Why Does Hiten Shah Say Companies Lose Product-market Fit?

Hiten Shah tells PressNomics host Sean Tierney that companies lose product-market fit when they stop paying attention to the customer and stop asking what problem to solve next. Shah is the co-founder of FYI, Crazy Egg, and Kissmetrics, and he writes the Product Habits newsletter with his co-founder Marie. Tierney notes that Shah has advised more than 120 companies, and reads out LinkedIn, Recurly, SlideShare, Clearbit, Buffer, Gusto, and Front. Shah's line on the episode is the Zig Ziglar motto Tierney quotes back: you get what you want if you help enough other people get what they want.
