Zuckerberg’s Sis Randi Quits Facebook Job to Start New Company

Facebook Director of Marketing and sister of Mark Zuckerberg, Randi Zuckerberg, is leaving the massive social network to start her own social firm, it has been revealed.

The other Zuckerberg had been out on maternity leave when she made the decision, and AllThingsD got ahold of her resignation letter. In it, she talks about her aspirations in the post-Facebook future:

“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. We have made incredible progress, but there is still much to be done and other ways I can affect change. Now is the perfect time for me to move outside of Facebook to build a company focused on the exciting trends underway in the media industry.”

Facebook confirmed Randi’s impending departure from the company in a brief statement:

“We can confirm Randi has decided to leave Facebook to start her own company. We are all grateful for her important service.”

Randi’s brother did not comment directly on his sister’s defection.
