TAM, SAM, and SOM

What are TAM, SAM, and SOM? 

TAM, SAM, and SOM are concepts that refer to the market size a product or service can target. 

• TAM (Total Addressable Market) is the entire market that a product or service can target globally. 
• SAM (Serviceable Addressable Market) is the portion of the market a company can address based on its business model.
• SOM (Serviceable Obtainable Market) is the portion of the SAM a company can reach with its current capabilities, whether due to geographic or financial constraints or the niche it aims to serve. 

These concepts help narrow down the market size and understand how to continue growing in the market being served, which is essential for defining the go-to-market strategy.
