Overflow began as a dream in 2008. In 2009, we incorporated as a nonprofit. Then in 2010, we discovered L3C (low-profit limited liability company) is more in line with our model so we shut down the nonprofit and restarted as an L3C. We became the 17th L3C in the state of Illinois. On March 18, 2011 we opened our doors to the public at 1550 S. State Street.
