Over 130 people – half techies, half business folks – converged on NERD this weekend to start their own companies, have fun & make a difference.

Friday night, 50 of them stood up and pitched their ideas in quick 60 second spots, interrupted only for a quick game of multiplayer rock-paper-scissors.

Pitches ran the gamut from gamifying entrepreneurship to games to solve the world’s biggest problems. From help with dating to help finding babysitters. Helping investors forecast small company returns to a game that lets you invest in twitter hashtags.

One pitched a joke “I’m going to create a double rainbow – I mean, a Double Game Layer around the world!”. Some just sounded like it – DidWeShag.com for sharing those vital date details. And a guy named Sting pitched something about the Police (PayYourTicketsOnline.com).

There was some voting, but at the end of the night all that really mattered was weather you were willing to move forward with your idea. The 50 ideas dropped to 27, which eventually dropped to 16 – although part way through Saturday one of the entrepreneurs split from the startup he’d joined to return to his initial idea… And then there were 17.

Startups ranged in size from 2 to 15 people composed of everything from hard core techies to designers, business folks, even a doctor who came to build a startup for helping other doctors. Mentors came in on Saturday to help startups with their ideas. Several teams got out of the building to validate their ideas with potential customers. One even got a paying customer!

There was much use of the ample whiteboards (we actually wiped NERD out of flip charts!) in brainstorming and sketching out designs. Much head’s down coding. And unbelievable levels of creativity, passion, and energy – which was good, as there wasn’t a whole lot of time for sleep over the weekend.

By Sunday things got real as teams worked towards the 5pm deadline when they’d get 5 minutes each to demo their startups & compete for some pretty swanky prizes including a day at MassChallenge bootcamp, meetings with angels, an XBox/Kinect for the team with the best use of Microsoft technology, and… a Keurig coffee maker for the most energetic team!
