The people who win your business are rarely the people who do your work. That gap is normal and not dishonest, but it is the single biggest predictor of how the next twelve months will feel. Ask for names, seniority, and hours before you sign, and ask what happens when the person assigned to you leaves.
A G2 reviewer describing a different agency captured the failure exactly: "constantly changing project managers and the issues with communication made it difficult to work with them." Notice what is absent from that sentence. No complaint about skill, strategy, or results. The work may well have been fine. The relationship still failed, on continuity alone.
Why does the pitch team disappear after the sale?
Because winning work and doing work are different jobs, and most firms staff them separately.
The people in the room during the pitch are usually senior — a founder, a strategy lead, someone who can answer anything. Their job is to win. Once the contract is signed, they move to the next pitch, because that is what they are paid to do. Your account passes to a delivery team, which is often more junior, and to an account manager who becomes your entire view of the work.
None of that is a scam. It is how the economics of a service business work. The problem is that nobody says it out loud, so you keep expecting the person who impressed you and keep getting someone else.
The version that actually costs you money is seniority dilution — the senior person is on your account for two hours a month, the rest is executed by someone learning on your budget, and the gap shows up in the work about four months in.
What does account manager turnover actually cost?
Every change resets context, and context is most of the value.
A new account manager does not know that you tried that channel in 2024 and it failed, that your best customers come from referrals, or that your busy season starts in March. You explain it again. Then you explain it again. Each reset costs you hours you do not invoice anyone for, and it costs the work its memory.
This is the same hidden cost that shows up when several vendors each hold a piece of the picture — industry vendor-management research puts the coordination overhead alone at 8–15% of annual vendor spend, none of which appears on a bill. We put real numbers to that in what using multiple marketing vendors actually costs.
Two changes in a year is a warning. Three is a pattern, and the pattern is usually about their business rather than yours.
What should you ask before signing?
Six questions. They are uncomfortable to ask and very easy to answer if the answer is good.
- Name the people who will work on my account, and their titles.
- How many hours a month does each of them spend on it?
- Which of them was in this room today?
- What is your average account manager tenure?
- If my account manager leaves, who takes over, and how is context handed across?
- Who do I call when something is wrong and the account manager is not fixing it?
Question three is the sharpest one. A firm that staffs honestly will tell you plainly that the strategy lead is on your account four hours a month and the rest is delivered by named colleagues. That is a fine answer. An evasive answer to a question this simple is the finding.
Question five matters more than people expect. Turnover happens everywhere. What separates firms is whether they planned for it.
These belong alongside the rest of your pre-signature checks, which we set out in how to evaluate a marketing agency before you sign.
How do you tell continuity from churn while it is happening?
Watch who answers, not how fast.
Healthy: the same names recur month to month, someone references a decision from six months ago without being reminded, and a person who is not your account manager occasionally appears because they actually touched the work.
Unhealthy: your only contact is a coordinator who relays questions to people you never meet, answers arrive a day later because they had to ask, and each new person opens with a discovery call about things you have already explained.
That second pattern is worth catching early — it belongs on the list in marketing agency red flags, and left alone it ends where these usually end, which we covered in when to fire your marketing agency.
What does the right structure look like?
Fewer people, named, who own the result rather than a task list.
The structural fix is not "demand senior people on everything" — that is neither affordable nor necessary. It is that someone senior owns your outcome and stays attached to it, while the execution around them can change without the account losing its memory.
That is the real difference between buying a scope and buying an owned result, and it changes what turnover costs you. When a firm owns the number, continuity is their problem to solve rather than yours to absorb. We wrote about that shift in what changes when an agency owns the outcome.
The short version
Ask for names and hours before you sign. Ask who in the pitch will still be there in month six. Ask what happens when your contact leaves, because eventually they will.
Skill is easy to assess and easy to find. Continuity is neither, and it is the thing that quietly decides whether a year of work compounds or restarts every quarter.
