Runs structured diligence on an investment or acquisition target across four workstreams - commercial, financial, technical, and legal - and produces a red-flag register split into deal-killers versus manageable risks with a go/no-go recommendation. Use when someone asks "what should I check before investing", "run diligence on this company", "is this deal clean", or is preparing to wire money into a startup or acquisition. Do NOT use for decoding the clauses of a term sheet - use term-sheet-explainer instead; for negotiating terms, use term-sheet-negotiation; for building the target's data room from the company side, use data-room-builder.

# Due Diligence Checklist

Diligence exists to disconfirm the thesis, not confirm it: find the reason not to invest before the money moves. The costly mistake it prevents is confirmation bias - founders are persuasive, decks are polished, and the investor who only looks for supporting evidence reliably finds it. Enter assuming the deal is flawed and go hunting for the flaw; diligence is where skepticism is earned.

## Operating procedure

Run the four workstreams in this order. Commercial comes first because a broken market thesis makes the other three moot; legal comes last because its landmines are cheapest to check once the deal still looks alive.

### Step 1: Gather inputs

Collect before starting, and label every unverified founder claim as a claim:

1. The written investment thesis - one paragraph stating why this deal wins. Every finding gets tied back to it.
2. The data room or document set: financials, bank statements, cap table, material contracts, customer list.
