Akio Morita

In 1979, Sony's engineers told Akio Morita that a portable cassette player with no recording function and no speaker would not sell. The market research agreed: people would not buy a tape player that could not record, and the missing speaker looked like a defect. Morita overruled all of it and reportedly told his team that if they did not sell 100,000 units in the first month, he would resign. The Walkman sold 50 million units in its first decade and changed how humans listen to music.

For founders and operators, this case is about the conviction to bet on a behavior that does not yet exist, not just a product that is marginally better than the current one. It asks whether there is a feature or experience you have not built because customers said they would not use it, even though you believe they would love it once they tried. How Morita read past the research, and the smallest way to test that kind of bet, is the part the app keeps for you.
