Omnicom has named Christine Gambino as Chief Executive Officer of Omni with immediate effect. She replaces Duncan Painter, who is stepping down to take up a senior executive role in the United Kingdom, his home country.
Gambino previously served as Chief Operating Officer of Omni, where she led operations for a team of over 1,000 product and technology professionals. The team is focused on developing Omnicom’s marketing and sales intelligence platform.
Prior to Omni, Gambino spent six years at Flywheel. There, she led engineering, product, and data science teams and drove key innovations in automation and predictive analytics. She previously held roles at Under Armour, UPS, and CasSevern.
“It’s an honour to lead Omni at this pivotal moment when the platform is serving as a shared resource for the new Omnicom,” said Gambino. “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.”
Omnicom Commerce, also previously under Painter, will now be led by Alex McCord, who will oversee its operations and growth while continuing as CEO of Flywheel. McCord has 15 years of experience in the commerce industry.
“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,” said Painter. “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.”
Omni and Flywheel will continue to operate as a core part of Omnicom’s Integrated Media capabilities.
