When the Rainmaker Walked Out

What happened

A profitable business-to-business services firm came to market with one veteran salesperson bringing in roughly 70% of new business. The buyer paid a full multiple for the revenue and agreed no retention deal with that salesperson. Two months after closing she resigned, loyal to the departing owner and courted by a competitor. New business collapsed within the year, and the profitable firm the buyer thought he had bought was worth a fraction of the price.

The case, start to finish

The buyer’s error was not buying a concentrated firm. It was buying one at the price of an unconcentrated one.

A firm that was really a person

This is an anonymized composite, not a company you can look up. It is assembled from documented key-person patterns, and the arithmetic in it is the arithmetic that turns up whenever a services firm’s value sits inside one head.

The business on offer was a profitable B2B services firm, and nothing about it looked fragile. Revenue was real, the margins held, the client list had substance. What the file also said, in a line that was easy to read past, was that one veteran salesperson originated roughly 70% of new business. He had been there a long time. He knew the owner. He knew the clients.

That single number is the whole case, and the reason it did not stop the deal is that it did not present as a defect. It presented as competence.

The seller says the team is loyal

Sit on the buyer’s side of the table before the answer is known. You have financial statements you have checked and they are honest. Profit is profit. You have spent months looking and this is the first target that has cleared. Asked directly about the salesperson, the seller says what sellers say: the team is loyal, everyone is staying, it is a good place to work.

The tempting move is to accept that and pay the asking price, and the temptation is not stupidity. Every small services firm carries concentration risk of one kind or another, and a buyer who refuses all of it buys nothing. So this buyer did the natural thing and treated the revenue as though it belonged to the business. It appeared on the business’s income statement, under the business’s name, in an account the business owned.

It did not belong to the business. It belonged to a man with a phone.

Month two

The salesperson resigned two months after closing. His loyalty had been to the departing owner rather than to the entity, and a competitor had been courting him. That is the part the buyer could not see from outside and could have priced anyway: a rainmaker whose relationship runs to the person leaving has no particular reason to stay.

Within a year new business had collapsed, and the profitable firm the buyer had paid a full multiple for was worth a fraction of the price. Nothing operational had broken. The delivery team still delivered, the systems still worked, the reputation was intact. The engine that filled the pipeline had simply gone somewhere else, and 70% of new business is not a gap that effort covers.

The discount, and what the discount buys

The mechanism underneath is that key-person risk is a pricing problem rather than a disqualifying one. Valuation practice puts the typical key-person discount at roughly 5 to 25%, wider for very small firms, and that range exists precisely because concentrated firms sell all the time.

The tools were all ordinary and all available. A retention package gives the salesperson a reason to stay that survives the old owner leaving. A non-compete and a non-solicit stop the competitor’s approach from being free. An earnout moves part of the price into the future so the seller shares the loss if the book does not travel. Any one of them would have changed the shape of that year.

The buyer’s error was not buying a concentrated firm. It was buying one at the price of an unconcentrated one.

If you are buying something smaller

The transferable version is a question rather than a formula: what happens to revenue if this person gives notice on the day you close? Ask it about each name, and ask it before you have decided you want the deal, because after that the answer you were hoping for starts arriving on its own.

Then price the answer. Discount it, structure around it, or both. And notice where the line sits. Refusing every business with a key person in it means refusing most good small services firms, which is not caution. It is a different mistake with a better reputation.

Timeline

• Before A profitable B2B services firm is for sale; one veteran salesperson brings in ~70% of new business.
• The deal Buyer pays a full multiple, charmed by the revenue, with no retention agreement for the key salesperson.
• Month 2 The salesperson, loyal to the departing owner and courted by a competitor, resigns.
• Year 1 New business collapses; the "profitable" firm the buyer bought is worth a fraction of what they paid.

You're in the owner's chair

Diligence shows one veteran salesperson originates ~70% of the target’s new business. The seller insists “the team is loyal.” The price assumes the revenue continues. What do you do?

• Pay the full asking price — profitable is profitable, after all
• Walk away — key-person risk is uninsurable
• Condition the deal: retention package, non-compete, earnout

Business model

A relationship-driven services firm whose real asset was the personal book of one rainmaker, not systems, brand, or contracts.

Revenue model

Project fees and retainers won overwhelmingly through one person's relationships, so the revenue and the individual were inseparable.

Cost structure

Payroll-heavy. The hidden risk: the highest-value "asset" (the salesperson) could leave at will, taking the revenue engine.

Strategic challenge

The value was concentrated in a person who could walk out the door, the classic key-person risk, and the buyer treated the revenue as if it belonged to the business.

Key decision

The fatal one: paying a full price with no retention deal, non-compete, or earnout tied to the key employee staying. The business was a person wearing a company's name.

What worked

Nothing structural. The numbers were real, but they weren't transferable, and the buyer never tested transferability.

What failed

Diligence and structure: no assessment of how dependent the revenue was on one person, and no mechanism (retention bonus, non-compete, earnout) to hold that person or share the risk.

Risk factors

Employee/key-person concentration; loyalty to the departing owner; no retention agreements; revenue that leaves with an individual.

Lesson summary

Ask whether a business would survive if its key people walked out. When value rides on specific employees, discount for it and lock it in with retention agreements, non-competes, and earnouts. Otherwise you may be buying a person, not a business.
