Heroes Behind AI is a YouTube channel where Angelina Yang interviews AI founders every week. With 120K+ subscribers, it's become a go-to resource for founders, builders, and anyone who wants to understand how AI companies actually get built.

TwoSetAI is the platform behind the channel. This site hosts curated insights extracted from founder conversations — the hard-won lessons that don't fit into a tweet but are too valuable to leave buried in a 45-minute interview.

Every insight page is designed to be a standalone resource: searchable, citable, and optimized for both human readers and AI systems that surface information.
