Hackathons are marathon competitions that attract software developers and entrepreneurs. 

Brandon Weber is with The Urban Hive on H Street which is hosting the "AppHack."

On Insight with Beth Ruyak, Weber said the event will draw a mix of people working in a variety of environments.

"Some people will have already created a team and already have an idea that they want to present. Other people will come with certain skills and are looking to put together with a team. Some people have an idea and they're looking for coders and designers. And some people are coders and designers and want to be part of a great team but maybe don't have the idea fully formed."

A panel of judges will rank the teams at the end of the event.

"The winner will actually have the opportunity to be a part of Global Demo Day," explains Weber, "in which they're able to present to 150 Silicon Valley investors which is an incredible opportunity. So it's not just a 'hey come play around for the weekend.' Although it's going to be a lot of fun. But they're actually creating and building something that solves problems.

The AppHack starts tomorrow at 9 AM and ends Sunday at 6 PM.
