A fractional CMO is a senior marketing leader who works for your company part time, usually a few days a month, on a retainer. They own what a full-time CMO owns: strategy, budget, team and results.
You get that experience for a fraction of the cost, without a long hiring search. Here's what the role looks like, what it costs and how to tell if it fits you right now.
A fast-growing way to lead
What a fractional CMO actually does
The scope is the same as a full-time CMO. Only the hours change, so the good ones spend them on decisions and leave the doing to the team.
Strategy
Who you sell to, what you say, which channels get the money.
Budget
Where every euro or dollar goes, and what it has to bring back.
Team
Leading marketers, freelancers and agencies. Hiring the next person.
Numbers
A small set everyone trusts, reviewed every week.
Accountability
Reporting to the CEO or board like any other executive.
Same scope as a full-time CMO. Only the hours change.
Fractional, consultant, agency or interim?
| Fractional CMO | Consultant | Agency | Interim CMO | |

| Length | Months to years | Weeks | Ongoing | Until a hire |
| Leads your team | Yes | Rarely | No | Yes |
A normal month
Most retainers run 10 to 20 hours a week5. The rhythm matters more than the hours.
Weekly
A check-in with the CEO and a team meeting. One dashboard, a few numbers.
Monthly
Spend and results reviewed. A decision on what moves next.
Quarterly
A plan reset with the leadership team.
What it costs
Monthly retainers by company stage, against the base salary of a US marketing manager, one level below a CMO.
Run your own numbersIs it right for you?
A good fit when
- The founder still runs marketing
- You spend real money and can't say what works
- You're about to raise, launch or enter a market
- A full-time CMO is a year or two away
Hire full time when
- A large team needs daily leadership
- The channels that work are clear and need scale
- Marketing is the core of how you compete
A good fractional CMO will help you hire that person.
