A chief growth officer owns the commercial picture across sales and marketing: which constraint matters, which work is in the next 90 days, and whether the team is judging the right number. A fractional chief growth officer, also called a fractional head of growth or fractional CGO, holds that remit part-time.
People asking what a chief growth officer does are usually trying to separate the role from a marketing leader, a sales leader, or a consultant. The useful test is ownership. A consultant can recommend. A fractional CMO or fractional marketing director usually owns marketing delivery. A chief growth officer owns the decision between those functions, then stays close enough to see whether the decision changed the pipeline.
That definition matters because “growth” is often used to describe a collection of unrelated tasks. Paid media, outbound, content, conversion work and reporting can all be active while nobody owns the decisions between them. The full operating version of this role is a fractional chief growth officer engagement. When the team should keep ownership, the work is business growth consulting instead.
Ownership starts before the channel
The first responsibility is not choosing a tactic. It is forming a useful view of the system:
- Which customers are most valuable to pursue now?
- Is the offer clear enough to create a response?
- Where does qualified demand currently come from?
- Where does pipeline leak or stall?
- Which evidence is good enough to make a decision?
- What should the team stop doing?
If those questions are unresolved, adding a channel usually adds motion before it adds clarity.
What the role normally owns
The exact boundary should be agreed for each company, but I would expect a fractional growth remit to include five things.
1. The diagnosis
Growth problems rarely arrive with clean labels. “We need more leads” could mean the target market is too broad, the offer is weak, conversion is poor, qualification is inconsistent, or the pipeline definition is flattering activity that never becomes an opportunity.
The role needs to separate the symptom from the constraint.
2. The order of operations
A useful 90-day plan is not a longer backlog. It is an argument about sequence: what matters now, why it comes first, what evidence would change the choice and which reasonable ideas must wait.
3. Cross-functional alignment
Pipeline crosses boundaries. Marketing can create demand that sales does not trust. Sales can reject leads using criteria marketing never saw. Both teams can report success while revenue remains unmoved.
The fractional leader should make the shared definitions, decisions and handoffs explicit.
4. The operating rhythm
Plans drift without consequence. A weekly growth review should connect actions to evidence and evidence to the next decision. It should answer: what changed, what did we learn, what is blocked, and who owns the next action?
5. The transfer of ownership
Fractional leadership should not create permanent dependence. Useful systems are documented, internal owners become stronger, and the company gets a clearer view of the permanent team it needs.
What it does not automatically own
A Head of Growth is not an expert in every acquisition, product, sales and retention discipline. It is better to be explicit about where specialist depth is required.
The role also should not absorb responsibilities that properly belong to a sales leader, product leader or founder merely because “growth” sounds broad. Ambiguous ownership creates more meetings, not more growth.
The practical test
If you only need someone to execute a known channel, hire the right specialist or agency. If you need a defined analysis, use a consultant or start with a Growth Diagnostic. If the enduring role is already clear and full-time, make the permanent hire.
Fractional leadership is most useful in the gap: the business has enough traction and complexity to need senior ownership, but the right permanent structure is not yet obvious.
If that sounds like the situation you are in, tell me what is getting in the way.
