Founders

Alexander Schiff

Founder

Co-Founder and CEO, Channel3 (S25). I started coding at 9 and launched my first company at 12. Studied Computer Science and Psychology at Duke, where George (Channel3 CTO) and I worked together for years and even founded a startup together. Worked as a PM at Microsoft, then reneged my return offer to lead AI projects at Studio.com, where I discovered this pain point and set out to solve it. Fun fact: My twin brother and I auditioned for MasterChef Junior.

Co-Founder and CTO, Channel3 (S25). Before Channel3, I worked as a software engineer at Palantir for a couple of years. There, I tackled hard security and data problems, and I built some cool stuff. I graduated from Duke with a B.S. in CS. During my senior year, I started my first company with Alex (Channel3 CEO). Fun fact: I'm also a published astronomer (twice!)
