About

I'm Justin Mares. I build companies at the intersection of health and technology.

Currently I'm the co-founder and CEO of TrueMed, which enables customers to use HSA and FSA funds for eligible health purchases. Previously I co-founded Kettle & Fire, the leading bone broth brand, and co-authored Traction, a book on startup growth.

I write about health, startups, and ideas I find interesting. You can find me on X/Twitter or subscribe to my Substack.
