TAM, SAM, SOM — What Each Number Actually Means
The total global revenue opportunity if your product captured 100% of the market. Used to establish category scale.
The portion of TAM your product and business model can realistically address given geography, segment fit, and channel.
The share of SAM you can realistically capture in 3–5 years given competitive dynamics, team, and go-to-market.
Most market sizing fails not because the methodology is wrong, but because the data quality is poor. Analysts cite a single industry report. Numbers get rounded. Sources go unchecked. Investors have seen this pattern — and they push back.
