People who search “outsourced CMO” are usually thinking about money. The word carries a cost-reduction flavour that “fractional” doesn't. Fair enough. So let's start with the numbers and get to the philosophy later.
What a permanent CMO actually costs
The salary is the number people quote and the smallest part of the picture. A full accounting includes:
- Base salary for a CMO capable of running marketing at a company doing eight to fifteen million
- Employer costs on top: national insurance or payroll taxes, pension, benefits. Commonly 15 to 25% of base
- Bonus, typically 15 to 30% of base at executive level
- Equity, which costs you nothing in cash and a real amount in dilution
- Recruitment fee, usually 20 to 30% of first-year package if you use a search firm
- The vacancy. Four to eight months from decision to first useful day, during which marketing runs on whoever is nearest
- Severance risk. Average CMO tenure is the shortest in the C-suite. Price in a reasonable probability of paying twice.
Add those and the true first-year cost of a permanent CMO is materially higher than the number in the job advert. Then there's the part that doesn't appear in any spreadsheet, which is what happens if the hire is wrong. We've done that arithmetic separately and it's uncomfortable.
What outsourcing actually removes
An outsourced CMO strips out the employer costs, the recruitment fee, the equity, and the severance exposure. You pay a monthly fee against a defined hours band and you can stop with notice measured in weeks.
It also removes the vacancy. That's the part founders undervalue. Getting senior marketing leadership working in three weeks instead of six months is worth more than the fee difference in most businesses, because five months of drift at a company trying to grow 40% is five months you don't get back.
What it doesn't remove is the risk of the wrong person. That risk is smaller, because you can exit quickly, but it's still there and no contract structure removes it.
The honest comparison
Cost-per-hour comparisons flatter the permanent hire and cost-per-outcome comparisons flatter the outsourced one, so both are worth ignoring.
The useful frame is capacity against need. A permanent CMO gives you roughly forty hours a week of senior marketing attention. If your business genuinely needs forty hours of executive-level marketing thinking every week, hire one, and the outsourced route will feel thin.
Most companies at ten million don't need forty hours of it. They need ten to twenty hours of good judgment, and thirty hours of execution that a specialist, a contractor, or a workflow does better and cheaper than a CMO would. Buying the executive to get the execution is where the money actually leaks.
Where the economics stop working
Three situations where outsourcing is the wrong answer, regardless of cost.
You have no one to execute. An outsourced CMO produces a strategy. If nobody runs it, you've bought an expensive document. Either the engagement includes execution capacity or you're hiring in the wrong order.
Your marketing team is already sizeable. Past roughly six or seven marketing people, the internal management load becomes a full-time job. Fractional leadership over a team that size means a manager who's rarely in the building, and the team feels it.
Marketing is your primary competitive moat. If marketing is the thing that wins in your category rather than a support function for sales, you want that capability permanently in-house and personally invested in the outcome.
The catch
Here's the structural risk, and it's the reason this post isn't just a cost comparison.
Outsourcing execution is normal. Every company outsources something. Outsourcing leadership is different, because leadership includes the decisions about what the company is for in the market. Do that without retaining ownership and you end up in a position where the strategy lives in someone else's head, the systems live in someone else's tools, and the relationships live in someone else's network.
Then the contract ends and you discover that what you actually bought was a dependency.
The fix is not to avoid outsourcing. It's to structure for ownership from the first month:
- The positioning document lives in your systems, not theirs, and your team signs off on it
- Attribution and reporting are built in your stack, on your accounts
- Every workflow is documented well enough for a new hire to run cold
- Agency and contractor relationships are contracted to you, not through your CMO
- There's a named point at which hours step down and someone internal steps up
Ask any provider what your marketing function looks like ninety days after they leave. The quality of that answer tells you what kind of arrangement you're actually entering.
Outsourced CMO for a small business
Smaller companies ask this a lot, so worth being direct. The model works below ten million, but the shape changes.
At three to eight million you typically need fewer strategic hours and more hands, which points to a lighter leadership engagement plus contract specialists rather than a full CMO scope. Ten hours a week of direction and a good contractor executing beats twenty hours of executive time with nobody to hand the work to.
Below about three million, or before you have a repeatable sale, the honest answer is usually no. The constraint at that stage is whether the thing sells at all, and that's founder work. Bringing in senior marketing leadership to solve a product-market fit problem is an expensive way to get a well-articulated version of the wrong strategy.
What you should get for the money
Whatever the fee, these should be non-negotiable and written into the agreement.
- A named person, with their hours specified, whose history you have checked
- Direct reporting to the CEO or founder, in writing
- A weekly written report that includes bad news
- One number they are accountable for, agreed with finance
- A documented handover, defined at the start rather than negotiated at the end
- An exclusions list saying what falls outside scope
If a provider resists any of those six, the resistance tells you which part of the arrangement they intend to keep control of. That's worth more information than any case study.
