Definition
Zero-based budgeting is the budgeting method that starts from zero and requires justification for all expenses. 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.
A mentor asks, “What is your Zero-based budgeting?” The useful answer is concrete: budgeting method that starts from zero and requires justification for all expenses. A slide title is not an answer.
Common mistake
Using Zero-based budgeting 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.
