Agencies sell senior people in the pitch, then staff juniors on the work. They bill for hours but optimize for margin. They take on more clients than they can serve well because utilization is how they stay alive.
This isn’t every agency. But it’s enough of them that you should assume it until proven otherwise.
The pitch team vs. the delivery team
When you meet an agency, you’re meeting their best people. Partners. Directors. Senior strategists. These are the people who know how to close deals.
After you sign, those people disappear. They’re pitching the next client. Your account gets handed to coordinators, junior strategists, and account managers who weren’t in the room when the deal was made.
This isn’t a secret. It’s the model.
The question is: who will actually be doing the work? Ask. Get names. Look them up on LinkedIn. If you can’t meet them before signing, that tells you something.
Why agencies overcommit
Agency economics run on utilization. If a strategist can handle 4 clients but only has 2, that’s 50% utilization. The agency is losing money on that person.
The pressure is always to add clients. One more. Then one more. Until every person is at 100%+ utilization and nobody has time to think deeply about any single account.
When your agency seems stretched, they probably are. When they’re slow to respond, it’s not because they don’t care. It’s because they’re servicing more clients than they have capacity for.
This is how agencies die slowly: overpromising, underdelivering, losing clients, desperately pitching new ones to fill the gap. Repeat.
The margin math
Here’s how agency pricing typically works:
They estimate how many hours your account needs. They multiply by their blended rate (usually $150-250/hour depending on the agency). That’s your retainer.
But the blended rate isn’t what they pay people. A $200/hour blended rate might break down as:
- 10 hours of senior time at $300/hour cost: $3,000
- 30 hours of junior time at $75/hour cost: $2,250
- Total cost: $5,250 for 40 hours billed at $8,000
The margin is in the mix. More junior hours, more profit.
None of this is inherently wrong. But when you understand it, you ask better questions. What’s the actual breakdown of who’s working on my account? What seniority level is doing the strategic thinking vs. the execution?
The utilization trap
Agencies measure success by billable hours and revenue per employee. This creates perverse incentives:
- A project that should take 20 hours gets scoped at 30 (cushion)
- A simple task that a senior could do in 1 hour gets delegated to a junior who takes 4
- Problems that could be solved with a 15-minute conversation become elaborate processes
The goal isn’t to finish your work. It’s to fill hours while staying within scope.
I’m not saying people are consciously sandbagging. The system creates these behaviors. When utilization is how agencies measure health, everything bends toward filling time.
What good agencies do differently
Some agencies fight against this:
They’re honest about capacity. They’ll tell you when they’re too busy to take on new work. This seems bad for them but builds trust.
They introduce the actual team upfront. You meet the people who’ll do the work before you sign. If they’re not impressive, you know.
They price based on value, not hours. Project-based or outcome-based pricing means they’re incentivized to finish efficiently, not fill time.
They have lower client-to-team ratios. Fewer clients per person means more attention on each. Ask about this directly.
They can articulate when you shouldn’t hire them. An agency that says “we’re not right for everyone” and can explain who they’re wrong for is being honest about their limitations.
How to spot the difference before you sign
Questions to ask:
-
Who specifically will work on my account? Names and titles. Not “our team includes…”
-
How many other clients does that person manage? More than 5-6 is a warning sign for strategic roles.
-
What happens if [key person] leaves? How they handle continuity reveals how dependent they are on individuals.
-
Can you show me the breakdown of hours by role? Where the hours go tells you what you’re actually buying.
-
What’s your utilization target? If they don’t know or won’t say, they’re not thinking about this honestly.
When the model works anyway
Despite all this, agencies can be the right choice when:
- You need to move faster than you can hire
- You need specialized skills for a defined period
- You want to test channels before building internal teams
- You genuinely need scale and have clear metrics
The key is going in with open eyes. Understanding the model doesn’t mean avoiding agencies. It means structuring engagements to get what you actually need.
Know who’s doing the work. Define clear deliverables. Set milestones. Measure outcomes, not hours.
The model is broken. But you can still make it work if you know the game.
