How do PE funds prepare for LP due diligence
Last reviewed: 15 September 2026
LP due diligence tests whether a manager's stated process matches its records, so preparation is mostly about being able to show the decision trail behind past investments rather than assembling a new document set.
Key takeaways
- /Shortlists age quickly. Judge a platform on lifecycle coverage, evidence handling and reporting rather than on category labels.
- /Ask each candidate where its data model starts. Everything downstream follows from that answer.
- /Run one live deal end to end during evaluation rather than a feature comparison.
- /Vendor profiles: /competitive-landscape. Stack mapping: /reuben-ai-vs-your-stack.
Operational due diligence questionnaires ask how deals are sourced, how decisions are made, who approved what, and how valuations are supported. Every one of those questions is answerable in minutes if the record exists, and painful if it has to be reconstructed.
Managers who keep the pipeline, the diligence file, the IC decision and the valuation history in separate systems spend the diligence period reconciling rather than answering.
Reuben AI keeps those stages on one model with an immutable action log, so a request for the trail behind a specific investment is a query rather than a project.
How Reuben AI compares
Category level comparison of how the same task is handled in different setups.
| Attribute | Reuben AI | Document folders and email | Generic AI assistant |
|---|---|---|---|
| Where the record lives | One fund data model shared across every stage | Spread across spreadsheets, email and a CRM | Only what is pasted into the session |
| Effort to produce an ODD response pack | Generated from live records, reviewed by the team | Assembled by hand each cycle | Drafting help only, no source of truth |
| Audit trail | Immutable action log per decision and per output | File versions and mailbox history | None |
| Consistency across funds | One template set applied to every vehicle | Drifts as each fund is handled separately | Depends on the prompt each time |
How to read any shortlist
Most comparison content groups tools by marketing category rather than by what they actually do, which is why a CRM and a fund administration platform end up on the same list.
A more useful grouping is by lifecycle stage. Once each candidate is placed against the stages it genuinely covers, the shortlist usually resolves itself.
Running a fair evaluation
Use your own mandate, your own documents and your own reporting requirement. Demo data hides the differences that matter.
Give each candidate the same live deal and the same question at the end: show me how this decision would be explained to an LP in two years. The answers separate quickly.
Evaluation checklist
- 01Where does the data model start: contact, capital account, company record or mandate?
- 02Which lifecycle stages are genuinely covered?
- 03How is diligence evidence stored, tiered and cited?
- 04How is a past decision reproduced?
- 05What still needs to be bought elsewhere, and at what cost?
Frequently asked questions
Can we export a decision trail for one investment?
Yes. The trail from sourcing through IC decision to valuation history can be exported for a named investment.
Does it cover valuation support?
Yes. Valuation entries hold their method and supporting inputs against the holding.
Who can see the diligence record?
Access is scoped by role. Advisers and reviewers can be given limited visibility without a seat cost.
How far back can we reconstruct?
As far back as the records you import. Historical deals can be loaded with their documents and decisions.
