If you search for fractional marketing leadership, you'll find "fractional CMO" everywhere. I call myself a fractional head of growth instead. That's not branding. It's a different scope, and picking the wrong one is an expensive way to find out.
The short answer: hire a fractional CMO when you need someone to own the whole marketing function, brand and team included. Hire a fractional head of growth when the problem is pipeline: what creates it, what converts it, and why it isn't moving.
What each role owns
| Fractional CMO | Fractional head of growth | |
|---|---|---|
| Core question | Is the marketing function set up to win? | Why isn't pipeline growing, and what fixes it? |
| Owns | Brand, positioning, narrative, team, budget, agencies | Pipeline, conversion, channel economics, experiments |
| Typical outputs | Brand platform, marketing org design, annual plan | Pipeline definition, ranked backlog, channel scorecard, tested programs |
| Measured on | Market position, team health, plan delivery | Qualified pipeline, conversion rates, pipeline per dollar |
| Works most with | CEO, board, marketing team | CEO, CRO or sales leader, marketing team |
| Best fit when | Marketing needs a leader and a structure | Marketing has activity but pipeline isn't moving |
The two overlap. Good growth leaders care about positioning, because a weak position makes every channel more expensive. Good CMOs care about pipeline, because the board does. The difference is where they start and what they're accountable for.
When you need a fractional CMO
- You have no marketing leader and a team of three or more who need one.
- You're entering a new market or category and need a narrative from scratch.
- Brand, PR and analyst relations matter to how you win deals.
- The board wants a marketing plan and budget owned by a named executive.
When you need a fractional head of growth
- Spend is up and qualified pipeline is flat. (I wrote a diagnostic for exactly this.)
- Marketing and sales argue about lead quality and nobody owns the definition.
- You have channels running but can't say which ones create pipeline.
- Your team has AI tools, but what comes out isn't good enough to ship.
- You're heading toward a raise or an exit and need growth numbers that hold up in diligence.
The title matters less than the scope
Titles in fractional work are loose. Some "fractional CMOs" are really demand-gen operators. Some "heads of growth" only advise. Before you hire either, get answers to these:
- What will you own, and what will you only advise on? A leader who owns decisions is a different hire from a consultant who recommends.
- What will you have shipped by day 30? A real answer names deliverables, not "discovery."
- How will we measure you? If the answer is MQLs or impressions, keep looking.
- Who does the work? You, or a team behind you? Many fractional offers are agencies with an executive face.
- What do we keep when you leave? Playbooks, definitions, dashboards, workflows. If the answer is "nothing written down," you're renting, not building.
- What have you done at a company like ours? Same stage, same motion, ideally through a raise or an exit.
What it costs
Published 2026 market ranges for fractional marketing leaders run roughly $3,000 to $25,000 a month, depending on scope and company size. I've broken down the sources and my own pricing on the pricing page. Short version: price follows scope and ownership more than title.
Why I chose "head of growth"
I've led marketing and demand generation at six B2B companies, three of them through acquisitions. The work that mattered most every time was the pipeline system: the definition, the ICP, the channel economics, the conversion path, the weekly rhythm. That's what I own in an engagement. Positioning and messaging are part of it, because they make every channel work harder, but I'm not a brand agency and I won't pretend to be one.
If you need a full marketing org built, a fractional CMO may be the better hire. If the number isn't moving and nobody can explain why, let's talk.
Frequently asked questions
What's the difference between a fractional CMO and a fractional head of growth?
Scope. A fractional CMO typically owns the whole marketing function, including brand, team and budget. A fractional head of growth owns pipeline and conversion: definitions, channel economics, experiments and the system that produces qualified pipeline.
Which is better for a B2B SaaS company at $5M–$40M ARR?
It depends on the problem. If marketing lacks a leader and structure, a fractional CMO. If marketing is active but qualified pipeline isn't growing, a fractional head of growth. Many companies at this stage need the second first.
Can a fractional head of growth work with my existing marketing team?
Yes. That's the usual setup. The growth leader owns the thesis, the backlog and the definitions; the team owns day-to-day execution and the tools.
How do I avoid hiring a fractional leader who only gives advice?
Ask what they'll own versus advise on, what they'll ship in the first 30 days, and what you keep when they leave. Ownership and documented systems are the difference between a leader and a consultant.
