One of the world's largest communications companies, Publicis Groupe includes in its portfolio such iconic advertising agencies as Leo Burnett and Saatchi & Saatchi. In today's connected world, in which it must rapidly serve multiple audiences across divergent cultures and demographics, the holding company, Sims-Williams says, is focused on "it's Power of One positioning—allowing people to utilize, think, and be free to put forth ideas, and let their creative juices flow without being constrained by agency silos." She further states that Publicis Groupe has made a commitment to using artificial intelligence to help connect its people to one another and to opportunities across the globe. Called Marcel in honor of the company's founder, Publicis Groupe's AI platform is currently in development and being built on the foundation of four key pillars: "knowledge, connectivity, opportunity, and productivity."
