Our app flopped, so we rebuilt it and hit $30K MRR
Eyal and Yahli Hazan launched PropGPT, a sports betting analytics app, in the 2024 NFL season with influencer marketing: 45% install-to-trial but 13% trial-to-paid, stuck at $1-2K MRR. Realizing users wanted ready-made picks, they paused marketing and rebuilt for 4 months. After an April 15 relaunch and an NBA Playoffs push, conversion to paid passed 50% and MRR peaked at $40K 2.5 months later; now ~$30K/month, 40K+ downloads, 3,000+ payers, ~$3.30 per download, ~50% margins.
