Prognozza is an AI sports prediction app covering football, basketball, and tennis with a freemium model centered on daily picks and head-to-head duels against the AI. The founder claims 50k+ signups from a v1 launch 9 months ago and has now shipped a ground-up v2 rebuild solo, but corroborating growth signals and revenue evidence remain sparse.

One insight: The founder's claim of 50k signups lacks independent verification (no app store rankings, social proof, or revenue data visible), and detection velocity is zero across public sources—suggesting either organic fatigue post-launch or overstated initial traction.
