Family offices that have spent years investing through private equity funds are now deploying capital directly into operating businesses, bypassing the fund layer to reduce fees and gain more control over underlying assets. The transition is logical. It also exposes a gap that most families do not discover until they are already committed: the diligence a fund manager runs on their behalf is nothing like the process a family office needs to run on its own.
Why direct investment diligence is different
When a family office invests into a fund, the general partner carries out commercial, financial, legal, and operational diligence before deploying. The family receives a summary and a capital call. When the same family invests directly into a business, every one of those workstreams becomes their responsibility. There is no GP to absorb the complexity. The family's internal team, often a small investment office with a generalist mandate, is now the buyer. Without a structured process and independent advisers, the gaps in that coverage become the risks that materialise post-close.
The second difference is the deal profile. Family offices making direct investments tend to operate in the sub-50 million enterprise value range, frequently alongside a management team or a co-investor. At that size, the target business typically does not have audited accounts prepared to acquisition standard, may not have a financial controller, and almost certainly does not have a data room in any meaningful sense. The diligence process must be designed for what the business actually is, not for the institutional-grade information environment a large-cap deal assumes.
What a thorough diligence process covers
A well-structured direct-investment diligence process for a family office has four workstreams running in parallel, each with a clear owner and a defined output.
Financial diligence goes beyond reviewing the last three years of accounts. It reconstructs the underlying earnings on a normalised basis, stripping out owner remuneration that will not persist post-acquisition, one-off items that inflated a particular year, and related-party transactions that distort the margin picture. For an owner-managed company, this normalisation work routinely changes the effective purchase multiple by a material amount, and it must be completed before price is fixed.
Commercial diligence tests whether the revenue model is as durable as management represents. Who are the top customers, what are the contract terms, and what would it take for them to leave? Is the revenue concentrated in a way that creates a binary risk? Does the business have pricing power, or is margin dependent on a cost base it cannot control? These questions require structured interviews with customers, suppliers, and competitors, combined with a review of the commercial pipeline and win/loss history.
Legal and structural diligence covers ownership history, the enforceability of key contracts, intellectual property assignments, and any undisclosed litigation or regulatory exposure. Owner-managed businesses often have structural informality that creates real risk post-close: unsigned agreements, verbal understandings with key staff, licences that lapse on change of control.
Management and operational diligence assesses whether the business can continue to operate without the founder. In many businesses at this size, the processes, the customer relationships, and the institutional knowledge sit with one person. Key-person dependency is among the most common sources of post-close value destruction in direct investment at this end of the market.
Common mistakes family offices make
The first mistake is sequencing diligence after heads of terms. A family office that agrees a price and then discovers a material normalisation adjustment or a structural defect is negotiating from a weak position. The practical sequence is to run at least the financial normalisation and a preliminary commercial assessment before locking price, then complete the remaining workstreams during exclusivity.
The second mistake is using the seller's advisers as a proxy for independence. A seller-side information memorandum is a marketing document. The numbers reflect the most favourable presentation of the business, not a neutral reconstruction. Accepting the seller's figures without independent verification is how families find that the business they bought is not the business they thought they were buying.
The third mistake is under-resourcing the process to keep costs proportionate to deal size. A smaller deal does not require less diligence rigour. The consequences of a missed risk scale with the proportion of a family's net worth deployed, not with the absolute deal size. Cutting diligence to save fees is one of the more reliable ways to destroy capital in direct investing.
What to prepare as a family office buyer
Before engaging advisers, a family office needs to define its investment thesis clearly enough that diligence can be structured around it. If the thesis is growth under new management, commercial diligence should be weighted heavily. If the thesis is stable cash generation, financial diligence and customer retention data take priority. A generic checklist applied without a thesis produces a lot of information and very little insight.
Internal governance matters. The family office needs a clear decision-making process covering who can approve entry into exclusivity, who signs off on the diligence findings, and who has authority to walk away if a material issue emerges. Deals at this size move quickly, and decisions made under pressure tend to discount findings that should be deal-breakers.
Working with advisers at this deal size
The most effective structure for a family office at the sub-50 million end is a small, senior team of independent advisers working across the financial and commercial workstreams together. The value is in the judgement applied to the findings, not in the volume of the output. An adviser who has seen comparable businesses and can tell you that the gross margin trajectory looks unusual is more useful than a voluminous report that buries the same observation in a footnote. Advisers who understand the owner-managed business context will consistently identify risks that a large-firm team working from a standard protocol will not.
