I'm surprised I haven't heard of any seed accelerator programs in the Twin Cities yet. It's a great area to live in, and MN has some of the sanest governance to be found in the U.S.
There's also the Minnesota Cup; I haven't heard many success stories emerging from it, but I haven't looked into it very hard, either: http://breakthroughideas.org/
There's a great tech community in & around the Twin Cities, and definitely more and more interest and activity toward building a startup culture in this area. Cool stuff is going on.
