Founden is the engine for autonomous software. Describe the first version and it goes live. Leave it running and it keeps developing itself. Founden turns a plain-language description into a real, running company: the website, the app with sign-in, its 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. Free to start with 200 credits; paid plans from $29 a month.
