Jan Koum, the CEO and cofounder of Facebook-owned WhatsApp, confirmed Monday that he is leaving the company.

The departure comes nearly four years after Facebook (FB) completed its acquisition of the messaging service for $22 billion, the largest purchase in its history. In addition to running WhatsApp, Koum also served on Facebook's board.

The Washington Post was first to report Koum's departure. The publication said Koum had clashed with Facebook over its approach to personal data and encryption.

In response to a request for comment, Facebook directed CNN to Koum's farewell post.

"I'm leaving at a time when people are using WhatsApp in more ways than I could have imagined,"Koum wrote in a Facebook post Monday. "The team is stronger than ever and it'll continue to do amazing things".
