Serviceable Available Market (SAM)
Serviceable Available Market (SAM) is the portion of the Total Addressable Market that a company can realistically target given its current product capabilities, geographic reach, regulatory constraints, and business model. SAM is a more practically useful measure than TAM for GTM planning because it defines the realistic scope of market opportunity. Investors and go-to-market teams use SAM to evaluate whether a company's growth ambitions are realistic given its current product and market position.
Why It Matters
SAM grounds market opportunity claims in operational reality. A $50B TAM means nothing if the company can only realistically serve $500M of it given current product scope, geographic presence, and go-to-market capacity. SAM focuses GTM resources on the opportunity that is actually accessible.
Example
A vertical SaaS company calculates its TAM for restaurant management software globally but defines its SAM as US-only, full-service restaurants with more than three locations — reflecting the reality of its current product, sales capacity, and go-to-market coverage.
