AI-native operating system for solo founders. One person. Five-person output.
LeanOS is a composition of independent modules. Each runs one business function end to end. They compose through the filesystem.
| Module | Function | Price |
|---|---|---|
| StrategyOS | Research, hypothesis, gap analysis | Free - MIT |
| RevenueOS | Pipeline, outreach, nurture, retention | Paid |
| EngineeringOS | Spec → build → verify → deploy | Paid |
| WriterOS | Long-form content from artifacts | Paid |
| StyleOS | Brand inputs → production design system | Paid |
| FoundryOS | Specs and builds the modules above | Paid |
Each module: own repo, own agents, own skills. No shared runtime. Plain markdown, no compiled code, no hidden prompts. cat any file.
StrategyOS is the entry point. It produces the Hypothesis Register and Gap Register.
Downstream modules consume it:
- RevenueOS reads gaps → builds outreach
- EngineeringOS reads validated hypotheses → builds product
- StyleOS reads positioning → builds brand
- WriterOS reads everything → produces narrative
FoundryOS sits underneath. 6 agents, 27 skills. You describe a system, it specs construction, builds agents and skills, wires infrastructure, assembles the orchestrator. Every module above was built with FoundryOS. Including FoundryOS.
Decide before you build. Build what survives validation. Sell what's been built.
- Claude Code as runtime
- Markdown skills, no compiled code
- Filesystem as message bus
- Plain text artifacts, no vendor lock-in
Begin with StrategyOS. Free. MIT. Decides what to build before you spend cycles building.
