TAM / SAM / SOM Market Sizing

Produce both a bottom-up and a top-down analysis for every engagement. Both methods are required — they serve different purposes and must be reconciled. The goal is a defensible, sourced output — not a fast estimate.


When to use this skill

Trigger on any prompt that contains:

  • "TAM", "SAM", "SOM", or "market size"
  • "How big is the market for X"
  • "Total addressable market", "serviceable market", "obtainable market"
  • "Market sizing for [product/company]"
  • Investor deck context requiring market opportunity quantification
