Fleuret AI has raised €4 million in a pre-seed round to build a platform for continuous AI-assisted penetration testing. The French startup says the capital will fund product development and recruitment across AI, software engineering and offensive cybersecurity. RAISE Ventures led the round, which also included Auriga Cyber Ventures and other participants.
What does the platform do?
Penetration testing is a controlled effort to find security weaknesses and check whether they can be exploited. Fleuret AI says its platform is designed to move this work beyond an audit that captures a system at one moment. The company argues that later changes to a system can change its attack surface, meaning the parts exposed to possible attack.
Its approach has five parts: mapping exposed systems, identifying vulnerabilities, demonstrating exploitability, helping teams fix issues and checking that fixes have worked. The company says this process is intended to connect testing with follow-up action. The source material does not set out a schedule for checks or explain what customer approval is required before exploitation attempts.
How are Emile and Champollion used?
Fleuret AI says two AI agents, Emile and Champollion, map a company's environment and examine its applications, APIs and infrastructure. They then attempt to exploit vulnerabilities found during that work. Each finding includes proof of compromise, which is meant to demonstrate whether the weakness can be exploited.
The platform is also intended to keep monitoring the attack surface and initiate further tests as systems change. Fleuret AI is developing additional tools to rank vulnerabilities by exploitability, connect with technical teams' existing tools, retest systems automatically and report whether issues have been fixed. The accounts do not provide a release date for these features or independent results from their use.
Who founded the company, and what will the money support?
Yanis Grigy, the company's CEO, and Augustin Ponsin, its CTO, founded Fleuret AI in 2026. The company says it will use the €4 million to accelerate platform development and expand its team with people working in AI, software engineering and offensive cybersecurity. It has not disclosed a hiring target, a breakdown of spending or a valuation.
RAISE Ventures led the financing, and Auriga Cyber Ventures participated. The source material also names Wind, Better Angle and cybersecurity business angels among participants; another account calls the investor Wind Capital. It gives no amounts for individual investors and no further terms for the pre-seed round.
Why does Fleuret AI focus on ongoing tests?
The company says organisations update their systems while conventional penetration testing often remains a one-off exercise. That creates a gap between the system assessed and the system in use after later deployments. Fleuret AI presents ongoing monitoring and repeat tests as a way to address that gap, but the source material does not establish how well its approach performs in practice.
Fleuret AI is targeting the European market and says its agents operate from Europe on European infrastructure. It connects that setup with sovereignty needs in highly regulated sectors and says the platform is meant to make offensive cybersecurity more accessible to organisations unable to run regular tests. No specific regulatory approval, customer deployment or independent evaluation is reported.
The funding announcement establishes the round size, lead investor and intended uses of proceeds, while leaving investment terms undisclosed. The company says its next work will focus on hiring and platform development, without giving milestones or timing. Future updates would clarify when the added testing and remediation features reach customers and what results they produce.
