Advisory / Fractional CMO
A fractional CMO for startups, from founder-led sales to a motion someone else can run
You raised. The board wants a growth plan by the next meeting. Founder-led sales got you here and has quietly stopped scaling, and a full-time CMO is not a decision you can responsibly make on sixteen months of runway.
This is the alternative: one senior marketing consultant, part-time, AI-assisted, no agency layer between the decision and the work. I make the decisions your stage actually needs made, which is what you sell, who to, and which single channel should become repeatable, and I write them down so your first marketing hire inherits a plan instead of a blank page.
Positioning first. One channel second. Team last. That order is not a preference, it is what stops a startup spending runway on an experiment nobody can read.
No deck needed. Bring your last ten deals and your runway number.
I hold a small, fixed number of retained engagements at a time, because one person can only carry so many. Current availability and the next start date are confirmed on the call.
Where startups actually stall after the raise
Three stall points show up again and again in the twelve months after a seed or Series A round. They look like different problems and they are the same problem.
The founder-led sales ceiling
The pitch lives in one head. It changes shape depending on who is in the room and has never been written down, so the first AE you hire cannot reproduce it and neither can your website. Revenue stops tracking headcount.
Nobody owns the narrative
Three decks, two websites, and a pitch that changed after the round, all describing subtly different companies. Each is defensible alone. Together they teach a stranger nothing, and a stranger is who you now need to convince.
Activity without direction
A junior marketer or an agency is producing posts, ads, and a newsletter, and nobody holds a thesis about which is supposed to become the repeatable channel. Output is high. No decision is being tested.
All three are symptoms of the same gap, and it is not a doer gap. You have no shortage of people who can make things. You have a shortage of someone senior accountable for deciding which things are worth making, and willing to say out loud that two of your three current efforts should stop. That diagnosis is written up in the signs that you need a fractional CMO.
Positioning before channels
Here is the test the whole engagement starts from. Can a stranger who reads your homepage once repeat, without prompting, what you do and who it is for? Not agree with it. Not be impressed by it. Repeat it. Most pre-Series-A startups fail that test and have never been told, because everyone who reads the homepage internally already knows the answer.
The sentence gets validated in five to eight conversations with real buyers: recent wins, recent losses, and at least one account that left. Those conversations are run by the founder, not by me. I write the interview guide and do the pattern analysis afterwards, but the founder asks the questions, because at this stage the pattern has to end up in the founder's head rather than in a consultant's deck. That is honest, and it is part of why this engagement costs less than people expect.
The reason it comes first is mechanical, not aesthetic. A company that cannot state its promise in a repeatable sentence cannot judge whether a channel worked. If the message is unreadable, a channel test returns an unreadable result and you have spent a month of runway learning nothing. Channel work before positioning is an experiment with no control.
The output is a written ICP narrow enough to disqualify people, which is the point of one. How to define an ideal customer profile covers the format I use.
Pre-product-market-fit and post-raise are two different jobs
The most expensive mis-scope in startup marketing is buying the post-PMF engagement while you are still pre-PMF. The two jobs share a job title and almost nothing else.
Pre-product-market-fit
The job is usually subtractive
- Narrow the ICP until it feels uncomfortably small
- Rewrite the promise on the homepage so one sentence carries it
- Demand testing at deliberately small spend
- Interview churned accounts and lost deals, not just wins
- Frequently: stop spend and kill two of your three channels
If someone proposes building a demand-generation machine here, they are spending your runway on a hypothesis nobody has validated. The honest recommendation at this stage is often to stop spend, kill two of your three channels, and get the story right before anything is amplified.
Post-PMF and post-raise
The job flips to making it repeatable
- Codify the founder pitch into messaging other people can run
- Instrument the funnel so the next decision has evidence behind it
- Pick one channel and make it work before adding a second
- Define what the first marketing hire actually is, usually a doer
- Write the marketing section of the board update so it survives scrutiny
Here the constraint is transferability rather than truth. The pitch works, it just cannot leave the founder's mouth intact. The work is turning one person's intuition into something a new hire can execute in their second week.
The fork is not about company age or how much you raised. It is whether you have customers who renew, refer, or expand for reasons you can state in a sentence. If you cannot state the reason, you are pre-PMF whatever the round said, and the engagement should be scoped accordingly.
The real cost is runway, not retainer
Founders instinctively compare a fractional retainer against zero. The comparison that decides the outcome is against a wrong first marketing leader, and that one is best counted in months rather than dollars.
Two to three months to run the search. Three to ramp. Three more before anyone says out loud that it is not working, because saying it early is socially expensive and everyone involved wants it to work. Add a channel budget spent in the wrong direction while you wait. Call it six to nine months. On a sixteen-month clock that is most of what you have, and unlike cash it is the part you cannot raise more of.
A fractional engagement is reversible inside a normal notice period. That reversibility is not a discount on the service, it is the service.
What this costs
The $600 Visibility Starter and the $1,000 SMB Growth Plan are fixed-scope products with a written deliverable, a diagnostic and a strategy engagement respectively. They are not retainers and they do not come with a retained leader. Retained fractional leadership starts at the $3,000 Channel Growth level per month and is scoped individually above that. Enterprise engagements are quoted custom.
At startup stage the fixed-scope positioning diagnostic is often the right entry point: fixed fee, fixed output, no ongoing commitment.
Full tier detail on the pricing pageA hard qualifier, so nobody wastes a call: if you are pre-raise and $3,000 a month is not a number you can commit to without flinching, do not book a retained engagement. Buy the fixed-scope diagnostic, or come back after the round closes.
For the full breakdown of what moves the number, what a fractional CMO costs a startup goes through the pricing models one by one.
One channel, run properly for 90 days
The channel is chosen from three unfashionable inputs. Where your first five customers actually came from, rather than where you wish they had. What the founder can personally sustain for a quarter without resenting it. And what does not require a budget you do not have. That usually leaves one candidate, which is the point.
Running it properly means a weekly commitment that does not move when something urgent happens, a written hypothesis about who should respond and why, and evidence agreed in advance that ends the test in either direction. A channel test with no kill criterion is not a test, it is a habit with a budget line.
Weeks 1-2
Positioning audit, plus win and loss interviews on the founder's last ten deals.
Weeks 3-4
ICP and messaging written down in a form somebody other than the founder can use.
Weeks 5-8
Instrument what is not measured. Kill what is not working, in writing, with the reason attached.
Weeks 9-12
One channel test with a pre-agreed kill criterion, and the marketing section of the next board update.
That shape is deliberately shorter than the canonical version, because a startup quarter has fewer moving parts and less patience than a mid-market one. The full sequence lives on the first 90 days section of the fractional CMO hub.
The metrics I set with founders, and the ones I ignore
Startup measurement fails in a specific way: too many numbers, none of which change a decision. The list is short, and every entry earns its place by altering what happens next.
What gets set
- Time to first repeatable channel
- Pipeline created per month against the plan the raise was based on
- Cost per qualified conversation
- Share of pipeline that does not come from the founder's own network
The last one carries more weight than it looks. Pipeline that does not originate in the founder's own network is the best available proxy for whether the motion is transferable at all.
What gets ignored at this stage
- MQL counts
- Impressions and reach
- Follower growth
- Any attribution model pretending forty datapoints carry a signal
At startup volume most dashboards are noise wearing a chart. A founder who acts on noise makes a confident decision about nothing and pays for it in runway.
If the website is where those conversations begin once the founder is not in the room, it is usually the cheapest thing to fix first. The website conversion checklist covers it, and the website growth system is the scoped build if it needs more than a checklist.
When a startup should not hire a fractional CMO
You are pre-seed with no product in market and no distribution hypothesis. You need fifty customer conversations, not a CMO.
You need forty hours a week of hands-on execution. Hire a contractor or a generalist marketer. A part-time leader is the wrong shape for that job.
The founder does not actually want to hand over the story. A fractional CMO with no decision rights is an expensive note-taker.
You have under roughly six months of runway. Nothing structural pays back inside that window, and you should be selling rather than restructuring.
If two of these describe you, do not book a call yet.
The engagement
One person, and that person is me. No account manager, no junior team, no agency layer. That is the constraint, and it is also why the work is senior: whoever is in your weekly slot is whoever makes the decisions. Short cycles suit startups better than quarterly ceremony, so the rhythm is a standing weekly session, a monthly written review, and a decision log recording what was chosen and why, so the reasoning survives the engagement ending.
Hands-on execution is bounded and named up front rather than discovered in month two. Research, first drafts, variants, list building, monitoring, and reporting are AI-assisted. Positioning, pricing, claims, and channel decisions are not. Anything a customer reads as a promise is written by a person who can be held to it.
Deliverables are built for your next full-time hire to inherit rather than redo. If a document only makes sense while I am in the room, it has failed.
And the exit criterion, stated at the start: once there is product-market fit, one repeatable channel, and enough revenue to fund a real salary, the advantage moves in-house and a consultant becomes overhead. I will tell you when you reach that point. Naming the end of the relationship is more useful to you than any promise about its beginning.
Who you are actually hiring
Mustard Seed Solutions is one senior marketing consultant, based in Warsaw, Poland, with 20+ years in IT infrastructure presales and product marketing, working in English, Chinese, and Japanese.
Being straight about the fit: the case studies published on this site are established B2B technology vendors, not venture-backed startups. What transfers is the work itself, which is positioning, ICP definition, and go-to-market for technology companies. If startup-stage references matter to you, ask on the call and I will tell you exactly what exists and what does not.
Common questions
At what stage should a startup hire a fractional CMO?
Most usefully once there is a product in market and some revenue, typically around a seed or Series A raise, when founder-led sales has proven demand but cannot scale further. Before that point the work is customer discovery and positioning, which a founder generally should not delegate.
Can a fractional CMO help before product-market fit?
Yes, but the job is the opposite of what most people expect: narrowing the ICP, sharpening positioning, and cutting spend on channels testing a hypothesis nobody has validated. If someone proposes building a demand-generation engine before you have product-market fit, they are spending your runway on guesswork.
Consultant, agency, or a first marketing hire?
A consultant makes the decisions, an agency supplies execution capacity for a decision already made, and a first hire supplies continuity once there is something worth continuing. Most pre-Series-A startups buy them in exactly the wrong order.
Does a fractional CMO replace hiring a marketing team?
No. The point is to establish direction and a working motion first, so that when you do hire, you are hiring against a defined role instead of guessing. The first hire after a fractional engagement is usually an execution-focused generalist, not another leader.
How is this different from hiring a marketing agency?
An agency executes a channel. A fractional CMO decides which channels deserve budget and owns the outcome across all of them. For a startup that matters because the expensive mistake is rarely bad execution, it is well-executed work pointed at the wrong market.
What if we are bootstrapped rather than funded?
The same logic applies, but the constraint is cash rather than runway to the next raise, so engagements usually start narrower. Positioning and one channel, rather than a full marketing function, and a fixed-scope diagnostic is often the sensible first purchase.
What happens to the work if the engagement ends?
Everything is written down: positioning, ICP, messaging, the channel decisions and why they were made. The deliverables are designed for your next full-time hire to inherit, not to make you dependent on the consultant.
