Executive MBA students took turns in the “Terp Tank,” pitching their businesses to seasoned investors like on TV’s “Shark Tank.” The panel of five investors was impressed with the business ideas from the 16 teams and some of the pitches may lead to investments. The Oct. 16 pitch session was the culmination of the EMBA entrepreneurship Action Learning Projects, which started in April 2015. The projects are part of a course taught by Joe Bailey, associate research professor, and Elana Fine, managing director of the Dingman Center for Entrepreneurship. It wraps up later this month.
