EXECUTIVE SUMMARY:
Customer segmentation divides a broad market into smaller groups that share similar characteristics, so a company can decide who it serves and how. The common approaches sort customers by demographics, geography, psychographics, behavior, or, for B2B companies, firmographics. Each of those describes who customers are and how they act without explaining why they choose what they choose.

Personas then turn a segment into a specific person with a name, a situation, and a stated job, which gives a team something concrete to design and market against.

It tells your marketing team where to focus messages, your product team what to build, and your sales team which opportunities to pursue. Without it, you risk spreading resources too thin or chasing the wrong customers altogether.
There are several common approaches to segmentation…
