There’s no doubt that online ticketing platform Eventbrite is growing like gangbusters. The platform is on track to sell $400 million worth of tickets this year, which is double the $207 million it did last year. The company could reach $1 billion in gross ticket sales in 2012. And part of Eventbrite’s future plan will include a public offering. Co-founder Kevin Hartz tells ZURB in a recently published podcast that Eventbrite could file to go public as early as late 2012 (at the 38 minute mark in the podcast) if the company reaches certain performance benchmarks.
