Investment committee memos are the most judgment-intensive documents in deal execution. They require synthesis of financial analysis, due diligence findings, valuation work, and deal structuring — and the conclusions they contain are the banker's professional opinion on whether a deal makes sense for the client. Claude Cowork does not replace that judgment. What it replaces is the 4-5 hours a VP or senior associate typically spends writing the first draft from scratch.
The complete investment banking Cowork guide covers the full workflow landscape. This article focuses on the specific process of using Claude Cowork for deal memo production — from the prompt templates that generate IC memo first drafts to the workflow for iterating and refining the output before senior review. For teams that want to deploy this alongside the due diligence workflow and pitchbook research workflow, our Cowork deployment service bundles all three into a single deployment engagement.
The Standard IC Memo Structure — and Where Cowork Helps Most
Investment committee memos follow a consistent structure across most advisory firms, though the house style and depth varies. Here is the standard IC memo structure and Cowork's relative impact on each section:
Section 1: Transaction Overview — HIGH COWORK IMPACT
Deal structure, consideration, use of proceeds, timeline to close. Cowork extracts this directly from the term sheet, CIM, and deal correspondence — no interpretation required. Output is typically 90%+ usable with minor formatting edits.
Section 2: Business Description — HIGH COWORK IMPACT
Company overview, market position, revenue breakdown, and operating model. Cowork synthesises this from the CIM and management presentation into structured IC format. Analyst review required for current accuracy but framework is complete.
Section 3: Investment Thesis — MEDIUM COWORK IMPACT
Why this deal creates value. Cowork drafts the structural arguments from source documents; the senior banker adds client-specific context, deal dynamics, and strategic framing that require human judgment. Expect 60-70% usable as a starting point.
Section 4: Financial Summary — HIGH COWORK IMPACT
LTM financials, margin profile, growth rates, working capital dynamics. Cowork extracts from the financial model export and management accounts — clean, consistent, and cross-checked against multiple source documents.
Section 5: Key Risks and Mitigants — HIGH COWORK IMPACT
Synthesised directly from the due diligence tracker and red flag extraction. If the Cowork due diligence workflow has already been run, this section populates from existing outputs with minimal additional prompt work.
Section 6: Valuation — LOW COWORK IMPACT
Implied multiples vs comps and precedents. Cowork can format the valuation summary table from the model export, but the valuation judgments — what multiple range is appropriate, how to weight the methodologies — remain senior banker decisions.
Section 7: Open Issues — MEDIUM COWORK IMPACT
Outstanding diligence items and pre-closing conditions. Cowork pulls from the diligence tracker open items list and categorises by priority — useful starting point that the deal team then edits based on current deal status.
The 5-Step Cowork IC Memo Workflow
The Cowork Deal Memo Production Workflow
Load source documents into the deal canvas
Upload CIM (or management presentation), LTM financial model export, due diligence tracker (with findings populated), and any executed term sheet or LOI. 4-5 documents is the standard load for a first-draft IC memo.
Run the transaction overview prompt
Extract deal structure, consideration, timeline, and use of proceeds. This section requires the least judgment and the Cowork output is typically 90%+ final-ready. Review for accuracy and update any numbers from the most recent correspondence.
Run business description and financial summary prompts
These are the most document-intensive sections. Run them sequentially — business description first (extracts from CIM), then financial summary (extracts from the model and management accounts). Review for current accuracy against actual deal numbers.
Run investment thesis and key risks prompts
Investment thesis draws on the full canvas context — CIM, sector research, and deal structure. Key risks pulls from the due diligence tracker if loaded. These sections require the most VP/senior banker editing but the structural first draft is complete.
Assemble and review
Combine all section outputs into the IC memo template. Senior banker reviews each section, applies judgment edits, adds client context, and refines the investment thesis. Total elapsed time from Cowork output to senior review: 60-90 minutes vs 4-5 hours from scratch.
IC Memo Prompt Templates
Prompt: Investment Thesis SectionThe most effective teams using Cowork for deal memos run these prompts sequentially within a single deal canvas that has been loaded with all the relevant source documents. The context continuity across prompts — Cowork remembers the CIM content when writing the risks section, even if that prompt was run 30 minutes after the business description prompt — is what makes the output coherent rather than disjointed.
For teams also using the Cowork due diligence workflow, the due diligence tracker with populated findings can be loaded into the same deal canvas. The risks and open items sections of the IC memo then draw directly from the structured diligence output, creating a coherent thread from data room review through to IC presentation. See the analyst shortcuts guide for additional time-saving techniques at the individual workflow level.
