Rizvi Traverse is not the guy's name. That's his investment company, Rizvi Traverse Investment Company, he co-founded. His name is Suhail Rizvi. . . SR.
It is entirely possible representatives of Rizvi Traverse might be at the meeting as they are the major outside investors in both Twitter and Facebook.
Per their website they are no longer invested in FB. But he has apparently taken money from Prince Alaweed.
