September 15th marked the last day of the program for Tumml's Summer 2014 Cohort! To celebrate their hard work, Tumml hosted an Exhibition Day, featuring presentations from each of the entrepreneurs and a community mixer. The event was a huge success, with 150+ guests (including community leaders like the President of the San Francisco Board of Supervisors and investors from firms like Version One Ventures, Andreessen Horowitz, DBL Investors, etc.) learning about the work of the amazing urban impact entrepreneurs. We are so sad to see our Summer Cohort go, but we know that they're all going to do great things... and be coming to a city near you! #urbaninnovation
