FiLife, the IAC-Dow Jones (NYSE: NWS) personal finance joint venture, is flipping top execs: Dave Kansas, who signed on in early 2007 when the venture didn’t have a name, is stepping aside as president for an editor-at-large role. In his place, Ezra Kucharz, the former Oberon Media EVP and iVillage COO. Kucharz was restructured out of Oberon in June after a little more than one year in the job. He starts at FiLife in December. (Portfolio.com reported the Kansas departure first while MediaMemo had Kucharz.)

When he joined the JV, Kansas was editor of the WSJ’s Money & Investing section—he’s writing a book on the subject now—and helped launch TheStreet.com (NSDQ: TSCM). But FiLife took more than a year to get off the ground, going public in August 2007 and finally launching officially in June 2008. By contrast, IAC’s solo site The Daily Beast from TIna Brown took less than half the time to move from green light to launch.
