Fractional CMO in place but customer growth still flat? What a £2m to £20m business needs next
Updated: Oct 4
If your business turns over between £2m and £20m, you have a fractional CMO or have had one, and new customers still arrive no more predictably than before, the problem is rarely the quality of the advice. A fractional CMO gives you direction for a few days a month. What usually stalls is the work that turns that direction into buyers finding you, trusting you and getting in touch, and that work was never part of the role. This article is for established businesses in that position. If you're a start-up choosing your first marketing hire, or you're looking at fractional work yourself, it isn't written for you.
Why does customer growth stall even with a fractional CMO in place?
Most established businesses bring in a fractional CMO for the right reasons. New customers had become harder to predict, paid advertising was doing more of the work each year, and the founder no longer had time to fix it personally. A senior marketer for part of the week, without the cost of a full-time executive, looked like the sensible answer.
The plan that follows is usually good. It names the right customers, cuts the channels that were not working and sets a budget. Six months later, though, the business often finds itself with a clearer strategy and much the same pipeline, because the pages, the visibility and the steady flow of enquiries the plan depends on still had to be built by someone, and nobody was responsible for building them.
What does a fractional CMO actually do, and what do they leave to others?
A good fractional CMO audits current marketing, writes a plan for the next six to twelve months, decides which channels to keep and meets the team and suppliers regularly to keep them on course. Many also help recruit, because part of the role is building a marketing function that can eventually run without them.
What a fractional CMO doesn't do is the delivery. A few days a month of leadership can't rebuild the pages that lose enquiries, earn visibility in the searches your buyers make or follow up the leads that arrive. If the business already had people who could do that work well, it would rarely have needed outside help in the first place. The result is a better plan sitting on top of the same problem, and a business paying twice, once for direction and again for the work.
What is the delay costing you?
The fee for a fractional CMO is visible every month. The larger cost is the customers the business keeps missing while the plan waits to be delivered, and it rarely shows up on any report.
To put a number on it, take an illustrative business turning over £5m where one good new customer is worth £30,000 in the first year. If six months pass with a sound strategy but no change in who is finding the business, and that delay costs one new customer a quarter, the business has given up £60,000 of first-year revenue while the plan sat on the shelf.
The pressure on budgets makes that harder to absorb. Gartner's 2025 CMO Spend Survey found that marketing budgets have flatlined at 7.7% of company revenue, that 59% of CMOs say they don't have enough budget to carry out their strategy, and that 39% plan to cut back on agency spend. When budgets are that tight, paying for strategy and then paying separately to deliver it is the most expensive way to buy growth.
What does a growth partner do differently?
A growth partner starts where a good fractional CMO would, with the customers the business wants more of, what one is worth and where good prospects are being lost. The difference is that the same people then do the work and answer for the result, so there is no gap between the strategy and the delivery for momentum to fall into.
Fractional CMO | Growth partner | |
What you're buying | Part-time senior marketing direction | Commercial direction plus the work that builds customer demand |
Main output | A strategy, a budget and oversight of others | A dependable route to new customers, built and improved month by month |
Who does the work | Your team and suppliers, paid for separately | The partner, working alongside your team |
Judged on | The quality of the plan and how well others follow it | The customers and revenue the work brings in |
The work begins with the Growth Blueprint, which finds where customer growth is stuck, what it's costing the business and what to fix first. It then moves straight into fixing it, usually starting with the pages and searches closest to revenue, so the business sees changes in who is finding it within months. If you already have a good plan from a fractional CMO, it's a useful starting point, and the Blueprint shows which parts of it will move customers and in what order. We set out this way of working in what a business growth consultant actually does.
Our own results show what happens when the work starts straight away. Sketch Labs, a London office broker with a strong offline reputation, was winning almost no new clients online when we began. Within six months, organic leads rose 433% and revenue rose 400%, as set out in the case study. That came from changing how the right buyers found the business and what they saw when they arrived, which no plan could have done on its own.
This suits established businesses where one extra right-fit customer is worth a meaningful five-figure sum and the team is prepared to change the offer, the website or the sales follow-up when the evidence says so. If you run a large in-house marketing team that already delivers well and simply needs senior leadership, a fractional CMO remains the right hire for you.
How do AI search and buyer research change what you need?
Buyers now research on Google, in AI Overviews, in ChatGPT and Perplexity, on LinkedIn and through people they trust, often long before they speak to anyone. A strategy does nothing to make a business visible or recommended in those places. Clear positioning, useful pages, consistent descriptions of what the business does and visible proof do, and they have to be built, maintained and measured against the customers they bring in.
That is the work a growth partner does every month and a fractional CMO has to hand to someone else. It's also why organic growth has become the more dependable route for businesses that are tired of paying for every new enquiry, a trade-off we look at in paid ads vs organic growth.
Is your current marketing leadership moving customers?
If you have a fractional CMO in place, or had one in the last year, test the arrangement against a few questions.
Has the plan changed who is finding your business, or only how the marketing is organised?
If paid advertising stopped for a month, where would next quarter's new customers come from?
Is the founder still the main source of new business?
Who is responsible for building the pages and visibility the plan depends on, and are they doing it?
When a good prospect chooses a competitor, do you know why?
If several of those answers are uncomfortable, more direction won't fix it. The business needs the route to new customers built, by the people who diagnosed the problem. The pattern behind the third question is one we cover in founder-led sales.
Direction was rarely the missing piece
Most established businesses already know roughly who they want to sell to, and a good fractional CMO will have confirmed it. What they lack is a dependable way for those buyers to find them, trust them and get in touch, and that has to be built by someone who is judged on the customers it brings in. If you're weighing up the timing, when to invest in organic growth sets out the signals worth checking.
If your business still depends too heavily on paid channels, referrals or the founder's network, the Growth Blueprint will show you where customer growth is stuck and what to fix first. If you would rather talk it through, a 15-minute call with James, the founder, will tell you quickly whether Market Jar is the right fit for your business.
