 It’s no secret that France has big ambitions in deeptech. 

The country has one of the biggest deeptech funds in Europe: France’s public investment arm Bpifrance has €2bn to deploy in research-based startups.

France also has the talent. The country is home to top universities such as Paris-Saclay University (which competes with Princeton as the world’s best-rated mathematics school), Pierre and Marie Curie University and PSL University Paris. 

So which are the deeptech startups that have the most promise? To find out, we asked six top French investors which companies they were most excited about. There was only one rule: they could not plug the companies in their own portfolios.

C12 Quantum Electronics

What’s the tech? Quantum processors made of carbon nanotubes

What problem is it trying to solve? 

“C12 addresses the two main challenges of quantum computing as of today: the current hardware architecture does not allow for an acceptable level of miniaturisation and is prone to a high level of error. C12 has developed a new type of hardware structure that relies on a new type of material called carbon nanotubes. It’s tech that’s smaller and easier to integrate into chips –– and has a lower error rate and energy consumption.”

What’s the tech? Cruelty-free leather from cultured cells

What problem is it trying to solve?

“Brands are under tremendous pressure to be more ethical and sustainable, and raw materials are an important part of the equation. Leather is probably the most controversial one. Faircraft develops a sustainable labgrown alternative to animal leather.

"Today, the main options are leather recycling or plant-fibre material, but Faircraft goes further and mimics nature in the lab by reproducing the real animal skin to get the same properties of traditional leather. The team is highly skilled and got their first promising prototypes. I’m excited to see their first product developed for luxury brands.”


Faircraft was also selected by Benjamin Joffe of SOSV.  

Founded: 2021

What’s the tech? Capture and convert CO₂ into chemical products

What problem is it trying to solve? 

“Recycling CO₂ to transform it into valuable raw materials: this is the ambition driven by cofounders Sarah Lamaison and David Wakerley, two young researchers from Ecole Polytechnique in France and Stanford University. CO₂ is transformed into chemical feedstocks such as carbon monoxide, methane or hydrocarbons via electrolysis.

"The next few years will serve to test the tech performance on a larger scale and see if it’s financially profitable. Dioxycle could drastically reduce the polluting emissions of industrial sites, according to the company.”

Sarah Lamaison received the French Young Talents L’Oréal-UNESCO for Women in Science Prize in 2020. 

Founded: 2020

Latest funding: funding from i-Lab
