From the event site:
Join us this spring for the largest Hackathon series, ever. Over 30 cities and 6,000 developers will join in to build stronger developer ecosystem around the world.
What makes AngelHack the best hackathon series on the planet?
Never been to a hackathon? Here’s what you can expect
Acceptance into Spring 2014 HACKcelerator program
HACKcelerator is a global pre-accelerator program designed to help top hackathon teams turn their hacks into market ready products. If you win AngelHack you win our full support for whatever product you’d like to have us help you develop. You’re in. We’ll provide you the platform for connecting with amazing mentors and a series of events in Silicon Valley to connect with investors and media. This will be your shot at glory. Learn more on HACKcelerator program here.
What should I build?
We want to see new projects that can wow the crowd and have the potential to improve peoples lives. Hacks that people would use, laugh at, and potentially scale.Have fun, try to finish in time, and show us an awesome demo!
Who should attend?
Junior developers looking to improve their skills, senior developers looking to jive with budding members of the community, designers of all skill-sets, and serious entrepreneurs that can add value to teams. Never built with a specific language before? Fear not, we’ll do our part to have teachers on hand throughout the hackathon to help you get going with these new and needed skills.
How is it judged?
We’re doing things a little different this time. Say goodbye to power-points. That’s right, no power-points whatsoever. To present at AngelHack you must DEMO. Period dot the end. And everyone who wants to win AngelHack will have to demo their product for at least 30 seconds. Projects will be judged on a combination of originality, technological difficulty, viability and usefulness. We want to see new ideas, ideas that are useful, ideas that solve big problems, ideas that could potentially make money and ideas that get people excited.
