Randi Zuckerberg Leaves Facebook to Launch Startup

Mark's sister had been marketing director

Randi Zuckerberg, Facebook’s marketing director (and sister of founder Mark), is leaving the company after six years to launch a social media firm called RtoZ media, AllThingsD reports.

“I have spent my years at Facebook pouring my heart and soul into innovating and pushing the media industry forward by introducing new concepts around live, social, participatory viewing that the media industry has since adopted,” Zuckerberg wrote in her resignation letter. “We have made incredible progress, but there is still much to be done and other ways I can affect change.

Zuckerberg has been on maternity leave for the past three months, and sources say that she has used that time away from the daily grind at Facebook to consider where she wants to go with the next phase of her career.

“I'm proud of what I've done here and the people I have had the chance to work with,” she wrote. “But I know I'll be able to do just as much or more for Facebook once I'm on the outside. My goal is to launch my own innovative programming and work with media companies to develop their programming in new and more social ways.”

When reached by Adweek, Facebook confirmed Zuckerberg's resignation, saying, “We can confirm Randi has decided to leave Facebook to start her own company.  We are all grateful for her important service.”
