PayPal: The Pivot to Email Payments

PayPal began in 1998 as a clever way to beam money between Palm Pilots, a device almost nobody owned, solving a problem almost nobody had. Peter Thiel and Max Levchin had the cryptography and the team; what they lacked was a market. Buried inside the company was a small side experiment, a feature nobody considered the main event, that made people light up the moment they saw it. That reaction was the data point that mattered.

For founders and operators, this case is about learning to read the disproportionate response, the one feature that excites people more than your actual pitch does. It sharpens the decision of when to follow that signal even if it means demoting the idea you founded the company on. The move PayPal made looks obvious in hindsight and was anything but at the time, and the case lets you feel why before it tells you what they did.
