In the office suites below the Washington Street parking garage near State, student entrepreneurs from the University of Michigan and their mentors have gathered for a meeting, where they present business ideas in a setup similar to an art gallery. The atmosphere is hushed, thoughtful. The ubiquitous Zingerman’s catering elves have come and gone, leaving pound cake and coffee. Attendees mill around examining the structure for each business on the walls. At the end of the meeting, the posters and papers are covered in little stickers and notes of feedback.
