AI changed the equation on agency value. Are you getting the most out of yours?

Recent Forrester research found that 70% of B2B marketers prioritize value over cost, but only 53% feel they’re getting that value from agencies. That gap is painful, and AI is widening it fast. 

CMOs are increasingly being asked to do more with less, and maximizing value from the agency relationship is more important than ever. It’s forcing both agencies and marketing organizations to re-evaluate what value actually looks like.

The value of agencies has shifted 

For years agencies were built and hired for output: executing builds, campaigns, content and channels. That model has been shifting for a while, but AI officially broke the math. 

Eighty-eight percent of marketers now use AI in their day-to-day work, and 92% of companies plan to increase their investment over the next three years. Production is getting faster and more accessible, which means it’s no longer where real agency value lives. 

Value has moved upstream into how well a marketing ecosystem connects data across channels, learns and adapts in real time, aligns strategy across workstreams and turns insights into actionable decisions. In other words, value lies in orchestration. Without it, AI just helps each piece move faster: more output, not necessarily more impact. In fact, a 2025 IBM survey revealed that fragmented data and workflows were among the top challenges for CMOs. 

But an integrated marketing system only solves half the problem. Value generation also depends on something more foundational: consultation. Brands don’t just need partners who execute what’s already been defined — they need partners who help define what should exist in the first place.

From vendors to ecosystem, from execution to advice

The marketing leaders getting the most out of both AI and agency partnerships are redesigning how their agencies, internal teams and technology fit together, treating each partner as an integrated part of one system built for growth, rather than a vendor delivering a scope of work. They’re evaluating where work is being duplicated, where insights are getting lost, where AI should and should not be leveraged and which partners are adding to the system’s intelligence vs. just adding output.

With this shift, they’re also moving from asking, “Can you make this thing?” to, “Can you tell me something I don’t already know?” 

The agencies that deliver real value in this system aren’t just a cog in the wheel. They’re pressure-testing briefs instead of simply executing against them — and ideally, bringing a point of view before the brief even exists. They bring outside perspectives the client can’t always see from inside. They act less like a team waiting for direction and more like advisors who provide one. They execute great work, yes, but they are also consultants, connectors and system thinkers.

This is where agencies move from being a supporting resource to a critical extension of the marketing team and trusted strategic advisor. 

What a high performance partnership looks like

In the most effective partnerships, agencies move from outsourced execution to force multipliers. 

This shift can show up in many ways. Here are just a few:

1. Shared systems, not segmented reporting: Data isn’t lobbed over the wall via static reports. It’s accessed, interrogated and acted on collectively, in real time. AI accelerates data generation, but the ongoing thinking around that data is where the value lies.

2. Joint planning, not sequential handoffs: Strategy, creative, media and technology are developed in parallel, not in isolation. The work is actively orchestrated and coordinated toward a unified outcome.

3. Continuous learning loops: Every campaign or initiative delivers key learnings that are applied to the next. 

4. Embedded consultation, not reactive service: The agency is proactively surfacing risks, opportunities and directional shifts, acting as an extension of the client’s strategic brain.

5. Success tied to outcomes: Deliverables don’t define success—business impact and decision quality do. 

The bottom line

Agencies are no longer just responsible for delivering work. They are responsible for helping shape what work should exist and why. When a campaign can be generated in seconds, the real advantage isn’t in what gets produced - it’s in the integrated ecosystem, and the intelligence, insights and judgment brought by those that sit inside that system. 

If you’re selecting or onboarding a new agency partner, start by asking to see a point of view on your business early on. Ask them to challenge your assumptions. Tie the scope of work to a business outcome instead of a list of deliverables, enabling flexibility in how the agency reaches those goals. Require partners and internal teams to integrate with each other rather than optimize in siloes.

That’s how marketers and agencies achieve truly valuable partnerships, regardless of how dramatically technology changes the landscape.
