The Growth Engine You Bought Was the Founder

The deal model had a slope on the growth line. Retention was strong, most of the revenue repeated every month, and the founder agreed to stay two years, so the slope looked safe. Two years later the add-on acquisitions are carrying the number and the company on its own is flat. The board meeting turns into a sales meeting. A sales hire gets approved, then a second one. Most of that spend will miss, because the diagnosis is wrong. Nothing in the sales function broke after close. The growth engine was the founder, and the deal is what took him off the road.

Where the customers came from

Ask an MSP where its clients come from and you get one answer. In the ConnectWise 2026 MSP marketing report, 72 percent of MSPs called referrals a key driver of business, and no other channel came close. A campaign is something you buy. A referral is a relationship, and at a founder-built firm the relationships belong to the founder: the peer who runs a company across town, the accountant who sends over two clients a year. That engine is real, it is nearly free, and it built the business you bought. It has one moving part. The deal did not include it.

Nobody wrote the engine down

Here is the number I would put in front of a board. Only 43 percent of MSPs have a formal referral program, meaning an owner, an ask, an incentive, and a line in a monthly report. The industry’s best channel mostly runs on habit and goodwill. And where a program does exist, the dependence runs deep: among MSPs with referral programs, one in three reports that referrals produce more than half of total revenue. Take both numbers together as an owner. The typical MSP’s best source of new business is unmanaged, and when it is managed, it often carries half the company.

Nothing sits underneath it

The natural question is what takes over once the founder’s network is spent. Usually, nothing. Half of MSPs in the same report, 51 percent, spend less than ten thousand dollars a year on marketing in total. The best-in-class benchmark, drawn from Service Leadership data, is 1.8 percent of revenue, which works out to eighteen thousand dollars for a million-dollar firm. Even the top of the class funds demand like a hobby. So it is no surprise that in Kaseya’s 2026 survey of more than a thousand MSPs, 71 percent named acquiring new customers their biggest challenge, ahead of every other problem in the business. The industry is telling you, in its own numbers, that it never built a machine for winning customers. It had founders instead.

The people pricing your debt have noticed

PitchBook’s private-credit coverage put the pattern in print back in 2024: MSPs typically show little organic growth under sponsor ownership, growth the company makes on its own, because most of the customers worth having already have a provider and prying them loose is slow work. Reed Van Gorden, head of originations at the lender Deerpath Capital, said it plainer in the same piece: “if some of these MSPs can figure out what new services to offer to increase organic growth, that would be the holy grail. We just haven’t really seen that happen yet.” Lenders keep financing MSPs anyway, because the cash flow is that dependable. They have simply stopped underwriting the growth. An equity case cannot afford the same shrug.

What the owner does about it

Four moves, all boring, all doable inside a quarter.

Map the engine while its parts still work. Take every client won in the past five years and write down who made the introduction. Do it while the founder is still under contract; the map is worth little once the goodbye tour ends.

Make referrals a channel instead of a habit. Give the channel an owner, a budget, a standing ask in every client review, and a report that counts introductions the way a sales report counts calls.

Fund demand like a line of business. If eighteen thousand dollars per million is what best-in-class spends, treat that as a floor, and measure the spend in customers won, not in leads.

Then ask one question at the next board meeting: of the new clients we signed in the past twelve months, how many came by referral, and who made each introduction? If the answer is a list of names with the founder’s at the top, the growth stall has a different name. It is succession, sitting inside the revenue line.

Build it during the hold

The rare platform that grows without buying says the same thing from the other side. “If you can’t grow what you own, you shouldn’t be buying more,” Evergreen’s Ramsey Sayhoun told CRN in February. What the fund bought was a company that never needed a growth engine, because for twenty years it had something better: a founder people trusted, selling to people who trusted him. That engine leaves in every deal, on a schedule the deal itself sets. The replacement does not arrive with a hire. It gets built, during the hold, and building it is the work.
