Data room prep — fundraise, audit, and M&A with Claude Cowork

TL;DR. Assemble a structured, complete, well-named data room for a transaction — fundraise, M&A, audit — without the founder or CFO doing it manually at midnight. 2–4 days of CFO time per data room saved. The gaps memo is the deliverable that earns trust with counsel and bankers.

Job to be done#

Populate the deal-specific data room checklist from source material spread across drives, email, and finance systems. Track status, surface gaps explicitly.

Who runs it#

CFO, GC, founder, or transaction lead.

Inputs (inbox/)#

• The deal-specific data room checklist
• Source material across drives, email, finance systems
• A naming/structure convention from the deal team or counsel

Outputs (output/)#

• A populated /output/dataroom/ folder structure
• data-room-status.xlsx — one row per checklist item, status, source, last updated
• gaps-memo.docx — items still missing, with proposed sources

Prompt seed#

Read /inbox/checklist.xlsx (the data room checklist) and the source
folders listed in /CLAUDE.md/source-folders.
For each checklist item, find the source document.
Place a renamed copy (per /CLAUDE.md/naming) into /output/dataroom/[section]/.
Update /output/data-room-status.xlsx with status per item
(Complete / Missing / Unclear).
For Missing or Unclear, list a proposed source in /output/gaps-memo.docx.
Plan first. Never modify originals.

Quality bar#

• Originals untouched; copies in the data room.
• Naming convention strictly enforced.
• Unclear is honest — do not mark as Complete on inference.
• Common trip-up: stale versions. Always pull the latest available; flag if a source folder has multiple plausible versions.

Time saved (typical)#

2–4 days of CFO or founder time per data room.

Upgrade path#

• Connector to the document warehouse and accounting system.
• A dataroom-refresh skill that runs nightly during a live deal.

Tinkso's take#

The gaps memo is the deliverable that earns trust with counsel and bankers. Most teams produce the data room and stop; producing the explicit list of gaps with proposed sources accelerates the back-and-forth dramatically. By the third gaps memo, counsel is forwarding it to junior associates instead of asking the CFO follow-up questions.
