What It Takes to Be a CMO at an Agency

The agency CMO role is one of the most misunderstood positions in marketing leadership. It sits at the intersection of client service, commercial pressure, and internal culture, and it demands a different skill set than the corporate CMO path most career frameworks are built around.

If you are considering the move into agency marketing leadership, or you have just landed the role and are trying to get your bearings, this primer covers what the job actually involves, where most people underestimate it, and what separates the CMOs who make a lasting impact from those who burn out quietly in the first eighteen months.

What Makes the Agency CMO Role Different

Most CMO primers are written with the corporate brand in mind. A consumer goods company, a SaaS business, a retailer. The frameworks make sense in those contexts because the marketing function is pointed outward at a defined customer base, and the internal audience is largely a supporting cast.

The agency CMO has a more complicated brief. You are marketing to prospective clients, yes. But you are also marketing to prospective talent, existing talent, the trade press, award juries, and in many cases, to the agency’s own leadership team, who may have never thought seriously about what their business stands for or how it is perceived externally.

I spent years inside agencies before running one, and the thing that consistently surprised me was how little internal alignment existed around what the agency actually was. Every pitch deck had a positioning statement. Almost none of them reflected how the business actually behaved or what it was genuinely good at. The agency CMO’s first real job is to close that gap, because until you do, every piece of external marketing is built on a foundation that does not hold.

The Commercial Dimension Most CMOs Underestimate

Agency marketing is not a cost centre with a brand brief. It is a revenue function, and the CMO needs to understand that from day one.

When I was running an agency that had been losing money for a sustained period, the turnaround was not driven by a rebrand or a new thought leadership programme. It was driven by cutting what was not working, restructuring delivery margins, repricing services, and bringing in new business through a combination of better positioning and harder commercial discipline. Marketing played a role in that, but only because it was tied directly to commercial outcomes. The CMOs who struggle in agency environments are often the ones who think in campaigns rather than in pipelines.

In a well-run agency, the CMO should have a clear view of the new business pipeline, the conversion rate from pitch to win, the average deal size, and the sectors or service lines where growth is actually happening. If you do not have access to that data, or if the leadership team does not think you need it, that is a structural problem worth addressing early.

BCG’s work on strategic positioning under commercial pressure is a useful frame here. The principle that a business needs a coherent strategic identity before it can grow sustainably applies directly to agencies, which often try to be everything to everyone until someone forces the question.

Building Internal Credibility Before External Positioning

One of the earliest lessons I absorbed in agency life came from a moment that had nothing to do with strategy. I was at Cybercom in my first week when the founder had to leave mid-brainstorm for a client meeting. He handed me the whiteboard pen on his way out the door. I remember the internal reaction clearly: this is going to be difficult. But I picked up the pen and ran the session. That moment mattered more than any credentials I brought with me, because it demonstrated something the team could see in real time.

Agency CMOs who come in with a strong external reputation but fail to establish credibility with the people doing the work tend to find their initiatives quietly ignored. The creative teams, the strategists, the account directors, they are the ones who generate the case studies, the thought leadership, the award entries, the genuine proof points that make agency marketing worth anything. If they do not believe in what you are building, you are producing theatre.

The practical implication is that the first few months in an agency CMO role should involve more listening than broadcasting. Sit in on pitches. Read the case studies that already exist. Talk to the people who have been there for five or more years and understand what the agency has actually delivered at its best. The external positioning should emerge from that, not precede it.

Defining a Point of View That Is Actually Defensible

Most agencies have a positioning problem disguised as a messaging problem. They think they need better copy when what they actually need is a clearer answer to the question: what do we believe that our competitors would not say?

This is harder than it sounds. Agency leadership teams are often reluctant to take positions that might narrow the perceived market. If you say you specialise in B2B technology brands, does that mean you cannot pitch a retail account? If you say you are a performance-first agency, does that rule out brand work? These are real commercial concerns, and the CMO has to handle them without letting the fear of exclusion produce positioning so vague it excludes nothing and says nothing.

The agencies I have seen build genuine market presence over time all had one thing in common: a specific, repeatable point of view that showed up consistently across their content, their pitches, their hires, and their client selection. It was not always a narrow specialism, but it was always something you could feel. A way of thinking about problems. A set of standards they held themselves to. A type of work they were visibly proud of.

Content that serves a real point of view rather than filling a publishing calendar is a different animal entirely. Copyblogger’s piece on fast food content captures the distinction well: volume without substance is not a content strategy, it is noise production.

Managing Upward in a Founder-Led or Partnership Structure

Many agencies are founder-led or run by a small group of senior partners who have been in the business since its early days. This creates a specific dynamic for the CMO that corporate leadership roles do not always prepare you for.

Founders often have strong views about what the agency is and how it should be presented, views formed over years of client relationships and personal identity investment. Those views are not always wrong, but they are not always right either, and the CMO’s job is to bring external perspective and commercial rigour to positioning decisions without triggering defensiveness or losing the room.

Partnership structures add another layer. When four or five senior people all have equity and opinions, achieving consensus on anything as subjective as brand positioning requires a level of political intelligence that does not appear in most job descriptions. The CMOs who handle this well tend to be the ones who lead with data and client evidence rather than personal conviction. It is much harder to argue with what prospects actually say about you than with what a CMO thinks you should say about yourself.

Transparency about process matters here too. Buffer’s approach to operational transparency is an interesting case study in how a business can build trust by being open about how it works, not just what it produces. The same principle applies internally. When the CMO can show their working, the logic behind positioning decisions lands differently than when it arrives as a finished recommendation.

The Talent Marketing Dimension

Agency CMOs who focus exclusively on client acquisition are missing half the brief. The war for talent in agencies is real, persistent, and directly connected to commercial performance. If you cannot attract and retain strong people, delivery suffers, client relationships suffer, and growth stalls regardless of how good your new business pipeline looks.

Employer brand is not a separate workstream from agency brand. They are the same thing, expressed to different audiences. The case studies you publish, the events you run, the positions you take publicly on industry issues, all of it is read by prospective hires as much as by prospective clients. When I was growing a team from around twenty people to over a hundred, the quality of the external brand directly affected the quality of inbound applications. It was not the only factor, but it was not a marginal one either.

The CMO who builds a content and communications programme that serves both audiences simultaneously is doing the job at full scope. The one who treats talent marketing as an HR responsibility and client marketing as their own is leaving significant value on the table.

Awards, PR, and the Proof Point Problem

Awards matter in agencies. Not because trophies on a shelf win pitches, but because the process of entering awards forces rigour around articulating what you actually achieved for a client, not just what you did. Having judged the Effie Awards, I can say with confidence that the gap between agencies who enter with genuine effectiveness evidence and those who dress up activity as outcome is immediately visible. Juries are not fooled by production values and confident language.

The CMO’s role in the awards process is not just administrative. It is about building a culture of effectiveness documentation throughout the year, so that when award season arrives, there is actually something worth entering. That means working with account teams to capture results in real time, not reconstructing them three months later from memory and optimism.

PR follows a similar logic. Trade press coverage that is built on genuine proof points, distinctive thinking, or real client results has a longer half-life than coverage built on press releases about new hires or office moves. The CMO who builds relationships with trade journalists based on consistent, substantive contributions will find those relationships pay dividends over time in ways that a reactive press office approach simply cannot match.

Measurement That Actually Means Something

Agency marketing is notoriously difficult to measure with precision, and the CMO who pretends otherwise will eventually lose credibility with a leadership team that is watching the numbers. The honest approach is to define a small number of metrics that are genuinely connected to commercial outcomes and track them consistently, rather than producing dashboards full of activity metrics that look busy but do not tell you anything useful.

The metrics worth tracking in most agency contexts include: new business enquiry volume and quality, pitch win rate, average deal size, time to first pitch from first contact, and brand awareness among target client segments where that is measurable. Content and social metrics are secondary, useful for understanding what resonates, but not the primary measure of whether agency marketing is working.

BCG’s research on operational resilience makes a point that translates directly: businesses that build measurement systems around lagging indicators struggle to make timely adjustments. The same is true for agency marketing functions. If the only number you are watching is revenue, you will always be reacting too late.

The First Ninety Days: Where to Focus

If I were stepping into an agency CMO role today, the first ninety days would be structured around three priorities, in this order.

First, understand what the business is actually good at and what its best clients say about it. Not the positioning document. Not the pitch deck. What clients actually say when you ask them why they stayed, or why they came back, or what they would miss if the agency disappeared. That is the raw material for everything else.

Second, map the commercial landscape. Where is new business coming from? What is the win rate? Which sectors are growing and which are not? What does the leadership team believe about where growth will come from in the next two years? The CMO who does not have a clear picture of this by day thirty is already behind.

Third, identify the two or three internal allies who will make or break your ability to execute. In most agencies, this means at least one senior creative or strategy leader and at least one person in account leadership. Without those relationships, the CMO is an island with a content calendar.

The tactical work, the website, the content programme, the award entries, can all wait. The strategic foundations cannot, because everything built without them will need to be rebuilt later at greater cost.
