Retail Media Is Eating the Agency Model Alive

Agencies are now recruiting Amazon and Walmart commerce specialists the way they once chased programmatic talent a decade ago — urgently, expensively, and slightly behind the curve. That alone signals a structural shift, not a passing hire cycle.

Layer in the exit of The Trade Desk's CRO Anders Mortensen after just seven months, and the picture gets sharper. The Trade Desk built its reputation on open-web programmatic. Retail media — walled, first-party, purchase-signal-heavy — is a different game. Leadership churn at that level, that fast, suggests the company is still figuring out where it sits in a world where Walmart and Amazon are increasingly their own ad platforms with their own buy-side tools.

For brands, this creates a genuine problem. Your agency may not have the commerce media depth it's billing for yet. The specialists being hired now are being trained on the job, on your budget.

The smarter move: treat retail media as a distinct discipline with its own measurement logic, separate from awareness-layer programmatic. Demand media-mix clarity from your agency — which spend is reaching new customers versus closing existing ones? That distinction is where retail media actually earns its budget allocation.

The gold rush is real. The expertise is still catching up.
