Brand MarketingBig Fuel CEO Jon Bond Leaves AgencySpark's Zasky is new presidentBy Noreen O'Leary|October 9, 2012ShareBy Noreen O'Leary|October 9, 2012Share Big Fuel chief executive Jon Bond has left the social media agency, where he was in that role for 22 months. The Kirshenbaum Bond Senecal + Partners co-founder and former CEO joined Big Fuel in January 2011 after making an investment in the company. Publicis Groupe acquired a 51 percent stake in Big Fuel in July 2011 and the current management change is part of a closer alignment of Big Fuel with Publicis’ Starcom MediaVest Group. Big Fuel was previously associated with the holding company’s VivaKi unit, which specializes in digital media. As part of the shift in top management, Ken Zasky, the president and a founder of Spark, a SMG media agency network, will move to Big Fuel as president. Avi Savar, the shop’s founder and chief creative officer, continues in that capacity as does Mike McGraw in his job as Big Fuel’s chief operating officer. When Bond joined Big Fuel, the agency’s largest client was General Motors and seven months later Publicis Groupe said it was buying a stake in Big Fuel, largely because of both companies’ relationship with the automotive giant. By December of that year, Big Fuel had been cut from GM’s agency roster. The agency now includes Starwood, T-Mobile and Chase among its clients. Adweek Adweek
