hamzafarooq 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").
