What does ‘hair on fire’ mean?
Hair on fire is sales-and-startup jargon for a customer problem so urgent, painful and unavoidable that the customer will pay anything — and act now — to solve it. The metaphor evokes someone running into a store demanding water immediately. ‘Hair-on-fire problems’ are the ideal target for early-stage product-market-fit.
Founders are advised to find hair-on-fire problems early because they yield shorter sales cycles, higher willingness to pay and faster validation. Vitamin-not-painkiller problems — nice but not urgent — require longer education cycles and tend to commoditise faster.
