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 often comes down to a fractional CMO or a full-time head of growth. They solve different problems. A fractional CMO brings part-time senior strategy and executive judgment; a head of growth is a full-time leader who owns execution. This compares them on scope, cost, time commitment, and fit so you hire the role your company actually needs.
Scope and Focus
Winston Francois: A fractional CMO operates at the strategic and executive level – setting marketing strategy, building the plan, advising leadership, and bringing pattern recognition from many companies, without owning day-to-day execution.
Competitor: A head of growth is typically execution-focused and full-time, owning the hands-on running of growth programs, channel management, experimentation, and the team day to day.
Verdict: If your gap is senior strategy and direction, a fractional CMO fits. If your gap is a full-time leader to own execution and run the team daily, a head of growth fits. The two address different layers of need.
Cost Structure
Winston Francois: A fractional CMO is a fraction of a full-time executive salary – you buy senior expertise for the hours you need, which suits companies that need the judgment but cannot justify a full CMO comp package.
Competitor: A head of growth is a full-time salaried hire with full compensation, benefits, and equity, a larger fixed commitment appropriate when you need full-time execution leadership.
Verdict: The fractional CMO is far more cost-efficient for accessing senior strategy. The head of growth costs more but gives you full-time ownership. Match the spend to whether you need part-time judgment or full-time execution.
Time Commitment and Availability
Winston Francois: A fractional CMO works part-time across the engagement, present for the strategic work and key decisions but not embedded in daily operations or constant availability.
Competitor: A head of growth is full-time and fully embedded, available daily to run programs, manage the team, and respond to the constant operational needs of an active growth function.
Verdict: For daily operational ownership and constant availability, the full-time head of growth is necessary. For strategic direction and executive guidance that does not require daily presence, the fractional model is sufficient and efficient.
Best-Fit Stage and Situation
Winston Francois: A fractional CMO suits companies that need senior strategy, a marketing plan, or help leveling up an existing team, often as a bridge before hiring full-time or when full-time leadership is not yet justified.
Competitor: A head of growth suits companies ready for a full-time leader to own and scale execution, with enough budget, volume, and team to justify embedding a senior operator full-time.
Verdict: Earlier or leaner situations often start with a fractional CMO for strategy and a bridge; companies ready to scale execution full-time hire a head of growth. Many companies use a fractional CMO to define the role before hiring it.
Which Is Right for You?
Hire a fractional CMO if your gap is senior marketing strategy, executive judgment, or leveling up an existing team, and you cannot yet justify or do not yet need a full-time executive – it is the cost-efficient way to access seasoned leadership and often serves as a bridge that defines the full-time role before you hire it. Hire a head of growth if you are ready for a full-time leader to own and scale execution day to day, and you have the budget, volume, and team to justify embedding a senior operator. The two are not really substitutes: one provides part-time strategy and judgment, the other full-time execution ownership. A common smart path is to bring in a fractional CMO to set strategy and shape the role, then hire a head of growth to execute it – so the full-time hire walks into a clear plan rather than 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, bringing pattern recognition from many companies. A head of growth is a full-time leader focused on owning and running execution – channel management, experimentation, and the team day to day. One provides strategic judgment part-time; the other provides full-time execution ownership.
Is a fractional CMO cheaper than a head of growth?
Yes, a fractional CMO is generally far more cost-efficient because you pay a fraction of a full executive salary for senior expertise during the hours you need it, with no full-time compensation, benefits, or equity package. A head of growth is a full-time salaried hire and a larger fixed commitment. The fractional model fits when you need senior judgment but cannot justify or do not yet need full-time leadership.
Should I hire a fractional CMO before a head of growth?
Often, yes. A common smart path is to bring in a fractional CMO to set strategy, build the plan, and define what the full-time role should actually do, then hire a head of growth to execute it. This way the full-time hire walks into a clear plan rather than a blank page, reducing the risk of an expensive mis-hire. It works especially well when you are not yet sure exactly what leadership you need.
When does a company need a full-time head of growth instead?
A company needs a full-time head of growth when its gap is daily execution ownership rather than strategy – when growth programs, channel management, and the team require constant, embedded leadership and availability. This typically applies once you have the budget, volume, and team to justify a full-time senior operator. If you mainly need direction and executive judgment without daily presence, a fractional CMO is sufficient and more efficient.
