James Greaney: Building Trust with AI and Data Strategy

In this edition of The Executive Outlook , we had the privilege of speaking with James Greaney , a data and AI leader whose career spans more than 25 years across clinical trials, marketing, advertising, and corporate transformation. Today, he serves as Chief Data Officer at Clemenger BBDO , known for blending technical depth with creative insight, James has been at the heart of a discipline that has evolved dramatically from the rigid world of medical statistics to the dynamic, fast-moving space of AI-driven business innovation.

What makes his story compelling is not just the breadth of his career but the way his journey mirrors the broader evolution of data itself. He has lived through data’s transformation from something viewed as back-office support into the central nervous system of decision-making, customer experience, and creativity. And through it all, his enthusiasm has never wavered. 

James began with a simple reflection on his early days. “I was good at maths in school. When you’re good at something, you tend to enjoy it, and that enjoyment carries you forward. That’s what happened with me—I kept going deeper, and it eventually led me into medical statistics, where I worked on clinical trials. But I quickly realized that the environment was a little too strict for my personality. It was important, but it didn’t leave much room for imagination.”

That realization nudged him into marketing and advertising, where he found the perfect balance between structure and creativity. “Direct marketing at the time was all about test and learn, running control groups, understanding outcomes. The statistical skills I had developed were directly transferable. It was the same toolkit, but suddenly it had room to breathe, to create, to influence.” 

Over the last two decades, James Greaney has witnessed how advertising has grown more sophisticated as computational power and AI capabilities have expanded. “The things we can do now are extraordinary. The types of models we can build, the speed at which we can operate, the scale of insights we can generate—it’s all so much more advanced. And yet, despite how far we’ve come, it still feels exciting, because there is always another frontier.”

One of his proudest examples comes from his work with Samsung in the Australian market. The challenge was to make sense of the vast amounts of first-party data the company held and combine it with external sources. “Data often sits in silos—different places, different formats. What we did was bring it together into a coherent story. We orchestrated multiple data sources, layered in analytics, and built evidence-based insights that allowed the business to act with confidence. It wasn’t about producing dashboards for the sake of it. It was about making the data work for the business—showing where opportunities existed, where gaps needed closing, and where the return on investment was truly happening.” 

That sense of evidence and clarity extended into one of the most memorable projects of James’s career: the ICC Women’s T20 World Cup in 2020. The objective was bold—fill the Melbourne Cricket Ground for the final and make it the biggest women’s sporting event ever held. James and his team built models to forecast ticket sales for every match leading up to the event. “We could see whether we were pacing ahead or behind expectations. If we were behind, we knew how much to invest, which audiences to target, and through which channels. Smaller matches, like ones involving lesser-known teams, required more effort to bring crowds in. But big-ticket games, like India versus Australia, would sell out on their own.”

The approach wasn’t just tactical; it was cultural. “Everyone involved knew exactly where things stood. There were no Monday morning surprises. If we were off track, the data showed it immediately. That transparency meant we could spend time discussing solutions instead of debating what the numbers were. That’s the power of analytics when done right—it creates trust.” 

James believes this cycle of measuring, learning, and improving is the very heartbeat of modern business. “Optimization is a word we often use. What’s wonderful is that we never actually reach it. There’s always another improvement to make, another process to refine, another opportunity to uncover. That pursuit is what makes the work endlessly engaging.”

But even as he speaks about opportunity, James is candid about the challenges organizations face. “Strategy doesn’t sound glamorous, but it’s essential. Privacy, ethics, governance—these are not optional anymore, they are central. Many companies spend heavily on software or licenses, but without proper frameworks and ownership, the systems don’t deliver. People blame the tools, but really, it’s about whether the foundations are right. Governance and structure may sound old-fashioned, but they’re what allows innovation to thrive.” 

For businesses just starting their data journey, James advises clarity above all else. “You must know what you’re trying to achieve. Identify the metrics that truly matter to the business. Click-through rates might look impressive, but do they really move the needle? Sales, conversions, customer retention—those are the numbers that change outcomes. Once you have that clarity, socialize with it. Put it into dashboards or visualizations that get people talking. Curiosity is contagious. When people start asking questions, you suddenly have momentum, and momentum gets you investment.”

The conversation naturally turned toward AI , and James’s passion for the topic was unmistakable. “AI is one of the great disruptors. For a long time, people thought creativity would be immune to disruption. We now know that’s not true. AI is reshaping processes that have been ingrained for decades. It’s exciting, yes, but it’s also exhausting, because so much needs to be rethought.” 

He gave a simple but striking example: animating a still image for a video. “It sounds straightforward, but suddenly you’re asking questions about the rights of the photographer, the contracts with the talent, and the ethics of repurposing creative assets. These are conversations we never had to have before. That’s disruption in its purest sense.” 

To James, the tools themselves are not the story. The story is how they change our workflows and our thinking. His firm has even embarked on qualifying for international AI security certifications to ensure they are using these technologies ethically and safely. “Adoption is happening in our personal lives at an incredible pace. But in our professional lives, we need to push ourselves to use these tools just as fully. That’s where the opportunities lie.”

What excites him most is the cultural shift that comes when data becomes accessible. “People often say they’re not good with numbers. But everyone understands when their football team wins because it scored more goals. Data is more natural than people realize. When you surface it in ways they can engage with, curiosity takes over. And from curiosity comes action, alignment, and progress.” 

Looking back, James remains energized by what data makes possible. “It’s always about impact. Whether you’re working with a global brand, a sporting event, or a new business, the question is the same: how do we turn information into action? That’s where the real magic lies. That’s where innovation begins.” 

James Greaney’s journey shows us that data is not static. It is alive, adaptive, and constantly evolving. For him, what began with a love of mathematics has grown into a career dedicated to transforming information into trust, creativity, and growth. His story is a reminder that the most powerful thing data can do is not just inform us—it can unite us in pursuit of something bigger.
