Final answer:
Customers in the lead segment of the customer pyramid are labeled as such because they are the least profitable. They typically make infrequent purchases and require more attention compared to the revenue they generate, leading businesses to evaluate strategies to either increase their profitability or reduce the resources dedicated to them.
Step-by-step explanation:
In the customer pyramid, customers in the lead segment get their name for Being the least profitable. These customers tend to buy little and infrequently, they are price-sensitive, and they often require more service and attention relative to the revenue they provide, which makes them less profitable for a business. While they are part of the customer base, companies often seek strategies to either migrate these customers up the pyramid to more profitable segments or minimize the resources spent on them.
