Total Addressable Market (TAM)
Total Addressable Market is the full set of companies or buyers that could ever use your product, and it sets the ceiling on how much you could sell.
Why it matters
TAM tells you how big the opportunity is and where its edges are. A clear TAM keeps go-to-market focused on reachable demand and stops teams chasing accounts outside the market. It also grounds planning: pipeline targets and territory sizes only make sense against a known market size.
How it works in practice
TAM is defined by the firmographic traits that describe a fit: industry, size, geography, and any hard requirements your product needs. You count the companies that match those traits, then narrow to a serviceable segment you can actually reach and sell to. The count comes from filtering a data source on your ICP criteria.
Common mistakes
A common mistake is inflating TAM by counting companies that will never buy, which sets false expectations. The opposite error is defining it so narrowly that real demand is left out. A third is treating TAM as fixed, when it shifts as your product, pricing, and market change.
How hubsell approaches it
hubsell sources against your ICP criteria on demand, so you work the reachable slice of your market with current contacts rather than estimating from a static database.
