PUTEAUX, France, Dec. 11, 2012 /PRNewswire/ -- Following their recent successful rebranding, Havas Worldwide announced today that Matt Weiss will join the network as Global Chief Marketing Officer. In his new role, Weiss will work closely with key leaders across the Havas Worldwide network to drive growth for the agency and its clients. Based in the New York office, Weiss will officially begin his new role in January 2013. "Matt joins our team at an exciting time for Havas Worldwide: We're coming off one of our strongest ever years for new business. The rebrandinghas underscored our unique integrated structure and digital-at-the-core model while acting as a real growth accelerator," said Havas CEO David Jones."Matt's experience working with some of the world's largest and most innovative brands will be a huge asset in driving our clients' businesses forward and with it our own growth. He has an impressive track record in winning new business, gets both brand and digital, and shares our enthusiasm for the enormous opportunity that the digital revolution presents to our clients and our own business." Weiss joins the network just three months after Havas renamed its 316 offices to Havas Worldwide. This operation was a major success and drove momentum in the business around the world. In the last two months the company has won Louis Vuitton globally, Berluti globally, Diet Coke in Europe, the European Central Bank, and La Poste together with the global Unilever data business. Weiss replaces Naomi Troni, who was recently appointed CEO, Havas Worldwide Southeast Asia. Troni has worked within the network since 2004 in various roles in the UK and the US and is a member of the Havas Worldwide Executive Committee. In taking this position Weiss commented, " I was drawn to the scope and scale of Havas Worldwide and their unique position as being one of the most agile, collaborative, and digitally innovative of all the global networks. Equally intriguing is their unique view of the changing marketing landscape - a deep understanding of how social media and corporate responsibility are intrinsically linked to drive business results for clients." Weiss is not a newcomer to global marketing, having spent eight years at McCann Worldgroup, first as new business director for McCann NY and then as Chief Growth Officer for the network. In that time he was credited with bringing significant wins to the agency such as Intel, Nikon, Verizon Wireless, Holiday Inn, and Weight Watchers, to name a few. Prior to that he was part of the pitch winning team that brought MasterCard's "Priceless" campaign to market. For four years he ran that business—first domestically and then globally—forming the founding US team credited with work that won almost every creative award in the business.
