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]
