I Left College to Build This Niche App (Now I Make $20K/Month)
Ethan, a 19-year-old college dropout and former national wrestling champion, built CutCoach, an iOS app that gives combat-sport athletes a science-based weight-cut plan, with Cursor and ChatGPT. After a failed coach-first beta with his wrestling club he pivoted to athlete-direct plans and launched in September at the start of wrestling season. Growth came from small organic posts that converted high-intent viewers, then DMing small TikTok/Instagram creators, then running those creator videos as paid ads. Claims $20K in a month; ~39K downloads.
