Today we’re sharing news we never wanted to have to write.
With heavy hearts, we announce that Felix “FX” Lindner—a cherished friend, and the founder and owner of Recurity Labs—passed away on 2026-03-01.
For many of us, Felix wasn’t only the person who built this company—he was the person who shaped how we think and how we work: with curiosity, discipline, and the kind of honesty that respects both the challenge and the people behind it. Many of you knew him personally and valued him as a collaborator, a mentor, a teacher, a sparring partner, or a familiar face from projects and the wider security community.
Inside Recurity Labs, Felix was a constant reminder that security is ultimately about people. He cared deeply about doing things properly—technically, ethically, and humanly. He set the tone for Recurity Labs as a place that values real-world impact over hype, careful analysis over shortcuts, and clear words over vague promises.
If you’re feeling the weight of this message, you’re not alone.
The path ahead
Recurity Labs continues—not because we want to rush past the grief, and not because “we must move on,” but because this is what Felix expressly wanted: that we carry Recurity Labs forward with professionalism, integrity, rigor, and care. We will keep doing the kind of security work that FX rooted into Recurity Labs—deep technical excellence, practical outcomes, and respectful, long-term relationships.
Thank you
We’re grateful for the trust so many of you placed in Felix and in Recurity Labs over the years.
