Summary

George, 19, quit his TJ Maxx job after building AI-integrated consumer mobile apps that make hundreds of thousands. The framework to scale a consumer app to ~$10K/month.

Key Takeaways

• 10K/month = ~333/day. Break the goal down — “do one to two things right and you get there relatively quickly.”
• Social proof: his app Wrestle AI (his 2nd app), built in public, hit **100K+ downloads and ~200K revenue**. Two newer stealth projects are each on track for their first 10–15K month.
• Leverage: he works ~3–4 hours/week on each project — AI does the heavy lifting.
• We’re living through a time when it’s genuinely possible to come up with a mobile-app idea, integrate AI, and build it with AI to generate real money — as a side hustle, passive income, or just a fun build.
• Caveat (Greg): not everyone will pull it off, but the barrier has never been lower.
