For family-office investment teams
A diligence memo where every material finding shows its source.
Diligence OS reviews the documents behind a private investment, links each material finding to the passage that supports it, and withholds what the documents cannot support. A named reviewer checks the memo before your team reads it.
Three reviews today: Risk Analysis, Investment Diligence, and Operational Due Diligence. Pilots run 60 days at no charge.
The auditor’s report is dated before the period it covers
The Marston Hale LLP auditor's report covers the Partnership's financial position as of 31 December 2025 but is dated 30 December 2025, one day earlier. The date needs reconciliation with the auditor. [4][5]
[4] Auditor's Report — Marston Hale LLP.pdf · page 1
In our opinion, the financial statements present fairly, in all material respects, the financial position of the Partnership as of 31 December 2025. Marston Hale LLP. 30 December 2025.
“A flat 1.5% management fee for the life of the fund.” The prospectus summary and the partnership agreement conflict, so the memo does not assert it. [2] [3]
What’s in the memo
The deliverable is a cited first read of the room, organized the way an investment committee reads: a recommendation, the findings behind it, what could not be established, and confirmation that a reviewer approved it for release.
Recommendation Watch
Reconcile the PPM headline with the full LPA §7.1 schedule, including the 1.25% post-Commitment-Period fee on Net Invested Capital. [2][3]
Recommendation. A judgement, labelled as one, with the conditions your team should resolve before relying on it.
The fee description omits the step-down in the LPA
The PPM Executive Summary describes the management fee as a flat 1.5% of Aggregate Capital Commitments, omitting the LPA §7.1 step-down to 1.25% of Net Invested Capital after the Commitment Period. [2][3]
Cited findings. Each material finding carries references that open the exact passage it relies on, with the file and page.
“A flat 1.5% management fee for the life of the fund.” Not asserted: the two fee passages conflict.
Withheld points. When the documents conflict or do not support a point, the memo withholds it and gives the reason instead of guessing.
Reviewer release. A named reviewer approves this exact version before anyone on your team can open it. Approval releases the memo; it is not an investment decision.

The approved PDF. An admin or partner can download the released memo as a PDF with the same findings, citations, and withheld points.
Available in the pilot
There are three reviews. Each engagement uses one room of documents and one review. A different decision starts a separate engagement; nothing carries over between rooms.
01
Risk Analysis
What could change your decision?
A severity-ranked risk register drawn from the uploaded data room.
02
Investment Diligence
What does the evidence say about the investment?
A cited investment memorandum covering commercial, financial, contractual, and operating evidence, with a recommendation and material risks.
03
Operational Due Diligence
Where could day-to-day operations break down?
A cited operational memorandum covering controls, governance, service providers, and operational dependencies, with control gaps and follow-ups.
Who does what
You don’t operate this alone. Our reviewer reads every draft before your team sees it, and the investment decision stays with you.
The software
- Checks each file before its text is used.
- Runs the one review you chose over the documents in the room.
- Links each material finding to the passage that supports it.
- Withholds what the documents cannot support, and says why.
It uses large language models to read and draft. A model draft of the memo never reaches your team until a reviewer releases it.
A Diligence OS reviewer
- Reads the draft against its sources.
- Attests to the exact version and document set.
- Releases the memo, or sends it back for revision.
Until release, your workspace shows only “Under review”.
Your team
- Opens any citation to read the passage behind it.
- An admin or partner downloads the approved PDF for the committee.
- Makes the investment decision.
Release approves the memo for your team to read. It is not investment approval.
Pilots run 60 days at no charge.
You get all three reviews, up to 10 analyses a month, and a reviewer on every memo. Nothing renews when the 60 days end. If you want to continue, we agree a price in writing first.
We record each pilot’s security checks before any documents go in, and some hosted checks are still open.
