Founder is a free, MIT-licensed set of eleven Claude skills that test a business before you launch it. No signup, no API key, nothing to connect. Each skill writes into a founder/ folder in your project, and the next one reads it, so they work as one team.

Install it

  1. Easiest: paste https://github.com/Jakeschincariol/founder-skill into Claude and say: install skill
  2. Or in Claude Code: /plugin marketplace add Jakeschincariol/founder-skill, then /plugin install founder-skill@founder-skill
  3. Or copy the folders: git clone the repo, then cp -r founder-skill/skills/founder-* ~/.claude/skills/
  4. The four helper tools need Python 3.8 or newer. Nothing to pip install, and they never touch the network.
