Fractional CMO or marketing agency: which do you need?

Find the missing responsibility

You have an agency. The posts go out, the campaigns run and the monthly presentation looks organised. Yet you are still deciding the audience, rewriting the message and explaining what matters commercially.

That situation does not automatically mean the agency is weak. It may mean you bought delivery while leaving marketing leadership unfilled.

The reverse happens too. A founder hires a senior adviser, receives a sound plan and discovers there is nobody available to implement it. The advice may be useful, but the operational gap remains.

Choose by the missing responsibility rather than the more impressive title.

What an agency is usually equipped to provide

An agency can provide specialist capability and delivery capacity: media buying, creative production, content, design, development or search work. Its strength should match the job you need done.

Some agencies also do excellent strategy work. Ask which decisions they will own, how deeply they will research your customers and how that strategy will interact with sales and product. Do not assume either strategic depth or its absence from the word agency.

The commercial agreement matters. If the contract pays for a set number of assets, those assets will naturally become a major focus. You still need to define what they are intended to achieve.

What a fractional CMO adds

A fractional CMO works across the function. They may decide that the next improvement should happen in positioning, sales enablement or onboarding rather than in the channel the agency manages.

That requires a broader mandate than optimising one account. It also requires access: customer conversations, deal history, product constraints, budget and the people doing the work.

For example, a paid-media team can improve the quality of traffic sent to a trial. It cannot independently resolve a product integration that prevents customers from activating. Someone needs to connect the evidence and coordinate the response.

Three common situations

• Clear strategy, insufficient delivery: choose the specialist or agency that can execute the defined work. Judge relevant work quality, capacity and the feedback process.
• Plenty of activity, unclear direction: establish senior ownership of the target customer, priorities and measurement. A fractional CMO or strategic adviser may fill that gap.
• No strategy and no team: budget for both diagnosis and implementation. Hiring one side while ignoring the other leaves the work stuck.

There is a fourth possibility: the product does not reliably solve the customer's problem. Neither arrangement can promise to solve that through promotion. The useful marketing contribution is to surface the evidence early and help the company make an informed decision.

Put the division of work on one page

Before hiring, create a responsibility map covering customer research, positioning, channel selection, creative, campaign operation, website changes, reporting and approval.

For each item, name the person who decides, the person who produces the work and the person who approves exceptions. One person can appear in multiple places. The point is to remove ambiguity.

Then walk through a realistic scenario: lead volume rises but sales acceptance falls. Who investigates? Who can pause spend? Who speaks to sales? Who changes the brief? How quickly can the team act?

If every answer is still the founder, the proposed arrangement has not yet solved founder dependence.

Compare the full cost of the arrangement

An agency retainer and a fractional CMO fee are not interchangeable prices for the same output. Compare the entire system needed to do the work: leadership, specialist delivery, media, tools and your own time.

Avoid choosing an apparently cheaper setup that leaves a critical responsibility unowned. Equally, do not pay for ongoing leadership when a bounded specialist assignment would solve the actual problem.

First 10's Strategic Direction engagement is designed for founders who already have a team or agency and need senior direction. The embedded Fractional CMO option takes broader responsibility for the function. Start with the job that needs doing, and make the arrangement fit it.

Apply this to your business

Take one delayed campaign and identify whether it lacked a strategic decision, a capable producer, or both. Buy the missing responsibility before buying a job title.
