What a fractional marketing director actually does
Most mid-sized B2B businesses don't have a marketing problem. They have a marketing leadership problem.
There's activity. A website that gets updated, a LinkedIn presence, some events, maybe an agency on a monthly retainer. There's often a capable marketing manager or a small team doing their best. What's missing is the layer above all that - someone senior enough to decide what the marketing is for, direct the money accordingly, and tell the board whether it's working.
A fractional marketing director fills that layer. Part-time, senior, embedded.
What it is (and what it isn't)
A fractional marketing director is an experienced marketing director who works inside your business for a fraction of the week - typically one or two days - on an ongoing retainer. Same accountability as an employed director. Same seat at the leadership table. A fraction of the time and a fraction of the cost.
It's worth being clear about what it isn't, because the market is noisy:
It isn't an agency. Agencies execute. They're good at it when someone has told them what to execute and why. A fractional director is usually the person doing the telling - setting strategy, briefing agencies, and holding them to account on your behalf.
It isn't a consultant who leaves a report. Consultancy projects have their place (I sell them). But a fractional engagement is ongoing. You get someone who owns the outcome month after month, not someone who diagnoses the problem and waves goodbye.
It isn't a freelancer. A freelance marketer gives you extra hands. A fractional director gives you direction. If your problem is capacity, hire hands. If your problem is that nobody senior owns marketing, hands make it worse - more activity, same drift.
When it makes sense
The businesses that get the most from this model tend to be £5-50m revenue B2B firms, and they usually recognise themselves in one or more of these:
Marketing is busy but nobody can say what it's achieving. Plenty of output, no line of sight to revenue. The activity predates any strategy, and nobody senior has ever stopped to ask whether it's the right activity.
A marketing manager is doing their best without direction. Common and quietly expensive. A good manager executing against no strategy will work hard on the wrong things. They don't need replacing. They need directing - and usually developing.
Growth has stalled and the reasons aren't obvious. Sales blames leads. Marketing blames the product. The MD suspects both and can't referee. Someone with pattern recognition from thirty years of these arguments can usually locate the actual problem quickly.
The board or your investors want marketing discipline. PE-backed and founder-led businesses hit this at similar points: someone with capital at stake asks for a marketing plan with numbers in it, and there's nobody in the business who has written one before.
You're between hires. A marketing director has left, or you know you'll need one in eighteen months but not yet. Fractional cover keeps the function led in the meantime - and makes the eventual hire far better informed.
When it doesn't make sense: if what you actually need is execution capacity, or the business is too small to use strategic time properly. A fractional director with nobody to direct and no budget to direct spends expensive days doing junior work. There are better ways to spend that money, and a decent fractional director will tell you so in the first conversation.
How it works in practice
The standard shape is a monthly retainer at a fixed number of days - anywhere from a couple of days a month at the advisory end to two days a week fully embedded. The right level depends on the size of your team, the complexity of what you're selling, and how much needs fixing.
Embedded means embedded. In leadership meetings. Directing the marketing team and agencies. Accountable for the plan and answerable for the results. The useful mental model is an employed marketing director who happens to work for you two days a week - not a supplier you brief.
Two practical points worth knowing before you buy:
It's priced by outcome, not by hours. A fractional director is paid for judgement and results across the month, not for clocked time. If you find yourself wanting to count hours, you're buying the wrong product.
Expect a minimum commitment. Three months is typical. Strategy takes a little time to bite, and nobody serious will sell you one month of direction.
The value
The honest answer to "what do I get?" is: decisions.
Marketing in mid-sized businesses rarely fails from lack of effort. It fails from deferred decisions. Which markets to prioritise. What the proposition actually is. Which half of the budget is wasted. Whether the agency is any good. What the manager should do next quarter and why. These pile up when nobody senior owns them, and every one of them leaks money while it waits.
A fractional director exists to make those decisions, with the benefit of having seen most of them before. The compounding effects follow: budget concentrates on fewer, better things; the team gets direction and gets better; the board gets straight answers instead of activity reports; and sales and marketing start pointing the same way.
There's also a value that's harder to put on a slide: an outside view with inside accountability. Someone who isn't managing internal politics, has no empire to build, and whose only currency is being right often enough to keep the retainer.
The economics
This is where the model earns its keep.
A full-time marketing director in the UK costs £80,000-120,000 in base salary for most sectors and regions, and more in London or technical sectors. That's the start of the bill, not the end of it. Add employer National Insurance, pension, bonus, benefits, and a recruitment fee typically running 20-30% of salary, and the true first-year cost of a permanent hire sits comfortably between £120,000-190,000.
And that's the cost if the hire works. A mis-hire at director level - wrong person, wrong time, or a good person the business wasn't ready to use - costs a year and six figures before anyone admits it.
Fractional engagements typically run £2,500-8,000 per month depending on the days involved - £30,000-96,000 a year at the extremes, with most engagements sitting in the middle. No employer NI, no pension, no recruitment fee, no long notice period, and no redundancy exposure. You get director-level judgement from day one, at the commitment level the business can actually use, and you can scale it up, down, or off as the business changes.
For most £5-50m businesses, the comparison isn't really fractional versus full-time. It's fractional versus nobody - because the full-time hire was never affordable, so the leadership gap just sat there, quietly taxing everything marketing touched.
Where to start
If some of this sounds like your business, the usual starting point is a structured look at what you've actually got - strategy, channels, team, budget, competitive position - before committing to anything ongoing. That's what my Marketing Diagnostic is for. Or start with a conversation, which costs nothing and tends to establish quickly whether this model fits.
