Fractional Leadership

Marketing Agency, In-House or Fractional: How to Decide

Stefka Team October 19, 2026 7 min read

The question is usually posed as two options and it has three. Build a marketing team in-house, buy an agency, or put senior leadership on part-time and buy execution underneath it. The third is the one missing from almost every version of this comparison published online, and there is a straightforward reason for that.

We pulled the full Google results for marketing agency vs in house on 19 October 2026, twenty positions deep. Fourteen of the nineteen organic results are marketing agencies. The other five are Reddit, LinkedIn, Lemon8, eCommerceFuel and MarketingProfs. Not one result comes from an in-house team, an independent analyst, or anyone selling the third option.

Who is answering this question?

Google's AI Overview holds absolute position 1 and builds its answer from ten domains across twenty-eight citations. Here is what they are.

Two of the ten are careers sites. Indeed's citation comes from /career-advice/career-development/in-house-vs-ad-agency and Bright Network's from /career-path-guides/marketing-pr/. Both are written to help a marketer choose where to work. A company deciding how to resource a function is getting part of its answer from advice written for job applicants — and Google's own related searches for this query include "Marketing agency vs in house salary", which is the same contamination showing up a second way.

And only one of those ten domains ranks on the query it is answering. trinityp3.com supplies the largest share of Google's answer on 734 US organic keywords and 530 monthly US organic visitors, while o8.agency — 5,130 keywords, 3,541 monthly visitors — is cited by neither this answer nor the adjacent one. Ranking and citation are separate systems, and this is the fourth time this year we have been able to measure it on a single page.

The three options, and how each one fails

The failure-mode row is the one to read, because these are not differences in quality. They are three distinct ways the same money disappears.

In-house fails by being too narrow. The first marketing hire is asked to be senior at positioning, paid media, content, lifecycle and design simultaneously. Nobody is. What you get is one strong channel and four weak ones, and no way to tell which is which from inside.

Agencies fail by being too far away. An agency optimises the brief it was given. If the brief is wrong — wrong segment, wrong claim, wrong channel — the agency will execute it well and the result will still be nothing. Google's own AI Overview puts this politely as "communication layers": feedback passing through account managers rather than reaching the person doing the work.

Fractional leadership fails when nobody inside owns the output. Direction that arrives with no implementer becomes a strategy document. This is the same failure we have documented in the audit market, where the most expensive outcome is a thorough report that changes nothing.

The hybrid model, and the option Google forgets

Google's AI answer ends by recommending a hybrid: "an internal marketer or marketing leader owns the core brand voice and strategy, while outsourcing execution-heavy or specialized tasks".

That is sound. It also leaves out the only hard part. It never says who that internal leader is, or how a company too small for a full-time CMO acquires one. For a thirty-person B2B SaaS company, a full-time CMO is a €200,000-plus commitment against a function that may not yet justify it — and the hybrid model collapses without the leader at the centre of it.

That person is what fractional marketing leadership is. When to hire a fractional CMO covers the timing; a fractional team instead covers the case where you need more than one pair of hands at the same time.

What about "outsourced marketing"?

It is the same decision under an older word, and the word is on its way out in one channel and not the other.

outsourced marketing draws 390 Google searches a month at a $43.63 cost per click — serious commercial intent. On AI assistants it draws 192 a month, the largest figure we have measured on any term in two months of weekly tracking, and it is falling steadily: 325 a month a year ago, 192 in September 2026.

That pattern — large, commercial, declining on assistants — matches every other label in this category. We have watched outsourced cmo fall from 9 assistant searches a month to 4, part time cmo from 10 to 4, interim cmo from 7 to 4, and virtual cmo from 5 to 2, while the question phrasing rose. People bring a label to a search box and a question to an assistant. What the outsourced CMO label means covers the term itself; this page covers the decision behind it.

How to actually decide

Three questions, in order.

1. Is the gap hands or judgement? If work is not getting done, you need hands — in-house or an agency. If work is getting done and nobody can say whether it is the right work, you need judgement, and adding hands will make it worse faster.

2. Is the work continuous or campaign-shaped? Continuous, product-specific work with institutional memory belongs inside. Campaign-shaped work with a defined start and end belongs outside, and agencies are genuinely good at it.

3. Who will be answerable in a quarter? Name a person before you sign anything. If the answer is "the account team" or "we'll see", the structure is already wrong, and no amount of supplier quality fixes it. Firm or independent is the same question one level down.

Then check it against the money. What to budget either way sets out what a B2B SaaS company at each stage can reasonably spend, which usually settles the question faster than the arguments do.

Where Stefka fits

We are the third option, and we should say so rather than pretend to be neutral: an independent AI-native studio for B2B SaaS, run from Amsterdam, selling marketing leadership with execution attached. One named person is accountable, and we publish the price — engagements start at €5,000 a month.

We also publish our own measurements, including the ones that do not flatter us: twenty-two ranking US keywords, three monthly organic visitors, and zero genuine AI mentions at the most recent pull. In a market where fourteen of nineteen results are agencies arguing you should hire an agency, that seems like the minimum.
