What they're building
A penetration test usually captures a system at one moment. New deployments and changes can introduce weaknesses after the audit is finished.
Fleuret uses AI agents to test applications and infrastructure as they change. Its platform helps teams identify exploitable weaknesses, prioritise fixes and verify that the problems have been resolved.
The round
RAISE Ventures led the €4 million pre-seed, with participation from Auriga Cyber Ventures, Wind Capital, Better Angle and cybersecurity angels. The funding supports new hires in AI, engineering and security, alongside the continued development of the platform.
