Two of Mark Zuckerberg’s most important executives are leaving Facebook, less than a year after he shuffled their roles

Days after announcing what he said would be a major change in strategy, Facebook CEO Mark Zuckerberg is making more big moves, by reshuffling his executive team.

Zuckerberg says product head Chris Cox, seen by many people inside Facebook as the company’s second-most-powerful executive, is leaving the company after 13 years. Also out is Chris Daniels, who has been running Facebook’s WhatsApp messaging service.

Zuckerberg described both moves as one his executives made of their own accord. But in a memo announcing the changes, Zuckerberg also said both departures were linked in some way to the company’s decision to “build out the privacy-focused social platform” he described last week.

The moves will reverberate in and outside of Facebook — both because Cox had been a key executive for Zuckerberg for years, and because the move comes less than a year after another reorganization, which had given Cox even more power by having all of Facebook’s key app teams reporting to him.

By many accounts, that org structure had frustrated some other key Facebook executives, including Instagram founders Kevin Systrom and Mike Krieger, who announced their departures last fall.

Now Zuckerberg is restructuring the company again. Instead of filling Cox’s role, he’ll have top people at each of his apps report directly to him. Two other longtime executives are getting promotions as part of the change: Will Cathcart will run WhatsApp, and Fidji Simo, who has led Facebook’s video push in recent years, will be the head of that group.

Below is the text of Zuckerberg’s memo describing the changes, and here’s a link to Cox’s own post announcing his move.

Hey everyone -- I want to share some important updates as we organize our company to build out the privacy-focused social platform I discussed in my note last week. Embarking on this new vision represents the start of a new chapter for us.

As part of this, I’m sad to share the news that Chris Cox has decided to leave the company. Chris and I have worked closely together to build our products for more than a decade and I will always appreciate his deep empathy for the people using our services and the uplifting spirit he brings to everything he does. He has played so many central roles at Facebook -- starting as an engineer on our original News Feed, building our first HR teams and helping to define our mission and values, leading our product and design teams, running the Facebook app, and most recently overseeing the strategy for our family of apps. Along the way, Chris has helped train many great leaders who are now in important roles across the company -- including some who will now take on bigger roles in our new product efforts.

For a few years, Chris has been discussing with me his desire to do something else. He is one of the most talented people I know and he has the potential to do anything he wants. But after 2016, we both realized we had too much important work to do to improve our products for society, and he stayed to help us work through these issues and help us chart a course for our family of apps going forward. At this point, we have made real progress on many issues and we have a clear plan for our apps, centered around making private messaging, stories and groups the foundation of the experience, including enabling encryption and interoperability across our services. As we embark on this next major chapter, Chris has decided now is the time to step back from leading these teams. I will really miss Chris, but mostly I am deeply grateful for everything he has done to build this place and serve our community.

At the same time, as we embark on this new chapter, Chris Daniels has also decided to leave the company. Chris has also done great work in many roles, including running our business development team, leading Internet.org, which has helped more than 100 million people get access to the internet, and most recently at WhatsApp, where he has helped define the business model for our messaging services going forward. Chris is one of the clearest and most principled business thinkers I’ve met and the diversity of challenges he has helped us navigate is impressive. I’ve really enjoyed working with Chris and I’m sure he will do great work at whatever he chooses to take on next.

While it is sad to lose such great people, this also creates opportunities for more great leaders who are energized about the path ahead to take on new and bigger roles.

I’m excited that Will Cathcart will be the new head of WhatsApp. Will is one of the most talented leaders at our company -- always focused on solving the most important problems for people and clear-eyed about the challenges and tradeoffs we face. Most recently he has done a great job running the Facebook app, where he has led our shift to focusing on meaningful social interactions and has significantly improved the performance and reliability of the app. In his career here, Will has helped lead our teams focused on security and integrity, and he believes deeply in providing end-to-end encryption to everyone in the world across our services.

I’m also excited that Fidji Simo will be the new head of the Facebook app. She is one of our most talented product and organizational leaders -- passionate about building community and supporting creativity, and focused on building strong teams and developing future leaders. She has played key roles in building many aspects of the Facebook app, including leading our work on video and advertising. She believes deeply in helping people get more value out of the networks they’ve built. She has already led this team for much of last year while Will was out on parental leave, and she is the clear person to lead these efforts going forward.

Our family of apps strategy has been led jointly by Chris Cox and Javier Olivan. Chris managed the leaders of the apps directly and Javi has been responsible for all of the central product services that work across our apps, including safety and integrity, analytics, growth, and ads. Javi will now lead identifying where our apps should be more integrated. Javi is an incredibly thoughtful, strategic and analytical leader, and I’m confident this work will continue to go well. Since we have now decided on the basic direction of our family of apps for the next few years, I do not plan on immediately appointing anyone to fill Chris’s role in the near term. Instead, the leaders of Facebook (Fidji Simo), Instagram (Adam Mosseri), Messenger (Stan Chudnovsky), and WhatsApp (Will Cathcart) will report directly to me, and our Chief Marketing Officer (Antonio Lucio) will report directly to Sheryl.

This is an important change as we begin the next chapter of our work building the privacy-focused social foundation for the future. I’m deeply grateful for everything Chris Cox and Chris Daniels have done here, and I’m looking forward to working with Will and Fidji in their new roles as well as everyone who will be critical to achieving this vision. We have so much important work ahead and I’m excited to continue working to give people the power to build community and bring the world closer together.

Will you support Vox’s explanatory journalism?

Most news outlets make their money through advertising or subscriptions. But when it comes to what we’re trying to do at Vox, there are a couple reasons that we can't rely only on ads and subscriptions to keep the lights on.

First, advertising dollars go up and down with the economy. We often only know a few months out what our advertising revenue will be, which makes it hard to plan ahead.

Second, we’re not in the subscriptions business. Vox is here to help everyone understand the complex issues shaping the world — not just the people who can afford to pay for a subscription. We believe that’s an important part of building a more equal society. We can’t do that if we have a paywall.

That’s why we also turn to you, our readers, to help us keep Vox free. If you also believe that everyone deserves access to trusted high-quality information, will you make a gift to Vox today?
