Facebook at Work interview with Julien Codorniou and Kyle McGinn - Business Insider

From an extensive Facebook at Work overview

"The man heading up Facebook at Work is Julien Codorniou, who previously led the company's platform partnerships team.

"I used to work at Microsoft, I have a passion for enterprise software," Codorniou says. "When it was the time to start building a proper growth team for Facebook at Work, when the product was ready to be tested, I volunteered to do it. When it became clear that we had a very nice opportunity there, I decided to go full-time and build the global team."

And that team is, unusually for Facebook, almost entirely based in London (with some support from Tel Aviv). It's the first major Facebook product that wasn't made in the US. Codorniou mentions Facebook's offices in New York and Seattle as other places where the company works on products outside of its Menlo Park HQ, but says that "we wanted to see if we could build a significant initiative for Facebook outside of the US.""
