Three Very Different Models
When a growing company decides they need marketing help, they usually face the same three options: hire a marketing agency, bring in a consultant, or get a fractional CMO. These sound like variations of the same thing. They're not. Each model has fundamentally different strengths, costs, and failure modes.
What a Marketing Agency Does (and Doesn't Do)
An agency runs campaigns. They're operators — they execute on a predefined strategy, manage ad accounts, produce content, and report on results. A good agency has specialists (media buyers, designers, copywriters, data analysts) who work on your account as a team.
Best fit: You know what you want to do — run Meta ads, build SEO content, manage email campaigns — and you need a team to execute it well. You have a clear goal (leads, sales, traffic) and a budget allocated to hitting it.
Warning signs an agency isn't what you need: You're not sure what channels to focus on. You don't have a clear ideal customer profile. You're hoping the agency will figure out your strategy for you. Agencies execute strategy; they rarely define it.
Typical cost: $2,000-$15,000+/month depending on scope and channels.
What a Marketing Consultant Does
A consultant diagnoses and advises. They look at your current marketing, identify what's working and what isn't, and tell you what to do differently. They might help you define your ICP, choose the right channels, build a go-to-market plan, or audit your funnel.
Best fit: You have some marketing happening but it's not working and you're not sure why. You need an experienced outside perspective to diagnose the problem before you start spending more money on execution.
Warning signs a consultant isn't what you need: You already know what's wrong and you need someone to fix it. Consultants give you recommendations; execution is still on you.
Typical cost: $200-$500/hour, or $5,000-$20,000 for a defined engagement.
What a Fractional CMO Does
A fractional CMO is a senior marketing leader who works with you part-time — usually 1-3 days per week — as an embedded member of your team. They own the marketing strategy, lead the team (internal or agency), and are accountable for results in a way a consultant typically isn't.
Best fit: You're past founder-led marketing ($2M-$20M revenue range is typical), you need senior marketing leadership, but you're not ready to hire a full-time CMO at $200,000+ per year. A fractional CMO gives you the strategy and leadership at roughly 30-40% of the full-time cost.
Warning signs a fractional CMO isn't what you need: You need someone available 40 hours/week. You need execution more than strategy. Your team isn't ready to be led — you just need someone to run campaigns.
Typical cost: $8,000-$25,000/month for 2-3 days/week.
The Decision Framework
Ask yourself three questions:
- Do I know what I want to do, or do I need help figuring that out? If you know (run ads, build content), hire an agency. If you don't, hire a consultant or fractional CMO first.
- Do I need execution or strategy? Execution → agency. Strategy → consultant or fractional CMO.
- Do I need someone accountable to results, or someone to advise? Accountable → fractional CMO (they're in the room). Advisory → consultant.
The Most Common Mistake
Companies hire an agency when they need a fractional CMO. They have no clear strategy, no defined ICP, no working funnel — and they sign a 3-month agency contract hoping the agency will figure it all out. The agency executes against vague goals, results disappoint, and both sides are frustrated.
If your marketing fundamentals aren't solid, fix those first. Spend $10,000 on a consultant to build your strategy, then spend $5,000/month on an agency to execute it. That sequencing works. The reverse usually doesn't.
Can You Use More Than One?
Yes, and many growing companies do. A fractional CMO sets strategy and manages 2-3 specialist agencies (one for paid ads, one for content/SEO, one for email). The fractional CMO provides the senior leadership; the agencies provide the specialized execution. This model gives you a full marketing function without the overhead of a full internal team.
