In-House, Agency, or Fractional: How Mid-Market Companies Should Resource Marketing

You are the CEO of a mid-market firm, and marketing has always been a bit of a sore spot.

You have tried to understand modern marketing well enough to make good decisions about how to resource it. But the function has settled into a familiar shape. Someone maintains the company page on social media. Blog posts go up. A newsletter goes out when there is time. Sales asks for a one-pager and gets one.

None of that is bad. It just does not drive growth.

Meanwhile, your competitive landscape keeps getting more crowded. New entrants. Boutique players carving out the exact niche you thought you owned. International firms looking to take share in the US. The clock is running, and the cost of getting marketing wrong keeps climbing.

So what are the actual choices? There are three, and each one carries a real cost and a real set of tradeoffs. Here is how I see them after more than twenty years of building marketing functions for companies in the $20 million to $200 million range.

Option one: build an in-house team

Hiring is the most common approach. It is almost the default.

There is nothing wrong with building an in-house marketing team. The structure usually looks like this. You hire a CMO to own brand strategy, messaging, go-to-market planning, data-driven decision making, and day-to-day leadership. Then you hire a manager to execute, ideally someone with digital chops who understands marketing technology and can handle some copywriting and design with the help of AI.

The advantages are real. You get a team dedicated to your company on a full-time basis. Over time they build institutional knowledge, which leads to better decisions. They learn the personalities of your people and the systems and rhythms of how work actually gets done inside your walls. That knowledge is genuinely valuable and it is the strongest argument for the model.

The disadvantage is that the team's capability is capped at what those two people already know and can learn. Marketing is a discipline of specialties, and a two-person team will have skills gaps. Not probably. With complete certainty.

Which means you outsource anyway. Public relations, which is now a significant lever in getting your firm cited by AI search tools, goes to an agency. Paid media goes to a specialist, because navigating PPC on your own is an expensive education. Design goes to a freelancer or studio when a piece needs to look a notch above a Canva template.

Here is what that stack costs in the current market:

• CMO: $200,000 to $275,000 in base salary. Fully loaded with bonus, payroll taxes, and benefits, figure $250,000 to $345,000.
• Marketing manager: $85,000 to $120,000 in base salary, or roughly $105,000 to $150,000 loaded.
• Public relations support: $5,000 to $15,000 per month, so $60,000 to $180,000 a year.
• Paid media management: $3,000 to $8,000 per month, or $36,000 to $96,000 a year, and that is management only. Media spend is separate.
• Design and creative: $25,000 to $50,000 a year.
• Recruiting: 20 to 25 percent of first-year salary if you use a search firm, which is $40,000 to $70,000 for the CMO seat alone.

Add it up and you are looking at roughly $500,000 to $800,000 in the first year before you spend a single dollar on media, events, or programs. When you total the talent cost alone, it is eye popping, and earning a return becomes difficult even if you make the right hires.

If you hire wrong, the cycle starts over. Worse, the single biggest advantage of going in-house, the fact that these people know your company and your customers, evaporates the day they walk out.

This is a good model for large companies. It is a hard one for the mid-market.

Option two: hire a manager and partner with an agency

Many mid-size firms bring in a solo marketing manager and pair that person with an agency. Some skip the internal hire and outsource entirely.

This can work well. You have someone in-house who knows your company, your people, and your systems, and they work with a partner who can carry the execution load and close skills gaps. The economics are friendlier than a full in-house build:

• Marketing manager: $105,000 to $150,000 loaded.
• Agency retainer: $10,000 to $25,000 per month for a mid-market scope, or $120,000 to $300,000 a year.
• Total: roughly $225,000 to $450,000 a year.

What mid-market leaders need to understand about agencies is that they are tactical. They may tell you otherwise, and they will. Agencies focus on tasks, and often on performance within a single channel like social or paid media. What they do not focus on is how all of the activity comes together to drive a strategic outcome.

Ninety percent of the time, there will be a strategy gap. That gap is a return-on-investment killer.

Paid media may be converting leads, but are they the right leads? Would the company be better served by building a strong foundation for visibility in AI-generated search results instead of chasing quick hits with paid? Those are the judgment calls that experienced marketing strategists and CMOs are paid to make.

One answer is to hire a fractional CMO to close the gap, and that can work well. Budget $5,000 to $12,000 per month for that seat, or $60,000 to $145,000 a year on top of the numbers above.

What I would caution against is hiring a marketing agency to be everything, strategy included. It rarely works. I know this because I am on the other end of the call with frustrated, disappointed CEOs.

Those leaders often describe the same moment. The agency starts coming to them, or to someone else on the leadership team without a marketing background, asking for direction and instruction. The CEO is suddenly the one being asked whether to put the next dollar into paid media or into building a content foundation. That is the moment they realize this setup is not going to get them ahead. If you are the one supplying the marketing judgment, you are not buying strategy. You are buying labor and paying strategy prices for it.

And remember what this model does to your one internal hire. A marketing manager without clear direction and a career path, asked to do too many things both above and below their pay grade, will leave. There are very few marketers who can do all of it well, and the ones who can are not applying for a manager role.

Option three: fractional marketing

This is the least understood of the three models, and full transparency, it is what my firm does. This piece is my honest read of the market, but you should know where I sit.

I built Marketri to solve for the dysfunction I kept seeing in mid-market marketing departments and to make marketing produce a return. The model takes the fractional CMO concept and applies it to every specialty area of marketing. You get a slice of a strategist, a slice of a demand generation lead, a slice of a content specialist, a slice of a marketing operations person. The sum of the slices is a whole marketing team.

The key is what sits underneath. The fractional firms that work well are not a loose collection of freelancers each doing their own piece of the puzzle with different tools and different ways of working. They have employees who follow shared best practices, use a common technology stack, and collaborate to solve problems and act on opportunities together.

With a fractional marketing company, a mid-market B2B firm gets leadership, strategy, data-driven decision making, full-service execution, analysis, and optimization. It is turnkey.

Here is the cost structure:

• Full-service fractional team: $12,000 to $30,000 per month depending on scope, or roughly $145,000 to $360,000 a year.
• Optional internal coordinator or manager: $88,000 to $138,000 loaded, if you want an internal presence.
• Most mid-market engagements land between $180,000 and $300,000 a year, all in.

There are no recruiting fees, no benefits load, no severance risk, and no six-month ramp while a new hire figures out your business.

The model also pairs well with an internal marketing manager or coordinator. You bring in only the skills you are missing, and the internal person is not stuck managing a vendor. They join a team. That is a meaningful difference. They learn, they grow, and in my experience they stay longer.

It is a cost-effective option, and it keeps talent spend lean so more of the budget goes toward actual outreach, which is the part that generates pipeline.

The disadvantage is real and worth naming. A fractional team has other clients and is not sitting on call waiting for your request. The better firms will make you feel like they are, but you are sharing capacity, and that is the tradeoff you are accepting.

The other common concern is that outsourcing so much of the department will prevent the team from truly understanding your business, your model, and your way of working. That is a fair worry, and with the wrong partner it comes true. The firms worth hiring run a serious due diligence process at the start of the engagement and learn what they need to know before they start producing work.

So which one is right for you

The honest answer depends on your scale and on what is actually broken.

If you are large enough to hire the full department, specialists included, hire the department. Institutional knowledge is worth paying for once you can afford the whole team rather than two people and a stack of vendor invoices.

If your strategy is already sound and you need more hands to execute it in one or two channels, an agency paired with a capable internal manager will serve you well.

If nobody at your company can answer the question "what should we be doing and why," you have a leadership and strategy gap. Adding execution capacity will not close it. It will produce more activity at higher cost.

Go back to the picture at the top of this piece. Posts going up. A newsletter going out. Sales getting collateral on request. Competitors circling. If that is your company, the issue was never that you needed more tactics. The issue is that no one is deciding which tactics matter and holding the whole system accountable for growth.

Fix that first. Then choose the model that puts a real strategist in charge, executes quickly without trading away quality, and still leaves you enough budget to go to market. Those three conditions eliminate more options than most CEOs expect.
