesis selection risk.[5][9]
  • Long commercialization cycles and capital intensity can outrun Marble's pre-seed financing.[6][8]

What makes Marble unique

  • Europe's only deeptech climate venture studio focuses on reverse tech transfer.[5]
  • Founders-in-Residence spend 12 months exploring opportunity areas before spinout.[1][4][5]
  • Marble provides €2,500-€3,000 monthly support and €250,000 pre-seed capital.[5][8]
