Investing across France
We look for founders who have worked on the problem themselves, often inside the industry they now sell to. We're happy to invest before there's much traction, and after the round closes we help with hiring, go-to-market and the next raise.
Where we look
01
AI & machine learning
Companies whose product is built on AI models, and the tools and data those products depend on.

02
Health
Care delivery and diagnostics, including telemedicine and mental health.

03
B2B software
Software that businesses and institutions, schools included, use to run their day-to-day work.

What we look for
You don't need all four. Most companies we back are strong on two and working on the rest.
- 1You know the customer
You've worked in the industry or on the problem long enough to know who pays and why.
- 2People are using it
At pre-seed, a live product and early users. At seed, revenue growing month on month.
- 3A clear use for the money
How much you're raising, and where it gets the company by the next round.
- 4Based in France
Usually a French SAS, with most of the team here.
What you get besides money
One partner runs your process from the first call to close and keeps working with you after it. Our partners have built companies themselves, so the help is practical.
Hiring
We help write the role, find candidates through people we know, and sit in on senior interviews if you want.
Pricing and go-to-market
Working sessions on who to sell to first, what to charge and how to reach those buyers.
Your next raise
Deck reviews, practice pitches and introductions to follow-on investors we know personally.
Customers
Introductions to companies in our network that could buy what you sell.
The full list is on Founder help.

You won't be building alone

Questions founders ask us
What stage do you invest at?
Pre-seed and seed. Our first cheque is usually €200K to €500K at pre-seed and €1M to €3M at seed.
Which sectors do you cover?
AI and machine learning, health, and B2B software. If your company sits between these, send it anyway.
Where do your companies need to be based?
France. We invest in French companies, usually incorporated as an SAS, with most of the team based in France.
Do you lead rounds?
We lead or co-lead pre-seed rounds and join seed rounds alongside a lead investor. When we lead, we usually take a board seat.
Do I need a warm introduction?
No. Use the form below. A partner reads every pitch.
How long until I hear back?
We reply to every pitch within two weeks. If we want to go further, one partner runs the process from the first call to a decision, which takes a few weeks.
Do you help with AI and cloud costs?
Yes. Every company we back gets help applying for startup credits from OpenAI, Anthropic, Microsoft Azure, AWS and Google Cloud.
