Fractional CMO vs. Marketing Agency: Which One Does Your Business Need?

They Are Not the Same Thing

We get this question constantly: "Should we hire a fractional CMO or a marketing agency?" The answer depends on what you need, but first, let us be clear about what each one actually is — because most people conflate them.

A marketing agency is a team that executes marketing activities. They run your ads, manage your social media, build your website, write your content, or handle your SEO. They are specialists in doing marketing.

A fractional CMO is a senior marketing executive who works with your company part-time. They build your strategy, manage your team or agencies, allocate your budget, and report on performance. They are a leader who is accountable for whether marketing produces business results.

An agency is a vendor. A fractional CMO is a member of your leadership team. Those are fundamentally different relationships with fundamentally different outcomes.

When You Need an Agency

Agencies are the right choice when you have a clear strategy and need skilled execution. The key word is "clear strategy." If you already know what channels to invest in, what your messaging should be, and what results to expect, an agency can execute that plan efficiently.

Specifically, agencies work well when:

• You need specialized skills you do not have in-house. Paid media management, SEO, video production, web development — these require specific expertise. An agency with a team of specialists will almost always outperform a single generalist on your payroll.
• You have a marketing leader managing them. Someone internal — a VP of Marketing, a Director, or a fractional CMO — who sets the strategy, defines the KPIs, reviews the work, and holds the agency accountable. Without this, agencies drift.
• The scope is well-defined. "Manage our Google Ads account and generate X leads per month at Y cost per lead." That is a clear brief an agency can execute against. "Help us grow" is not.
• You have the budget for the right agency. Good agencies are not cheap. A solid digital marketing agency charges $5,000-$15,000+ per month. If you are shopping for the cheapest agency, you will get the cheapest work.

When You Need a Fractional CMO

A fractional CMO is the right choice when you do not have a marketing strategy, do not have marketing leadership, or both. They are not a replacement for an agency — they are the person who decides whether you need an agency, which one, and for what.

Specifically, a fractional CMO makes sense when:

• Nobody owns marketing at the senior level. If the CEO is making marketing decisions, the company has outgrown that model. A fractional CMO takes ownership of the entire marketing function.
• You are not sure what your marketing strategy should be. An agency will happily sell you whatever you ask for. A fractional CMO will tell you what you should be asking for in the first place.
• You have agencies but they are not producing results. Nine times out of ten, the issue is not the agency — it is the absence of someone on the client side who can manage them. A fractional CMO manages the relationship, sets the expectations, and holds them accountable.
• You need marketing leadership but cannot justify a full-time CMO salary. A full-time CMO costs $250K-$350K. A fractional CMO costs $8K-$20K per month. For companies between $3M and $50M in revenue, the fractional model gives you the leadership without the overhead.
• You are going through a transition. PE acquisition, rapid growth, market expansion, product launch. These moments need strategic marketing leadership, not just campaign execution.

The Dangerous Middle Ground

The worst outcome is hiring an agency when you need a fractional CMO. This is the scenario we see most often, and it plays out predictably:

1. Company needs marketing help. They search "marketing agency" because that is the term they know. 2. Agency pitches a package — some combination of ads, SEO, content, social. It sounds comprehensive. 3. Company signs. Agency starts executing. First few months feel productive. 4. Six months in, the company is not sure what marketing is producing. The agency sends reports, but nobody internally knows how to evaluate them. 5. The CEO starts attending agency calls. They do not have the expertise to know if the agency is doing good work or not. 6. Twelve months in, the company fires the agency and looks for another one. The cycle repeats.

The missing piece was never the agency. It was someone on the client side who could set the strategy, manage the relationship, and evaluate the work. That someone is a marketing leader — fractional or full-time.

When You Need Both

Most companies between $5M and $50M in revenue need both: a fractional CMO for strategy and leadership, and one or more agencies for specialized execution. The fractional CMO sets the plan. The agencies do the work. The fractional CMO manages the agencies and reports to leadership.

Here is what that looks like in practice:

• Fractional CMO ($10K-$15K/month): Sets the marketing strategy, manages the budget, selects and manages agencies, builds internal team where needed, reports to the CEO and board.
• Digital agency ($5K-$10K/month): Manages Google Ads, Meta Ads, and SEO. Operates within the strategy and budget set by the fractional CMO.
• Content contractor or agency ($2K-$5K/month): Produces blog content, case studies, and email newsletters based on the content strategy built by the fractional CMO.

Total cost: $17K-$30K/month — significantly less than a full-time CMO ($25K-$30K/month when you include benefits and overhead) plus agencies. And you get better results because there is senior leadership coordinating everything.

The Questions to Ask Yourself

Here is a quick diagnostic:

Do you have a clear marketing strategy that connects activities to revenue targets?

• Yes: You might just need an agency to execute it.
• No: You need a fractional CMO to build one.

Is someone with real marketing experience evaluating your marketing performance?

• Yes: Your current setup may be working.
• No: You need marketing leadership before you invest more in execution.

Can you explain what your marketing spend produced last quarter in terms of leads, pipeline, and revenue?

• Yes: Your measurement is working.
• No: You need someone to fix your measurement before you spend another dollar.

Have you been through 2+ agencies in the last 3 years?

• Yes: The problem is probably not the agencies — we explain why in why most marketing agencies fail their clients. It is the absence of client-side leadership.
• No: Your agency relationship might be working fine.

The Decision Framework

Here is the simplest way to think about it:

• You know what to do, you need someone to do it. Hire an agency.
• You do not know what to do. Hire a fractional CMO.
• You sort of know what to do, and you have agencies, but it is not really working. Hire a fractional CMO to diagnose the problem and fix it — which might mean keeping your current agencies, replacing them, or restructuring the whole approach.
