This is f**king gold doc.. I found Official Anthropic doc (June '26, 36 pages). FREE - "The Founder's Playbook: straight roadmap for AI-native startups". 4 stages. Clean 1/ Idea - validate hard before code "Expense reporting is observation. Finance managers losing four hours to broken integrations is a testable hypothesis" Exactly. Specific beats vague 2/ MVP - architecture first (CLAUDE.md), then agentic build. Security review before users touch anything 3/ Launch - Claude Cowork handles feedback loops, CRM, scheduling. Real PMF: Sean Ellis test (40% very disappointed = signal), effort shift 4/ Scale - hand off without losing your head. Bottleneck map before growing Founder = orchestrator. They don't promise autopilot - you direct agents, they don't replace you Quick exercises throughout (session templates, false positive definitions). Worth it Read it. I'm not exaggerating
