PublicisLive will focus exclusively on the most prestigious international conference and corporate events in the world, particularly in Europe and the Middle East. The company has been set up to meet the demands of governments, institutions and corporations, for high-end events.
Attias has built up Publicis Events Worldwide over the past ten years and will now focus on the top end of the business. He will retain a handful of clients, including the World Economic Forum.
Maurice Levy, chairman and chief executive of Publicis Groupe, said: "Richard is one of the most creative and entrepreneurial forces within the Publicis Groupe family, and he has turned Publicis Events Worldwide into an extraordinary force in the global events field.
"I am delighted that Richard can now devote himself to the most challenging but also most rewarding segment of this market as a real partner of Publicis Groupe. I have every confidence that PublicisLive will be a success, for the Groupe and for Richard."
PublicisLive will be independent of the Publicis Events Worldwide network and its offices in France, the US, Austria, Germany and Asia Pacific. However, the two will be part of Publicis Groupe's specialised Agencies and Marketing Services division, which is headed up by John Farrell.
Attias added: "PublicisLive has absolutely no equivalent on the market, thanks to the quality of its teams, to its size, and to the strong relationships we have built up over the years."
