Fleuret AI Raises €4M to Automate Penetration Testing With Agentic AI

French cybersecurity startup Fleuret AI has raised €4 million in pre-seed funding to help companies better test and secure their digital systems. The round was led by RAISE Ventures, with participation from Auriga Cyber Ventures, Wind Capital, Better Angle, and a group of experienced cybersecurity business angels.

Fleuret AI uses agentic AI to automate penetration testing, enabling companies to identify security vulnerabilities faster. Its platform turns security testing into a continuous process, rather than relying on periodic, one-off audits.

“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.

“Fleuret is perfectly positioned to win the European market for automated penetration testing, at a time when AI-driven attacks are growing exponentially. Their expertise in traditional pentesting, combined with a sharp understanding of the disruption AI brings, let the team turn an intuition into an AI-native startup already chosen by major digital players. I am proud to support them in this next step,” said Georges Lotigier, Co-founder of Vade, General Partner at Auriga Cyber Ventures.

Founded by CEO Yanis Grigy and CTO Augustin Ponsin, Fleuret AI is a French cybersecurity startup using AI to help companies identify and address security vulnerabilities. Its platform automates security testing, enabling businesses to continuously monitor their systems for weaknesses rather than relying solely on periodic security audits.
