Marketing technology has seen plenty of change over the past few decades. But what is happening right now is different, because two massive shifts are arriving at the same time.

The technology stack marketers rely on is being disrupted by AI and agents, and the behavior of the modern buyer is changing, because of AI and agents, in ways that make the old stack incompatible with what comes next.

The traditional Customer Data Platform (CDP) is not just becoming dated, but is entirely the wrong tool for today’s job.

Picture a customer who wants to book a flight. Within seconds, she deploys three agents: one to research routes and airlines, one to scan her inbox for loyalty offers and compare prices across the web, and a third to make the purchase and negotiate the best deal. What used to be a multi-week journey now happens in milliseconds, across every channel at once, without a human consciously steering it.

This creates three requirements that today's marketing infrastructure was never built to meet.

The first is speed. Agentic buying lifecycles operate in milliseconds. Any system working in batch cycles of days or weeks is invisible to this buyer by the time it responds.
