About

I'm Brian Casel, a full stack product builder who's gone all-in on AI-first development. Building with AI isn't just hypeβ€”it's leverage. It's transforming how we create software products, and I'm here to show you why mastering these techniques now will define who wins in the next decade. Each week, I share: - What's actually changing in our craft (not just what's trending) - Practical AI building techniques you can use today - Real lessons from shipping AI-powered products This isn't about chasing the latest models or buzzwords. It's about understanding how AI fundamentally changes what's possible for builders. If you're a developer, designer, or product builder who wants to stay ahead of the curve without getting lost in the noise, you're in the right place.
