WhatsApp co-founder Jan Koum has put out word that he is leaving Facebook, which bought the smartphone messaging service four years ago for USD 19 billion.
Koum said in a post on his Facebook page that he is taking time off to pursue interests such as collecting air-cooled Porsches, working on cars and playing ultimate Frisbee.
US media reports indicated that a disagreement with Facebook over the privacy of user data may have also been a factor in Koum's decision to quit his position as a high-ranking executive and likely leave his seat on the board at the leading online social network.
"It's been almost a decade since Brian (Acton) and I started WhatsApp, and it's been an amazing journey with some of the best people," Koum said in the post.
"But it is time for me to move on."
