Facebook Co-founder Eduardo Saverin Says “No Hard Feelings” Towards Mark Zuckerberg

Eduardo Saverin, the Facebook co-founder whose tense relationship with former business partner Mark Zuckerberg was famously portrayed in the film The Social Network, has denied persistent rumours of a rivalry. There are "no hard feelings" between him and Zuckerberg, he said in an exclusive interview with a Brazilian magazine.

The contention depicted in the Aaron Sorkin-written, David Fincher-directed film is a "Hollywood fantasy, not a documentary", Saverin said.

He also described Zuckerberg as a "visionary" whose commitment to Facebook and the notion that users sign up with their real names was instrumental to the social network's success.

"That's Facebook's biggest strength, what allowed us to transform it into an instrument of protest, like what happened in Egypt, but also in an instrument of business", he said.

Saverin, who is worth an estimated $2 billion (£1.2 billion), recently made news after he announced plans to renounce his U.S. citizenship. Despite speculation that the move was designed to help him avoid millions of dollars in taxes, the Brazilian-born entrepreneur insists it was a strategic move to facilitate business transactions in Singapore, where he has lived since 2009.

He's currently "investing like a crazy person" in internet and tech startups, a move that is fueled by his quest to find a "new Facebook". He's betting on finding in it health care, he said.
