What size companies do private equity firms acquire?

What institutional buyers expect from a founder-led company comes down to four things: financials they can rely on, a business that runs without its founder, customers and contracts that hold up, and a credible plan to grow. Diligence tests whether today's earnings will continue after you step back.
A private equity firm or family office has shown interest, and you have never been through institutional diligence. It will not feel like your conversations with customers or lenders. The buyer is trying to answer one question: will this company keep earning and growing once you are no longer the center of it?
Financials a buyer can rely on are consistent, reconciled, and explainable by someone who does not work for you. In practice that means:
The test is usually a quality of earnings review, an independent report on how reliable and sustainable your earnings are. The U.S. Small Business Administration describes one for loan-financed purchases of $3 million or more. It reconciles the seller's statements, tax returns, internal statements, and tax-transcript data into a normalized earnings figure, and it documents adjustments such as non-recurring items, above- or below-market owner compensation, related-party transactions, deferred maintenance, and differences between cash-basis and accrual-basis reporting. A fractional CFO (a part-time finance leader) can run the close and keep the add-back schedule: see whether your company needs one.
A buyer pays for earnings that continue, and earnings that depend on one person may not. Buyers look for management depth: someone who owns each function, decision rights that are written down, procedures that someone else can follow, and customer relationships held by more than one person. You do not need a full executive team. You do need at least one or two people who have shown they can lead, and a plan to keep them through the sale.
If the honest answer to "what happens if the founder is out for a month?" is "we don't know," a buyer will price that uncertainty, usually through a lower offer, an earn-out, or more of the price held back.
Diligence can turn up things owners have not looked at in years. These are worth checking first:
None of these ends a deal on its own. SRS Acquiom's 2026 report on deals of $50 million or less says that such deals "tend to either surface more issues during due diligence or see buyers feeling less confident in the completeness and accuracy of the data room and, as a result, generally feature longer survival periods and larger escrows." Finding the problem first lets you fix it, or explain it, before the buyer does.
In one page: who you serve, why they stay, how the business makes money, and what the plan is for the next three years, with the numbers behind each claim. A buyer tests every claim against your records, so write nothing the data room cannot support. Growth you can show in monthly results is worth more than growth you describe.
If you want help with steps 1 and 2, our M&A advisory work covers the valuation, the quality-of-earnings review, the financial model and data room, and the materials a buyer asks for. Exit optionality shows how to start before you have decided to sell.
No. A buyer looks for depth, not size: clear roles, documented procedures, and one or two people who have shown they can run a function without you. A smaller company can show that with a short org chart and a written account of who decides what.
Not necessarily, though the bar differs by buyer. What size companies private equity firms acquire covers the size question, and the preparation above helps with any buyer.
