Fractional CMO vs Head of Growth
When a growth-stage company knows marketing needs senior leadership but is not sure what to hire, the choice usually comes down to a fractional CMO or a full-time head of growth. They are not competing for the same job. A fractional CMO sets strategy and brings executive judgment part-time; a head of growth is a full-time operator who owns the execution engine day to day. This breaks down scope, cost, time commitment, and fit so you hire the role your company needs right now, not the title that sounds more senior.
Scope and Focus
Winston Francois: A fractional CMO works at the strategic layer – setting the marketing plan, prioritizing channels, advising the founder or CEO, and bringing pattern recognition from other companies at your stage, without sitting in the daily execution.
Competitor: A head of growth is a full-time execution owner – running channel programs, building and reviewing experiments, and managing the growth team's day-to-day output.
Verdict: If the gap is direction – what to prioritize and why – a fractional CMO fills it. If the gap is a full-time owner running the machine, a head of growth fills it. Most companies actually have one gap at a time, not both.
Cost Structure
Winston Francois: A fractional CMO costs a fraction of a full executive package – you pay for senior judgment on the hours you need it, which is why it fits companies that need the strategy but cannot yet justify a six-figure CMO hire.
Competitor: A head of growth is a full-time salaried role with benefits and typically equity, a real fixed cost that only pencils out once there is enough budget and volume to keep a full-time operator busy.
Verdict: Dollar for dollar, the fractional CMO is the cheaper way to buy senior judgment. The head of growth costs more but buys dedicated ownership. Size the spend to the actual gap, not to whichever title feels more impressive on paper.
Time Commitment and Availability
Winston Francois: A fractional CMO shows up for the strategic work and the key decisions – plan reviews, hiring calls, channel bets – not for daily standups or being on call.
Competitor: A head of growth is embedded full-time, available every day to run programs, unblock the team, and respond to whatever the growth function throws at them that week.
Verdict: Daily operational ownership needs a full-time head of growth – there is no substitute for someone in the room every day. Strategic direction that does not require daily presence is exactly what the fractional model is built for.
Best-Fit Stage and Situation
Winston Francois: A fractional CMO fits companies that need a real marketing plan or need an existing team leveled up, often as a bridge before a full-time hire is justified or even defined.
Competitor: A head of growth fits companies ready to scale execution full-time, with the budget, pipeline volume, and team size to keep a senior operator busy and accountable.
Verdict: Earlier and leaner companies tend to start with a fractional CMO to build the plan; companies with proven demand and headcount to spare hire a head of growth to run it. The two are often sequential, not competing.
Which Is Right for You?
Hire a fractional CMO when the gap is a real marketing strategy, executive judgment on channel bets, or leveling up a team that already exists, and you cannot yet justify – or do not yet need – a full-time executive. It is the cheaper way to get seasoned leadership in the door, and it often ends up defining the full-time role before you post the job. Hire a head of growth when you are ready for a full-time owner to run and scale execution day to day, and you have the budget, pipeline volume, and team to keep that person accountable to real output. These are not really substitutes for each other – one buys part-time strategy and judgment, the other buys full-time execution ownership. The path we see work most often: bring in a fractional CMO to set the plan and shape the role, then hire a head of growth to run it, so the full-time hire inherits a plan instead of a blank page.

Frequently asked questions
What is the difference between a fractional CMO and a head of growth?
A fractional CMO is a part-time senior executive who sets marketing strategy, builds the plan, and advises leadership without owning daily execution, drawing on pattern recognition from other companies. A head of growth is a full-time leader focused on running execution – channel management, experimentation, and the team day to day. One buys strategic judgment part-time; the other buys full-time execution ownership.
Is a fractional CMO cheaper than a head of growth?
Yes, generally by a wide margin. You pay a fraction of a full executive salary for senior expertise during the hours you actually need it, with no full-time comp, benefits, or equity package attached. A head of growth is a full-time salaried hire and a larger fixed commitment. Fractional makes sense when you need the judgment but cannot yet justify full-time leadership.
Should I hire a fractional CMO before a head of growth?
Often, yes. A fractional CMO can set the strategy, build the plan, and define what the full-time role should actually own, then you hire a head of growth to execute against it. The full-time hire inherits a clear plan instead of a blank page, which cuts the risk of an expensive mis-hire. This sequence is especially useful when you are not yet sure what kind of leader you need.
When does a company need a full-time head of growth instead?
When the gap is daily execution ownership, not strategy – when channel programs and the team need constant, embedded leadership and availability. That usually means you already have the budget, volume, and team size to keep a full-time senior operator busy and accountable. If what you mainly need is direction and judgment without daily presence, a fractional CMO covers it more efficiently.
