Should you hire a marketing manager or an agency?
The decision is not about cost. It is about which of the two things you are missing — capability you keep, or capacity you rent.

Hire a marketing manager when the problem is that nobody owns marketing day to day, and you want the capability to stay inside the company. Use an agency when you know what needs doing and need specialist capacity to do it. The mistake that wastes the most money is doing either one before deciding what marketing is actually responsible for — an unmanaged agency and an unmanaged first hire fail the same way, for the same reason, and it is not their fault.
What each one actually gives you
An agency sells capacity and specialism. They have run the channel a hundred times, they have people who do only that, and they can start in a fortnight. What they cannot do is hold your company's context — they will not know why the last campaign was killed, which customer segment quietly produces the margin, or what your sales team is hearing this month, unless someone inside your company tells them, repeatedly.
A marketing manager sells continuity and ownership. They accumulate exactly that context, they are in the room when things change, and their incentives run with the company rather than with a retainer. What they cannot be is expert at everything, which is what a job description for a first marketing hire almost always asks for.
Framed this way the choice is less about budget than about which shortage is real. If marketing has no owner, an agency does not fix it — it adds a supplier to manage. If marketing has an owner and no hands, a hire is a slow answer to a fast problem.
Hire a marketing manager when
These conditions point in-house:
- Marketing decisions are currently made by the founder, between everything else, and that has become the bottleneck.
- The work is continuous rather than campaign-shaped — a rhythm of content, customer communication and reporting that never really ends.
- Your product or buying cycle is unusual enough that context takes months to build and would be lost every time a supplier changed.
- You expect to keep spending on marketing for years, so capability that stays is worth more than capacity you rent.
- You have enough clarity on the role to write a job description that names outcomes rather than a list of channels.
Use an agency when
These point outside:
- The need is specialist and bounded — a paid channel, a rebrand, a website build — with a clear finish line.
- You need to move now, and a good hire is three months of searching away.
- The channel requires expensive tooling or a team of specialists that one salary cannot cover.
- You are still testing whether a channel works at all, and want to find out without a permanent commitment.
- Someone in-house is already capable of directing them, reading what they produce, and telling whether it is good.
The combination most mid-size companies end up with
In practice this is rarely either-or for long. The arrangement that tends to stabilise is one accountable person inside the company, plus specialist suppliers where depth or tooling justifies it. The internal person owns priorities, the numbers and the relationship; the agencies own execution in their lane.
That shape only works if the internal person is senior enough to direct suppliers, which is where companies often get the sequencing wrong in the other direction — hiring a junior marketer and then asking them to manage three agencies whose people are more experienced than they are. It puts a person who cannot yet tell good work from confident work in charge of judging it.
If you need the direction before you can afford the seniority, that is the gap fractional leadership exists for: someone senior setting priorities and reviewing suppliers, while the junior in-house hire executes and grows into the role.
Before you do either
Write down what marketing is responsible for over the next two quarters, in a form specific enough to be wrong. Name the numbers that would show it working, including at least one you would rather not look at. Decide who reviews those numbers and how often.
Then read your plan back and ask which of the two shortages it exposes. Most of the time the answer is obvious once the question is written down, which is the actual reason this step gets skipped — it forces a decision that ambiguity was comfortably deferring.
Common questions
- Is an agency cheaper than a marketing manager?
- Per month, often yes; per year of accumulated capability, usually not. An agency retainer buys output that stops the day it ends. A salary buys someone who knows more about your market each quarter. Comparing the monthly numbers alone answers the wrong question.
- What should the first marketing hire be?
- Whatever your actual constraint is, which is rarely the generalist the first job description describes. If the constraint is that nobody owns marketing, hire for ownership and judgement. If it is that a specific channel is under-served, hire for that channel and accept it is a narrow role.
- How long does hiring a marketer take?
- Two to four weeks per role is achievable when the role is defined before the search starts. Most hiring drags because the job itself was never pinned down, so candidates are assessed against a target that moves between interviews.
- Can we start with an agency and hire later?
- Yes, and it is a common path. The thing to protect is the knowledge: insist that reporting, audience data, creative assets and account access live in systems you own, so switching later costs a handover rather than a restart.
