“Y Combinator-backed Eventjoy, a service that makes it easier to organize events using online and mobile tools, is officially making its debut today, offering support for online ticketing, event websites, mobile event apps, Twitter walls, and more. The company, previously known as EXMO, had in the past been more focused on its mobile application for event organizers, but is now working to offer a complete solution that can handle everything from accepting payments to polling users after the event has wrapped.”
