WindLogics is headquartered in St. Paul, but they have an office in Grand Rapids, MN. This article discusses the company. And here's their website.
Basically, they analyze the wind potential of a certain area to help determine the viability of a wind farm in that area. There will be a great deal of wind farm expansion in Minnesota and Wisconsin in the next several years (at least), and it looks like WindLogics is in a good position to feed off of that growth. Too bad it's not a publicly-traded company.
