What is an IC Memo?
Short answer
What is investment memo?
An investment memo is a decision document that explains an opportunity, its supporting evidence, material risks and the recommendation presented to the investment committee. Reuben AI connects the memo to diligence so reviewers can trace claims and see what remains unresolved.

Definition and scope
Investment memo is a structured part of an investment process, with an identifiable question, an evidence base and an accountable handoff. Its purpose is not to produce more paperwork. It is to make the reasoning behind a recommendation understandable to someone who did not conduct the original research. The scope should reflect the investment mandate, the asset or entity under review and the decision being requested. A useful record separates facts, assertions, assumptions and unresolved questions. It also states the limits of the work, including areas that require specialist review. This guide describes a practical process rather than a promise about investment outcomes.
Reuben AI is decision infrastructure for private capital. It brings diligence, research and the investment committee into one connected record, so every decision is consistent, evidence-based and traceable to its source. Judgement stays human. The process becomes disciplined.
How it works, step by step
Start with the requested decision
State the recommendation, the proposed transaction context and the questions the committee must resolve. Explain why the opportunity fits the mandate. A reader should understand what is being asked before encountering the full history of the deal.
Develop the thesis from evidence
Explain the business or asset, the market context, the investment rationale and the assumptions behind it. Link material statements to supporting sources. Separate historical facts from forecasts and identify which claims still depend on management representations.
Make risks and alternatives reviewable
Describe downside cases, conflicting evidence and reasons to decline or defer. Explain the consequence of each unresolved issue for the recommendation. A risk section should help reviewers decide, not simply show that the team has named familiar categories of risk.
Close with conditions and review
Set out the proposed decision, required follow-ups and the matters that need specialist advice. Check the narrative against the underlying evidence before circulation. After committee, connect the approved rationale and conditions to the record used during ownership.
Review checklist
- The scope and requested decision are explicit, and the relevant mandate is attached.
- Material claims have supporting sources, with limitations and conflicting evidence visible.
- Facts, management assertions and analytical assumptions are distinguishable to the reader.
- Open questions have owners and consequences for the recommendation, rather than unexplained status labels.
- The receiving reviewer can find the rationale, accepted risks and any required specialist advice.
- Conditions and follow-up responsibilities carry into the next stage without losing their original context.
Common mistakes
- Writing the conclusion before testing the thesis
- Copying unsupported statements into successive drafts
- Treating the memo as a substitute for the committee decision
These mistakes have a shared cause: the summary becomes detached from the work behind it. Before a handoff, ask a colleague to trace a material conclusion back to its source and explain what would change the recommendation. If they cannot do that, clarify the reasoning before polishing the presentation. A concise qualification is more useful than an unsupported conclusion, and an explicit open question is more useful than an empty field that looks complete.
Worked example: illustrative
Illustrative example, not a client case study: consider an investment team drafting a memo for a proposed acquisition. The team begins by writing the decision question and linking the initial thesis to the material available. A management presentation supports the proposed opportunity, but a supporting document leaves an important assumption uncertain. The analyst records the disagreement rather than smoothing it into a positive summary. The workstream owner requests the underlying evidence and explains how the answer could change the recommendation. When the response arrives, the reviewer checks whether it addresses the actual question, records its limitations and updates the finding. The committee sees both the revised view and what remains open. If it proceeds subject to a condition, that condition moves into ownership with a named owner. A later review compares new information against the same assumption. The example illustrates the chain from evidence to judgement without assuming that the investment succeeds or inventing commercial results.
Evidence and interpretation
A reference guide is useful only if a reader can distinguish what is known from what is inferred. Give each important claim a source, explain the source’s relevance and keep any qualification beside the conclusion it affects. A source can be genuine and still be insufficient for the decision. For example, a statement about a broad industry may not apply to a particular customer segment, contractual arrangement or jurisdiction. The reviewer should be able to follow the reasoning without guessing which passage mattered. Where sources conflict, explain the conflict and the next question rather than silently selecting a preferred version.
Ownership and review discipline
Name the person responsible for the next action and explain what would count as a satisfactory response. A request to obtain more information is not complete until someone has considered what that information means. The review should distinguish a closed question from an accepted risk and from a matter outside scope. Preserve the reason for each status so another colleague can continue the work. If the scope changes, record the change explicitly. This makes the process usable when responsibilities move between research, diligence, committee preparation and portfolio oversight, without suggesting that a standard template replaces professional judgement.
Boundaries and handling sensitive material
Use only information the team is authorised to access and share. Confirm the appropriate audience before circulating a source or a summary derived from it, particularly when external advisers or platform partners are involved. Keep the decision record separate from any suggestion that software provides legal, tax or investment advice. Teams remain responsible for their governance arrangements and the decisions they make. Deployment and integration requirements should be scoped with Reuben AI rather than assumed from a workflow description. A useful evaluation starts with the team’s evidence and review requirements, then checks how the proposed setup supports them.

Questions in this topic
Frequently asked questions
- What is the purpose of investment memo?
- An investment memo is a decision document that explains an opportunity, its supporting evidence, material risks and the recommendation presented to the investment committee. Reuben AI connects the memo to diligence so reviewers can trace claims and see what remains unresolved.
- Does Reuben AI make the investment decision?
- No. People assess the evidence, challenge the recommendation and make the decision. Reuben AI connects the material used in that process; it does not give investment advice.
- How should unresolved questions be handled?
- Keep them visible beside the recommendation, with an owner, the evidence requested and the consequence for the decision. Distinguish a question that has been answered from a risk the decision makers knowingly accept.
- What makes a source useful for review?
- The source must support the particular claim being made, within its actual scope. Record the relevant document context, distinguish assertions from checked findings and explain any contradictory evidence.
- When should the record be reviewed again?
- Review it when new evidence could change a material assumption, when a decision condition requires follow-up or when the organisation’s review process calls for it. Preserve the earlier rationale when recording a changed view.
- Where is data stored?
- Data residency is available in APAC, EMEA or the Americas, with the region agreed during onboarding.
An IC memo, short for investment committee memo, is the primary decision document a deal team produces to seek approval from the investment committee. It records the opportunity, the evidence gathered during diligence, the key risks, and the recommendation on whether to invest, at what price, and on what terms.
Why the IC memo exists
An investment committee is asked to approve capital deployments in a short meeting, often with limited time to read new material. The IC memo compresses weeks of diligence into a structured document a partner can absorb quickly and challenge on substance.
The memo also serves a second purpose. It becomes the permanent record of what the fund knew, what it assumed, and why it decided to proceed or pass. Years later, when portfolio performance is reviewed or LPs ask why a bet was taken, the IC memo is the source of truth.
Standard IC memo sections
Format varies by firm and strategy, but most institutional IC memos cover the following:
- Executive summary and recommendation. One page. The proposed investment, the amount, the ownership, the price, and the clear recommendation.
- Opportunity and thesis fit. What the company does, why it matters now, and how it maps to the fund's stated strategy.
- Market and competitive dynamics. Size, growth, structural drivers, adjacent players, and how the company is positioned.
- Team and founder assessment. Backgrounds, prior operating experience, reference checks, and the reason to back this team.
- Product and technology. What has been built, defensibility, roadmap, and technical risks.
- Financials and unit economics. Historical performance, forward plan, key assumptions, and sensitivities.
- Deal terms and structure. Round mechanics, valuation, governance rights, and exit alignment.
- Risks and mitigants. The genuine downside scenarios and how the fund plans to manage them.
- Appendices. Detailed diligence outputs, references, model outputs, and supporting evidence.
Common pitfalls
The most common failure mode is a memo that reads as advocacy rather than analysis. When the recommendation is clear from page one and every subsequent section is written to defend it, the committee is not receiving a decision document. It is receiving a sales pitch.
A second pitfall is thin evidence. When claims about market, moat, or team are asserted without underlying sources, the committee cannot separate what the deal team knows from what it hopes. Every meaningful claim should trace back to the primary source in diligence.
The third is length without structure. A fifty page memo that hides the recommendation and cannot be navigated wastes committee time and pushes partners to skim the parts that most need scrutiny.
How modern funds produce IC memos
Traditionally, IC memos were assembled by hand in Word or Google Docs from scratch for each deal. Diligence outputs, model results and reference notes were copied across, formatted, and passed between analysts and partners over several drafts.
Modern investment platforms draft the memo directly from the diligence workspace, with every claim linked to the underlying source. The deal team edits and challenges the draft rather than rebuilding it. Dissent, votes and follow up conditions are captured alongside the memo, so the record of the decision is preserved with the reasoning that produced it.
Automating IC memos with Reuben AI
Reuben AI drafts IC memos from the live diligence record, preserves dissent and votes, and keeps the full decision provenance for the life of the fund.
Key components of a great IC memo
A great IC memo has eight components, each with a job in the committee. The recommendation and ask states what the team wants approved, so members know the decision before they read the case. The thesis explains why the opportunity fits the mandate. The company or asset section describes what is being bought or financed. Deal terms and structure set out the instrument, ownership and protections the committee is agreeing to.
Key risks and mitigants show what could break the thesis and what the team will do about it. Evidence gaps and open questions list what diligence has not yet confirmed, so the committee can decide whether to proceed, condition or defer. Valuation and returns logic explains the assumptions behind the price and the downside case, with every figure traceable to a source. Conditions and next steps record what must happen after approval and who owns it.
Start the memo when diligence begins, not the week before committee. Draft the thesis and open questions first, update each section as findings are reviewed, and finalise it before the committee pack is circulated. A memo written this way reflects the diligence rather than summarising it after the fact.
The memo shapes the whole committee process. Members use it as the pre-read, challenge the thesis and risks in the meeting, record the decision and any conditions, and carry that rationale into ownership. When the investment is reviewed later, the original memo shows what the committee believed and why.
How it works on one record: Reuben AI connects evidence across the asset or portfolio company, deal, vehicle, fund, manager, portfolio. Each memo claim links to its source, and the committee decision and conditions stay attached to the same record through ownership review. The same fully sourced record carries context from discovery through diligence, committee decisions and ownership review. Judgement stays human. See the six levels of private markets diligence, the investment committee decision record and the investment committee workspace.
What are the key components of an IC memo?
Recommendation and ask, thesis, company or asset, deal terms and structure, key risks and mitigants, evidence gaps and open questions, valuation and returns logic, and conditions and next steps.
When should you start writing an IC memo?
When diligence begins. Draft the thesis and open questions first, update sections as findings are reviewed, and finalise before the committee pack goes out.
How does an IC memo inform the committee process?
It is the pre-read, the basis for challenge in the meeting, and the record of the decision and its conditions, which then carries into ownership review.
Why include evidence gaps in an IC memo?
So the committee can see what diligence has not confirmed and decide whether to approve, approve with conditions or defer.
How does Reuben AI help with IC memos?
Reuben AI builds the memo from the same fully sourced record as diligence, so every claim traces to evidence and the committee decision stays attached through the investment lifecycle.
