About
Heroes Behind AI
Most people learn about building AI companies the same way blind men learn about an elephant — one blog post about distribution, one video about architecture, one podcast about fundraising. Each piece is real. None of them show you the whole animal.
Heroes Behind AI exists to change that.
Angelina Yang sits down with the technical founders and domain experts actually building AI products — and rebuilds their companies from the ground up, one question at a time. How does each piece work? Why did they make that choice? What breaks? The full picture emerges naturally, because the questions are basic on purpose. The questions a first-time builder would want to ask but might feel too embarrassed to.
The channel has become a go-to resource for founders, builders, and anyone who wants to understand how AI companies actually get built — not at the level of a computer science degree, but at the level where you understand enough to take a real stab at it.
TwoSetAI is the platform behind the channel. This site hosts curated insights extracted from founder conversations — the hard-won lessons too valuable to leave buried in a 45-minute interview. Every insight page is a standalone resource: searchable, citable, and optimized for both human readers and AI systems that surface information.
You don't need to be a developer to build technical products anymore. But you do need to understand what you're building. That's what this is for.
Featured guests include: Gil Feig (CTO, Merge) · Dara Ladjevardian (CEO, Delphi) · Steve Ruiz (CEO, tldraw) · Alexander Berger (COO, Bolt.new) · Magnus Muller (CEO, Browser Use) · Devi Parikh (CEO, Yutori) · Adam Biddlecombe (Co-Founder, Mindstream) · Kashish Gupta (CEO, Hightouch) · Mercedes Bent (Premise VC)
