In this episode of the Marketing Scientists Podcast, Ian Martins, Managing Director of Zenith, joins us for a no-filter look at the modern agency world. Ian unpacks why the creative/media divide is still costing brands big money, how the traditional agency model is ripe for reinvention, and why the current obsession with AI-driven cost savings is missing the point.

We explore the rise of "Power of One" models, why media teams need a seat at the creative table, and how smart brands are blending brand + performance thinking. Ian also shares practical insights on creative testing, algorithmic buying, and why most media metrics are still chasing the wrong goals.
