This morning, just under a year later, Sadoun took the stage at the Publicis-founded VivaTech conference in Paris to unveil long-awaited details about Marcel, beyond the ad lingo boilerplate of transformation, innovation, and breaking down silos. There was still a lot of that, but also a walk-through of what the company is calling "Publicis in the palm of your hand." Built with the help of Microsoft AI and the company's own Publicis.Sapient, the new platform aims to connect all 80,000 Publicis employees, across 200 disciplines in 130 countries, to provide more seamless communication, collaboration, and anticipation of client needs. It's currently being beta-tested by 100 employees, moving to 1,000 in the next few weeks, and the idea is to start the overall rollout in January, with a goal of having 80% of the company's people connected by 2020. "When I announced this last year at Cannes, our industry was dancing, drinking, and having fun. But since then, a few things have happened," says Sadoun, in a conversation with Fast Company before the VivaTech presentation.
