Practice The biggest B2B customer

The biggest B2B customer

About the exercise

It’s a typical financial research for B2B products: which customer is the biggest (aka “brings the most revenue”)? In the beginning of any B2B startup those customers are precious – losing one might mean the end of a startup.
