Florian Adamski appointed CEO of Omnicom Media Group

As part of Omnicom’s sweeping post-merger restructuring, Florian Adamski has been named CEO of Omnicom Media, now overseeing OMD, PHD, Hearts & Science, Mediahub, Acxiom and the newly added Initiative and UM, a remit that significantly expands his global media responsibilities.

Adamski has been CEO of Omnicom Media Group since 2021, following a four-year tenure as CEO of OMD Worldwide. Before that, he led Omnicom Media Group Germany from 2015 to 2017. Across these roles, he has been central to Omnicom’s global media strategy and its evolution through successive waves of industry transformation.

With more than 25 years in and around the media business, Adamski often credits an early piece of advice for shaping his leadership approach: success hinges on learning faster and acting faster than the competition. He argues that this principle is even more crucial today as the media's role in consumers’ lives undergoes a fundamental reset. Under his leadership, Omnicom’s agencies increasingly operate through the Omni open operating system, enabling teams at Hearts & Science, OMD and PHD to surface insights at speed and respond to shifting consumer behaviors with agility.

Adamski positions Omnicom Media Group as the global hub powering this collaboration across 20,000-plus specialists. The group’s mandate, as he frames it, is to equip teams with bold talent, advanced tools and technology that enable “connection with intention”, creating meaningful consumer moments that translate into long-term value for brands. This philosophy underpins Omnicom’s broader integration strategy, shaped by Adamski’s steady progression across leadership roles in Germany, the UK and the US. The continued consolidation under his watch places him at the forefront of navigating one of the largest transformations in global media, as Omnicom aligns its agencies around a unified, data-led vision for the future.

The most anticipated merger in the ad industry - Omnicom’s acquisition of Interpublic Group, formally closed in late November 2025, creating the world’s largest marketing-services holding company and folding IPG’s media assets into Omnicom’s media arm. The deal has set off a comprehensive reorganisation, with Omnicom outlining a refreshed leadership structure and a plan to integrate agencies and platforms under the Omni operating system while retiring or consolidating several legacy brands.
