SAM
Also known as: Serviceable Addressable Market
Serviceable Addressable Market — the portion of TAM you can realistically serve given your product, geography, and go-to-market.
SAM (Serviceable Addressable Market) is the portion of TAM realistically reachable given constraints like geography, product fit, language, and regulation. A global TAM of €10B may translate to a SAM of €200M in the Benelux.
SAM is the most useful market metric for strategy: it's your actual playing field for the next 3-5 years.
