e.g. 20%
What % of your SAM could you realistically capture in year one?
e.g. 3%

SAM (Serviceable Available Market) is the portion of TAM you can realistically reach with your product, channels, and geography. SOM (Serviceable Obtainable Market) is the portion of SAM you could realistically capture in a given period, usually year one.
