Diligence with the manager as the subject

    A commitment to a fund is a commitment to the people running it, usually for a decade. Manager diligence asks whether the track record is attributable, whether the process is repeatable, and whether the operational and governance foundations hold. Reuben AI structures that assessment so it is evidenced rather than a matter of impression formed in meetings.

    This is the evidence-building phase of Reuben AI's living decision record. Research sources, findings, assumptions and unresolved questions stay connected as the record moves into investment committee review and, after a decision, ownership.

    Track record that can be attributed

    Performance presented at firm level rarely answers the question an allocator is actually asking, which is what this team did and which decisions were theirs. Diligence at manager level separates realised from unrealised, examines what drove the outcomes, and tests whether the people presenting the record were the people responsible for it. Where attribution cannot be established from evidence, that is recorded rather than assumed in either direction.

    Team, decision rights and succession

    Who sources, who decides, who can veto, and what happens if a named partner leaves. Decision rights on paper and decision rights in practice are frequently different, and the difference matters most in a downside case. Reference and back-channel input is captured with attribution and weighted separately from formal references, because the two are not equivalent evidence.

    Process consistency across deals

    A manager describing their process is describing an intention. Comparing the described process against how a sample of deals was actually worked is the assessment. Where the firm can show a structured, evidenced record of its own diligence across deals, that answer becomes straightforward, which is one reason managers running an evidenced process fundraise on stronger ground.

    Operational diligence

    Valuation policy and who applies it, cash controls and authorisation, service providers including administrator, auditor and custodian, conflicts and allocation policy, cyber and data handling, business continuity, and regulatory permissions in each jurisdiction the firm operates in. This is the workstream most often compressed into a questionnaire, and it is the one where an evidenced answer is most valuable.

    Governance and the ongoing record

    Manager diligence does not end at commitment. Advisory committee arrangements, reporting obligations, side letters and the manager's actual reporting behaviour over time all belong on the same record. A living manager profile means the annual review starts from a maintained assessment rather than being rebuilt from scratch each year.

    Diligence at every level, rolling up to the portfolio

    Diligence runs at six levels: the asset or company, the deal, the vehicle, the fund, the manager and the portfolio. Findings at each level connect, so a single holding can be read through its deal, vehicle and fund to the manager, and out to the full portfolio it sits inside.

    Company and asset level

    Diligence with the company or asset as the subject: documents, financials, cap table, contracts and market position, each finding bound to its source.

    Company and asset level

    Vehicle level

    Diligence with the vehicle as the subject: SPVs, co-investment and continuation vehicles, feeder and parallel structures, terms, governance and jurisdiction.

    Vehicle level

    Fund level

    Diligence with the fund as the subject: structure, terms, jurisdiction, portfolio construction and existing holdings assessed through to underlying holdings.

    What makes the diligence deep

    Diligence is only as good as the context behind the questions it asks. Credit diligence and venture diligence do not ask the same things, a fund in one jurisdiction is not assessed like a fund in another, and a company profile that stops updating at signing stops being useful. Asset class coverage, jurisdiction and vehicle structures, market research and continuously updating company and manager profiles all feed the same diligence record.

    Asset class coverage

    Native asset classes and sub-asset overlays, so evidence requirements differ by what is being assessed.

    Market research

    Market structure and comparables attached to the deal rather than held in a separate document.

    Questions we are asked in diligence demos

    Is this the same as an operational due diligence review?

    Operational diligence is one workstream within manager diligence, covering valuation policy, controls, service providers, conflicts, technology and continuity. Manager diligence also covers track record attribution, team and process.

    Can it work from a completed questionnaire?

    Yes. A completed questionnaire is treated as self-reported evidence and tiered accordingly, then tested against independent documents where those exist. The distinction between what was asserted and what was verified stays visible.

    Is it useful for managers as well as allocators?

    Yes. Managers preparing for allocator diligence use the same structure to assemble an evidenced answer to the questions they will be asked, including how their investment process actually runs.

    How does it connect to the funds a manager runs?

    Manager, fund and holding records are connected, so an assessment of the firm sits alongside the vehicles it runs and the holdings inside them, and exposure can be read across every level up to the full portfolio.

    Manager due diligence: track record, team and alignment

    Manager due diligence assesses the general partner behind a fund: track record across funds, attribution of returns to the team that will manage the new fund, strategy consistency, terms and alignment, and operational quality.

    Track record review should separate realised from unrealised value and show how marks were set. Findings should stay with the manager so every later fund and co-investment decision can use them.

    How it works on one record: Reuben AI connects evidence across the asset or portfolio company, deal, vehicle, fund, manager, portfolio. Track record attribution for a manager informs each fund and co-investment decision with that manager. The same fully sourced record carries context from discovery through diligence, committee decisions and ownership review. Judgement stays human.

    What is manager due diligence?

    The assessment of a fund manager's track record, team, strategy, terms, alignment and operations before committing to its fund.

    How do you assess a manager's track record?

    Separate realised and unrealised value, check how marks were set, and attribute returns to the people who will manage the new fund.
