Facebook said Thursday that Zuckerberg, who had led Facebook's consumer marketing team, is leaving to start her own company. Facebook says the company is "grateful for her important service."
Zuckerberg did not immediately respond to an email for comment.
The blog AllThingsD, which earlier reported her departure, says she is leaving to start a company called RtoZ Media. Few details are available on the startup's website, which says RtoZ is still working on "absolutely everything about this new initiative."
The venture will likely build on Zuckerberg's work at Facebook. There, she worked with media companies to bring elections and other current events to the social network.
