Rizvi Traverse were Twatters biggest backers at public offering, holding 15.6%. Pic related.
Interesting snippet of info, too connecting Google:
>The largest stake in Twitter Inc. first came together seven years ago at a posh Caribbean resort.
On Necker Island, a retreat owned by billionaire Richard Branson, Suhail R. Rizvi, a little-known but well-connected financier, met Chris Sacca, a brash, young Google Inc. executive.
Their friendship would later form the foundation of a 15.6% stake in Twitter managed by Mr. Rizvi's investment firm, Rizvi Traverse Management LLC. The journey to that stake—valued as high as $1.7 billion, based on Twitter's price range for its initial public offering—also included a convincing pitch to a Twitter co-founder and caged toy birds that resemble the social-media company's logo.
