Guy Marks


Guy’s career began in the digital, mobile and AdTech world. He jumped swiftly into the start-up scene, culminating in back-to-back sales of two agencies. Omnicom Media Group’s acquisition in 2014 brought him into the holding group and since 2018, he has been at the helm as CEO of OMD, the world’s largest media agency. Guy brings a start-up mentality to the EMEA region, delivering both client and agency transformation. He considers himself technology driven but is motivated by human insight and creativity.
