"It's clearly a tough act to follow," the 30-year-old Brazilian billionaire told a business conference in Singapore, where he is a permanent resident and putting money as an "angel investor" into Asian and other start-ups.
"Asia is, whether you look at Internet growth, mobile growth, it's the centre in terms of where the user and consumer base will be in the future, so it's phenomenal for me to come here and learn," he said.
Saverin who was listed by Forbes magazine as Singapore's eighth-richest individual in 2012 with a fortune estimated at $2.2 billion said he was not trying to recreate Facebook's success.
"Every step of my life is not about creating a new Facebook or something new necessarily that goes and gets distributed to a billion-plus people," he said.
"It's about making sure that what I do is fulfilling both to myself and others in the world."
Saverin, who moved to Singapore nearly four years ago but rarely speaks in public, said at the conference hosted by the Wall Street Journal that Facebook had become a "democratising force" across the world.
"The impact is huge," he added, citing the role of social media in the Middle East democracy movement known as the Arab Spring as well as in mobilising public support after natural disasters.
Founded in 2004, Facebook says it amassed more than a billion monthly active users as of December 2012.
Its shares have been been hit by volatility since its initial public offering price of $38 in May 2012. The stock closed at $28.46 on Wednesday.
Saverin, an economics major at Harvard University, co-founded Facebook in 2004 with three fellow students including current chief executive Mark Zuckerberg.
His role was famously portrayed in the 2010 film "The Social Network", in which he started out as a close friend of Zuckerberg and provided initial funds for the site before they had an acrimonious split.
Saverin said Thursday that he and Zuckerberg "don't talk very often now but I very much admire him and everything that he's doing for the company, and everyone else at Facebook".
As an investor in technology start-ups, Saverin said Asia held the biggest opportunities for entrepreneurs like him.
He again rejected suggestions that he moved to Singapore and renounced his US passport to take advantage of lower taxes in the city-state, saying it was a "personal decision" that had nothing to do with money.
"I don't really look at money as something I need. I just want to be happy."
