Topic - Eventbrite

Eventbrite is a global marketplace for live experiences that allows people to find and create events in 190 countries. The platform allows event organizers to plan, promote, and sell tickets to events (event management) and publish them across Facebook, Twitter and other social-networking tools directly from the site's interface. The company generates revenue by charging organizers a fee of 2.5% of the ticket price plus 99 cents per ticket sold, but does not charge any fee for free events. - Source: Wikipedia
