The fractional leader should own priorities, briefs and performance decisions; the agency should own the scoped production it is hired to deliver. The founder approves business tradeoffs and claims that require company authority. Agree on shared measures, access and escalation before work starts.
Avoid two competing strategy owners
An agency is usually paid to perform a defined service: paid media, content, SEO or creative production. A fractional leader should decide whether that service is still the right priority and make the tradeoffs across channels. If both parties can change positioning, budget and goals independently, the founder will inherit every conflict. Write a responsibility map before the next brief.
Use one shared operating brief
The brief should name the buyer, buying moment, offer, proof, constraints, success measure and owner of approvals. Give the agency access to the evidence it needs and give the fractional leader access to agency working files and spend. The agency brief guide can help structure the document. Keep one source of truth so the landing page and ads do not tell different stories.
Review decisions, not just agency activity
At each review, ask what the agency shipped, what changed in the buyer or pipeline signal, what was learned and what the leader is deciding next. A good agency report can still hide a business problem if it focuses on clicks while qualified revenue is flat. Agree who can pause a test or reallocate spend and when the founder must approve it.
A bounded example
Imagine a paid-search agency delivering cheaper leads while sales rejects more of them. The agency can inspect keyword intent and landing pages; the fractional leader should decide whether the channel, qualification and offer still match the ICP. Sales must provide rejection reasons. Without that three-way loop, “good performance” and “bad pipeline” can both be reported accurately while the underlying decision remains unmade.
A responsibility map for the next campaign
Pick a live campaign and assign one owner for each of five decisions: target buyer and offer, channel strategy, asset production, budget changes and evaluation. The founder may approve the total risk; the fractional CMO may decide the message and whether the test continues; the agency may build ads and pages within the brief. Sales must define what makes an enquiry useful. Write the assignment in the campaign brief rather than relying on informal hierarchy.
Then set an escalation rule. If the agency sees weak click-through, it can adjust creative inside agreed limits. If leads arrive but sales says they are unqualified, the leader should inspect targeting and the fit rule with sales before approving more spend. If the offer itself is wrong, the founder and product owner may need to change the proposition. Review the campaign at a date chosen before launch. This keeps the agency from being judged only on platform metrics and the leader from claiming authority without responsibility.
Frequently asked questions
Should the agency report to the fractional CMO?
Often that works when the leader has authority over priorities and review. The founder should still know the contract, budget and escalation path.
Can the agency own strategy instead?
An agency can advise on its specialist channel, but company-wide tradeoffs across product, sales, budget and team need an owner with the right access and authority.
Are your agency and marketing lead pointing at each other when results stall?
Bring the agency scope, report and current priorities. We can establish who decides, who builds and what evidence triggers a change.
