He left the Mercury News in January 2005 to work on a grassroots journalism project, called Bayosphere, launched in May 2005. After closing Bayosphere, Gillmor moved on to a new project, the Center for Citizen Media, a non-profit organization affiliated with the University of California, Berkeley's Graduate School of Journalism and the Berkman Center for Internet & Society at Harvard University Law School.
In 2007, Gillmor co-founded Dopplr, an online travel application project.
In November 2007, Gillmor was named founding director of Arizona State University's new Knight Center for Digital Media Entrepreneurship at the Walter Cronkite School of Journalism and Mass Communication. Dan Gilmor is a board member of the Global Editors Network since its creation in April 2011.
