The CMO’s Job Has Changed. Most Job Descriptions Haven’t Caught Up.
A shift is emerging across boardrooms that has little to do with private equity specifically, though PE ownership makes it sharper and faster. Boards no longer want a CMO who can only talk about brand, campaigns and demand generation. They want a commercial leader who happens to sit in the marketing seat.
Five years ago, a strong CMO was judged on brand clarity, campaign performance, and demand-generation volume. Those things still matter. They are no longer what determines whether a CMO keeps their seat. What determines it now is whether they can sit in the same room as sales and product and argue, with evidence, about where growth is actually being constrained, and whether product, marketing and sales move together behind the answer. It was whether marketing was operating as part of a synchronised commercial system with sales and product, or as a function running its own agenda alongside them."
That is a different job from the one most marketing careers were built to produce.
What changed
Marketing execution has become cheaper and faster. AI has seen to that. Campaigns, content and creative that once required a team now require a brief and a review cycle. What hasn’t got cheaper, and what AI cannot do, is judgement, knowing which growth lever actually moves revenue, and having the credibility to make product, sales and finance move together behind it.
When execution gets cheap, judgment becomes the entire job.
A CMO who can only direct execution is now competing with a tool. A CMO who can diagnose where growth is actually stuck and align three functions behind fixing it is doing something a tool still cannot.
Where this shows up first, and where it’s spreading
PE-backed businesses. This is where it bites fastest, because the tolerance for ambiguity is lowest and the reporting cycle is shortest. A CMO who cannot translate a campaign into a pipeline number, or a positioning shift into a forecast assumption, becomes very visible very quickly to an operating partner used to reading numbers, not decks.
Scale-ups preparing to raise. Investors increasingly diligence the marketing function the way they diligence sales - as a commercial system, not a creative one. A CMO who can only present brand work struggles in that conversation.
Founder-led businesses professionalising ahead of an exit. The marketing function that worked when the founder made every commercial call directly rarely survives the transition to a business that needs to run without them. The CMO who can build that system, not just the campaigns inside it, becomes the one who stays.
Public companies under activist pressure. Boards increasingly want marketing spend justified in the same terms as any other capital allocation decision — which pipeline, which revenue, which return.
The common thread isn’t ownership structure. It’s accountability moving closer to revenue, and marketing leadership being expected to move with it.
What “commercial fluency” actually means
Not a marketer who has picked up some finance vocabulary. A leader who treats messaging, pricing and positioning as commercial levers to be tested against pipeline and conversion data, not creative territory to be defended on instinct. Someone who can sit with sales and product and diagnose, specifically, where the handoff between the three functions is costing the business growth and who has the standing to fix it, not just describe it.
That is a genuinely different skill set from the one most marketing careers are built to produce. It is also, increasingly, the one boards are hiring for, whether or not the job description has caught up yet.
Why hiring for marketing skill alone doesn’t fix it
The instinct, when a CMO isn’t landing with the board, is often to look for a stronger marketer. Better campaigns, sharper brand instincts, more creative firepower. This rarely solves the actual problem because the gap was never a creative quality. It was whether marketing was operating as part of a synchronised commercial system with sales and product, or as a function running its own agenda alongside them.
A brilliant marketer dropped into that same disconnected structure will hit the same ceiling the last one did. The fix isn’t a better marketer. It’s a marketing leader who treats synchronisation with sales and product as the job, not a side effect of doing the job well.
The question worth asking before the next CMO hire
Before writing the next CMO job description, it’s worth asking a sharper question than “what marketing experience do we need”:
Can this person walk into a room with sales and product and change what the business does next, not just what it says?
If the honest answer is uncertain, the job description is still describing 2021. The role has already moved on.
