SUMMARY

Fleuret AI, a French cybersecurity startup, has raised €4 million in pre-seed funding.
The round was led by RAISE Ventures, with participation from Auriga Cyber Ventures, Wind Capital, Better Angle, and cybersecurity business angels.
Fleuret AI was founded by Yanis Grigy (CEO) and Augustin Ponsin (CTO).

Fleuret AI uses agentic AI to automate penetration testing, helping companies find security weaknesses more quickly. Its platform is designed to make security testing a continuous process rather than a one-time audit.

“We do not simply want to automate penetration testing as it exists today. Our ambition is to build the offensive security layer that will keep companies secure all year round, whatever their size. This round gives us the means to accelerate that vision and to build a platform designed for enterprise environments from day one.” said Yanis Grigy, CEO and co-founder of Fleuret AI.

“AI has changed the nature of cyberattacks by putting powerful tools within everyone's reach, often for free. Organisations have to test their security against every attack technique, including the newest. Fleuret built its platform to evolve continuously and stay a step ahead of attackers, with a team that puts AI to work for deep offensive expertise. We are convinced Fleuret can become the reference in offensive security in Europe,” said Thibaut Schlaeppi, Co-Head, RAISE Ventures.

I am proud to support them in this next step,” said Georges Lotigier, Co-founder of Vade, General Partner at Auriga Cyber Ventures.
