Rizvi runs a private investment company Rizvi Traverse Management, which is the largest outside investor in the micro blogging site with a 15.6% stake, which by the end of the day of trading was worth $3.8 billion.
He is famously reclusive, turning down requests from media — including HT for comments and interviews.
Rizvi, who was born in India but grew up in Iowa, began his investment career with telecom and then the entertainment industry, before turning to IT.
He began investing in Twitter around 2010 when long-time friend Chris Sacca, a former Google executive, told him that Evan Williams, had stepped down as CEO of Twitter and was seeking to sell his 10% stake. Rizvi bought the shares for $340 million. There was no looking back from that.
Rizvi reportedly owns a sprawling three-home compound in Florida, and is friends with Virgin founder Richard Branson and has been seen partying on Google CEO Eric Schmidt’s yacht.
