What problem does it solve? Sizing a market opportunity credibly is hard: teams either quote a single unsupported TAM figure or skip the analysis entirely, leaving investment cases, business cases, and market-entry decisions without defensible numbers. This Skill produces a structured TAM, SAM, and SOM estimate with cited sources and explicit assumptions. ## Core Features & Use Cases - Dual-method estimation: Builds both top-down estimates from published sector spend and bottom-up estimates from units (customers, contract value, frequency) to cross-validate results. - Contract and programme-aware sizing: Adapts TAM, SAM, and SOM for businesses selling through tenders, frameworks, and procurement rather than open-market retail, gating SAM by accreditation and SOM by route to contract. - Assumption transparency: Numbers every key assumption, rates confidence, and states how to validate the most uncertain ones. - Use Case: A founder preparing an investment case asks for the addressable market for their product; the Skill returns a market definition, sourced TAM/SAM/SOM figures, a 2-3 year projection table, growth drivers, and a confidence-rated assumption list. ## Quick Start Ask the assistant to size the market for your product or service using TAM, SAM, and SOM with both top-down and bottom-up estimates and cited sources.
