Everything You Need to Know

TAM (Total Addressable Market) is the total global or national revenue opportunity for a product category if you captured 100% of the market. SAM (Serviceable Addressable Market) is the portion of TAM you can realistically target given your product's geography, distribution, and price point. SOM (Serviceable Obtainable Market) is the slice of SAM you can realistically capture within 3–5 years given competition and your go-to-market resources. Investors focus most on SOM — it shows you are thinking clearly about realistic near-term scale.
