Serviceable addressable market (SAM) represents the portion of the total addressable market (TAM) that a business can realistically serve based on product scope, geography, and customer profile. It narrows TAM into a more actionable view of true opportunity.
In B2B strategic planning, SAM helps teams focus on the market segments where their offering is relevant and competitive. It provides clearer boundaries for go-to-market strategy and helps justify where resources should be allocated.
Understanding SAM allows organisations to prioritise the highest-value customer segments and design messaging, pricing, and distribution strategies that align with real-world potential.
