Facebook Director of Corporate Communications Larry Yu announced in a post on his Facebook page that he is leaving the social network to join communications consultancy The Pramana Collective, teaming up with friends Brandee Barker, former Facebook head of public relations; Brian O’Shaughnessy, former head of global communications at Skype; and Sean Garrett, former head of communications at Twitter.

Yu posted Monday:

Nearly five years ago, I joined some friends at a privately held company called Facebook to help a small team scale and expand upon the company’s story. That journey was, in a word, crazy. And fun. Terrifying. And gratifying. So I’m off to do it again. I’m joining my friends Brandee, Brian, and Sean to help build The Pramana Collective, a project-focused communications consultancy that works with cool companies. To the amazing people that I was fortunate enough to work with during my time at Facebook — thank you. You’ve taught me so much and I’ll be forever grateful. I could go on, but then I’d be a blubbering mess. So I’ll just say that I am proud to be affiliated with such a remarkable company. And I won’t be far, so this isn’t goodbye. It’s see you around.

And as reported by TechCrunch, Garrett posted on his personal blog:

Today, we are making a big first step with the addition of Larry Yu as a partner. For nearly five years, Larry has been a key player at Facebook in his role as director of global communications and public policy. There, he built a great team and led the company through some of its biggest corporate and financial milestones. Among other gigs, Larry is also part of the Google and Cisco alum network.

Brian, Brandee, and I have all worked with Larry in the past, and we know that his close to 20 years of experience is a perfect fit for The Pramana Collective and our clients. Beyond being a thoughtful guy who is universally liked and respected, Larry knows how to navigate companies through chaotic growth stages with confidence and calm. And we all admire how he makes financials, process, and operations look easy, maybe even fun (well, almost).
