Like most freelance jazz musicians, John Knific was always searching for his next gig. While attending classes at Case Western Reserve University, the student supplemented his income by playing in trios at restaurants. When Knific looked at ways to promote himself on the Internet, he found that the available tools were woefully lacking. He was looking for something like a LinkedIn for musicians. The model didn't exist -- so he created it. Founded in 2008, CitizenGroove allows artists to work with numerous people on various projects, making static portfolio pages inadequate. CitizenGroove's dynamic platform links musicians to all the artists with which they have collaborated.
