LeanOS is an open-source operating system for running a startup on Claude Skills. It runs real startup operations in one repo (no scattered docs), including: - Product discovery, system design, and roadmap execution - Marketing strategy, content generation, and campaign ops - Sales enablement, outreach workflows, and pipeline logic - Operating metrics, reporting, and feedback loops On the engineering side, LeanOS: - Orchestrates non-deterministic LLM work imperatively (agents + skills) - Validates AI output after every step, with retry-and-feedback loops - Enforces strict quality gates before advancing phases - Separates AI generation from deterministic, verified artifacts All workflows, docs, specs, and validations live in one repository, with a clear boundary between unreliable AI execution and structured, correct outputs. Built for tech-savvy founders comfortable working in VS Code (or similar IDEs) who want AI to run work, not just generate text. Repo: https://github.com/BellaBe/lean-os
