01 / Founding

“I wanted one done my way.”

Why I built Exypnos

I built Exypnos out of frustration with today's frontier AI chat providers. I wanted one done my way. I was also inspired by someone I met whose work ethic pushed me to create something of my own.

What I do

I split my time between writing code, running meetings, and handling the company's business dealings.
