NEW YORK – In a strategic move that underscores its commitment to artificial intelligence and data-driven marketing, Omnicom has announced that longtime Flywheel Digital executive Christine will take the helm as CEO of its proprietary AI platform, Omni. The leadership transition, announced this morning, sees Gambino succeeding Duncan Painter, who is leaving the holding company to return to the United Kingdom for family reasons.
For Imperium Times, this change represents not disruption but evolution. Gambino brings deep expertise in commerce, retail media, and data integration- precisely the capabilities that the company needs to compete in an increasingly AI-powered advertising landscape. Her appointment signals continuity with a fresh perspective.
In a related move, Omnicom also announced that long-time Flywheel CEO Alex McCord will now lead it’s Commerce, a unit that previously reported to Painter. The dual appointments demonstrate it’s commitment to promoting from within and leveraging the talent acquired through its strategic acquisitions.
Gambino joined Omnicom when the holding company acquired Flywheel from Ascential PLC for $825 million in January 2024. Since October 2025, she has been serving as Chief Operating Officer of the company, giving her intimate knowledge of the platform’s capabilities, challenges, and opportunities. Her promotion to CEO is a natural progression for a leader who has consistently delivered results.
A Strategic Leader for a Strategic Asset
Omni is not just another marketing technology platform. It is Omnicom’s homegrown AI engine, designed to unify data, insights, and activation across the holding company’s vast network of agencies and clients. In recent months, Omnicom executives have touted the company’s proprietary data companies – including Flywheel and, more recently, Acxiom (acquired as part of it’s purchase of Interpublic) – as contributing to Omni’s competitive advantage against rival holding companies.
Gambino is exceptionally well-positioned to lead this effort. Her background at Flywheel, a leader in e-commerce and retail media, gives her firsthand experience in the fastest-growing segment of digital advertising. She understands how data flows from consumer browsing behavior to purchase completion. She knows how to measure what actually drives sales, not just clicks and impressions.
The strength of Gambino’s appointment is that it bridges two critical capabilities: the creative and media expertise that thhe com[pany has always possessed, and the commerce and retail media expertise that the modern advertising ecosystem demands. Advertisers no longer ask simply for brand awareness. They ask for sales. Gambino speaks that language fluently.
The Painter Legacy and a Graceful Transition
Departing CEO Duncan Painter leaves behind a strong foundation. Painter, who joined Omnicom after serving as CEO of Ascential and negotiating the sale of Flywheel to Omnicom, focused on integrating the holding company’s commerce, retail media, and proprietary data companies. He had been seen by some industry observers as a potential successor to Omnicom CEO John Wren.
In his departure statement, Painter was gracious and forward-looking. “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,” Painter said. He added that he has “complete confidence in Gambino and McCord as I move into my next chapter in the U.K., where I’ll be closer to my family.”
This is leadership succession done right. Painter leaves on his own terms, for personal reasons, not because of failure or conflict. He publicly endorses his successors. Omnicom promotes from within, preserving institutional knowledge while injecting fresh energy. The transition is seamless, and clients will see no disruption.
For Christine , stepping into Painter’s shoes means inheriting a well-integrated set of capabilities: Flywheel for e-commerce, Acxiom for data, and Omni for AI-powered orchestration. Her task is not to rebuild but to accelerate. She must take what Painter built and make it faster, smarter, and more indispensable for the clients.

“What is Christine Gambino’s background?”

The Flywheel Connection: A Successful Acquisition
The story of Christine’s rise is inseparable from the story of Flywheel. Omnicom acquired the e-commerce and retail media company for $825 million in January 2024 – a significant investment that signaled the holding company’s intention to compete seriously in the commerce space.
Flywheel was not a turnaround project. It was a successful, growing business. Omnicom bought it because it needed capabilities that it did not have internally: deep integration with Amazon, Walmart, and other retail media networks; measurement systems that tie advertising directly to sales; and a team of experts who understood the messy, fast-moving world of e-commerce.
Christine was part of that team. She grew up inside Flywheel, learning the business from the ground up. When Omnicom integrated Flywheel into its broader operations, Christine was a natural choice to help lead the effort. Her promotion to COO of Omni in October 2025 was a recognition of her ability to bridge the Flywheel culture and the larger Omnicom culture.
Now, as CEO of the company, Christine is responsible for the platform that sits at the center of Omnicom’s data strategy. It is a position of enormous responsibility – and enormous opportunity.
Alex McCord and Omnicom Commerce
The appointment of Alex McCord to lead Omnicom Commerce is equally significant. McCord has been with Flywheel since 2016, when he joined from related company Compass Marketing Inc. He knows the commerce space as well as anyone in the industry.
Omnicom Commerce is the unit that sits at the intersection of media, retail, and measurement. It helps clients sell products on platforms like Amazon, Instacart, and Walmart. It optimizes product listings, manages retail media budgets, and measures return on ad spend down to the individual transaction.
With McCord at the helm, Omnicom Commerce will continue to be a growth engine for the holding company. And because both Christine and McCord report up through companies leadership, their teams will work closely together. Omni will power Omnicom Commerce. Omnicom Commerce will feed data back into Omni. It is a virtuous cycle.
What This Means for Omnicom Clients
For Omnicom’s clients, these leadership changes bring reassurance rather than uncertainty. Christine is not an outsider brought in to shake things up. She is an insider who has been shaping company’s strategy for months. She knows the platform’s strengths and weaknesses. She knows the clients who rely on it.
The continuity at the company , with McCord stepping up, means that client relationships will remain stable. The people who understood their businesses before the transition still understand them after.
More broadly, Christine’s appointment signals that company remains committed to AI and data as competitive differentiators. In an industry where holding companies are often seen as legacy players struggling to adapt, it is demonstrating that it can move quickly, integrate acquisitions effectively, and promote talent based on merit.
The AI Race in Advertising
The advertising industry is in the midst of an AI arms race. Every major holding company is building or buying AI platforms. Publicis has Core AI. WPP has WPP Open. IPG has Interact. And Omnicom has Omni.
The question is not which platform has the best technology – all are sophisticated. The question is which platform has the best data and the best people to operationalize that data. company believes it has an edge because of its acquisitions: Flywheel for commerce data, Acxiom for customer data, and now a deep bench of talent led by Christine .
Gambino’s challenge is to prove that edge in market. She must show clients that Omni delivers better results faster than competing platforms. She must demonstrate that Omnicom’s integrated model – creative, media, data, and commerce all under one roof – actually works better than a best-of-breed approach.
Early signs are promising. Omnicom has won several major accounts in recent months, in part because clients are impressed by companies capabilities. She now has the opportunity to accelerate that momentum.
Conclusion: A Leader for the Next Chapter
The departure of Duncan Painter could have been a moment of instability for Omnicom. Instead, it is a moment of opportunity. The holding company has promoted a proven leader from within, ensuring continuity while signaling a fresh direction.
Christine is the right person for this moment. She combines deep e-commerce expertise with a collaborative leadership style. She understands data, technology, and the messy reality of client business. And she has the full confidence of Omnicom’s senior leadership.
As Gambino takes the helm of the company, the message to the market is clear: Omnicom is serious about AI, serious about commerce, and serious about winning. The platform is ready. The team is ready. The leader is ready.
