A trio of University of Dayton students knows just how hard it can be to find a great job opportunity. So in early 2010 they launched a new company, Brain Rack, that matches creative students with companies through the emerging crowd sourcing problem solving model. Here's how it works: A company or organization poses a question seeking an innovative answer to college students. Students submit answers to the question for company review. The company awards a cash prize to the best, and then has the opportunity to interview these students for a job. The challenges also are open to recent college grads. In 2010, BrainRack won second place in the University of Dayton's Business Plan Competition and $10,000. It also took second place honors in the Midwest pool at the winner-takes all Harvard Business School Alumni New Venture Competition.
