Definition
Key customer is the important client whose business significantly impacts company revenue and success. 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.
In the room
How the word shows up in a real conversation.
In a Monday review, someone writes Key customer on the board and restates it: “Important client whose business significantly impacts company revenue and success.” The next move is a test, a cut, or a double-down — not another debate about the word.
Common mistake
Using Key customer 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.
