The short answer: choose a fractional CMO who
- has led marketing at a company like yours (stage, sales cycle, buyer);
- starts with positioning, not channels;
- builds systems your team can run without them;
- commits to a written 90-day plan;
- sets targets only after measuring your baseline;
- defines scope, hours and who does what;
- will tell you things you don’t want to hear;
- leaves you owning every plan, playbook and report.
Test each one with the questions below, then start with a clearly scoped first phase before committing to more.
I’m a fractional CMO, so I’ve sat on the other side of this decision many times. The companies that hire well aren’t the ones with the biggest budgets. They’re the ones that know what to test for. This guide is what I’d tell a friend who was about to hire someone like me.
What is a fractional CMO?
A fractional CMO is an experienced chief marketing officer who leads your marketing part-time, usually on a monthly retainer instead of a full-time salary. They set the positioning and the plan, direct your team and agencies against it, build the reporting, and are accountable for results. You get executive judgment without the cost of a full-time executive.
Do you actually need one?
A fractional CMO is usually the right fit when marketing has become too important for a founder or partner to run on the side, but a full-time CMO isn’t justified yet. Common signs:
- Good ideas stall because nobody senior has the time to run them.
- Agencies and freelancers are busy, but nobody is coordinating them against your priorities.
- Leads arrive without a source, so nobody can say what marketing is worth.
- Ask three people what you do and you get three different answers.
- You’re hiring salespeople and have no playbook to train them on.
If you only need execution, such as ads, design or social media, a specialist or agency may be enough. If you need someone to decide what to do and own the outcome, you need a CMO.
The 8 criteria that matter
1. Experience with a business like yours
Industry matters less than you’d think. Business model matters more. A CMO who has sold long-cycle, high-trust services to business owners will adapt faster to your firm than one with a decade of consumer e-commerce, even in your industry. Look for overlap in sales cycle, deal size, buyer type and regulatory constraints.
2. Positioning before tactics
The most expensive mistake is a CMO who jumps straight to channels: “we’ll fix your SEO, launch LinkedIn ads and start a podcast.” Channels amplify a message. If the message is unclear, they amplify the confusion. A strong candidate wants to understand what category you can own and what problem you solve best before recommending a single tactic. (A quick way to check your own positioning is the Any-Three-People Test.)
3. An operator, not only an advisor
Advice is cheap. What you’re paying for is someone who can build the machinery: the plan, the lead tracking in your CRM, the reporting, the content calendar and the documented processes your people will run. Ask to see real examples of plans, dashboards or playbooks they’ve built (with client details removed).
4. A written 90-day plan
By the end of the first month, you should have positioning your leadership has signed off on and one marketing plan with owners and deadlines. By day 90, live campaigns, working attribution and a results package. A candidate who can’t describe their first 90 days in concrete terms won’t produce them either. Here’s what a good first 90 days looks like.
5. Honest measurement
Be wary of anyone who promises a revenue number before seeing your data. In businesses with long sales cycles, revenue from new marketing often won’t appear inside a quarter. A credible CMO measures a baseline first, then reports in tiers: foundations that move in weeks, funnel metrics like qualified leads and booked meetings, pipeline value, and closed revenue as deals land.
6. Clear scope, time and roles
“Fractional” can mean two days a month or four days a week. Get in writing how many hours or days you’re buying, what’s included, and who does what across your leadership, the CMO, your team and your agencies. Most friction in these engagements comes from unclear responsibilities, not bad marketing.
7. Candour
You’re hiring someone to tell you the truth about your marketing, including the parts that are your fault. Notice whether a candidate pushes back on anything in the interview. If they agree with everything you say, they’ll do the same with your ideas, including the bad ones.
8. You own everything
Plans, positioning, playbooks, SOPs, dashboards and content should belong to your company, and be documented well enough that someone else could pick them up. When the engagement ends, the knowledge should stay with you.
12 questions to ask, and what good answers sound like
| Ask | A good answer |
|---|---|
| What would you do in the first 30, 60 and 90 days? | Specific steps and deliverables, starting with an audit and positioning, not a list of channels. |
| How will we know it’s working? | Named metrics in tiers, and a plan to measure the baseline before setting targets. |
| What do you need from us? | Access to data, a decision-maker who can sign off quickly, and input from sales and customer-facing staff. |
| Who does the hands-on work? | A clear split between what they do personally, what your team does and what vendors do. |
| How do you work with our agencies? | They set priorities and deadlines and hold agencies to them, rather than replacing them by default. |
| Can you show me a plan or report you’ve built? | A real, anonymized example. Hesitation here is a warning sign. |
| Tell me about an engagement that didn’t go well. | An honest story with what they learned. “None” is not an honest answer. |
| How many clients do you carry at once? | A number that fits the hours you’re buying, and a clear answer on response times. |
| What would make you recommend we hire full-time instead? | They can describe the point where a full-time hire makes more sense, and would help you make it. |
| What happens to the work if we stop? | You keep everything, documented well enough to hand to someone else. |
| How is the engagement priced and structured? | A defined first phase with a fixed fee or retainer, then month to month or a short term. |
| What would you need to see to tell us we’re wrong? | Evidence from customers and data, and a willingness to say so directly. |
Red flags
- Guaranteed revenue numbers before they’ve seen your data.
- A channel-first pitch that skips positioning and strategy.
- Vague answers about who does the work, or a senior name on the proposal and juniors on the account.
- No examples of plans, reports or playbooks from past work.
- Long lock-in contracts before you’ve seen any results.
- They keep the intellectual property, or the plan lives only in their head.
- Agreeing with everything in the interview.
How much does a fractional CMO cost?
Pricing varies widely with hours, scope, industry and location. As one reference point, Go Fractional’s benchmarks from its U.S. marketplace show an average rate of about $180 an hour (most between $125 and $225), retainers starting around $11,000 a month, and an estimated typical retainer of $15,800 a month (Go Fractional). Expect lower figures for fewer hours or smaller scopes.
Two structures are most common: a monthly retainer for a set amount of time, and a fixed-fee first phase (often 90 days) with defined deliverables. The second is easier to evaluate, because you know exactly what you’re buying. Either way, the retainer should cover the CMO’s time; media spend and specialist production are usually separate and should be approved before they’re incurred.
Fractional CMO, full-time CMO or agency?
A full-time CMO makes sense when marketing needs a leader every day and you can support the salary, benefits and often equity. An agency is right when you know what to do and need production capacity. A fractional CMO fits in between: executive judgment and accountability, part-time, often directing the agencies you already have. There’s a side-by-side comparison on my services page.
A simple hiring process
- Write down the problem, not the job description: what isn’t working and what success looks like in a year.
- Shortlist two or three candidates with experience in a business model like yours. Referrals from founders in your network are the best source.
- Hold a discovery call with each. Use the questions above and notice who asks the sharper questions back.
- Ask for a written scope covering the first phase: deliverables, responsibilities, KPIs, time and price.
- Check references, and ask them what changed because this person was there.
- Start with the first phase, review it honestly at the end, then decide whether to continue.
Frequently asked questions
How do I choose a fractional CMO?
Choose a fractional CMO who has led marketing at a company like yours, starts with positioning before tactics, can build the systems your team will run (plans, tracking, playbooks), puts a 90-day plan in writing, sets targets only after measuring a baseline, defines scope and time clearly, and leaves you owning everything they create. Test those things with specific interview questions and a clearly scoped first phase.
What should I ask a fractional CMO before hiring them?
Ask what they would do in the first 30, 60 and 90 days; how they would measure success and what baseline they need first; who does the hands-on work; how they work with your agencies; how many clients they carry at once; and what you keep when the engagement ends. Strong candidates answer with specifics, not slogans.
How much does a fractional CMO cost?
Most fractional CMOs charge a monthly retainer. Go Fractional's U.S. marketplace benchmarks show an average of about $180 per hour, with retainers starting around $11,000 a month and an estimated typical retainer of $15,800 a month. Costs vary with hours, scope, industry and location, and many engagements begin with a fixed-fee first phase.
How long should a fractional CMO engagement last?
Start with a defined first phase, often 90 days, long enough to fix foundations and launch real campaigns. After that, continue on a monthly basis if the results justify it. Be cautious of long lock-in contracts before you have seen the work.
What are the red flags when hiring a fractional CMO?
Watch for promises of specific revenue before they have seen your data, a plan that starts with channels instead of positioning, vague answers about who does the work, no examples of plans or reports from past engagements, and contracts where they keep ownership of the plans and playbooks they build for you.
Is a fractional CMO better than a marketing agency?
They do different jobs. An agency executes. A fractional CMO decides what is worth executing, owns the plan, and holds everyone, agencies included, accountable to results. Many companies keep their agency and add a fractional CMO to direct it.
If you’re weighing whether a fractional CMO is right for your company, book a discovery call. You’ll get my honest read, even if the answer is that you don’t need one yet.
