Hi, I'm CJ.

Chinese AI Founder. Reed College Computer Science dropout. Backed by Baidu, YC China, and Fenghe Capital. Product acquired — starting over.

Why do this?

I want to show you the real thing.

I watched Undercover Billionaire. Inspiring. But I want to do an AI entrepreneur's version — an experiment that actually fits the world we're in today. Anyone can watch, learn, and replicate. Not a highlight reel. The full picture — including the hard parts. Because if you're building something and it feels painful and confusing, that's normal.

“There is only one heroism in the world: to see life as it is, and to love it. — Romain Rolland”

Undercover Billionaire — Discovery

Inspired by Undercover Billionaire

Discovery Channel — but this one is real.
