A fractional CMO engagement review is the scheduled decision point at the end of each sprint where a B2B company renews the engagement, narrows its scope, or ends it, judged against the KPI baseline agreed at the start. Most companies expect the decision to turn on performance. In practice the clearest end signal is not a number at all, it is the moment the company starts following someone else’s marketing judgment instead of the person it hired.
Key facts at a glance
- The decision point is the end of the agreed 90 day sprint, measured against the baseline set in the first 30 days, and the targets are framed as goals rather than guarantees from the day the contract is signed, per Peter Geisheker.
- The end signal that matters is political rather than financial. When a company follows a different adviser’s judgment over its fractional CMO’s, the engagement is finished regardless of what the budget still allows, per Peter Geisheker.
- Scope at The Geisheker Group, Inc. has two tiers: marketing strategy plus marketing team and vendor management, or marketing strategy alone at a somewhat lower fee. Execution is never in either tier.
- 42% of interim executive projects now last longer than six months, up from 27% in 2021, and 16% run beyond a year, per the 2026 Talent Lens Survey from the executive search firm Heidrick & Struggles, fielded August 2025 among 3,810 independent executives.
- Average CMO tenure in the S&P 500 is 4.1 years against 5.0 years for all C-suite roles at those companies, per Spencer Stuart, January 2026, so a fractional engagement running into a second year is not unusually long by the standard of the job it covers.
- When executives cut expenses after a profit miss, marketing is cut 45.4% of the time, more often than other expense categories, per The CMO Survey’s 35th edition, fielded January 2026 with 308 responding marketing leaders.
- Fractional CMOs overstay engagements too, and the reasons are loyalty and attachment to a program that is working rather than money, per Peter Geisheker.

What happens at the end of a 90 day fractional CMO sprint?
At the end of a 90 day fractional CMO sprint, the engagement reaches a scheduled gate where the company decides whether to continue. The review compares the KPI baseline measured in the first 30 days against the target agreed with the chief executive, then covers what worked, what did not, and what the next sprint would do differently. The decision belongs to the company.
Peter Geisheker, founder of The Geisheker Group, Inc., describes how the gate works: “I make it clear from the beginning of contract that the numbers we choose are goals that we will all strive to hit, but like in all things in life, there is no guarantee. When numbers are not what we want them to be I discuss what we have done, what has worked well, what has not worked well, and my plan for the next 90 day sprint to hit the new numbers. At this point the client can choose to hire me for another 90 day sprint or not renew the contract and we go our separate ways.”
Two things in that are worth a buyer’s attention. The first is that the targets are goals rather than guarantees, stated at signature rather than at the review, which protects the fractional CMO as much as it sets the company’s expectations. A buyer is entitled to notice that, and the fair counterweight is that the target is set against a measured baseline rather than invented. The second is that the gate arrives on a schedule. A contract with no review date defaults to indefinite renewal, and indefinite renewal serves the marketer rather than the company.
The most common real outcome at the first gate is neither a clean win nor a clean failure. The numbers have usually moved and usually by less than hoped, partly because the first 30 days go to audit and baselining rather than to results. Treating a partial result as a failure produces churn through marketing leaders and compounds nothing, and the cost of that churn shows up a year later rather than at the point of the decision.
When should you renew a fractional CMO engagement?
A B2B company should renew a fractional CMO engagement when the baseline KPIs have moved in the agreed direction and the next set of problems still needs senior marketing judgment rather than execution capacity. Renewal says the diagnosis was right and the work is unfinished. It is not a reward for effort and not a verdict on whether the working relationship is pleasant.
The renewal test has two parts and companies routinely apply only the first. The first is whether cost per lead, sales qualified leads, and cost to acquire a customer moved against the baseline. The second is whether the remaining work is still a leadership problem. A company whose positioning is settled, whose channels are proven, and whose reporting runs itself does not need a fractional CMO next quarter. It needs someone to operate the system, which is a cheaper hire. Renewing out of momentum is how a good engagement becomes a retainer nobody can justify.
Judge the numbers against the scorecard agreed at 30, 90, and 180 days, then ask the second question. Reversing that order turns the review into a conversation about personalities.
One figure is worth holding during a renewal debate. Average CMO tenure in the S&P 500 is 4.1 years against 5.0 years for all C-suite roles at those companies, and only chief operating officers turn over faster at 3.3 years, per Spencer Stuart’s January 2026 study of the 346 named CMOs of S&P 500 companies as of June 30, 2025. A fractional engagement in its second year is roughly half the tenure of the full-time role it stands in for.
When should you narrow the scope instead of ending it?
A B2B company should narrow a fractional CMO engagement when it wants to take back a part of the job rather than replace the judgment behind it. At The Geisheker Group, Inc. the scope has two tiers, and the axis between them is management rather than execution, because execution is never inside the engagement at any price.
Peter Geisheker, founder of The Geisheker Group, Inc., draws the boundary plainly: “I make it very clear that I am marketing strategy and marketing team/vendor management. I am not going to do execution too. That is what marketing employees and vendors are for. I am the marketing General, not a soldier on the ground.”
That boundary is what makes the narrowing decision legible. A company cannot reduce a fractional CMO engagement by taking execution off it, because execution was never on it. What a company can take back is the management layer: directing the in-house marketers and holding the agencies to account. Companies usually want that when they have hired a marketing manager capable of running the team and the vendors themselves, and at that point the engagement becomes strategy only.
Peter Geisheker states the rule and the limit on it: “Yes, there are times when I will change my pricing such as if they want to switch from having me perform marketing strategy and team/vendor management to just strategy and they will handle managing their team and vendors. At that point I am willing to lower my fee somewhat. Or, if the opportunity is no longer of value to me, I will leave and they can hire a new Fractional CMO. I am running a business so I need to do what is financially in the best interest of my business.”
Read the last sentence as the disclosed interest it is. A fractional CMO deciding whether a narrower engagement is worth running is making a business decision about their own firm, and a buyer should expect that rather than be surprised by it. The practical consequence is that narrowing has a floor. Below some scope the engagement stops being worth either side’s time, and a company planning to shrink the work repeatedly should assume it ends at the second or third step rather than the fifth. Clarity about what each price level buys is what keeps that conversation honest, and a written decision-rights matrix is what stops a narrowing from quietly becoming a stall.

When should you end a fractional CMO engagement?
A B2B company should end a fractional CMO engagement when the company has stopped trusting the marketing judgment it hired. That sounds softer than a performance test and it is actually harder, because it shows up earlier and it is not negotiable. Budget cuts, missed targets, and strategy disagreements are all survivable. A company following a different adviser’s judgment on marketing is not.
Peter Geisheker, founder of The Geisheker Group, Inc., states the test directly: “The client chose the advice of the new CFO instead of me. That showed me they did not trust or respect me. Once that happens the relationship is over.”
The situation behind that is worth describing, because the visible trigger and the real reason were different things.
Peter Geisheker describes the engagement he ended: “I was working for a client that hired a new CFO. That CFO wanted to see ROI quarterly while we had a long sales cycle. I tried to explain that you cannot run quarterly numbers on a sales cycle that can last 6 to 18 months. He would not listen and cut over 50% of my advertising budget leaving me with very little resources to accomplish the company’s goals. So, I stopped working with that client. A few months later that new CFO was fired.”
Note what was not the deciding factor. Asked where a budget cut stops being survivable, Peter Geisheker does not answer with a percentage. A 50% cut was the symptom. The reason for leaving was that the company had chosen a different adviser’s read of its own sales cycle, which meant no plan the fractional CMO proposed could be adopted on its merits. The CFO’s later departure is not evidence that either party was right, only that the company and the CFO parted ways.
That makes the measurement window a question worth settling before signature rather than after. A company with a 6 to 18 month sales cycle that intends to judge marketing on quarterly return has set a test the marketing cannot pass, and whoever arrives next will fail it too. Three other situations also call for ending rather than narrowing: the real constraint is the product, the price, or the sales team, in which case no amount of marketing leadership reaches it; the budget that justified the engagement has gone and is not returning, which is common, since marketing is cut 45.4% of the time when executives cut expenses after a profit miss, per The CMO Survey’s 35th edition, fielded January 2026 among 308 marketing leaders at for-profit United States companies; or the company wants a different job done than the one it contracted for, which is covered in when a fractional CMO is the wrong hire. A serious B2B marketing leadership firm should be willing to name those out loud before taking the retainer.
Renew, narrow, or end: how the three options compare
The three options answer three different questions about a fractional CMO engagement: whether the numbers moved, whether the company wants part of the job back, and whether the company still trusts the judgment it hired. The table maps the signal to the decision so a chief executive can tell them apart before the review rather than during it.
| Signal you are seeing | Decision | What changes |
|---|---|---|
| Baseline KPIs moved, next problems still need senior judgment | Renew | New target for the next sprint |
| Numbers moved less than target, plan for next sprint is credible | Renew | Revised target, same scope |
| Marketing manager hired who can run team and vendors | Narrow | Strategy only, somewhat lower fee |
| Company follows another adviser’s marketing judgment | End | Engagement closes, handover documented |
| Measurement window shorter than the sales cycle, and fixed | End | Engagement closes rather than fails the test |
| Real constraint is product, price, or sales team | End | Engagement closes, constraint named |
Why do fractional CMOs stay in engagements too long?
Fractional CMOs overstay engagements for reasons that have little to do with money. Loyalty to a client and attachment to a marketing program that is working will both keep a marketing leader in a seat past the point their own rules say to leave. A buyer reading a firm’s decisive-sounding exit rules should know that the person writing them has broken them.
Peter Geisheker, founder of The Geisheker Group, Inc., names his own version: “My loyalty has made me stay longer than I should have with some clients. Also, not wanting to leave a marketing program that I built that was working.”
This matters to a company on the other side of the table for a practical reason. If a fractional CMO is capable of staying out of loyalty, then their continued presence is not by itself evidence that the engagement is still earning its fee. The company has to run the renewal test on its own numbers rather than reading the marketer’s willingness to stay as a signal. The scheduled gate exists for exactly that reason, and so does the written target it is judged against.
What should the contract say about ending the engagement?
A fractional CMO agreement should name the review date, the notice period, and what the company owns at the end, which in practice means a defined minimum term followed by roughly 30 days’ notice for most B2B engagements. The minimum term stops the audit and baselining phase from being wasted. The notice period makes the decision at each gate something that can actually be acted on.
Three provisions matter more than the notice number. The first is what transfers when the engagement ends: advertising accounts, analytics, conversion tracking, documentation, vendor relationships, and the written plan, each named explicitly rather than negotiated at the exit when the leverage has moved. The second is which tier of scope the fee covers, so that moving between strategy with management and strategy alone has an agreed consequence rather than becoming an argument. The third is the measurement window, stated against the company’s actual sales cycle length, which is the disagreement most likely to end an otherwise working engagement.
Frequently asked questions
How long should a fractional CMO engagement last?
A fractional CMO engagement should last as long as the company still needs senior marketing judgment rather than execution capacity, which for most B2B companies means several consecutive 90 day sprints rather than a fixed term. 42% of interim executive projects now run longer than six months and 16% extend beyond a year, per the 2026 Talent Lens Survey from the executive search firm Heidrick & Struggles, based on 3,810 independent executives surveyed in August 2025. There is no correct duration in the abstract.
What is the difference between narrowing and ending a fractional CMO engagement?
Narrowing keeps the same marketing leader and reduces the scope, typically from marketing strategy plus team and vendor management down to strategy alone, at a somewhat lower fee. Ending closes the engagement. Narrowing is the right answer when a company wants part of the job back, usually because it has hired a marketing manager who can run the team and the vendors. Ending is the right answer when the company no longer follows the marketing judgment it hired.
Does a fractional CMO do the execution work?
At The Geisheker Group, Inc., no. The engagement covers marketing strategy and management of the company’s marketing team and vendors, and execution stays with marketing employees, freelancers, and agencies. Peter Geisheker describes the role as the marketing General rather than a soldier on the ground. This is one of the widest variations between fractional CMO practitioners, so a company comparing firms should ask each one directly rather than assume.
How do I know if my fractional CMO is doing a good job?
Compare current cost per lead, sales qualified leads, and cost to acquire a customer against the baseline measured in the first 30 days of the engagement, and judge both against the target agreed with the chief executive at signature. Separately, ask the in-house team and the outside agencies whether project dates are being met, since delivery slips show up with the team before they show up in a monthly report.
When should I replace a fractional CMO with a full-time CMO?
Move to a full-time chief marketing officer when the marketing function needs more hours than judgment: a team large enough to manage daily, a settled channel mix, and a volume of work that no longer benefits from a senior part-time leader. The full-time role is not the more stable choice by default. Average CMO tenure in the S&P 500 is 4.1 years, per Spencer Stuart, January 2026, and 31% of S&P 500 companies have no chief marketing officer at all.
Can a fractional CMO engagement be paused rather than ended?
A pause is usually a narrowing with a different name, and naming it accurately is worth the trouble. A genuine pause makes sense when a company is between funding events or waiting on a product launch, and it should carry a defined restart date and a reduced advisory fee. An open-ended pause with no restart date is an ending nobody wanted to say out loud, and the cost of that ambiguity is that the handover never happens.
Why would a fractional CMO end an engagement the client wants to continue?
Because a marketing leader whose judgment the company no longer follows cannot do the job, and because a fractional CMO is running a business and will not keep an engagement that is no longer worth running. Peter Geisheker states both reasons plainly rather than treating them as private. A company should expect that disclosed interest from any serious firm and read its absence as the warning sign.
What should I get at the end of a fractional CMO engagement?
A B2B company should receive full ownership and access to its advertising accounts, analytics, conversion tracking, and marketing stack, the written growth plan and budget, documented vendor and agency relationships, and the measured KPI history from the baseline onward. Name these in the agreement at signature rather than at the exit.
Installing this in your company
Understanding the renew, narrow, or end decision is straightforward. Installing it is harder, because it needs four things most companies skip at the start: a measured baseline, a written target agreed with the chief executive, a review date in the calendar, and a measurement window set against the company’s real sales cycle length. Without those, the renewal conversation becomes a referendum on whether people like each other, and that conversation has no right answer.
Putting them in place is fractional CMO work in its own right. It means auditing what is actually measurable today, agreeing a target that is ambitious rather than fantastical, writing the next 90 days down as a sequence with deadlines and owners, and settling decision rights so the plan is not waiting on an approval that never comes.
Honest disqualification: if the constraint on growth is the product, the price, or the sales team, a fractional CMO is the wrong purchase and The Geisheker Group, Inc. will say so rather than take the retainer. If the company intends to judge a 6 to 18 month sales cycle on quarterly return, settle that before hiring anyone, because no marketing leader passes that test. If marketing leadership genuinely is the gap, a 30 minute conversation is enough to tell. Book a call with The Geisheker Group, Inc. and bring your current numbers.
