Hi, I'm Izzy

A doctor who fell in love with building things, and helping others do the same.

I trained as a medical doctor and studied at Cambridge, then co-founded a software company and grew a community of a million and counting along the way. What ties it together is a belief that you can design a life that's both ambitious and gentle.

This is where I share what I'm learning: about health, growth, and building a business on your own terms.
