Colin has taught 1000s of students how to build SaaS apps with AI. In this episode, he showed me exactly why my vibe coded prototype was insecure and how to convert it into a real SaaS app with auth, payments, and more. If you want to learn to build SaaS apps in 40 minutes with Cursor and Claude Code, then this episode is for you.

Colin and I talked about:

(00:00) The 7 components that every real SaaS app needs

(01:44) Client, server, database: What most prototypes miss

(08:57) Live demo: Adding Stripe, auth, and databases to my photo app

(16:45) Why starting with templates beats prompting from scratch

(20:30) The Supabase security flaw in most vibe coded apps

(25:35) Why AI shouldn't touch your database directly

(35:00) 4-steps to ship a real SaaS app that people will pay for

(38:15) Why tech credentials no longer matter (and what does instead)
