Seventeen projects will get that chance as the latest recipients of Prototype Fund grants from Knight Foundation. The Prototype Fund is designed to give people with great concepts for media and information projects grants of $35,000 and six months to take their idea all the way to demo with a class of others facing a similar challenge. What can you learn in six months? Quite a bit. Recently, grantees, friends and advisers gathered at Matter in San Francisco to watch presentations from Knight grantees completing their Prototype Fund grant experience. The event focused on highlighting learnings from projects started six months earlier. In the case of this group, we learned how youth can learn about fair use to become little Jon Stewarts, how live video can engage radio audiences, and how sometimes, despite technological advances, parts of your community might prefer a paper map. The presenters talked about how they tested assumptions, addressed technical challenges and worked to understand user needs. We fully expect some of the grantees will move on to further funding from Knight Foundation and other sources. Two of the projects from the recent class have already secured outside funding. Max Ogen’s DAT has received a grant from the Sloan Foundation and will become a project of the Open Data Institute, and 596 Acre’s Living Lots project has received an OpenGov grant from the Sunlight Foundation. In all 17, projects presented at demo day: The Rashomon Project, Curious City, How Secure Am I?, DocHive, WFMU, CollabMatch, Transom Online Workshops, Radiotopia, VoteStream, Kon*Fab, Data Docs, DAT, FOIA Machine, Living Lots, OnBoard and Media Breaker.
