Nick Craig, Head of GTM at Rokt mParticle, joined Marcus Johnson and Principal Analyst Yory Wurmser on EMARKETER's Behind the Numbers podcast to talk about where AI agent are being built in the marketing funnel, why the technology itself stopped being the differentiator, and what settles a campaign's outcome before a single ad ever runs. A few things from the conversation worth unpacking.

AI stopped being the differentiator

AI is getting cheaper and easier to access by the month, and Nick's point was that it now shows up inside every marketing tool, whether that's creative generation, copy assistance, or campaign orchestration. The catch is that those downstream tools are only as smart as whatever slice of data they're trained on. A segment built inside an email platform only knows what that email platform has seen. Yory made the same point from the innovation side: AI has democratized what products get built, but none of that downstream work matters if the upstream data feeding it isn't right.

Which raises the obvious question: what does getting the upstream data right actually require?

Garbage in, garbage out still applies

Nick's answer was blunt. People move in real time, not in scheduled batches, and a lot of marketing data infrastructure still hasn't caught up to that. He pointed to identity resolution and data hygiene as the unglamorous work that decides whether an agent can act on what a customer is doing right now, or only on what they did in last week's export. Get that layer wrong and, in his words, it's garbage in, garbage out no matter how good the model sitting on top of it is. When that foundation is actually in place, the payoff shows up in how audiences get built.

Just tell the agent what you want

Instead of manually building a segment, a marketer can describe the audience in plain language, or go a step further and hand the agent a business goal instead of a segment definition. Nick's example was telling an agent "I'm trying to drive premium subscriptions, help me make money for my business" and letting it propose the segmentation strategy from the full data set. Marcus tied this back to a broader habit shift: the same way search went from five typed words to full paragraphs once AI search took over, marketers are still catching up to how much they can now hand an agent in one request. None of that changes Nick's advice on where to start.

Use case first, agent second

Nick's watched the same mistake happen twice, once with data collection over a decade ago and now with AI: companies reach for the technology first and ask what they can build with it, instead of starting with the outcome they actually want. His fix is to reverse the order. Define the use case, understand the goal, then let AI serve as the enabler, with testing and iteration running the whole time rather than sitting at the end as a final step. Yory's addition was that the upside isn't only speed. It's what that speed frees marketers to do next, including putting the same data to work for teams outside marketing entirely.

Different entry points, same conclusion. When you're evaluating AI tools, the model matters less than what it's trained on and how many teams across the company can actually put it to use.
