An interim CMO (also called a temporary CMO) fills an empty CMO seat for a fixed period, usually until a permanent hire starts. A fractional CMO is an ongoing, part-time senior leader who owns marketing strategy and results without being a full-time employee. Interim is a bridge. Fractional is a model you can run for as long as it pays off.
Key facts
- Average CMO tenure at Fortune 500 companies was 4.3 years in 2024, still shorter than the C-suite average of 4.9 years, according to Spencer Stuart’s 2025 CMO Tenure Study. Marketing seats turn over more often than other executive seats.
- 34% of Fortune 500 companies have no enterprise CMO at all, per the same Spencer Stuart study.
- More than 110,000 people on LinkedIn identified as fractional leaders in 2024, up from about 2,000 two years earlier, according to a Harvard Business Review podcast. Researchers on the same podcast said many fractional executives they spoke with bring 20 to 30 years of experience.
- “Interim CMO” and “temporary CMO” mean the same thing. Both describe a stand-in whose job ends when a defined event happens.
- At The Geisheker Group, fractional CMO leadership starts with a 90-day minimum sprint, run by one of two senior B2B fractional CMOs.
Interim vs fractional CMO: side-by-side comparison
| Attribute | Interim (temporary) CMO | Fractional CMO |
|---|---|---|
| Purpose | Hold the CMO seat during a gap | Provide senior marketing leadership the company does not need, or is not ready for, as a full-time hire |
| Typical engagement length | A few months up to about a year, tied to a defined end date or event | Open-ended; often starts with a 90-day sprint, then runs month to month or longer |
| Scope | Run the existing function: team, budget, campaigns, board reporting | Set strategy, fix the revenue engine, build or reshape the team, and own results |
| Commitment to your company | Dedicated to one company for the length of the assignment | Serves a small number of companies at the same time |
| Employment status | Contractor, sometimes placed by an interim executive firm, occasionally a short-term employee | Independent contractor or firm under a services agreement |
| Reports to | CEO, sometimes the board | CEO, often with a line to the board or PE operating partner |
| How it ends | When the permanent CMO starts, or the leave or project ends | When the company outgrows it and hires full-time, or when goals are met |
| Cost structure | Priced like a full executive salary, plus a placement fee if a firm is involved | A monthly fee that is a fraction of a full-time CMO’s total cost |
| Best for | Keeping a working marketing team running while you search | Building a marketing system that does not exist yet, or fixing one that does not work |

Purpose: hold the seat, or change the results
The cleanest way to tell the two apart is to ask what success looks like on the last day.
An interim CMO succeeds if nothing broke. Campaigns kept running, the team stayed together, the budget was spent as planned, and the new CMO walks into a stable function. That is valuable. It is also a maintenance job by design.
A fractional CMO succeeds if the numbers moved. Pipeline is bigger, cost per qualified lead is lower, and the CEO can see which programs produce revenue. The work is building and fixing, not holding.
So if your marketing works and you just lost the person running it, you want a seat holder. If your marketing does not work, a seat holder will keep it not working for six more months.
Scope and authority
Both roles carry real authority. Neither is an advisor who leaves a slide deck behind.
An interim CMO usually steps into the org chart exactly where the last CMO sat. They manage the direct reports, sign off on spend, run the agency relationships, and present to the board. Because the role is temporary, most interim CMOs avoid big structural changes. Rebuilding a team the next CMO will inherit is rarely in the brief.
A fractional CMO has a different mandate. In my work, the first job is usually diagnosis: where revenue actually comes from, which channels waste money, and whether the team and agencies are pointed at the right buyers. Then we fix the system: positioning, demand generation, sales and marketing alignment, measurement, and the team itself. Structural change is the point, not a side effect.
Engagement length and how each one ends
Interim engagements have a built-in finish line. The end is set by an outside event: a permanent CMO’s start date, a leave ending, or a project being delivered. A typical assignment runs a few months to about a year.
Fractional engagements end differently. They end when the company is big enough, and the marketing system mature enough, that a full-time CMO makes economic sense. Often the fractional CMO helps write the job description and interview candidates, then hands over a working system rather than a holding pattern. If you are weighing that full-time step now, the trade-offs are covered in fractional vs full-time CMO vs agency.
One more practical difference: a fractional engagement needs enough time to show results. That is why we start every engagement with a 90-day minimum sprint. Shorter than that, you get a plan but not proof.
Cost structure in general terms
Interim CMOs are priced against a full-time executive. You are paying for one person dedicated to your company, so the monthly cost lands close to a full CMO salary, and interim placement firms add their own fee on top.
Fractional CMOs charge a monthly fee for senior leadership shared across a small number of companies. The total cost is a fraction of a full-time hire, with no recruiting fee, benefits, or equity grant. At my firm the fee is based on senior experience and outcomes, not time.

Which one fits? A decision checklist for 6 common situations
- Your CMO quit suddenly. If the team is strong, the plan is working, and you will hire a permanent CMO, choose interim. If the departure exposed that there was no real plan or no measurable pipeline, choose fractional. The first 90 days after a departure are covered in detail on our interim CMO services page.
- You are 12 to 24 months from an exit. Choose fractional. Buyers pay for predictable, documented revenue growth. A fractional CMO can build and document that system without adding a permanent executive salary the buyer must take on.
- You are hiring your first marketing leader. Choose fractional. There is no seat to hold, so interim makes no sense. A fractional CMO sets strategy and builds the first version of the function, so your eventual full-time hire inherits something that works. The steps are in how to hire a fractional CMO.
- Marketing needs a turnaround. Choose fractional in most B2B companies. A turnaround is a diagnose-and-rebuild job, which is the opposite of an interim mandate. The exception: a very large marketing organization that needs a dedicated executive on site every day while the fix happens.
- A PE firm just acquired the company. Choose fractional for the value creation plan: setting the growth thesis, fixing measurement, and building pipeline the board can track. Choose interim only if the acquired company lost its CMO at close and has a sound program that simply needs someone running it.
- Your CMO is going on parental leave. Choose interim. The role is defined, the end date is known, and the job is to keep things steady until your CMO returns. A fractional CMO who rewrites strategy during a leave creates problems for the person coming back.
A quick test if you are still unsure: if you can describe the end date in one sentence, you probably need interim. If you can describe the result you need in one sentence, you probably need fractional.
Can one person play both roles?
Yes, and it is common in B2B companies under a few hundred employees. A fractional CMO can cover a CMO gap while a search runs, and many CEOs find that the search becomes unnecessary for a while because the fractional model delivers what they needed.
The reverse is less common. Most interim executives are set up to hold a seat, not to rebuild a function across a small number of clients at once. If you want both stability and change, start with the result you need, and pick the model built for that result.
Frequently asked questions
Is a temporary CMO the same as an interim CMO?
Yes. “Temporary CMO” and “interim CMO” describe the same role: a senior marketing executive who fills the CMO seat for a set period. “Interim” is the term most boards and executive search firms use. Neither term should be confused with a fractional CMO, which is an ongoing part-time model rather than a stopgap.
Can a fractional CMO serve as my interim CMO?
Yes. Many B2B companies use a fractional CMO to cover a vacancy while they decide whether to hire full-time. The difference is the mandate: tell the fractional CMO whether you want the seat held steady or the function improved, because those are different jobs.
Which is cheaper, an interim CMO or a fractional CMO?
A fractional CMO almost always costs less in total, because you share senior leadership rather than paying for a dedicated executive plus any placement fee. An interim CMO is priced close to a full-time CMO salary for the months they are in the seat. See how fractional CMOs charge for the common pricing models.
Does an interim CMO or a fractional CMO manage my marketing team?
Both can. An interim CMO steps directly into the reporting line and manages the team day to day. A fractional CMO leads the team and agencies through clear priorities, a measurement plan, and regular reviews, and often reshapes the team as part of the work.
Can an interim CMO become the permanent CMO?
Sometimes, if both sides agree and the person fits the long-term role. Many interim executives prefer short assignments, so do not assume it. If you think you might want to convert, say so before the engagement starts and agree on how the decision will be made.
How long should a fractional CMO engagement last before I see results?
Plan on at least 90 days to diagnose the system, fix the biggest leaks, and start measuring pipeline impact. That is why our engagements start with a 90-day minimum sprint. Many companies continue well past that because the model keeps paying off until they are ready for a full-time CMO.
