French cybersecurity startup Fleuret AI has raised €4 million in a pre-seed funding round to develop its platform for automating penetration testing using agentic AI. The round was led by RAISE Ventures, with participation from Auriga Cyber Ventures, Wind, Better Angle and business angels from the cybersecurity sector.
Founded by Yanis Grigy (CEO) and Augustin Ponsin (CTO), Fleuret AI is developing a platform designed to turn penetration testing from a one-off audit into a continuous security process. The platform is structured around five areas: mapping exposed systems, identifying vulnerabilities, demonstrating whether they can be exploited, supporting remediation, and verifying that identified issues have been resolved.
The company is targeting a gap between the way information systems evolve and how penetration testing is traditionally conducted. While companies continuously update their systems, penetration tests are typically carried out as one-off audits, providing a snapshot of security at a particular point in time. Subsequent deployments can alter the attack surface shortly after an assessment has been completed.
To address this gap, Fleuret AI is automating parts of a penetration tester's work through two AI agents, Emile and Champollion. The agents map a company's environment, explore its applications, APIs and infrastructure, and attempt to exploit identified vulnerabilities. Each vulnerability is accompanied by proof of compromise intended to demonstrate whether it can be exploited.
The platform then continuously monitors the attack surface and can initiate additional tests as a company's systems change. Fleuret AI is also developing tools to support the remediation process, including prioritising vulnerabilities based on exploitability, integrating with technical teams' existing tools, automatically re-testing systems and generating reports confirming whether vulnerabilities have been fixed.
We don't just want to automate pentesting as it exists today. Our ambition is to build the offensive cybersecurity layer that will allow companies, whatever their size, to stay secure all year round. This funding gives us the means to accelerate that vision and build a platform designed from the ground up for enterprise environments,
said Yanis Grigy, CEO and co-founder of Fleuret AI.
The company is targeting the European market and aims to make offensive cybersecurity accessible to companies that may not have the resources to conduct regular penetration tests. Its AI agents are operated from Europe on European infrastructure, which the company says is intended to address sovereignty requirements, particularly in highly regulated sectors.
The new funding will be used to expand Fleuret AI's team with specialists in AI, software development and offensive cybersecurity, as well as accelerate development of the platform.
