Founden turns a plain-language description into a real, running company: the website, the app with sign-in, back office, payments, email and its own domain, built and published by an AI builder (Claude Code or Codex). Switch on autopilot and the same AI keeps developing it: it ships improvements, answers company email and works on growth. Build in the browser or the macOS desktop app on your own AI plan. Free to start with 200 credits; paid plans from $29 a month.
