Word on the Spy line is that Thierry Dumoulin, managing director of Saatchi & Saatchi X’s New York office, is no longer with the agency. Phone calls are leading to broken extensions and sources are saying Dumoulin’s departure leaves no one officially in charge at X NYC. Anyhow, Dumoulin has held the MD title for two years at the New York office of Saatchi’s shopper marketing unit.  Prior to his gig at X, the exec spent two years at JWT London as an international account manager and six after that as director of client services at fellow UK operation, Imagination.
