Agencies vs. Fractional vs. In-House
An honest comparison from someone who's been on all three sides of the marketing relationship.
I’ve sat in all three chairs. I’ve been the agency account manager presenting to clients. I’ve been the in-house marketing lead reporting to a CEO. And now I’m the fractional marketing director working across five businesses at once.
Each model taught me something different. And each one has a version of the truth that the other two don’t want to admit.
The agency model: reach without depth
Agencies are brilliant at scale. They have specialists — a designer, a copywriter, a media buyer, a strategist, an SEO person — and they can spin up campaigns quickly because they’ve done similar work dozens of times before. If you need a brand launch, a product campaign, or a burst of creative output, a good agency can deliver things a solo operator or small in-house team simply can’t match.
The problem is structural. Agencies make money by servicing many clients with the same team. Your account manager is juggling eight to twelve accounts. The strategist who presented in the pitch meeting isn’t the person doing the day-to-day work. And the agency’s incentive is to keep you on retainer, which doesn’t always align with what your business actually needs.
I saw this from the inside. The best agency people genuinely care about client outcomes. But the business model creates friction. You’re paying for overhead — the office, the project managers, the new business team — and that overhead means either higher fees or thinner attention on your account. Usually both.
Agencies work best when you have a clear brief, a defined project, and enough budget to justify their attention. They struggle when you need someone to think deeply about your specific business over months or years.
The in-house model: depth without perspective
Having a marketing person (or team) on staff solves the depth problem. They know your product, your customers, your internal politics. They’re in the meetings, they hear the hallway conversations, they understand why the sales team is frustrated or why that product feature keeps getting delayed.
When I was in-house at Navico and then through the Garmin acquisition, I had context that no external partner could match. I knew which dealers were difficult, which markets were growing, which internal stakeholders needed managing. That context made the marketing sharper.
But in-house has its own blindness. You lose perspective. When you’re inside a business every day, you start to accept its assumptions. The way things have always been done becomes invisible. You stop questioning the positioning because you helped write it. You stop pushing back on the CEO’s pet project because you sit three desks away.
There’s also the cost question. A competent marketing manager in New Zealand costs $80,000 to $120,000 a year, plus leave, plus equipment, plus management time. A marketing director is more. For an SMB doing $2 to $10 million in revenue, that’s a significant line item — and you’re getting one person’s skill set. If they’re great at strategy but average at execution, or great at digital but weak on brand, you’ve got a gap you can’t easily fill.
The fractional model: flexibility with trade-offs
The fractional model — which is what I do now — sits in the middle. You get senior strategic thinking without the full-time cost. You get someone embedded enough to understand your business but external enough to keep perspective. And because a fractional director works across multiple businesses, they bring pattern recognition that a single in-house role can’t develop.
I won’t pretend it’s perfect. The obvious limitation is time. I’m not in your office five days a week. I’m not in every meeting. If something blows up on a Tuesday afternoon and I’m deep in another client’s work, there’s a delay. For businesses that need daily hands-on marketing execution, a fractional director isn’t the right fit.
There’s also a trust gap that takes time to close. When you hire someone full-time, they’re yours. A fractional relationship requires you to trust that someone working fifteen or twenty hours a month on your business can still hold the full picture. Some business owners never get comfortable with that, and I understand why.
So which one should you choose?
It depends on where you are.
Choose an agency if you have a specific project with a clear brief and timeline — a rebrand, a product launch, a campaign — and you need specialist execution you can’t do internally. Just make sure you own the strategy. Don’t outsource the thinking about your own business.
Choose in-house if marketing is core to your daily operations and you need someone embedded full-time. This makes sense for businesses where the marketing function touches sales, product, and customer success every single day. But hire for strategic thinking, not just execution. You can outsource execution. You can’t outsource judgment.
Choose fractional if you need senior marketing leadership but can’t justify (or don’t want) a full-time hire. This works well for SMBs in the $1 million to $15 million range who’ve outgrown doing marketing by committee but aren’t ready to build a marketing department.
The honest truth
Most businesses I work with have tried at least two of these models before landing on the third. The agency relationship that felt expensive and impersonal. The in-house hire who was great at posting on social media but couldn’t build a strategy. The fractional engagement that worked until they needed more hours than the model allows.
None of these models is inherently better. They’re tools, and like any tool, they work when matched to the job. The mistake is choosing based on what feels familiar rather than what your business actually needs right now.
If I could give one piece of advice, it would be this: before you decide on the model, get clear on what you’re actually asking marketing to do. If you can’t articulate the job, no model — agency, in-house, or fractional — is going to save you.
