Jack Luo

I enjoy operating, investing, and solving deep problems with smart people. I live between Toronto and New York and run Lindy Ventures, where we invest our own capital into the above.

Before that I founded Modern Menopause and grew it to become Canada's largest women's health virtual care platform.

I trained as a physician and went to McGill for my MD but never practiced and fell in love with engineering instead. In a past life, I started my career drawing charts at Plotly and then covering quantamental strats and unusual options flow for a $10B tiger cub.

Many of my closest friends today started out as internet friends, so please reach out: jack [at] lindyventures [dot] com or on X.

Beliefs

  • You can just do things
  • We know less than we think
  • The efficient market is mostly a lie (or at least: living life as if it were true is a dangerous way to clip your upside. All serendipity happens when it's wrong. Perhaps different in the markets). Not everything is priced in
  • Sometimes, serendipity and tail outcomes are all that matters
  • Small teams are strictly better than large teams. Multi-layer orgs should not be a thing anymore with AI
  • When working with people, choose values over "incentives" every time
  • Speed is a moat, maybe the only real moat outside of network effects
  • You can do great things by taking simple ideas and treating them very seriously (obsessively)
  • Systematic can take all shapes, but every single great discretionary investor is a whale hunter. They win via table selection and knowing to sit out 98% of the time
  • Margin of safety is a real thing, but only on the way down
  • Talent matters more than experience. Gut matters more than data. The delta between the 2 is adverse selection
  • Directionally, I think most people care too much about day to day mundane stuff and way too little about the 4-5 decisions that really matter (school, partner, city, first job, etc). There are only so many f**s you can give, ration them wisely
