TAM, SAM, SOM

TAM (Total Addressable Market) is the entire demand for a solution; SAM (Serviceable Addressable Market) is the slice you can reach with your model and geography; SOM (Serviceable Obtainable Market) is what you can realistically win in a set period. Sizing them top-down, bottom-up, and by value keeps fundraising and strategy grounded.
