Fleuret AI Raises €4M for Agentic Pentesting
Paris-based Fleuret AI raised €4M to automate penetration testing with AI agents.

Cybersecurity testing is shifting from occasional audits toward continuous, AI-driven validation.
What happened
Paris-based Fleuret AI raised a €4M pre-seed round led by RAISE Ventures, with participation from Auriga Cyber Ventures, Wind Capital, Better Angle and cybersecurity angels from companies including Stoïk, GitGuardian, Vade and Almond.
The company is building agentic AI systems that automate penetration testing, helping organisations identify weaknesses more continuously.
Why it matters
Traditional penetration testing can be slow, expensive and periodic. But software changes constantly, and attackers are increasingly using automation themselves.
Fleuret’s approach fits a broader trend: defensive security tools are becoming more agentic so they can test systems continuously and surface exploitable chains before attackers do.
The bigger picture
AI is changing both sides of cybersecurity. As attackers automate reconnaissance and exploitation, defenders need tools that can continuously simulate realistic attack paths, prioritise risk and validate whether fixes actually work.
