Even the toughest problem can be reduced to a simple estimation question. Enrico Fermi won a Nobel prize doing it. Google expects top job candidates to do it. Can you?

Welcome to Fermi Club.

Every week, we challenge you, the community, with carefully-curated puzzles to teach you the Fermi framework for making tough problems easier to solve.

Sign up now so you don’t miss out on:

  • dunking on trick questions in job interviews

  • coming up with the next big startup idea

  • solving tough problems that come your way


Even the toughest problems can be simplified to a back-of-the-envelope calculation.

Dr. Enrico Fermi was a bona fide genius – he won the Nobel prize, invented the first nuclear reactor, the whole shebang. His secret? Simplifying complex problems to back-of-the-envelope calculations.

You can train yourself to do the same using unique questions that we call Fermi puzzles. Google uses them to hire top candidates. World-class thinkers use them to get smarter. With Fermi Club, you can access them, too.

We send you the best Fermi puzzles & teach you Fermi thinking so you can learn to solve even the toughest problems on the back of an envelope.
