 Oliver Estreich is almost too easy a target. As the founder of the Native Society, a new social network for the city's young, privileged and preppy, he just begs to be mocked. He's 24 and wears cuff links. He owns his own tuxedo. He threw his group's inaugural event in November at the Plaza because, he says, it was "nostalgic" for members who'd spent so much time there as children.

His organization, the Native Society, is a loose collection of the city's elite kids who went to private schools, left briefly to attend Colby, Trinity, Harvard, Princeton and the like, and have since returned to take up the reins as New York City's ruling class.

Estreich says the idea for his organi­zation was organic: His friends kept saying to him, "How is so-and-so? I haven't seen him around for a while; I wish I ran into him more often." Estreich, a self-proclaimed "social butterfly" even back in his Browning School days (that's a private school on the Upper East Side that costs about $35,000 a year to attend), caught a whiff of opportunity.

Instead of simply throwing a party or forming a new social organization like, say, the Union League Club for Kids, Estreich went the Zuckerberg route. He enlisted a group of "administrators"—a.k.a. his best friends—and built a free, password-protected online social network called theNativeSociety.com, where members could interact safe from the prying eyes of the hoi polloi.

Now, a handpicked group of New York's wealthiest sons and daughters, including Peter Davis and Anne de la Mothe Karoubi, can flirt, chat and talk business privately. But such is his reach that in just four months Estreich has attracted almost 400 members—400 posh, young, beau­tiful members.

"How did we pick up steam so quickly?" he asks rhetorically over a $22 grilled cheese sandwich at the Royalton Hotel in Midtown recently. "That's a great question. People must have really loved the concept. I guess it was in demand."

"We wanted to create an intimate gathering of friends and like-minded individuals who could meet in a relaxed atmosphere. It's just fostering a certain environment among people who know each other," he declares, cutting his grilled cheese with a knife and fork.  

If Estreich sounds vague, it's because much of what he says seems intentionally obfuscating. He speaks like a trained politician, using the word diverse 16 times over the course of an hour and chuckling—never outright laughing—when he finds something amusing. Other  words he repeats on a loop: versatile, entrepreneurial, go-getters and, sometimes, those words in combination, as in versatile go-getters.  

Some other interesting facts about Estreich: He grew up on 85th and Park with his architect father, his interior-decorator mother and an older brother; after the Browning School, he attended George Washington University, where he majored in business and psychology; his favorite author is Bret Easton Ellis; favorite artist, Damien Hirst; favorite museum, MoMA; and he listens to "everything from Beethoven to Cut Copy." He won't say exactly where he works, except that it's "in hospitality." He won't name his favorite restaurant, but he "went to Orsay recently."

In December Estreich was publicly lampooned when gossip Web site Guest of a Guest spotted him at the Native Society's Classic Car Club event and immediately zeroed in on him wearing a baby blue turtleneck and a sports coat, holding a highball glass aloft as if he were Patrick Bateman at the Odeon.
