How a founderâs most loyal client capped the companyâs exit multiple
Early Access Note
We just launched the first version of our business valuation dashboard and are testing it with a small group of founders. If you want to see how buyers evaluate valuations in real time, you can request a private walkthrough.

Today's issue covers one of the key inputs we built it around.
A StoryâŚ
Last week, I was on a call with a founder who sounded proud and uneasy at the same time.
I was on a call last week with a founder who sounded confident and uneasy at the same time.
âWeâve got a great client. Long relationship. About 45 percent of our revenue.â
Then he added, almost under his breath,
âI know buyers donât love that.â
He was right.
And it had nothing to do with loyalty or performance.

Hereâs what founders miss about client concentration.
Buyers don't ask, "Is this client loyal?" They ask, "What happens if they leave?"
And then they price the answer in.
I've watched buyers do this in real time. They haircut projected cash flow. They lower the multiple. They add earnouts or holdbacks. Or they walk entirely.
Not because the business is bad. Because too much value walks out the door with one relationship.
The founder still sees a strong company. The buyer sees fragile cash flow.
Those are two very different valuations.
Client concentration changes how buyers underwrite risk.
When one client is too large, buyers assume revenue is not durable, pricing power is limited, transition risk is high, and the founder is more embedded than they admit.
That shows up directly in the offer.
Same business. Same EBITDA. Lower multiple.
Why? Because buyers pay for what survives without you and without any single customer.
Concentration isn't a red flag. It's a math problem.
And math always wins in an exit.
If youâre thinking about an exit someday, do this now:
Stress test your largest client.
Ask yourself, "If they left tomorrow, what multiple would a buyer apply?"
Translate concentration into dollars.
Rough rule of thumb: every client over 20% costs you leverage in negotiations. That leverage shows up as lower price, worse terms, or both.
Prove replaceability.
Build evidence that revenue is repeatable elsewhere. Proof means contracts, pricing consistency, and diversified pipelines.
You don't need to fire your biggest client.
You need to show the business doesn't depend on them.
