Total Addressable Market (TAM)
정의
TAM is the total revenue opportunity if a product captured its entire market; SAM (serviceable addressable) narrows to the reachable segment, and SOM (serviceable obtainable) to a realistic share.
투자유치 시 활용 방법
Investors prefer bottom-up TAM (number of target customers times realistic price) over top-down slide math, which they discount on sight.
자주 묻는 질문
How big must TAM be for venture capital?

What is bottom-up market sizing?
Counting actual buyers and multiplying by achievable pricing, the way Uber’s famous deck sized taxi spend from first principles.
