Mark Zuckerberg’s Sister Resigns from Facebook

Posted Aug 4, 2011

Randi Zuckerberg is leaving her position as Facebook’s director of marketing. She is the sister of co-founder and CEO Mark Zuckerberg, and has been with the company for six years. Zuckerberg says she is leaving Facebook to start her own company, a social media firm called RtoZ Media. AllThingsD reports that Facebook has confirmed her departure, but that her brother has made no comment on the matter.

Zuckerberg’s letter of resignation says “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.” She chose to leave Facebook after three months on maternity leave, a break that sources say gave her time to decide on the career move.
