The choice gets framed as a budget question. It is not. All three models are affordable at some scale and all three fail expensively when used for the wrong problem.
The useful question is narrower: what are you actually missing?
- Missing hands — you know what to do, nobody has time to do it
- Missing direction — you have capable people producing work nobody has prioritised
- Missing both, which is the most common and least often admitted
Each model answers exactly one of those well.
The agency
What it is good at. Execution capacity across multiple channels, quickly. Specialist skills you cannot justify hiring individually. Established process. Somebody else's problem when a person leaves.
Where it breaks. The senior person in the pitch is not the person doing the work. That is not a scandal — it is the business model. Agency economics require senior time to be spread across pitching and oversight, with delivery going to less experienced staff. Your account gets senior attention for roughly the first two months.
The deeper limitation is structural: an agency cannot tell you to spend less. A recommendation to cut a retainer is a recommendation to reduce their own revenue. Most agencies are honest and still cannot escape this. It shows up as scope that grows, tactics that get defended rather than killed, and reporting that emphasises activity over outcome.
Choose it when you have a clear brief and need it executed. If you can write down what you want and what success looks like, an agency will deliver that efficiently.
Do not choose it when the question is what the brief should be. You will get a strategy deck that leads to a retainer, because that is the only strategy the model can produce.
The in-house hire
What it is good at. Context. Someone who sits in your company learns your customers, your product, and your constraints in a way no external party ever will. Full-time availability. Institutional knowledge that stays.
Where it breaks. The seniority-to-cost curve is brutal at the middle of the market.
A capable marketing manager is affordable and, by definition, does not set strategy — that is a level above the role. A marketing director sets strategy and costs more than the problem is worth at many company sizes. Hiring the manager and expecting director-level judgement is the most common expensive mistake in mid-market marketing.
Then there is the single-point-of-failure problem. One person cannot be strong at positioning, paid acquisition, technical SEO, lifecycle, analytics, and brand. Whatever they are weak at silently becomes your weakness, and you often do not find out for a year.
Choose it when marketing is core to the business, the work is continuous, the role is clearly defined, and you can afford the level that actually solves your problem.
Do not choose it when you are hiring to figure out what the role should be. You will define the role around whoever you hired, and then you are stuck with their shape.
The fractional CMO
What it is. Senior marketing leadership, part-time, with ownership. Positioning, budget allocation, supplier selection, hiring, board reporting. They set direction and hold the standard. They do not produce the work.
What it is good at. Buying judgement without buying forty hours a week of it. Most companies do not need a full-time strategist — they need a small number of decisions made well and then defended over time. It also gives you a genuinely external view: someone with no internal politics, whose recommendation might be spend less.
Where it breaks. They are not available on Tuesday afternoon when something urgent happens. If your organisation needs constant availability, a part-time senior person is a bottleneck.
And a fractional CMO without executors is useless. They will produce excellent decisions and nothing will happen. This model requires that someone can do the work — an internal team, an agency, freelancers.
Choose it when you have execution capacity but no direction, when founder-led marketing has hit its ceiling, or when you are preparing for a raise, an exit, or a new market and need the story to hold up.
Do not choose it when you need hands. That is a different purchase.
Reading it against your actual situation
| Your situation | The likely answer |
|---|---|
| Clear brief, no capacity | Agency, or freelancers |
| Capable team, no direction | Fractional leadership |
| Marketing core to business, defined role, budget | In-house hire |
| Founder doing marketing, hitting the ceiling | Fractional leadership first, then hire |
| Agency work inconsistent, nobody holding the standard | Fractional leadership over the agency |
| Preparing for a raise or exit | Fractional leadership |
| One channel matters, nobody owns it | Specialist or channel manager |
The row most often misread is the fifth. Companies unhappy with an agency usually switch agencies. That fixes nothing if the actual gap is that nobody internal is capable of judging the output. A new agency produces work of unknown quality, judged by the same people who could not judge the last one.
The sequence that usually works
For most companies between roughly one and twenty million in revenue, the healthiest path is not a single choice:
- Fractional leadership sets direction and builds the measurement layer, so decisions can be evaluated. Three to six months.
- Agencies or freelancers execute against briefs with defined standards and stated kill criteria.
- Hire in-house once the role is proven — you now know exactly what shape of person you need, because you have watched the work happen.
- Fractional leadership steps back to advisory, or out entirely.
The value of that order is that the expensive, hard-to-reverse decision — the permanent hire — happens last, informed by evidence rather than by a job description written before anyone knew what the job was.
The questions worth asking any of them
Whichever model you choose, these separate the useful from the plausible:
- "What would make you tell me to stop spending?" Anyone who cannot answer has no kill criteria, and will defend whatever they recommend indefinitely.
- "Who is doing the work, and will I meet them before I sign?" For agencies, this is the pitch-versus-delivery question stated plainly.
- "What happens when you leave?" If the answer does not include documentation and handover, you are buying a dependency.
- "What is the first thing you would check?" Anyone who starts with tactics before measurement is guessing. Anyone who starts with a strategy deck is selling one.
- "What have you been wrong about?" A specific answer indicates someone who tracks outcomes. A deflection indicates someone who does not.
What I would say against my own model
I sell fractional leadership, so read this section with that in mind.
Fractional leadership is genuinely the wrong choice if:
- You need work produced, not decided
- Your team needs daily supervision
- The strategy is settled and the gap is purely capacity
- The business is small enough that the founder's instinct is still better than any framework
That last one is real. Below a certain size, a founder who talks to customers weekly makes better marketing decisions than most consultants. Bringing in senior leadership too early replaces good instinct with mediocre process. The signal that you have outgrown it is when you can no longer personally hold all the channels in your head — not when revenue crosses some number.
If you want to talk it through, the four engagement levels are set out here, including the ones where the honest answer is that you need less than you thought. Or send me the situation and I will tell you which of the three models fits — including when it is not me.
