What is Serviceable Addressable Market (SAM)?

Short answer: The portion of the total addressable market that a specific product can realistically serve given its current business model, geography, and positioning.

Definition

The portion of the total addressable market that a specific product can realistically serve given its current business model, geography, and positioning.

Why it matters for growth

SAM is a more honest planning number than TAM, since it excludes segments the product cannot actually reach or serve today.

Example

Out of a $2 billion TAM, a founder estimates a $400 million SAM by excluding regions where the product isn't yet localized.
