TAM
TAM, which stands for Total Addressable Market, is a key concept in venture capital and business planning. It represents the total possible market size for a product or service if a company could reach 100% of potential customers. Think of it like measuring the size of the whole pie before deciding how big a slice a company might realistically get. Investors and business planners use TAM to understand the growth potential of a business or startup. For example, if someone says the TAM for electric vehicles is $500 billion, they mean that's how much money could be made if every potential customer who might buy an electric vehicle did so.
