A fractional CMO is a part-time senior marketing leader. For ecommerce brands, published retainers usually run from about $5,000 to $15,000 a month or more. Growth Copilot covers the part of that job most lean DTC brands need first: reading Shopify, ad, Amazon and email data as one business, deciding what matters, setting priorities and briefing the agency and team. It doesn't hire your team or run campaigns, which is why it starts from $2,500 a month.
Signs you need a fractional CMO, not another tool
- You're the founder and the acting CMO, and the weekly numbers review keeps slipping.
- Your agency reports platform ROAS. Nobody reports new-customer profit or cohort payback.
- Budget, launch and promo decisions get made without a view of which customers they create.
- Shopify, Meta, Google and Klaviyo each claim the same sale, so nobody trusts the totals.
- You've outgrown gut feel, but a $175k+ full-time hire isn't realistic yet.
Full-time CMO vs fractional CMO vs Growth Copilot

| Time to first decision | 3 to 6 months to hire, then ramp-up | A few weeks of onboarding | Days after read-only access is set up |
| Where the numbers come from | Whatever the team and tools report | Mostly agency and platform reports | Shopify, Meta, Google, TikTok, Amazon and Klaviyo, reconciled to your store's orders |
| How your agency is judged | Depends on the hire | Often platform ROAS and CPA | New-customer ROAS, contribution margin and cohort payback |
| Hires the team, runs creative | Yes | Often | No. Your agency and team execute; we brief them and score results |

A month with Growth Copilot
- Weekly signal briefWhat moved, why, and whether it needs a call this week. For example: new-customer ROAS on Meta fell while blended ROAS held, because returning buyers were hiding it.
- Monthly deep diveOne question answered properly: a product, channel, cohort or offer. For example: should the bundle replace the hero SKU as the lead ad product?
- Agency and team briefThe month's priorities and the scorecard to judge them by, such as new customer ROAS and cohort payback instead of blended ROAS.
- Decision supportA second read before budget shifts, launches, pricing, a promo calendar or an agency change.
Fractional CMO vs marketing agency vs consultant
| Marketing agency | One-off consultant | Growth Copilot | |
|---|---|---|---|
| Main job | Run channels: ads, email, creative | Answer one question or build one plan | Decide where growth comes from, every month |
| Sees | Mostly the channels it runs | What you share for the project | Every connected tool, read as one business |
| Paid by | Retainer or % of ad spend | Project fee | Flat monthly fee, not tied to spend |
| Conflict to watch | Grading its own work | Plan with no follow-through | None on spend: no media budget to protect |
Most brands need an agency or freelancer to execute. Growth Copilot sits above them, so the agency gets a clearer brief and a fair scorecard.

Questions founders ask
How much does a fractional CMO cost for an ecommerce brand?
Published retainers for ecommerce and DTC brands usually run from about $5,000 to $15,000 a month, and more for larger brands, depending on hours and scope. Growth Copilot starts from $2,500 a month because it covers data and decisions rather than team management or execution.
Is Growth Copilot a full fractional CMO?
No. It covers the data and decisions part of a CMO's job. Team building, brand direction and execution stay with you, your agency and your team, with our guidance.
Fractional CMO or marketing agency: which do I need?
Usually both jobs need doing. An agency runs channels. A fractional CMO decides where the budget should go and judges the agency's results. If your agency is the only one reading the numbers, it is grading its own work.
When should a DTC brand hire a full-time CMO?
When you need someone to build and manage a marketing team full time and the salary, bonus and equity make sense for your stage. Before that, many brands get more from senior decisions on a part-time or monthly basis.
Do I need to buy the Snapshot first?
Most founders do, so both sides see the data before committing. It isn't required. Get in touch and we'll talk it through.
Does it replace my agency?
No. Your agency keeps running campaigns. Growth Copilot gives them clearer priorities and a fair set of numbers to be judged on.
Do you need admin access to my accounts?
No. Read-only access or exports in our template. Access is removed when the work ends.
