Every allocation to an alternative investment is a decision made with incomplete information about an illiquid position that cannot easily be reversed. Due diligence is the structured attempt to reduce that incompleteness before the decision rather than after it.
It is also, in the intermediated part of this market, a regulatory obligation rather than a matter of prudence — which changes what a defensible process looks like.
The two halves
Serious diligence separates into two workstreams that ask fundamentally different questions.
Investment due diligence asks: is this a good investment? Strategy, market opportunity, sourcing, underwriting discipline, portfolio construction, track record, and terms.
Operational due diligence asks: is this a real business, and is my money safe? Legal structure, service providers, valuation governance, cash controls, compliance, technology, key personnel, and financial condition of the management company.
Both matter. The reason they are separated — and in institutional settings performed by different teams reporting through different lines — is that the investment questions are more interesting and will otherwise consume all the available attention. Meanwhile, the failures that destroy capital most completely tend to be operational rather than analytical.
The distinction is developed in operational vs. investment due diligence.
The process
1. Screening. Does this fit the mandate at all — strategy, size, vintage, eligibility, liquidity profile? Most opportunities should end here, and a process that advances everything is not screening.
2. The questionnaire. A structured DDQ covering the manager, strategy, team, track record, terms, operations, and compliance. Standardised templates exist and make responses comparable across managers.
3. Document review. The private placement memorandum, partnership agreement, subscription documents, audited financial statements, service provider agreements, and Form ADV where applicable. The governing documents matter more than the marketing, and they frequently differ from it in ways worth finding before rather than after.
4. Investment analysis. Track record verification, attribution, portfolio review, and an assessment of whether the stated edge is real and repeatable. See evaluating a sponsor track record.
5. Operational review. Service providers confirmed independently, valuation process examined, controls assessed, and the management company financial condition understood.
6. References and confirmations. Existing investors, service providers contacted directly rather than through the manager, and background checks on principals.
7. On-site meetings. Meeting the operations, finance, and compliance people, not only the investor relations team. What the back office says when the marketing team is not in the room is frequently the most informative part of a diligence process.
8. Documentation and decision. A written record of what was examined, what was found, what concerns remain, and why the decision was made.
That last step is the one most often shortened and the one that matters most later. A decision that was reasonable but undocumented is difficult to distinguish, in hindsight, from one that was never made carefully.
What experienced reviewers actually look for
Independent verification of everything verifiable. Confirm the administrator, auditor, and custodian by contacting them, not by reading a brochure. Historic frauds have involved fabricated service provider relationships, and the check costs a phone call.
Valuation governance. In illiquid strategies, NAV is produced by a process, not observed. Who determines marks, what independent input exists, how disagreements are escalated, and whether the methodology has been consistent.
Cash controls. Who can move money, whether dual authorisation is enforced technologically, and how changes to payment instructions are verified.
Investor-facing compliance. Whether the manager can identify who its investors actually are, which is the subject of AML and KYC for private funds.
Key person concentration. What happens if one or two people leave, and whether the documents provide for it.
Alignment. How much the principals have invested personally, and how carried interest and management fees are structured.
Terms that only matter in stress. Gate provisions, side pockets, suspension rights, amendment powers, and the manager discretion to change things unilaterally.
Consistency. Whether the marketing, the DDQ, the legal documents, and the audited financials describe the same arrangement. Inconsistencies are among the highest-value findings available, and they are found by reading rather than by asking.
The regulatory layer
For intermediaries, diligence is not discretionary.
A broker-dealer recommending a private placement has an obligation to conduct a reasonable investigation of the offering itself, independent of what it owes any particular customer. This is a firm-level obligation, and it is not satisfied by relying uncritically on materials the sponsor supplied. FINRA has addressed it directly, and FINRA Rule 2310 imposes additional requirements for direct participation programs. The subject is covered in reasonable-basis diligence.
Separately, Regulation Best Interest governs recommendations to retail customers, and investment advisers owe fiduciary duties under the Advisers Act. These are customer-specific obligations layered on top of the product-level investigation.
The practical consequence: an intermediary needs both a documented product-level file and a documented rationale for the specific recommendation. Neither substitutes for the other.
Third-party reports and their limits
A market exists of third-party due diligence providers producing reports on sponsors and programs, widely used by broker-dealers and advisors who cannot economically replicate that work in house.
These reports are genuinely valuable. They also come with a limitation that should be stated plainly: reliance does not transfer the obligation. A firm remains responsible for its own reasonable investigation, which includes assessing whether the third-party report is adequate for the purpose, current, and independent. Understanding who commissioned and paid for a report is part of reading it.
The uncomfortable truth about diligence
Diligence cannot make an illiquid, opaque investment transparent. It reduces the probability of specific, identifiable failures — fabricated returns, absent controls, undisclosed conflicts, misaligned terms — and it cannot establish that a strategy will work.
What a good process produces is not certainty but a defensible decision: one where the material risks were identified, the verifiable facts were verified, and the reasoning was recorded. That is achievable. Certainty is not, and a process that claims to deliver it is misdescribing itself.

Frequently Asked Questions
What is due diligence on an alternative investment?
The structured investigation of a fund, sponsor, or offering before capital is committed. It generally splits into investment due diligence, which examines the strategy, track record, and terms, and operational due diligence, which examines the infrastructure, controls, service providers, and governance that determine whether the strategy can be executed and the assets protected.
What is the difference between investment and operational due diligence?
Investment due diligence asks whether the strategy is sound and the manager is skilled. Operational due diligence asks whether the business is sound and the assets are safe. They are complementary and are often performed by different people, because they require different expertise and because combining them tends to let the more exciting questions crowd out the more consequential ones.
How long does due diligence take?
It varies enormously with the size of the commitment, the complexity of the manager, and whether third-party reports are used. What matters more than duration is scope and documentation: a defined process with a written record is what supports a decision later, whether the reviewer is a regulator, an investment committee, or a client.
Do broker-dealers have a due diligence obligation?
Yes. A broker-dealer recommending a private placement or direct participation program has an obligation to conduct a reasonable investigation of the offering, generally described as reasonable-basis diligence, independent of any obligation owed to a specific customer. FINRA rules and the SEC best interest standard both bear on this.
Can due diligence be outsourced?
Parts of it. Third-party due diligence providers produce reports on sponsors and programs that many broker-dealers and advisors rely on. Reliance does not transfer the obligation — the firm remains responsible for its own reasonable investigation and for evaluating whether the third-party work is adequate for its purposes.
