YUNNO

Yunno is a “social engagement platform” that facilitates contests for brands looking for another marketing channel. For example, Chicago Bulls swingman Kyle Korver is using Yunno to ask users to submit their favorite Chicago meal for a chance to win $200. After entering the contest, Yunno then asks users to become a fan of Korver’s Facebook page and offers the option to push the contest entry to Facebook while awarding Foursquare-like badges for entering. The business model: All of the company’s current clients are free trials, but the company sees the pricing being based on a cost-per-engagement model. Yunno is currently chasing Zappos, Urban Outfitters and other clients.
