Hire a fractional CMO when your growth work fills two or three days a week and you need the number to move this quarter. Hire a full-time CMO when the work fills five days, you have a team to manage, and you can absorb about a year before the hire compounds.
It starts in a board meeting. Someone says it is time to hire a CMO, and a fortnight later a job description comes back from the recruiter.
Read it closely and it describes a person who does not exist at your stage. Brand and demand generation and lifecycle and product marketing and analytics. A team of ten to build and lead.
You have three people in marketing and a tracking setup nobody trusts. That document is a portrait of the last company your board member sat on the board of.
I have sat in the fractional seat while a search ran in the background, and I have run marketing as the first executive a company ever hired.
An outside agency turns on different questions, which I work through in the agency comparison. The choice here is between two versions of the same seat.
How long does a full-time CMO search actually take?
About six months from the board meeting to a signed offer, if the search goes well. A retained firm, a long list, panel loops, a founder who meets four finalists and warms to none of them. Then a partial restart because the bar moved.
Add the notice period the person owes their current employer, then the ramp, which industry norms put at roughly six more months. The first two of those go on discovering that the pipeline figure in the board deck has three definitions depending on who exported it.
Almost nobody puts that window in the plan. The plan says CMO hired in Q2, as though the hiring and the impact were the same event. They are a year apart.
You do not get an honest verdict on an executive hire until somewhere around month eighteen, once their bets have had time to pay or fail.
A second clock runs underneath: the founder is learning to supervise a marketing executive for the first time, which is why I install a reporting contract in the first week.
What each one actually costs
Loaded with base, bonus, equity and benefits, a full-time marketing executive costs $250,000 at the bottom of the market and $450,000 at the top, or roughly $21,000 to $37,500 a month. The search fee sits on top, billed by a retained firm as a percentage of the first year's pay.
My own work opens at $20,000 a month, priced for owning the growth number rather than advising on it. Scope, the size of the team reporting in, and whether the mandate carries hiring and board reporting all carry it higher, which I break down on the pricing page.
So money is a weak argument here, and any operator leading with it is hoping you will not run the sums.
What the same spend buys is different. Two days a week of an operator more senior than that figure would buy you permanently, starting the week you sign.
Do you have enough work to fill an executive's week?
Executive time is sold in weeks and consumed in decisions, so count the decisions. The companies I work with are past product market fit and usually north of $15M in revenue, where leadership becomes the constraint rather than headcount.
Even with three or four marketers underneath you, the work that truly needs a marketing executive is a short list: the channel allocation call, the offer and pricing question, a round of creative direction, the number the founder and the board read, and two coaching conversations.
Founders read a list like that and picture a full week, because every line on it sounds heavy. Time it across a month rather than imagining it.
Ask whether you have enough scope to fill an executive's week. Most companies at this stage have enough scope to fill two very good days.
The expected failure mode is an empty calendar. That is never what happens. A capable executive with three unfilled days fills them, and the things they reach for cost money.
A rebrand nobody asked for. A platform migration. Most often a team, hired fast, because a marketing leader with no organization under them feels like a leader in title only, and filling the chairs is the quickest way to make the seat feel real.
The hiring order I actually use adds each person to clear whatever is capping growth that month. Hiring to justify a title runs it backwards, and you find out two quarters later when the cost base has doubled and the number has not.
What a wrong hire actually costs
Marketing executives carry the shortest average tenure in the C-suite. Price a wrong one honestly and the pay is the small part.
There is the search, run twice. The year the person sat in the seat. The notice on the way out.
Then the part that genuinely hurts. An executive builds an organization in their first two quarters, so unwinding the hire means unwinding the people they brought in and the strategy a whole team executed faithfully.
And the eighteen months, which you cannot re-run. Somebody with your product and a working growth function got those months to compound while your calendar was full of interviews.
None of it looks like damage while it happens. The org chart fills in. The decks improve.
The fractional version of being wrong is smaller by design. Thirty days of notice closes it, and the dashboards and the weekly rhythm stay behind because they were built into your systems rather than one person's head. That shape, diagnose then build then hand off, is how every engagement I run is structured.
When is a full-time CMO clearly the right answer?
There are situations where I tell a founder to run the search, and I say so on the first call. Four of them.
- Marketing past eight people, with managers who need coaching and career paths every day.
- Brand, communications, PR and events as a standing function rather than a project.
- A large round or a sale process, where the leader sits in diligence and carries the story for years.
- A sales motion with long cycles and named accounts that needs marketing in the room weekly.
In those cases fractional is the wrong shape, and an operator who tells you otherwise is selling.
The rule I give founders
The test takes an afternoon. Five steps, in this order.
- Count the hours. Total every decision from the last month that genuinely needed a marketing executive. Under two days a week and the seat is not full yet.
- Check the measurement. If nobody trusts the numbers, no leader can be judged against them, so that work happens first either way.
- Name the number the hire owns. If you cannot write one sentence describing the metric this person answers for, the job description is not finished.
- Price the whole window. Set eighteen months of an operator against a search, a ramp and a year of executive pay, then ask which has the number moving in month three.
- Set the review date. Put a date in the calendar where the engagement converts to a permanent seat, ends, or writes the job description for one.
A year into an engagement, the tracking is honest, every channel has been graded, and you know precisely which two problems remain unsolved. The board's fantasy becomes a scorecard: the number, the system producing it, and what nobody has cracked yet.
Now run the search. Your finalist walks into figures they can trust and a team already running a weekly rhythm, so the ramp gets measured in weeks.
The best outcome of a fractional engagement is that it makes your eventual full-time hire succeed.
That is roughly what happened at FX Replay. I came in on a consulting engagement and the CMO seat followed, after a year of the company watching me work on its own problems.
No interview loop buys that. Six months of process is an expensive way to learn less about a person than one quarter of watching them work.
Your board is right that you need marketing leadership. The estimate goes wrong on the size of the job, sized against a company several stages ahead of yours.
Buy the job you have today. Then revisit it in two quarters, when the job is bigger.
If a board conversation has you writing a CMO job description, the cheapest hour you can spend is counting the scope before the search opens. Let's talk.
