Tristan de Halleux

Physics + Computer Science at Columbia.
I build across software, AI systems, and increasingly physical systems.

Originally Belgian, I grew up in San Francisco, was born in London, and spent a few years in Armenia before moving to New York.

I tend to get interested in things that sit between software and the physical world: AI infrastructure, networks, industrial systems, physics, and products that change how people interact. I’ve founded and shut down a startup, built products for students at Columbia, and worked on AI infrastructure and optical networking in Palo Alto.

I try to complete one ambitious project per month, especially ones that force me to learn something outside my lane.

Outside of that, I ski, sail, run, cycle, am getting back into tennis, and make music.

Explore my projects, or ask me something.
