Short CMO Tenure Is a Systems Problem, Not a People Problem

When a CMO leaves after three years, the post-mortem audits the person. Wrong hire, wrong chemistry, not commercial enough, not creative enough, not enough of whatever the last one had too much of. Very rarely does the job itself get audited. It should.

Twenty years, same answer

Spencer Stuart has published CMO tenure data for twenty years. The 2025 figure for S&P 500 companies is 4.1 years, down from 4.3 the year before. On the same study, CEOs average 7.6 years and CFOs 4.7. The pattern has held for two decades, through boom and bust markets, through COVID and the shift to hybrid work, through the digital wave and now the AI one.

If short CMO tenure were a talent problem, two decades of the world's best executive recruiters would have solved it by now. They keep filling the seat, often with exceptional people, and the seat keeps ejecting them. When every incumbent fails the same way, you are looking at a system problem, not a people one.

The job lost three quarters of its remit

The cause is simple on paper. Marketing, as most of the prominent textbooks and thought leaders still define it, is the whole mix. Product, price, place, promotion. Growth is what happens when high quality decisions and executions across those four pull together.

Over decades, three of those four dispersed across the modern org chart, often split across several people or departments. What stayed under the marketing title in many businesses was promotion, plus the budget scrutiny of all four.

So the modern CMO is held accountable for a growth number produced by the whole mix, while holding decision rights over roughly a quarter of it. They can sharpen the campaign but not fix the pricing that undermines it. They can build the brand promise but not the product experience that makes or breaks it. Accountability without control is not just a difficult job, it is an impossible one, and it gets worse when times are tough, growth is hard, and every line of spend is being questioned.

The least standardised role in the C-suite

Even the recruitment industry has diagnosed this, in its own careful language. Spencer Stuart's researchers note that the CMO role has the least standardised scope in the C-suite.

Translate that, given it is describing half of their own client base, and it says no two companies agree on what the job is. Which means most CMOs are hired into expectations that were never clear, and exited for missing them.

Retitling the seat does not grant it decision rights

The realities of 2026 make this more urgent. Forrester's analysis of Fortune 500 marketing leadership found only around 49 per cent of top marketers now hold the CMO title, down from roughly 55 per cent a year earlier. UPS, Etsy, and Walgreens have each eliminated the standalone CMO role, folding the responsibilities into commercial and operating titles.

The fashionable read is that the role is evolving. That would be a genuine positive if it were true, because we do need a way to manage a dispersed marketing mix. Unfortunately the same system problem usually survives the title change. A Chief Growth Officer with no authority over product is the old job with a newer name. A Chief Customer Officer still does not set the price and, bizarrely, often does not oversee customer service either. Retitling the seat does not grant it the decision rights that were missing.

Write down who decides at the seams

There is a better response, and it starts with an admission most boards avoid. The growth outcome you keep hiring one person to deliver is produced horizontally, by decisions scattered across your entire leadership team.

Two things follow from that.

Before the next search brief goes out, write down which decisions the role actually owns, which it influences, and who decides at the seams between marketing, product, finance, and sales. If that document turns out to be impossible to write, you have just found the root of your systems problem, and it was not the last incumbent.

Then accept who already holds the key to the whole. Only one seat in the business spans all four Ps, and it does not sit inside any single vertical department. It is the CEO's. The companies that get this right do not ask their CMO to own growth alone. They make the executive team own the parts of the mix they actually control, with the CEO as the orchestrator, the de facto Chief Brand Officer.

The design, not the people

So before you replace another marketing leader, ask honestly whether anyone has succeeded in this job as it is currently designed. If the answer is no, the people were never the problem. The design was.

This is the same pattern we see in repositioning work. Silos, misalignment, and a story that fragments across the business are almost never caused by the people carrying them. They are caused by a structure that makes the intended outcome impossible to produce. Fix the design and the same people usually deliver.
