Marble is the only deeptech venture studio in Europe focused exclusively on climate. Our north star is to erase several gigatons from annual greenhouse gas emissions, and create the industrial foundations of a climate resilient future. We need many shots on goal to achieve this. This means we optimise for this outcome, and provide the best specialised support to Founders committed to this mission.

With expertise in applied science, climate, and a track record in company building, our core team will shortcut your learning and make sure you’re on the right track. Our Partners have supported hundreds of pre-company Founders, who went on to create 30+ startups in AI, biotech, materials, fusion, and more. As advisors or angel investors, we helped them raise capital from top VCs, for over $250m in value creation. At Marble, you will be able to tap into an unparalleled network of technical experts, industry leaders, climate investors, mentors and emerging Founders in climate tech.

Finding a high leverage climate idea can be hard. Turning it into a successful company is even harder. At Marble we actively scope opportunity areas in climate deeptech. You get the support of an in-house research team, insights from our investment thesis, and streamlined access to our expert network. So you’re not starting from scratch.

We bet on the combination of Founder potential and well-defined problems to develop radical solutions for hard climate problems. This differs from other programmes designed for IP commercialisation or large cohorts. We call it "reverse tech transfer.” Through systematic de-risking at every step of the way, we’ll help you build a venture optimised for climate impact and market success.

You’ll be supported with a €2,500-€3,000 monthly payment through the programme. If you succeed, we will invest €250,000 in your new company. You and your team will own 80% at pre-seed. While other studios tend to keep a much larger share, our ratio incentivises everyone for long-term success, and leaves more room for follow-on investors.

We are based in Paris, France, with access to top talent, science, capital, and corporate customers, local and international. Working in the heart of Europe, you will leverage an ecosystem with strong incentives toward net zero targets, and high arbitrage opportunity for ambitious deeptech Founders. We can sponsor your Founder Visa if you wish to relocate in France. Remote participation is possible, preferably from Europe and with regular in-person meetings.
