Customer segmentation

Process of dividing customers into groups based on shared characteristics.

Definition

Customer segmentation is the process of dividing customers into groups based on shared characteristics. Founders reach for it when a vague conversation needs a shared, specific meaning. Name it clearly, then let the next decision — a hire, a price, a test, or a pass — follow from that meaning.

How the word shows up in a real conversation.

Two cofounders disagree until they define Customer segmentation. Once they agree it means “Process of dividing customers into groups based on shared characteristics”, the argument becomes a decision.

Common mistake

Using Customer segmentation as a label instead of a fact. If you cannot point to the evidence — a number, a customer, or a written assumption — you are using the word as jargon.
