The Serviceable Available Market (SAM) refers to the segment of the [[Total Addressable Market (TAM)]] that a company can realistically serve with its products or services, considering factors such as geographical reach, regulatory constraints, and current operational capabilities. SAM is essentially a subset of TAM and reflects the portion of the market that aligns with a company's business model and strategic goals. While TAM represents the total revenue opportunity available if a company could capture 100% market share across all potential customers globally, SAM narrows this down to what is feasible given current resources and limitations. In contrast, the [[Serviceable Obtainable Market (SOM)]] is even more specific; it represents the portion of SAM that a company can realistically capture in the short term, considering competitive dynamics and market penetration strategies.
