How a non-coder built a wrestling app to $17K/month

George Lamperis was 18, a freshman in college, and had never written a line of code. Six months later, his app WrestleAI was generating over $17,000 per month. He didn't learn to program. He learned to prompt.

The app is an AI wrestling coach: users submit match videos, and the AI breaks down what they did right, what they did wrong, and gives drills to improve. Pricing is $9.99 monthly or $59.99 yearly. Since launching in September, the app has accumulated over 17,000 downloads and more than two million social media impressions.

The failure that shaped the approach

Before WrestleAI, George had already tried building an app. At 15, he and a friend saved money and went all-in on a social self-improvement app. They built hype on social media, got 10,000 followers waiting for launch, and hired three development agencies. None delivered. It took 18 months to release, by which point the hype had died. They lost everything. George ended up working at TJ Maxx.

That failure became his operating system. "I just have to be absolutely relentless on how I attack creating things," he said. The experience taught him that hiring developers to execute a vision you can't build yourself is a slow, expensive gamble. He needed a way to build directly.
