The customer only knows what she thinks she wants based on her experience with the current product. The innovator can take into account everything that’s possible, but often must go against what she knows to be true. As a result, innovation requires a combination of knowledge, skill, and courage. Sometimes only the founder has the courage to ignore the data; we were running out of time, so I had to step in: “I don’t care about any of the existing requirements; I need you to reinvent the product and we need to win.”
