As part of the upcoming CMO Lab at POSSIBLE (April 27–29 in Miami Beach), I sat down with Nadine Dietz, who is leading the initiative and has spent years working closely with CMOs across the industry through her work at Virtuosi League, Adweek, and Marketers That Matter.

The conversation quickly moved beyond the event itself and into something more telling.

On paper, the CMO role hasn’t changed. The mandate is still growth, customer, and brand. But in practice, the role is operating in a completely different environment than it was even a few years ago.

That gap between what the role looks like and how it actually operates is where much of the friction is today.

And it’s also where many agencies are falling behind.

The Shift Isn’t Marketing. It’s Enterprise.

One of the biggest changes Nadine pointed to is where CMOs are actually spending their time.

It’s less about managing marketing execution and more about navigating the enterprise.

CMOs today are expected to operate across the C-suite by aligning teams, influencing decisions, and helping define what growth actually means across the organization. That kind of alignment work isn’t always visible, but it’s now central to the role.

A major driver of this is AI.

Not because of the tools themselves, but because AI decisions don’t live in one function. They impact operations, finance, product, and HR, forcing CMOs into conversations that go well beyond marketing.

They’re no longer just running a function. They’re helping shape the system in which the function operates.

Why Good Ideas Aren’t Enough Anymore

This is where the gap between CMOs and agencies starts to show up.

From Nadine’s perspective, the issue isn’t that agencies aren’t capable. It’s that many are still approaching problems in ways that don’t reflect the reality CMOs are operating in.

Ideas alone don’t move things forward the way they used to.

Strategy can look great on paper, but it breaks down when it doesn’t fit into the broader organization, doesn’t align with other priorities, or can’t scale across teams and systems.

In practice, that breakdown shows up in subtle ways.

An agency might bring a strong campaign idea, but executing it requires new data flows, coordination across product and sales, or approvals that take months to navigate. The idea isn’t wrong. It’s just not deployable in that environment.

And that’s often where momentum dies.

CMOs aren’t just asking, “Is this a good idea?”
They’re asking, “Will this actually work here?”

A Model That’s Starting to Break

There’s also a more fundamental shift happening in how work gets done.

The traditional agency model: long timelines, structured campaigns, and clearly defined scopes, is under pressure. The pace of change, combined with the expectation for real-time responsiveness, is forcing companies to rethink how they operate.

That shift is showing up in team structure as well.

More work is being broken into tasks rather than roles. More talent is being brought in on a fractional basis. And more capabilities that once lived outside the organization are being pulled in-house, often supported by AI.

For agencies, this creates a different kind of challenge.

It’s not just about doing the work better. It’s about fitting into a system that is actively being rebuilt.

What the Best CMOs Are Doing Differently

What’s becoming clear is that the CMOs gaining traction aren’t just focused on marketing outcomes.

They’re focused on alignment.

They’re thinking about how decisions are made across the organization, how teams work together, and how to build systems that actually support growth—not just campaigns that aim to drive it.

It’s a more complex job than it was even a few years ago.

And it requires a different kind of partner.

Where Agencies Need to Rethink Their Approach

If there’s one theme that came through clearly, it’s this: agencies need a deeper understanding of the environment in which their clients operate.

That starts with empathy, but not in the abstract.

In practice, it looks like shifting the conversation.

Instead of leading with ideas, the most effective agencies are spending more time diagnosing constraints:

• How do decisions actually get made inside this organization?
• What would prevent this from working?
• Where are the bottlenecks likely to be?

It also means pressure-testing ideas before presenting them.

Not just “here’s what we’d do,” but “here’s how this would realistically get implemented given your current structure.”

Because from the CMO’s perspective, time is limited and the margin for error is small. Every initiative has to fit within a broader set of priorities that agencies don’t always see.

In many cases, the agencies that stand out aren’t the ones with the boldest ideas. They’re the ones whose ideas actually work inside the system.

The Part No One Talks About

Toward the end of the conversation, the focus shifted from strategy to something less discussed.

People.

Teams are being asked to do more with less. Roles are evolving faster than people can adapt. And there’s a constant level of pressure that sits underneath all of it.

In Nadine’s view, the mental health impact across the industry is significant and growing.

And yet, most organizations are still focused on chasing the next opportunity rather than investing in the people who deliver it.

That disconnect matters.

Because in a moment like this, the strength of the team is what determines whether any strategy actually works.

Why Spaces Like the CMO Lab Are Emerging

That shift is also what led to the creation of the CMO Lab at POSSIBLE.

The idea isn’t to add more content to an already crowded conference schedule. It’s to create space for CMOs to step back, compare notes, and work through challenges that don’t yet have clear answers.

Because that’s the reality right now.

There isn’t a clear playbook for navigating AI transformation, organizational alignment, and evolving expectations simultaneously. Most CMOs are figuring it out as they go.

And increasingly, the most valuable insights aren’t coming from the stage. They’re coming from conversations with peers facing the same problems.

What This Means for Agencies

For agencies, the takeaway is straightforward.

The question isn’t whether you’re doing good work.

It’s whether that work fits the world your clients are actually operating in.

Because that world has changed.

And the agencies that recognize that and adjust how they engage, diagnose, and deliver are the ones that will stay relevant.
