In the 1990's, Daou was a sought-after producer, keyboardist, and engineer, featured on recordings by Bjork, Miles Davis, Janet Jackson, Diana Ross, and Mariah Carey, among others.
Daou became a political blogger after the 2000 election. His 2005 article, The Triangle, was described as “a seminal essay on the interaction between the blogosphere, the political establishment, and the press.”
Daou was among the first internet staffers to work in a presidential campaign war room, directing online outreach and rapid response for John Kerry’s 2004 campaign. In 2006, he became Hillary Clinton’s senior digital strategist and was later named Internet Director for her 2008 presidential run.
