Eventbrite

Where it started: A co-working space

Eventbrite is an online service for event registration and ticket sales that aims to "bring people together." Maybe it's appropriate then, that the company began in a space that brought together entrepreneurs from other tech start-ups like TripIt, Flixter, Boxbee, and Zynga. Eventually, the Eventbrite team outgrew the space and moved into an office of its own that boasts an open floor plan and a communal cooking and dining space.
