Which statement is NOT a correct description of market/fit hypothesis?

• A. A rapid growth hypothesis ensures market/fit.
• B. Product/market fit exists when you have the right solution to a problem worth solving.
• C. A fit exists when people need your product rather than just seeing a potential benefit of using it.
• D. When users love your product so much they tell other people to use it.

Answer: (A)

Market/fit hypothesis centers on delivering a real, solvable problem with a solution that customers genuinely adopt in a sizable market. Growth is not the measure of fit; it can happen for reasons unrelated to whether the core problem is indeed solved, such as clever marketing or viral loops, and it can mislead you into thinking the fit is established when it isn’t. The statement that a rapid growth hypothesis ensures market/fit is not correct because rapid growth can occur without true problem-solution alignment or enduring demand, and may stall if the core need isn’t actually being met. A correct description is that product/market fit exists when you have the right solution to a problem worth solving, meaning the solution matches a real need in a sizable market. Fit also means people need your product rather than just seeing a potential benefit of using it, signaling genuine value and necessity. When users love your product so much they tell others to use it, that strong positive word-of-mouth is a powerful indicator of fit and often drives sustainable growth.
