His fantasy sports app has real paying subscribers, and a data API side business grew out of it

He has been building a fantasy sports app with AI since June. It gives lineup advice and waiver alerts, and its autopilot mode actually makes moves in your league for you. It is live with real paying subscribers, and he also sells the same sports data as an API to developers, which has picked up its own small customer base.

How it works

Build the app solo with AI
Add advice, waiver alerts and an autopilot that executes league moves
Launch with real Stripe billing
Sell the same data feeds as an API to developers

Why it’s worth knowing

The side business was not the app, it was the data underneath the app, sold twice.
