Join Us On Day Zero,
Towards Net Zero

We know that building climate deeptech is a hard journey. It’s even harder when you’re starting alone. We created Marble to make your journey easier.

How it Works

1. Explore

Find The Best Idea

We will scope impact areas where your skills can unlock radical solutions to hard climate problems.

2. Create

Turn The Idea Into a New Company

We will work together to turn the most promising idea into an investable pre-seed company.

3. Build

Take Your Startup Into The World

If you succeed, you and your co-founders will lead a new company and we'll be your first backer.

Who Should Apply?

We are looking for scientists, engineers and operators with deep domain expertise related to opportunity areas we’re pursuing. We are also open to hear about broader idea spaces in climate on which we haven’t formed a thesis yet.

Our two most important selection criteria are your technical/domain insights as well as your potential to lead a massively scalable company. No need for a team, IP, or even a specific idea.

What we look for

Marble totally changed my life. As a young PhD, turning my skills into a business seemed like an impossible mountain to climb. Marble gave me the confidence and know-how to chase my dreams as an entrepreneur.

Meet the Mentors —

Meet the mentors

We've brought together top founders, researchers, policy makers, operators and investors to further support our Founders during their journey at Marble. As a Founder at Marble, you'll benefit not only from our teams support, but get access to this group of top minds in climate.

Why Build With Us?

  1. Climate Focus

    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.

  2. Team & Network

    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.

  3. Insights & Expertise

    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.

  4. Optimised Process

    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.

  5. Funding

    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.

  6. Ecosystem

    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.
