eeventeEvent, a startup that demonstrated at the Launch conference today in San Francisco, is looking to take on services like Eventbrite by offering organizers a new way to promote their events.

The company offers a full platform for managing your event, with features like an event website builder and ticketing, but the most interesting feature is the Ambassador program. It turns every attendee into a potential event promoter by offering prizes to people who encourage their friends to attend. So if you grow the attendance at an event, you could earn badges on the event site, and even better, real-world prizes like VIP seating and free parking.

One of the Launch judges, Naval Ravikant of AngelList, said that other event sites including Involver have tried similar programs and they run out of steam very quickly. It’s a cool idea, but people start getting annoyed and ignoring what they see as spam from these so-called ambassadors.

eEvent has been available for a month and the company says it has already been used for 350 events in the United States.
