Diby

Agentic AI fitness coach, digital twin of a real human coach.

More clients. Less work. Higher margins.

Stay solo. Scale like a team.

[Stjepan Buljat @sbuljat]

After a decade and $80M+ ARR at Cognism, I left the company last year in August. 

Building a category-defining sales intelligence company from zero was the hardest and most rewarding job of my career. 

If it were anyone else, I'd tell them to take a real break, advise a few founders, and call it a career. 

Easier advice to give than to take when you are an entrepreneur. 

For the past nine months, Mario Vidović, @lucasdeats and I have been heads-down in sports tech, pulling apart everything broken about the software fitness coaches are forced to run their business on. 

I've trained with the same personal trainer for years. He's brilliant at coaching.
He also runs his own marketing, accounting, and CRM - time he could be spending coaching. 
He's not the exception. 

This is why I'm proud to step into a new role as Co-founder & CEO at @getdiby  

Diby is the AI-native operating system for fitness coaches. 
It handles programs, clients, scheduling, payments, retention, and communication. 

Built so a great coach can stay one, instead of slowly becoming an accidental operations manager. 

Founding Coach cohort opens this May. If you know a coach who'd want one of the first seats, send me a DM.
