For the past three years, Urban Innovation Exchange has been following hundreds of small projects making a big impact in Detroit. We have covered everyone from corporate executives working to create stronger communities to grassroots organizers galvanizing people on the streets. They've ranged from tech start-ups to restaurateurs, spiritual leaders to youth advocates, artists to ambassadors. Three years and some 300 people later and we can say: this is the face of Detroit innovation. Video by DETROIT LIVES!
