Interviews Aren't Data, but Surveys Are

If you haven't found anyone excited about your idea in five or so interviews, either you're talking to the wrong people or your problem isn't a real problem for customers. If only a few people see your opportunity as a pain point they care about, the potential market for your product might not be large enough to matter. Sometimes you'll notice customers discussing the same pain point again and again, even if it's different from your opportunity. Absolutely note this pain point and analyze if it's a better opportunity,. has a bigger value, lower cost, et cetera, than the one you're looking at.
