TAM Metric
Noun · Startup & VC
Definitions
The total addressable market figure used to estimate the full revenue opportunity if a company could serve all plausible demand in its category. Because TAM can be stretched beyond reality, its usefulness depends on how credibly it is defined and segmented.
In plain English: A measure of the total possible market size a company could theoretically serve.
Example: "The TAM metric looked impressive, but investors wanted to know how much of it was realistically reachable soon."
