Omnicom appoints Christine Gambino as Omni CEO

Omnicom has named Christine Gambino as Chief Executive Officer of Omni, effective immediately, marking a leadership transition for its marketing and sales intelligence platform.

Christine Gambino succeeds Duncan Painter, who is stepping down to take on a senior executive role in the United Kingdom. The appointment places a long-time operational leader at the helm as Omnicom continues to scale its integrated data and technology offering.

Leadership transition at Omni

Christine Gambino previously served as Chief Operating Officer of Omni, where she managed operations for a team of more than 1,000 product and technology specialists. In her expanded role, she will oversee the platform’s development and adoption across Omnicom’s global network.

Her experience spans leadership roles at Flywheel, as well as positions at Under Armour, UPS, and CasSevern, with a focus on engineering, product, and data-driven innovation.

Christine Gambino, CEO, Omni: "It’s an honor to lead Omni at this pivotal moment when the platform is serving as a shared resource for the new Omnicom. Duncan has created an exceptional foundation, and I’m grateful for his partnership and leadership as we now accelerate adoption across the organization. I look forward to ensuring teams across every discipline can leverage Omni’s integrated capabilities to deliver measurable impact for clients."

Changes extend to commerce division

Alongside the leadership change, Omnicom has appointed Alex McCord to oversee Omnicom Commerce, while continuing in his role as CEO of Flywheel. He will focus on driving growth by combining technology, data, and commerce strategy.

The move reflects a broader effort to strengthen Omnicom’s commerce capabilities and align them with its integrated media and data infrastructure.

Duncan Painter, former CEO, Omni: "I’m proud of how swiftly we launched the next generation of Omni following the Interpublic acquisition, establishing it as a unified asset for the combined group. Christine was central to that effort and brings a deep understanding of the platform to drive Omni to its next phase. Additionally, Alex has been instrumental in shaping Flywheel into an industry leader and brings deep commerce expertise to strengthen Omnicom Commerce. I have complete confidence in both of them to accelerate impact across Omnicom as I move into my next chapter in the UK, where I’ll be closer to my family."

Focus on platform growth and integration

Omni and Flywheel remain central to Omnicom’s integrated media offering, supporting data-driven marketing and commerce strategies for clients.

With Christine Gambino’s appointment, the company signals continued investment in its platform-led approach, aiming to enhance collaboration across teams and deliver measurable outcomes through unified data and technology.
