Droga has been working on the project for the past three months with Maurice Levy, the chairman of Publicis Groupe. No further details have been released.
Droga said: "I am extremely proud of what we have achieved at Publicis, but I have reached a point in my career where I want to establish a blueprint for my own creative business. I am very excited about this new endeavour. But my first priority is to see through several large projects and ensure a smooth transition."
