Headquartered in downtown Minneapolis, this upstart marketing company makes its services with 100 percent sustainable resources. It takes some creativity: Ads are mowed into grasses, stamped into the snow, written in chocolate on edible apples, or drawn on glass with a proprietary and natural formula that wipes off with a sponge. Übergrün counts as clients some of the biggest companies in Minnesota, America, and the world: Mayo Clinic, Hyundai, 3M, General Mills, and Virgin Mobile, to name a few. Those corporations can afford the most expensive marketing materials, but by partnering with Übergrün, those mega brands get a nice boost of feel-good green business. Let’s hope they’re only the beginning.
