Ehsan's Insight
SAM is the most useful and most ignored market sizing metric. TAM is your theoretical ceiling. SAM is your realistic ceiling given your current product, geography, and sales capacity. A developer tools company with an English-only product and no enterprise sales team has a SAM that is roughly 15-20% of their TAM. That is the number they should plan against. Most startups plan against TAM and then wonder why growth stalls at $5M ARR — they hit their SAM, not their TAM. Expanding SAM requires deliberate investment: localization, new product features, additional sales channels. Map your SAM quarterly and identify which investments would expand it most efficiently.
