Hi, I'm Andrew

I founded Cover, a restaurant payments startup in New York, raised $7M, and got acquired.

Before that, I dropped out of high school, studied computer science at Carnegie Mellon, and wrote engine code for PlayStation games at Naughty Dog.

Now I live in Breckenridge, Colorado — where I snowboard, make music, invest in startups, and build things with AI.
