Market Size

TAM/SAM/SOM with real-world data, not made-up multiples. Bottom-up first — count real customers and multiply by price. Top-down is a sanity check, not the primary method.

Input Dependencies

Read from ./founder-outputs/ before proceeding:

• pressure-test-output.md — demand evidence, workaround details
• customer-archetype-output.md — specific customer definition, company size, industry

If customer-archetype-output.md is missing, the market sizing will be generic. Recommend the user run /customer-archetype first.

Frameworks

• Lean Analytics (Croll & Yoskovitz) — one metric that matters. Realistic market framing for early stage. Do not build castles on inflated TAM numbers. SOM is what matters for the next 3 years.

Methodology

1. Privacy gate. Before searching the web for market data, confirm with the user: "I'll search for market data on [industry/category]. This will use general terms only — no proprietary details. Proceed?" Wait for confirmation.
