You don’t hire an agency. You hire whoever still works there this month.

The pitch is always the same.
Senior people. “A team”. “Specialists”. “We’ve done this before.”

Then the project starts and you meet your real agency.
A junior account manager, a rotating cast of channel kids, and one person who seems to have been awake since 2019.

And every month looks identical.

New faces on the call.
New questions you answered in week one.
New “quick audit” because the last person “rolled off”.
New learning curve, paid for entirely by you.

It’s the perfect model for them.
They sell expertise and deliver onboarding.
They call it “resourcing”.
You call it “why do we feel like we’re constantly starting over?”

The cost isn’t just the churn.
It’s the lag.

A good operator spends months learning what actually drives demand in your business.
Your seasonality.
Your call center reality.
Your sales team habits.
What offers work.
What breaks conversion.
What actually matters in the P&L.

If the agency can’t keep the same people long enough to learn your business, they’re not managing marketing.
They’re running a graduate scheme funded by your budget.

If you want a simple test:

Ask them to name the last three changes they made that improved revenue, not “performance”.
If the answer starts with “we’re still gathering insights”, you’ve hired a carousel.
