Winder Hughes, co-founder of Hi-Fi, a social network he says brings hashtags to life, decided to let a video do most of the talking.

"We knew that that would be a very short way of really distilling the whole concept down where everyone that would walk by or listen to it they could easily get it," Hughes said.

He said it's a presentation that almost didn't happen.

"At first we weren't going to sign up at all for One Spark, but that was a good thing that we did because it really rallied our whole company around moving everything forward," Hughes said.

Between Wednesday and Sunday every creator at One Spark will get their chance on stage.

For Shimmy Chic Fitness, that day is Friday. And the belly dance class instructors say they'll be bringing the same interactive energy from the street to the stage.

"We want them to take away that belly dancing is not just for the dancers on stage, that anybody can do it, that it's a lot of fun," Rafaella Degracia said. "It's a great workout."
