Speaking to Media, Gallate said that his work in Asia was largely complete after turning the agency's regional operations around since his arrival in 2005.
Gallate will retain his leadership role at digital arm Euro RSCG 4D, moving into the global chairman position.
The New York start-up, added Gallate, would be a "fully integrated agency, with digital at its core", focusing on the B2B and B2C requirements of technology clients, and leveraging Gallate's experience with such clients as Intel, Dell, IBM and Apple.
