The chair is disappearing, and we helped.

Forrester's latest count of marketing leadership in the Fortune 500 has been doing the rounds this week, and you will have seen the numbers by now. Just over a third of those companies still use the CMO title, down from about half a year earlier. Senior marketing presence on the executive team, or reporting directly to the chief executive, has fallen three years running.

Most of the commentary I have read this week falls into one of two camps. Either the numbers are evidence that businesses undervalue marketing, which is a comfortable thing for marketers to conclude, or they are evidence that the role is evolving into something broader and better, which is comfortable for a different reason. Both readings position marketing as the party something is being done to.

I think there is a third reading, and it is less comfortable, because it makes us a participant rather than a bystander.

Start with what the title is being replaced by. Chief Growth Officer. Chief Commercial Officer. Chief Customer Officer. These are not junior roles, and the businesses creating them are not deprioritising the work. Every one of those titles has something the CMO title does not.

It owns a number.

The part we don't want to look at

Here is where I have to implicate myself, because I do fractional and interim marketing leadership, and I think the way our end of the market sells is part of this.

The clue is in the word. Fractional. We named the category after the portion of time being purchased, not after anything the work produces. Every other C-suite title in the business describes a domain of accountability. Ours describes an allocation.

Now, most fractional leaders would object to that characterisation, and they would do it in a particular way. They would say the proposition is not really about the days at all. It is about access to senior expertise a company could not otherwise afford. It is about strategic thinking. It is about stewardship of the function, bringing rigour, mentoring the team, raising the standard of the work.

I have said versions of all of that. And I would gently point out that every one of those phrases is the sort of thing that glazes the eyes of a commercially minded executive. Strategic thinking is not a deliverable. Stewardship is not a number. They describe a quality of attention, which is genuinely valuable and completely unfalsifiable.

So the buyer, quite reasonably, converts the pitch into the only term they can evaluate. However elegantly the role is described, the contract underneath it is days. Two a month, four a month, a day a week. That is what is priced, that is what is negotiated when budgets tighten, and that is what gets reduced.

However a fractional leader defends the role, it resolves to days purchased. That is not a pricing detail. It is the positioning.

And a business that has learned to buy marketing leadership in units of time has learned to think of it as a resource to be optimised, rather than a seat that owns an outcome. Which is precisely what a company does when it removes the title and folds the work under someone who owns a number.

The third defence, and why it is the weakest

There is one more answer a fractional leader will give, and it is usually the first one out of the mouth. Never mind the days. I am there to drive growth. To move revenue.

I wrote last week that marketing is not a revenue function, because revenue is one line on the profit and loss account and in almost every business it already has an owner. Two functions cannot own the same number. Claiming a share of it puts marketing in a credit dispute it will lose, because sales closed the deal and everyone in the room knows it.

The fractional version of that claim is the same mistake in a weaker position.

Consider the room it is being made in. A founder-led business, or one with an established sales director, where somebody has personally carried the revenue number for years and can name the deals they closed. Into that room walks a marketing leader, two days a month, announcing they are here to drive growth.

Nobody says no. What happens instead is quieter. The claim is accepted in principle and then translated, immediately, into the only request a part-time marketing person can actually be held to.

More leads, please. And now the days are being counted against a number the fractional was never in a position to own.

So the pitch that was supposed to demonstrate commercial seriousness produces the least commercial arrangement available: a small allocation of time, measured on lead volume, against a revenue target belonging to somebody else. That is not a seat at the table. That is a supplier with a monthly report.

I am not arguing against fractional or interim work. I do it, I think it serves businesses well, and for many companies it is plainly the right answer. I am arguing against the unit. Days bought is a cost measure, and anything a business understands purely as a cost eventually gets reduced.

Broadening the remit will not fix it

The advice that follows this data is usually to expand: take on retention, take on customer success, take on more of the lifecycle, and the seniority will follow. Forrester's own reading is that this reinvention is an opportunity for marketing leaders to take greater responsibility for commercial outcomes, which I think is right.

But I would put the sequence the other way round. Authority follows evidence, not scope. A leader who cannot yet evidence the responsibility they hold is not strengthened by being handed more of it. They are exposed by it. More surface area, same inability to say in commercial terms whether any of it is working.

Scope is what you are given after you have proved something. It is not the proof.

What actually earns the chair

There is one number in most businesses that nobody currently produces. What it costs to win a customer, counted properly, against what that customer is worth over their life.

Sales cannot produce it, because sales is measured on the top line and has no reason to load its own cost into a ratio. Finance sees the totals but not the mechanics of acquisition, so it can tell you what was spent but not which segment was worth winning. It sits in the gap between the two, and it is the only figure that says whether the growth a business is buying is creating value or quietly consuming it.

It also happens to reward exactly what marketing controls. Sharper targeting lowers what a customer costs. A stronger brand lowers it again, because deals start warm rather than cold. Better retention and expansion raise what they are worth. Every lever in that ratio is a marketing lever, and the ratio itself is written in the language finance already uses.

So the honest reading of Forrester's numbers is not that marketing has been demoted. It is that the seat is being handed to whoever will answer for the commercial outcome, and for the moment that is not us.

The chair is not disappearing. It is being reassigned, and the number that claims it is sitting there unowned.
