Calculates TAM (Total Addressable Market), SAM (Serviceable Addressable Market) and SOM (Serviceable Obtainable Market) for a B2B product using two complementary approaches — top-down (from market reports) and bottom-up (multiplying ICP × average ticket size × realistic penetration). Use this skill whenever the user asks "size my market", "calculate TAM SAM SOM", "how big is my market", "how many customers can I have", "what's my market worth", "estimate revenue potential", "do market sizing", "what's my revenue ceiling", "TAM for my category", or similar. Always produces three scenarios: conservative, realistic, aggressive.
