Summary
🤩
Rockstar🎓
Top SchoolTristan Leteurtre is a seasoned founder and software engineer with 17 years of experience building and scaling fintech and telecom software businesses, currently leading Mooncard and Lune Ventures. He combines executive leadership—having grown Anevia to a public company role—with hands-on engineering roots from founding work on VLC/VideoLAN and deep involvement in media codecs and streaming. Tristan is a pragmatic backend systems expert who has contributed robustness and security fixes to high-profile open-source projects like VLC, mozjpeg, rav1e and Janus WebRTC, and helped harden OSS-Fuzz build infrastructure. His work spans low-level audio/video codecs, real-time streaming protocols (RTSP/WebRTC), and production-grade build/fuzzing pipelines, reflecting an uncommon mix of product, operations and low-level C/Go/Rust skills. Based in Montreal with an education from CentraleSupélec and Cambridge, he pairs scientific rigor with entrepreneurial grit and a track record of shipping resilient, widely deployed software. A less obvious strength: he repeatedly focuses on simplifying brittle codepaths and preventing crashes, turning obscure stability fixes into large reliability wins.
