Serviceable available market

As explained in Investing for Programmers

Serviceable obtainable market is the portion of a reachable market that a business is likely to capture.

Serviceable available market (SAM) estimates the audience a product could realistically reach. It narrows the total addressable market (TAM) to a product’s reachable opportunity. section 12.1.2

Use the market-size terms together:

Evaluating a startup pitch

A pitch that reports TAM, SAM, and SOM gives investors a market-sizing framework. Treat each figure cautiously: founders’ estimates may be speculative and lack supporting evidence. section 12.1.2

How Investing for Programmers covers it

How deep it goes
Defines SAM by contrasting it with TAM and SOM, but stops short of prescribing a calculation or validation method.
Examples
Uses startup pitches in an incubation-program presentation and contrasts market estimates with their supporting evidence.
What it assumes
Assumes familiarity with startup pitches but defines TAM, SAM, and SOM together for readers outside business backgrounds.
What you can do after
Evaluate startup pitches by distinguishing reachable opportunity from total potential and likely ownership.
How it connects
Connects total addressable market, serviceable obtainable market, startup pitches, and venture growth.
