When I tell CEOs and MDs I work as a Fractional Commercial Director, I usually get one of two responses:
- “That sounds interesting, but does it actually work?”
- “We need commitment. That means full-time.”
Both are fair concerns. This article sets out what the numbers look like, what founders actually get, and where fractional leadership is and is not the right answer.
Fractional leadership is no longer a fringe arrangement
Research by Tomoko Yokoi and Amy Bonsall, published in Harvard Business Review in July 2024, found more than 110,000 people on LinkedIn describing themselves as fractional leaders in early 2024, up from 2,000 in 2022.
Growth on its own proves nothing. What matters is whether the model delivers for the business paying for it.
Speed to impact
In my experience, a new full-time Commercial Director needs six to twelve months to learn the business and make a strategic difference. A fractional leader arrives with frameworks tested in several businesses, so the work starts in the first week and the first changes land within the first month. They are not learning on your payroll. They are applying what already works.
The real cost comparison
Money is what keeps founders up at night, so here are the numbers. The full-time figures use Glassdoor salary data for September 2026. The fractional figures are my own published fees.
Full-time Commercial Director
- Base salary: £71k to £115k, average £90k
- Bonus and commission: around £24k on average
- Employer National Insurance, pension and benefits: £15k to £30k
- Search fee: 20% to 30% of base, £14k to £35k
- Time to full productivity: six to twelve months
Year one: £125k to £205k
Fractional Commercial Director
- One to two days a week: £2,500 to £4,500 a month
- No recruitment fee, no benefits, no notice-period lock-in
- Frameworks arrive with the person, so the work starts in week one
- Scale up or down as the business needs
Year one: £30k to £54k
That is roughly a quarter of the cost, for the part of the role that actually moves the numbers. See how the fractional role is priced and scoped.
But the numbers do not capture the biggest cost of all: the cost of delay.
What founders get
1. Strategic thinking without operational drag
Full-time executives get pulled into day-to-day operations, meeting after meeting. That is the nature of being in the building. A fractional leader is hired to think, roll up their sleeves and deliver an outcome, so they stay on the questions the founder has no time to ask.
2. Pattern recognition from more than one business
A fractional leader typically works with three or four businesses at once. That means constant exposure to what works, what fails and why. You are not hiring one career’s worth of experience. You are hiring what is being tested right now, in several places at once.
3. Capability, not dependency
A good fractional leader knows the engagement is temporary, so the incentive is to build systems and frameworks the team can run without them. If your business still needs me in the room after the work is done, I have not done the job properly.
4. A different risk profile
If a fractional engagement is not working, you adjust it or end it. Unwinding a senior full-time hire is slower, costlier and far more disruptive.
The three objections I hear most
Will a part-time person be less committed?
Commitment is measured in outcomes, not hours in the office. A fractional leader is judged on what changes in the business, and that tends to sharpen focus rather than dilute it. Put me in a full-time role with the same desired outcome and I would run out of useful work well before the week was over, while you were still paying for all of it.
How can someone help if they are not here every day?
Most founder-led businesses do not need forty hours of strategic commercial thinking a week. They need eight to twelve hours of high-quality strategic work. The rest is execution, which your team should own, using the frameworks the fractional leader builds.
Will they leave just when we need them?
A well-run fractional engagement is designed with its own exit in mind. When the business is ready for a permanent hire, a good fractional leader helps scope the role and recruit the right person. The more common problem with full-time hires runs the other way: they stay long after they have stopped adding value, or leave abruptly and take the knowledge with them.
Where fractional leadership works best
Fractional leadership works best in three situations.
1. At a growth plateau
The business model is proven, but growth has stalled against constraints the founder cannot fix alone. The business needs strategic frameworks to scale but cannot yet justify a six-figure full-time hire. There are only so many hours in a founder’s day. You cannot make more of them, only free some up.
2. During change
A merger, a repositioning or a new service launch. A fractional leader with transformation experience brings tested playbooks that compress a year or more of trial and error into a few months.
3. When the team needs to grow up commercially
The goal is to professionalise commercial operations and build leadership capacity in the people you already have. Knowledge transfer is the point, not a side effect.
What this means for your business
Fractional leadership is not right for every business at every stage.
If you are under £1m and still finding product-market fit, you need to be in the detail yourself. I can still help, but as an occasional sounding board rather than a fractional director.
If you are above £15m with complex operations and a full executive team to build, you probably need a permanent Commercial Director. A fractional leader is best used there to hold the commercial seat while you make the right hire, which takes time.
If you are between £1m and £15m, fractional leadership gives you:
- Senior commercial thinking at around a quarter of the cost of a full-time hire
- Work that starts in week one, not month six
- Frameworks your team keeps after the engagement ends
- The flexibility to scale up, scale down or stop
And perhaps most importantly, it gives founders their time back.
The question you should be asking
The question is not “can we afford fractional leadership?”
It is “what is it costing us not to have senior commercial expertise?”
That cost is real, even if it never appears on a spreadsheet:
- Deals discounted that did not need to be
- Enquiries from the wrong buyers
- A proposition that sounds like everyone else’s
- Months of trial and error that a tested playbook would have shortened
- Good people leaving because there is no clear commercial direction
- A founder trying to be CEO and Commercial Director at once, and edging closer to burnout
How I apply this
I do not create dependency. I build capability. Every engagement starts the same way and follows three phases over the first quarter.
- Weeks one and two: diagnose. A fixed-price Commercial Diagnostic finds the three to five commercial levers that matter most and turns them into a roadmap.
- Weeks three to eight: build. Strategy and frameworks for segmentation, pricing, pipeline and process, with quick wins along the way.
- Weeks nine to twelve: transfer. Train the team and put systems in place that work without me.
At the end of the quarter we review progress against the diagnostic and agree what comes next. By then you have clarity, your team has frameworks, and you typically have ten to fifteen hours a week of your own time back.
