What a Limited Partner Is Actually Testing When They Diligence Your Fund
Most due-diligence guidance is written for the investor doing the diligencing. Here's what it actually tests, from the fund's side of the table.

A data room request lands a few weeks into a raise, and it doesn't read like anything your deck prepared you for. Track record slides and a clean waterfall got the meeting. This list asks about your cybersecurity incident history, who besides you can move cash, and what happens to the fund if you're unreachable for a month. It feels like an audit bolted onto a pitch process, because in a real sense it is.
Diligence Is Three Tests Wearing One Form
Every due-diligence questionnaire reads as a single undifferentiated list, so most GPs answer it as one task: fill in the boxes, attach the policies, send it back. That treats three genuinely different evaluations as one paperwork exercise, and it shows in the quality of the answers. An investor reading your responses is quietly sorting them into three buckets, and each bucket is judged on a different standard.
Test one: can you actually do what the deck says
This is the test most GPs prepare for without realising it's a separate test — it's simply the pitch, examined more slowly. Reviewers look past the headline numbers to where the deals actually came from and who in the fund can speak to each one with real detail. If one partner sources most of the opportunities and carries every relationship personally, the fund looks less like a team and more like one person wearing a team's letterhead.
That doesn't disqualify a fund on its own — plenty of strong funds are built around one clear decision-maker. What it does is push the question into test two, because concentration of judgment and concentration of risk turn out to be the same thing viewed from different angles.
Test two: what happens if you're not there
Every fund's limited partnership agreement has a key-person clause, and it is read far more carefully than most GPs expect. It names the person, or people, whose departure, incapacity, or reduced involvement can trigger a suspension of the investment period — a mechanism, not a formality, that stops new capital going out until LPs are satisfied the fund can still function.
Solo GPs and small teams draw the sharpest version of this question, not because running lean is disqualifying, but because the fallback plan has to be explicit rather than assumed. What happens to a pending investment, or to an existing portfolio company that needs a follow-on decision, if the named person is unreachable for an extended stretch? LPs want that answer in writing, not inferred from how capable you seem in the room.
Test three: does the back office function once capital is actually in the door
This test rarely shows up in a pitch deck because it isn't a pitch question. It looks past the investment thesis entirely, to who the fund administrator is and what they independently verify rather than simply process on your instruction, how a wire gets approved, and who signs a capital call notice before it goes out.
The sharpest version of it: can you, alone, both request a wire and approve it? If the answer is yes, that's not a judgment about your integrity — it's the absence of a control that's supposed to exist independently of trusting any one person, including you.
Where this catches GPs who prepared seriously for test one
The funds that stall in diligence usually aren't thin on track record — that story gets rehearsed for months before a raise opens. They stall because nobody asked them about succession or cash controls in earlier conversations, so the answers were never written down, only assumed to be fine.
Diligence isn't adversarial, even when it reads that way
It's easy to read a sprawling questionnaire as an LP who doesn't trust you. More often it's the opposite: a reasonable institution putting a real process behind capital it's answerable to its own investors for. An LP that skips operational diligence isn't being generous — it's failing its own duty to the people whose money it is deploying. Treating the questionnaire as adversarial is usually what produces thin, defensive answers; treating it as the part of the process where you get to show the fund actually works tends to produce better ones.
Questions worth having honest, written answers to
- If you were unreachable for a month, who could approve a capital call or release a wire?
- Does your key-person clause name one person or a defined group, and what exactly does it let LPs do?
- Who is your fund administrator, and what do they independently check rather than simply process?
- Can anyone besides you move cash, and what has to happen before they can?
- If an LP called your fund administrator directly, would the answer match what you'd tell the LP yourself?
- What's actually documented, versus what only exists in your head?
Building the controls and documented processes that hold up under this kind of scrutiny is the kind of financial services work we focus on — not writing answers for diligence, but making sure the answers are true before anyone asks.

Frequently asked questions
What's the difference between investment due diligence and operational due diligence?
Investment due diligence tests whether the strategy and track record hold up — the sourcing, the decisions, the returns. Operational due diligence is a separate track that looks at the back office: who the fund administrator is, how cash moves, who can approve what, and whether those controls exist independently of any one person.
What does a key-person clause actually allow an LP to do?
It names the person or people core to the fund and sets out what happens if one of them departs, becomes incapacitated, or can no longer devote the agreed time — typically a suspension of the investment period until LPs are satisfied the fund can still function. The exact trigger and remedy are set out in your limited partnership agreement, so read your own clause rather than assume a standard one applies.
Why do LPs ask so specifically about fund administrators?
Because a fund administrator who only processes what the GP instructs provides no independent check, while one who verifies valuations, reconciles cash, and confirms capital calls independently gives LPs a control that doesn't rely on trusting the GP alone. LPs are testing which kind you have.
Does running a solo-GP fund automatically fail key-person diligence?
No. Solo funds are common and not disqualifying on their own. What LPs want is an explicit answer for what happens to pending decisions and existing portfolio companies if that one person is unreachable for an extended stretch — written down, not assumed.
What's the most common reason a fund stalls in diligence after a strong first meeting?
Usually not the track record — that story is well rehearsed by the time a raise opens. It's typically one of the other two tests: a key-person clause nobody has thought through, or operational controls that exist informally rather than as documented, independently verifiable processes.
Should a GP volunteer operational details an LP hasn't asked about yet?
Generally yes, within reason — volunteering your key-person provision and your fund administrator's role early, before a questionnaire forces it out of you, tends to read as a team that already knows where it stands rather than one improvising an answer under scrutiny.
