Company OS Starter Kit

Build your own Company OS with Claude Code.

We're building an AI-native GTM services company. We scaled to 20 people in under 9 months. Bootstrapped. Claude Code has become a huge part of how we operate.

This is the starter kit for building the same kind of system. The folder structure, the skills, the safety hooks, and the setup guide we wish we had when we started.

Built by Dan Rosenthal at workflows.io. Full setup guide on Notion.

What is a Company OS?

A Company OS is a set of files (primarily markdown) that gives your AI persistent knowledge about your business. Your tools, your processes, your rules, your voice, your team. Instead of re-explaining your business every conversation, Claude starts every session already knowing who you are.

At the center is CLAUDE.md, the one file Claude reads on load. It points to everything else: company context, skills, tool connections, safety rules. Not a prompt you paste. An operating system that compounds the more you use it.

Quick Start

Open your project in Claude Code and say:

Claude will:

- Ask about your company, tools, team, and processes
- Fill in every {{placeholder}} based on your answers
- Adapt the structure to your business type
- Suggest your first custom skill when done

No manual markdown editing required.

How hooks work

  • Hooks are shell commands Claude Code runs at fixed points: before or after a tool call, when you submit a prompt, when Claude stops, on notifications and at session start.
  • They are set in the hooks section of ~/.claude/settings.json (or .claude/settings.json for a project), or come bundled in a plugin.
  • A hook can block a tool call, add context, or run a formatter or test. Read the scripts before you install them: they run on your machine with your permissions.
