About

Hey - I’m Casey Juanxi Li.

I am a software engineer and data scientist with a machine learning background. I write and I self-teach psychology.

The above are all means to an end: I like understanding problems, and building useful tools to solve them.

I write a newsletter about tech, VC, and startup hubris at But First, Entrepreneurs. It’s based loosely on my experience at EF. I’ve been told it’s a little edgy 👀 but entertaining, and serious at times.

If you like to categorize people based on:

  • Beliefs:
    • I like software as a medium because it has so few gatekeepers.
    • I like open, permissionless markets that directly connect consumers and producers, while maintaining an open record for reputation. I think this is the best way to encourage meritocracy and reduce nonsense.
    • It’s hard to construct such markets, so we rely on relationships instead to provide trust and information.
  • Something else? Now I’m curious. Feel free to drop a message: casey(at)cs.toronto.edu


I am Canadian and currently live in Toronto. I’m in London (UK) quite alot too.
