Naveen Selvadurai is best known as a co-founder of Foursquare, the location-based social app. He keeps a low public profile, so reliable detail about his finances and personal life is limited. This article sticks to what could be verified and flags the rest.
Net Worth
There is no Forbes or Bloomberg ranking for Selvadurai, so every figure is a third-party estimate.

| Source | Estimate | Notes |
| Celebrity Net Worth | $80 million | Undated estimate, widely copied by other sites |
| Wealth-X (2011 list) | $55 million, ranked 29th among social media entrepreneurs | Snapshot from when Foursquare was near its peak |
Realistic range: roughly $55 to $80 million. The Wealth-X figure is old, and the $80 million figure is repeated across many sites without clear sourcing, so treat both as rough. His wealth likely comes from his Foursquare equity and later startup investing, but his current holdings aren’t public. Several SEO sites hint at much larger figures or mix him up with unrelated people, so ignore those.
Biography
Selvadurai moved from India to the United States and trained as a software engineer, which shaped his later role on the technical side of Foursquare.
Career
He co-founded Foursquare with Dennis Crowley, and the two built it into one of the best-known early mobile apps, where users “check in” to places. In early 2011, Foursquare was reportedly valued at $250 million, with the company’s co-founder predicting about 10 million users by June. In 2011 he was listed as co-founder and CTO.
He left the company in 2012. Business Insider reported that he had tried to fight his departure, so the exit does not appear to have been entirely voluntary. In 2014, TechCrunch reported he joined Expanse as its New York partner. At Expanse he works with early-stage startups.
Lifestyle
Selvadurai is private, with little public information about his homes, spending or hobbies. His public footprint is mostly professional: product building, startup mentoring and appearances tied to technology and entrepreneurship. Any article claiming details about his cars, properties or luxury purchases is most likely guesswork.
Family
Family details are sparse. One profile site lists his spouse as Diana Marie Hardeman, married in 2017, but it is a low-quality source and I couldn’t confirm it elsewhere, so treat it as unverified. I found no reliable information on children.
Conclusion
Naveen Selvadurai is a respected figure from the early mobile-social era whose reputation rests on helping build Foursquare and later supporting new startups through Expanse. His net worth is probably in the tens of millions of dollars, but exact figures aren’t public. Most of his personal life remains out of view.
