How to structure a marketing team that delivers

I was delighted to recently host a marketing breakfast with ten brilliant marketing leaders. The topic was one that sits on most of our desks right now. How do you build a marketing team that delivers when everything around it keeps changing? It is a harder question than it sounds. Budgets move. Channels multiply. AI arrives faster than most teams can absorb it. And the board still wants growth. We set ourselves plenty to work through. How to structure teams today. How to put AI to practical use in teams and workflows. What to keep in-house and what to send out. How to measure team performance and marketing impact. And how teams move past delivery to become a commercial growth function.

These are the points I keep coming back to.

Specialists are still essential

The direction of travel is clear. Teams are more matrixed than they once were. Structure should follow your objectives and the outcomes you are chasing, not an org chart you inherited. But there was a warning under that. The swing toward flexible, blended roles can go too far. Nobody in the room wanted to lose their specialists. The reason is simple. Channels have grown more technical, not less. Real expertise in performance, brand, data and content still wins. A team of capable generalists rarely matches a sharp specialist on the work that matters most. So most leaders favoured a blend. Build a flexible structure around clear goals. Protect a spine of genuine specialists inside it. Then add and remove capacity around that core as the work demands.

It always comes back to people

This point came up over and over. Whatever the tool and whatever the structure, the customer is a person. That sounds obvious. It is also the first thing teams lose as they add technology. The more we optimise to dashboards, the easier it is to forget the human reading the email. Senior leaders treated this as a discipline, not a sentiment. It means keeping real customer contact inside the team. It means qualitative insight sitting alongside the numbers. The brands that hold on to that tend to build the warmer and more durable relationships.

AI belongs in measurement, not output

The AI conversation was not the one you might expect. Hardly anyone was excited about using it to produce more content. The real interest was in measurement. Tracking how content performs. Spotting what works in close to real time. Adjusting spend and message while a campaign is still live. That is where leaders saw the gain. The firmest view of the morning was on data. One CMO put it plainly. Agents only work when you feed them your data, and that data is not yours to give away. So keep your prompts in-house. Keep your agents in-house too. Agentic AI has to stay inside the business. For a senior team this is a governance question as much as a marketing one. Your customer data and your prompts are becoming part of your edge. Hand them to a third party and you hand the edge over with them.

Outsource the disruption

Good creative exists to unsettle things. That is the point of it. Yet brands rarely want their core unsettled, and for good reason. The room had a sensible answer to this. Send the disruptive work out. Let agencies take the creative risks and test the edges, while you hold the centre steady and protect the brand. It is a useful split. Your in-house team guards consistency and meaning. Your partners bring the challenge you cannot always afford to bring yourself.

Agencies still matter, but the brief has changed

Nobody wrote agencies off. Far from it. The value is still there, but the shape of it has moved. What leaders want now is real insight, niche skills and specialist data. They want partners who go further in one area than any in-house team could. What has gone is the single agency that handles everything. That changes how you buy and how you build. The job becomes orchestration. You hold a roster of specialists and pull them together around the goal. The in-house team becomes the conductor, not the whole orchestra.

Should performance report to finance?

One idea took the room by surprise. Should performance marketing sit under the CFO? For most brands that may never be practical. But the point underneath it was serious. Finance and marketing need to work far more closely than they usually do. It takes us back to our last question. How does marketing move past delivery and become a growth function? The answer runs through the numbers. When marketing owns commercial outcomes and speaks the language of finance, it stops being a cost line and starts being an engine.

What I took away

If I had to sum up the morning, it comes down to this. Structure should follow strategy. Specialists still earn their place. AI belongs close to your data and your measurement. Partners should challenge you while you protect the brand. And marketing has to speak the language of growth.

Thank you to everyone who came and spoke so openly. These conversations are exactly why we bring leaders together. If you are working through any of these questions, I am always happy to talk.
