What they did

He used Cursor for the React frontend and Node backend and Claude for complex logic like PDFs and cron jobs, launched an ugly v1 on Product Hunt, and added features users asked for.

How it went

He reports 100 paying users and about $2k MRR; 20 signups in launch week, about half converted after a trial.

Worth knowing

His advice: do not let AI overcomplicate things; it is a tool, not a brain.
