Facebook's director of marketing Randi Zuckerberg, sister of the social network's billionaire founder Mark Zuckerberg, is leaving her brother's company to start her own social media consulting company RtoZMedia.

Randi, who has been with Facebook for the last six years, said she feels it is the "perfect time" to move outside of Facebook to build a company focused on the "exciting trends underway in the media industry."

Here’s her Facebook Status Update where she announced about this:

According to her resignation letter posted on the website AllThingsD, Randi said she has focussed on innovating and pushing the media industry forward by introducing new concepts around live, social, participatory viewing.

"We have made incredible progress, but there is still much to be done and other ways I can affect change."

A prominent name in Silicon Valley, Randi has been on maternity leave for the last three months. She was recently nominated for an Emmy award in the category of live coverage of a current news event for her work on 'Facebook Live', a real-time news show she created and hosted for the company.
