What is a fractional CMO?

A fractional CMO is a chief marketing officer who holds the seat at a company for one to three days a week, on an ongoing basis, owning positioning, channel strategy, the marketing budget and the pipeline number, and directing the agencies and team that execute. In the UK the day rate is £700 to £1,300 in 2026, and two days a week is the most common shape.

Also called

Part-time marketing director, Virtual CMO, Portfolio CMO and Outsourced marketing leader, when an agency is selling it. The job is the same under each name; the words differ by market and by who is selling it. What a fractional executive is covers the pattern across every seat.

What the title means in practice

They decide, the agency executesA fractional CMO does not make the content or run the ads. They decide what the company says, to whom, in which channel and with what budget, then hold the agency, the freelancers or the junior team to it.

Positioning first, traffic secondThe usual first quarter is spent on the message rather than the media, because the traffic problem is most often a clarity problem underneath. A company that cannot be explained in a sentence is not fixed by more spend.

The pipeline number is theirs, with salesMarketing that reports on impressions is reporting on itself. A fractional CMO carries a pipeline or revenue contribution agreed with the sales lead, and the budget is judged against it.

Startups and scale-ups are the typical clientSeries A and B companies with a stalled growth curve, consumer brands with product-market fit and no explanation for it, and B2B businesses building a pipeline function for the first time.

What a fractional CMO is not

Not a marketing agency. Executes a channel and is paid to keep executing it, which is a poor place to ask whether the channel is right. Fractional CMO or a marketing agency.
Not a marketing director. The same seat held five days a week on the payroll, which is the right answer once there is a team to lead. Fractional CMO or a marketing director.
Not a head of growth. Runs experiments and acquisition channels inside a strategy; the fractional CMO sets the strategy. Fractional CMO or a head of growth.

What it costs

A fractional CMO charges £700 to £1,300 a day in the UK in 2026. Higher end for category creation, rebrands and full funnel rebuilds. At two days a week that is £5,367 to £9,967 a month, before VAT and with no employer costs on top, because the executive is not an employee. The full arithmetic, at every day count and against a full-time hire, is on the fractional CMO cost page.

Where the word comes from

Marketing followed finance into the fractional model once founders noticed that agencies execute channels but nobody above them decides which channels deserve the money. The seat grew fastest in B2B software, where the pipeline number made its value easy to measure.

Common questions

What does fractional CMO mean?

A chief marketing officer who holds the seat for a fraction of the week, usually one to three days, on an ongoing basis. They own strategy, positioning, budget and the pipeline number, and direct the agency or team that does the execution.

What is the difference between a fractional CMO and a marketing agency?

An agency executes: content, ads, design, a channel. A fractional CMO decides which of those deserve money and holds the agency to a number. Most companies that hire a fractional CMO keep their agency and finally get value from it.

What does a fractional CMO do for a startup?

Fixes positioning first, then sets the channel plan and budget, agrees a pipeline number with sales, and hires or manages the people who execute. For a Series A or B company the engagement usually starts at two days a week.

Who should hire a fractional CMO?

A company with an agency and nobody above it deciding which channels deserve money, a company spending on ads without attribution, a Series A or B business whose growth curve has flattened, or one with a talented junior marketer and no senior marketer to learn from. Below about ten people the founder is usually still the right marketer.

How much does a fractional CMO cost?

£700 to £1,300 a day in the UK in 2026, most often at one to two days a week. The higher end is for category creation, rebrands and full funnel rebuilds. The monthly and annual arithmetic is on the cost page for the seat.
