WhatsApp was acquired by Facebook in 2014, for $19 billion - $4 billion in cash, $12 billion in stock, plus $3 billion in RSUs (Restricted stock units are not fully transferable until certain conditions have been met).
Mr. Acton's exit comes as WhatsApp lays the groundwork to make. Acton, a Stanford alumnus, had co-founded WhatsApp with Ukrainian immigrant Jan Koum in 2009. I've made a decision to start a non-profit focused at the intersection of nonprofit, technology and communications.
Acton confirmed the news of his leaving the office via a Facebook post.
With a net worth of roughly $6.5 billion, Acton now overlooks the company's engineering team and is expected to hand off his duties to other engineers.
It would be worth mentioning here that before launching the messaging app Brian had actually applied and interviewed for a job in Facebook, but wasn't hired.And not just Facebook but Twitter also denied him job. Currently, WhatsApp generates no revenue and is a free service for 1.2 billion users across the globe. This decision is, of course, a tough one.
After the acquisition by Facebook, Acton was leading the engineering efforts at WhatsApp.
Further, the leaks suggest that the when the sender deletes the message for everyone, WhatsApp will delete it in the Notification Center.
