In this episode of The Everyday Founder, James sits down with Tomas Helgaš, founder and CEO of Sutro — the AI platform that turns a single text prompt into a full production-ready app.
Before Sutro, Tomas worked at Facebook (helping power the “People You May Know” feature), then went on to build and sell Sphere to Twitter after raising $30M.
Now, he’s back for round two — building Sutro to change the way the world builds software. This conversation dives into the mindset, mission, and mechanics behind one of the most fascinating builders in AI today.
We discuss:
- Why Tomas left his dream job at Facebook to start Sphere
- How he built a company that became the foundation for X (Twitter) Communities
- The early days of Sutro and building secure, production-grade AI tools
- The tradeoff between shipping fast vs. building safely
- Co-founders, hiring mistakes, and second-time founder lessons
- How AI will reshape how software is built — and why security is the next big frontier
