There is no restriction on the type of idea a creator can submit, but it’s important to remember this is about moving an idea forward. The community votes on the ideas that will be presented at the event. The selected creators explain a $5,000 step that will move the idea forward, and will meet people who can help.
Just having an idea is not enough. You are the one pushing it into existence, so be clear about what’s needed for that next $5,000 step.
Presenting the ideas is only part of the night. Part two is at the reception to find out the winner. Have a beer, talk about ideas. That part of the evening is the whole reason we put on the event.
