On a very snowy Thursday, February 8th, hundreds of techies, designers, investors and entrepreneurs descended on the Pantages Theater to attend Minnedemo31. Minnedemo, held three times a year, is the premier showcase for working technology products and tech innovation in Minnesota.

The formula for our ‘geek show and tell’ is simple: 7 presenters, 7 minutes each, live demos of working tech made in MN. This time around we were proud to highlight 7 incredible groups. Be sure to check out their demos below!

We are always looking to improve the quality and experience of our events, so we want to know: what would you like to see from Minnestar? What is your vision for our tech community and how can Minnestar help us get there? Shoot us an email any time (we love hearing from you!) at support@minnestar.org.

See you at Minnebar14 April 27th at Best Buy Corporate HQ!
