Summary
🤩
Rockstar🎓
Top SchoolJean-Baptiste Kempf is a technology entrepreneur and free-software advocate with 19 years of experience, best known as President of VideoLAN and a lead developer of the VLC media player. He now leads Kyber as Founder & CEO building patent-pending ultra-low-latency remote-control and streaming infrastructure, while also serving as CTO at Scaleway and founding several video-focused startups. An active open-source engineer, his contributions to VLC and libnfs emphasize cross-platform compilation fixes and low-level bug resolution, reflecting deep systems and codec expertise (x264, dav1d, FFmpeg). His early work writing assembly for Itanium and co-authoring research on quantum computing and solar panels gives him unusual scientific breadth that informs his work on AI/HPC clusters and real-time video systems.
