Anthropic's AI-native founder's playbook: four stages, exit criteria, and prompts you can copy straight out
The 36-page official playbook breaks down the graduation criteria, common traps, and matching Claude prompts for each of four stages — ready to copy and use
⚑Where we stand: this is Anthropic's own founder's handbook, and the toolkit it recommends throughout — Claude, Claude Code, Claude Cowork — is entirely its own product line. The efficiency numbers in the closing case studies (the 66% improvement, the 1.5 million users) are self-reported by the companies involved. The four-stage framework and exit criteria themselves stand on their own and are worth borrowing independently.
