Kyan is 21, still in college, and shipped his first app ever 5 months ago. Now ToneAdapt has 100K+ users and pulls $25K/mo.
His stack is dead simple:
Cursor + Claude Code for all the code (vibe-coded, zero lines written by hand)
Supabase for database
Vercel for hosting + backend API routes
Stripe for payments on the web app
RevenueCat for mobile subscriptions
Superwall for paywalls + A/B testing
OpenAI API + Tavily web search API
Mailgun for emails
Swift native for the iOS app
The website did $11.5K and the mobile app did $14K in the last 4 weeks alone.
