100state, a new co-working hub downtown, is hosting a free event for entrepreneurs 7-9 p.m. Friday, June 7 at its office at 100 State St.

Called “Entrepreneurial Problem-Solving Soiree,” the event will match attendees with a group of innovators and present them with a problem in Madison. Each group spends 20 min. developing a solution. Afterward, attendees will work with 100state to implement their best ideas.

Attendance is limited to 100 people. Following the problem-solving portion of the evening will be a party that’s open to the public.
