Rent the CMO, Own the System

There is a version of fractional marketing that I want no part of, and it is unfortunately the dominant one.

It goes like this. A company cannot afford a full time senior marketer, so it buys two days a week of one instead. The fractional CMO turns up, does the work a full time CMO would do at roughly forty per cent of the volume, and the arrangement continues indefinitely because nothing has been built that survives their absence.

That is not a fractional model. That is part time employment with worse job security and a nicer invoice.

It also produces a specific and predictable outcome. Two years in, the company has had a competent senior marketer for a while and has learned nothing. The moment the engagement ends, capability leaves with it, because capability was never the product. Hours were the product.

What you should actually be buying

The useful version of this arrangement is not cheaper senior labour. It is compressed senior judgement, applied to build something the company keeps.

The distinction matters commercially, so let me be specific about it.

A company at the stage where fractional makes sense usually has the same four problems. It does not know precisely who it is for. It has a marketing function that executes but does not direct. It has no reliable way to tell whether marketing is working. And the leadership team has no shared language for discussing any of the above, which is why the marketing conversation in the board meeting goes in circles.

None of those are labour problems. You cannot fix any of them by adding hours. They are all structural, and structures can be built once and then owned.

So the work is: define the position, build the operating rhythm, install the measurement that leadership actually trusts, and develop the person who will run it when I am gone.

That last one is the part that separates the two models, and it is the part most fractional arrangements quietly avoid, because it is the part that ends the engagement.

The build to own model

I structure engagements around what the client keeps, not what I do.

Phase one is diagnosis. Six to eight weeks. What is the actual position, what does the market believe, where is the commercial model leaking, and what is the honest state of the function. This produces a shared and often uncomfortable picture. It is worth doing on its own even if nothing else follows.

Phase two is construction. This is the bulk of it. Positioning, the plan, the operating cadence, the reporting that a CFO will accept, and the hiring or reshaping of the team. I am in the business during this phase in a real way, including the parts that are not strategy. Someone has to write the messaging framework and it may as well be the person who decided on it.

Phase three is handover. Deliberate, scheduled, and started long before it is comfortable. The internal marketing lead runs the meetings. I attend fewer of them. The reporting goes to the board without me in the room.

Phase four, if it happens at all, is advisory. A day a month. Someone to test decisions against. This is where a good relationship should end up, and it should cost a fraction of what phase two cost.

If an engagement is not visibly moving through those phases, something has gone wrong, and usually what has gone wrong is that it became comfortable for both sides.

The honest trade-offs

I would rather set these out than have them discovered.

You get less of me than you would get of a full time hire. That is the deal. It works because a senior marketer's value is concentrated in a relatively small number of decisions, and the rest is execution that other people can do better and cheaper. It does not work if your actual need is high volume delivery. If you need someone to run six campaigns a quarter, hire a marketing manager and an agency. You do not need me and you should not pay for me.

It is disruptive early. Diagnosis surfaces things. Sometimes it surfaces that the product is not differentiated, or that the sales team does not believe the proposition, or that the previous marketing hire was set up to fail. Leadership teams say they want honesty and then discover honesty has a cost. Worth knowing your own appetite for that before starting.

Handover requires someone to hand over to. If there is nobody internal capable of taking it on, and no intention to hire one, the model degrades back into the labour version regardless of how it was sold. I would rather have that conversation in month one.

It is not the cheap option. It is the efficient option. A day rate that looks expensive next to a salary is the wrong comparison, because you are not buying days. You are buying the compression of a two year learning curve into six months, and the avoidance of the mistakes that curve normally contains. Compare it to the cost of the wrong hire, or the cost of eighteen months of activity aimed at the wrong position, and the number reads differently.

Why this model got more attractive, not less

The obvious question in 2026 is whether AI reduces the need for senior marketing help, since the execution layer has compressed so dramatically.

It has done the opposite, for a reason that took me a while to articulate.

What AI removed was the constraint that used to protect companies from their own strategic vagueness. Previously, if your positioning was unclear, you found out slowly, because producing marketing was expensive and you only produced so much of it. Now you can produce an enormous volume of well written, professional looking material that faithfully expresses a position you have not actually decided on. The vagueness scales. It just scales invisibly, until you look at the pipeline eighteen months later.

The scarce resource is no longer the ability to make marketing. It is the judgement about what marketing should say, who it is for, and what you are prepared to give up. That was always the senior job. It is now nearly the whole of the senior job.

Which is a reasonable summary of what a fractional arrangement should be buying you, and a reasonable test of whether yours is.

If the answer to what you have gained from your fractional CMO is a lot of activity, you have bought labour.

If the answer is that the company now knows what it is, and someone internal can run it, you have bought the thing that was actually worth buying.
