Should you hire a marketing agency or a fractional CMO first?

Founders ask "should I hire a marketing agency?" when they feel behind. The better question is what is missing: hands, brain, or both.

Answer first

Hire an agency first when:

• You know the channel and the offer
• You can brief weekly and judge output
• You need execution volume (ads, creative production, email builds)

Hire a fractional CMO first when:

• Priorities across channels are unclear
• ROAS stories disagree with the P&L
• Multiple vendors need a single owner
• You are the bottleneck and specialists would still escalate to you

Hire neither until you can show contribution, CAC and a 90-day priority list on one page.

Side-by-side

Need	Agency	Fractional CMO
Media buying depth	Strong fit	Not the core product
Cross-channel priority setting	Weak unless scoped oddly	Strong fit
P&L ownership	Rare	Expected
Brand system + growth together	Varies wildly	Should be native
Speed to assets	Often strong	Depends on their network

More detail lives on fractional CMO vs agency.

A simple decision tree

1. Can you explain what must happen in the next 90 days in five bullets tied to contribution?
   • No: fractional (or audit) first
   • Yes: go to 2
2. Is the gap mostly capacity in a known channel?
   • Yes: agency or specialist
   • No: fractional or Head of Marketing path
3. Do you already have multiple vendors?
   • Yes: you need a client-side owner before more retainers

Cost framing (not a quote)

Agencies look cheaper per month until you count misdirected spend. Fractional leadership looks expensive until you count the budget it redirects or stops.

Model:

• Retainer
• Media they influence
• Internal time managing them
• Cost of a wrong priority for a quarter

If you already have an agency

Ask:

• Who sets priorities, them or you?
• Do reports include contribution and payback?
• What did they kill last month on purpose?

If answers are mushy, read firing framework before you renew.

Practical recommendation for €1M to €10M

Most brands in this band eventually need execution plus ownership. Sequence beats stacking random retainers. Ownership first if the plot is unclear. Execution first if the plot is clear and under-staffed.

I will not pretend every agency is waste or every fractional is a hero. Fit the seat to the bottleneck. Then hold them to the P&L.
