Spot.Us was a non-profit organization designed to bring citizens, journalists, and news publishers together in an online marketplace based on crowdsourcing and crowdfunding methods and principles. It was founded in 2008 by David Cohn, who received a $340,000 grant from the Knight Foundation to pursue his idea. In November 2011 it was bought by American Public Media. They hosted the site for a time, but were unable to maintain it. It was retired February 2015.
