Brian Acton, who co-founded WhatsApp along with Jan Koum in 2009, announced in a Facebook post that he is leaving the company. He said that he plans to start a new chapter in his life and start a non-profit.
A Stanford alumnus, Acton co-founded WhatsApp with Ukrainian immigrant Jan Koum in 2009. The duo worked at Yahoo before starting WhatsApp.
Acton, who started at Facebook when WhatsApp was acquired for $19 billion in 2014, is the lesser-known of WhatsApp’s two co-founders. Ironically, Acton interviewed at Facebook back in 2009 after leaving a job at Yahoo, but he was not hired.
Acton led engineering internally for WhatsApp, and a source close to the company says he was a big advocate for WhatsApp’s push into encryption. His role won’t be filled by any one employee, according to a company spokesperson.
After 8 years at WhatsApp, I have decided to move on and start a new chapter in my life.
I am very fortunate at my age to have the flexibility to take new risks and focus on what I’m passionate about. I’ve decided to start a non-profit focused at the intersection of nonprofit, technology and communications. It’s something I’ve thought about for a while, and now it’s time to just focus and execute. I’ll have more to share in the coming months.
This decision is, of course, a tough one. I’m proud of what our team has accomplished in only a few years, and it’s humbling to see that so many people rely on WhatsApp every day.
