Agentic AI penetration testing, hosted in Europe
Fleuret (Fleuret AI) is a Paris-based startup automating penetration testing with agentic AI. Its agents map a company's web apps, APIs and infrastructure, attempt to exploit what they find, and attach a replayable proof of concept to every reported finding, with re-testing and compliance-mapped reports for frameworks such as NIS2, DORA and ISO 27001. The platform runs on European infrastructure. On 5 October 2026 it announced a €4M pre-seed round led by RAISE Ventures with Auriga Cyber Ventures, Wind Capital and Better Angle. Co-founders are Yanis Grigy (CEO) and Augustin Ponsin; the company says it has around ten people and customers including Brevo, Stoïk and Yogosha.
