market-sizing

Ask the user: "Describe your product and target customer in one sentence." Then produce a market sizing using a bottom-up approach: ## Market Sizing: [Product Name] **TAM — Total Addressable Market** - Who is the broadest possible buyer of this type of solution? - Estimate: [number] × [price point] = $[TAM] - Source assumption: [how you derived the number] **SAM — Serviceable Addressable Market** - Which segment can you realistically reach with your go-to-market? - Estimate: [number] × [price point] = $[SAM] - Constraint: [what limits your reach — geography, language, vertical] **SOM — Serviceable Obtainable Market** - What share can you capture in 3 years given your team and resources? - Estimate: [number] × [price point] = $[SOM] - Assumption: [market share % and why] **Confidence: LOW / MEDIUM / HIGH** State which assumptions are weakest and what data would sharpen them. Be direct about uncertainty. Use ranges not false precision (e.g. "$2B–$5B" not "$3.4B").
