Build a full SaaS with 4 AI agents. No Human code | The Multi-Agent SaaS Playbook

Hey Product Hunt! 👋 We are the team at REBORN Technologies Ltd and we are excited to share The Multi-Agent SaaS Playbook today. A few months ago we asked a simple question: what if the entire engineering team was AI? Not AI-assisted. Not AI autocomplete. Four fully autonomous Claude Code agents, each owning a distinct layer of the stack, working in parallel. Sofia owned the frontend — 33 stories. Lucas owned the backend — 39 stories. Aria owned the AI layer — 9 stories. Marco owned QA and security — 8 stories. They communicated through Git commits, file locks, and a shared PROGRESS.md. They never talked to each other directly. 96 stories later — the product was live in production. This playbook is the complete documentation of that process. Every template, every script, every failure, every fix. We are here all day to answer questions about: → How we structured the agent roles → What CLAUDE.md files actually look like → How we handled rate limits and conflicts → The communication patterns between agents → How to start your first multi-agent project Ask us anything. 🤖
