Lanctot rose up through the ranks at Razorfish through Avenue A, stuck with it through an awkward stint at Microsoft and then for a time left the agency for a platform-side job at the software giant. He returned to Razorfish in a global media-sales role in 2011.
Today, he serves on several startup advisory boards, including Placed and TapJoy.
Lanctot's is the latest in a string of senior digital talent to jettison from Publicis-owned agencies. Among the other recent departures, detailed in a story here last week, are Colin Kinsella, former CEO of Digitas North America, Digitas CEO Laura Lang and Rosetta CEO Chris Kuune (who remains chairman).
