In 2009, Joseph founded The Zeitgeist Movement, a self-described "sustainability advocacy organization." It was originally started as the "activist arm" of an organization called The Venus Project, launched by Jacque Fresco in 1994. In 2011 the two organizations separated. Joseph's work with the Movement and the Trilogy has been the subject of national media attention to include articles in The New York Times, The Palm Beach Post, VC Reporter, and TheMarker.
