Jan Koum, the founder of messaging app WhatsApp, plans to leave Facebook after apparent clashes with the higher-ups regarding data privacy and other topics. After a recent social media post, Koum seemed unhappy with parent company Facebook, and seemed pretty willing to leave the millions of dollars he had waiting for him, if he intended to stay employed under the successful social media site. Koum sold WhatsApp back in 2014 for a whopping 19 billion dollars with his co-partner Brian Acton. His departure could cost him as much as 1 billion dollars in stock rewards, as the rewards are contingent on him still being with the company through specific dates. Apparently, he is forfeiting close to six million shares, worth just under 1 billion U.S. dollars. Koum claimed, “it is time for me to move on”, and although he did say he wanted to enjoy life outside of technology, he, nor Facebook, decided to comment further on his sudden, somewhat surprising departure.
