Fractional CMO
Fractional CMO
for Ecommerce Brands
A fractional CMO owns your marketing the way a full‑time one would — the strategy, the budget, the channels and the people doing the work — for a few days a month instead of a salary. I do it for direct‑to‑consumer brands on Shopify, and I have run the job for a company I owned.
The Definition
What a Fractional CMO
Actually Is
A fractional CMO is a senior marketing leader who takes ownership of your whole marketing function on a part‑time, ongoing basis. Not a project. Not advice. Ownership — of the plan, the budget, the channel mix and the people delivering it.
The word that matters is ownership. A consultant recommends. An agency executes a brief. A freelancer completes tasks. A CMO decides what happens, spends the budget, and is accountable for what it returns.
It is not a consultant
A consultant hands you a strategy and leaves you to run it. A fractional CMO runs it.
It is not an agency
An agency delivers a service you brief them on. A fractional CMO writes the brief and decides whether the agency is worth keeping.
It is not a freelancer
A freelancer owns a task. A fractional CMO owns the number the tasks are meant to move.
The Remit
Six Things
a CMO Owns
A marketing manager runs channels. A CMO decides which channels deserve to exist, and what everything else is costing you by comparison.
Strategy and budget
Where the money goes each quarter, and what each channel has to return to keep its share.
Paid acquisition
Google, Meta, Amazon and Microsoft. Built and run, not outsourced and hoped for.
Email and retention
Flows, segmentation and the repeat purchase rate that decides what you can afford to pay for a customer.
SEO and content
The channel that costs more up front and less forever, which is why it never gets started.
Site and conversion
The product page and the checkout. The cheapest growth available is usually already on your site.
Vendors and contractors
Sourcing them, briefing them, managing them, and firing them when the work does not land.
Readiness
Signals You Are
Ready for One
Most brands that ask me about this are not ready, and I say so. It has become a fashionable answer to a real problem.
You are ready if
- You are doing $2M–$20M a year and growth has flattened
- Ad spend is past $20,000 a month and nobody owns the number
- You have three or four freelancers and no one coordinating them
- You, the founder, are still approving ad copy at 11pm
- You know the channels are underperforming but not which one to fix first
You are not ready if
- You are under $1M a year — you need an operator, not a strategist
- You have no product-market fit. Marketing leadership will not manufacture demand
- You want someone to run one channel. That is cheaper as channel management
- You want a plan to hand to someone else. That is a consulting engagement
The Cost
What Marketing Leadership
Actually Costs
Three ways to get senior marketing thinking into an ecommerce business. The right one depends almost entirely on your revenue.
Full-time hire
$10,000–13,000
per month, fully loaded
Salary, payroll tax, benefits and equipment for one senior marketing lead — before you count anyone working under them. Two to three months to hire, and the knowledge leaves when they do.
This page
Fractional CMO
From $7,000
per month
The same ownership, a few days a month, starting in days rather than months. No payroll, no notice period, and you can stop when the function is built.
Agency retainer
$8,000+
per month
A full-service retainer covering strategy and execution across channels — the scope this page is actually comparable to. Strong at production volume; nobody there is accountable for your P&L, and below a certain spend you will not get their senior people.
Figures for the full-time and agency columns are typical market ranges, not quotes. My own pricing is published in full below.
The First 90 Days
What Actually
Happens
No 94-slide strategy deck. The deliverable is a marketing function that works when you are not watching it.
Days 1–30
Find out what is true
Every account, the analytics, the email programme, the site. I come back with what is actually wrong and what it is costing you, in writing, ranked. Most of this month is reading, not changing.
Days 31–60
Fix the foundation
Tracking, feed health, account structure, the worst of the site leaks. Unglamorous work that decides whether anything built later can be measured at all.
Days 61–90
Build the engine
Channel mix set against a budget, creative in production, email flows live, and a reporting rhythm you can read in five minutes. By day 90 you should know what each channel returns.
Operator Experience
I Have Held
the Seat
Most fractional CMOs have only ever advised. I co-founded ModernReform, a high‑ticket direct‑to‑consumer fitness equipment brand, and ran its entire marketing function — the site, the branding, the ad accounts, the vendor relationships. We took it to $2.5 million in annual sales in 2021 and sold the business through Flippa in 2024 for a seven-figure sum.
That is the difference between someone who can describe the job and someone who has done it with their own money at stake. More on that here.
The Choice
Fractional, Full‑Time
Or An Agency
Three ways to get senior marketing leadership, and the honest version of when each one is right. I am one of them, and I am not the answer for everyone.
| Fractional CMO | Full-time CMO | Agency | |
|---|---|---|---|
| Time to start | Weeks | A months-long search | Weeks |
| Cost | A monthly fee, cancellable | Salary, equity and the cost of a bad hire | A monthly retainer, often tied to spend |
| Who does the work | The person you hired | The person you hired, plus the team they build | Usually not the person who sold it to you |
| Depth of attention | A few days a month, shared with other clients | All of it — nobody beats this | Varies by account size |
| Bench and capacity | One person’s hours | A team they can hire | Strongest here — specialists on tap |
| Best when | Decisions are the bottleneck, not hours | Marketing is the core of the business and needs an owner | You need volume of execution more than judgement |
If you already have a capable head of marketing, you want a specialist, not this. And if marketing is the engine of the whole company, hire someone full time — a few days a month is not enough to own something that important.
