Kacper Postawski climbs slowly from the cockpit of the two-seat Marchetti fighter jet, pauses for a shaky moment on the wing, and crawls to a patch of tarmac shaded by a fuel tank from the Las Vegas sun. When someone asks how he's doing, the internet entrepreneur holds up a plastic baggy of his own vomit.

Welcome to Maverick Business Adventures. At most networking events, "high speed" is a golf cart on a straightaway, but the Mavericks are reimagining the business trip and bonding with their peers over activities like flying fighter jets, racing dune buggies, and floating in zero gravity aboard a specially modified aircraft. And they're paying well for the privilege. Each of the group's trips costs about $9,000 per person in addition to membership fees of up to $5,000 a year.

The group's founder, internet-marketing pioneer Yanik Silver, says he started the group to try to combine all his favorite activities. "What are the things I really love?" Silver says he asked himself one day. "Adventure, partying, [and] business. So I had this idea for M.B.A. that had been sitting in my idea journal."

The members of M.B.A. (ironically, none of the members on the Vegas trip have an M.B.A. degree) all run businesses with between $1 million and $100 million in annual revenue, most of them selling products like vitamins or exercise guides or acting as affiliates and placing ads for products sold by other people. Each is admitted to the group by Silver with the understanding that they'll be candid about their businesses, even though some members might be direct competitors.

For most of the Mavericks, the main payoff is being able to discuss business with peers who have grappled with the same problems as them. This has particular value to M.B.A.'s participants because of the mostly solitary nature of running a small business online.

During the first day's business session, Jim Sweeney, owner of Honesteonline.com, which helps to validate Web merchants, explains how he's discovered some sales rules that apply regardless of the product. For instance, the price point $39.95 grosses more and sells more units than either $29.95 or $49.95. ("I found the same thing—different marketplace too," says Silver.)
