Jan Koum Net Worth 2024

In 1997, Jan Koum was hired by Yahoo as an infrastructure Engineer, shortly after he met Brian Acton while working at Ernst & Young as a security tester. Over the next nine years, they worked at Yahoo. In September 2007 Koum and Acton left Yahoo and took a year off, traveling around South America and playing ultimate frisbee. Both applied, and failed, to work at Facebook. In January 2009, he bought an iPhone and realized that the then-seven-month-old App Store was about to spawn a whole new industry of apps. He visited his friend Alex Fishman and the two talked for hours about Koum's idea for an app over tea at Fishman's kitchen counter. Koum almost immediately chose the name WhatsApp because it sounded like "what's up", and a week later on his birthday, February 24, 2009, he incorporated WhatsApp Inc. in California.
