TAM (Total Addressable Market)

20 April 2025

The estimated number of potential customers who share characteristics with your best existing customers.

Knowing your TAM helps you understand how big your growth opportunity really is. It’s an essential metric for prioritizing acquisition efforts, developing scalable marketing strategies, and guiding geographic expansion.

Our downloadable PDFs of Prizm and Lifestage Personas tell you the size of the TAM for each segment. The TAM clearly punctuates how big and real the opportunity is for you to scale, when you know your best customer segments.
