Data Room Red Flags: The 11 Gaps That Stall Due Diligence
Diligence rarely dies from a bad answer. It dies from a missing one, discovered late, that takes three weeks and a third party to resolve.
These are the eleven gaps that most often stall an early-stage round, ranked by how expensive they are to fix once diligence has already started. The first three are the ones that actually kill deals.
Key takeaways
- Unassigned IP is, in our experience, the most common fatal gap and the most expensive to fix, because it needs signatures from people who have left.
- A cap table that does not reconcile to its own SAFEs converts a funding conversation into a cleanup conversation.
- Metrics without definitions are read as metrics being hidden.
- Most of these cost a day to fix before a raise and weeks to fix during one.
- Fix in the order below. It is sorted by cost of late discovery, not by how hard each one is.
1. IP not assigned to the company
Cost if found late: fatal or multi-week.
Every founder, employee and contractor who contributed to the product must have assigned that work to the company in writing. The gap is usually a contractor or a co-founder who left, which means the fix requires a signature from someone with no obligation to provide it and whose leverage rises the moment they learn a round depends on it.
Fix: collect signed assignments from everyone who ever touched the codebase or design. Do it before you raise. It costs a template and some emails now.
2. Cap table does not reconcile
Cost if found late: 1-3 weeks.
Unrecorded SAFEs, a handshake with an advisor that was never papered, an option pool that does not add up, a note whose cap nobody can find.
Fix: list every instrument with amount, cap, discount and date. Add the proposed round. Check the resulting ownership matches what you are telling investors. Any discrepancy is yours to resolve before they find it.
3. No vesting on founder equity
Cost if found late: 1-2 weeks and a difficult conversation.
An investor sees a company that could lose half its equity to a departed founder with no recovery mechanism. That is a live risk to the asset.
Fix: four-year vest, one-year cliff, ideally backdated to when real work began. Retrofitting after a term sheet is legally possible and interpersonally expensive.
4. Metrics without definitions
Cost: a silent pass you never hear about.
"10,000 users" is not a metric. Active how? Over what window? Counted how? Deduplicated?
The damage is invisible: the investor does not challenge it, they discount it, and you never learn that they did.
Fix: a definitions block. One line per metric stating exactly what is counted, over what period, from what source.
5. Market size with no method
Cost: caps your market score at 2.
A TAM lifted from an industry report is treated as a number with no basis, because it is.
Fix: bottom-up. Number of target companies, times realistic annual contract value, times a defensible adoption assumption. Show the arithmetic. A smaller derived number beats a larger asserted one every time.
6. Stale documents
Cost: reputational, and it compounds.
A model last touched nine months ago. A deck with last year's traction. A roadmap whose Q1 items are still listed as upcoming in November.
Staleness tells an investor about your operating cadence, and they generalise from it.
Fix: date every document in its filename. Review monthly. If a document cannot be kept current, remove it.
7. Shipped and roadmap presented as the same thing
Cost: the credibility discount applied to everything else.
Describing a planned feature in the present tense is usually accidental and always expensive. Once an investor catches one overclaim, every other claim is re-read sceptically.
Fix: an explicit table - shipped, in build, planned. Honesty here is read as competence, not as weakness.
8. No use of funds tied to milestones
Cost: caps your deal score at 3, stalls conversion.
"18 months of runway" is not a use of funds. It tells an investor what the money buys in time, not what it buys in evidence.
Fix: allocate the raise across categories, attach each to a milestone, and state what those milestones prove for the next round.
9. One giant PDF
Cost: days of investor time, spent on reassembly.
A 60-page document that contains every answer and is searchable by nobody. The investor has to read linearly to find one number.
Fix: structure by field. If you must ship documents, split them by topic with descriptive filenames.
10. No access control
Cost: variable, occasionally severe.
One link containing your cap table, sent to a hundred people, forwarded onward indefinitely. The cost is usually zero until it is not.
Fix: tiered access with expiry. Public tier for anything forwardable, due-diligence tier granted per person.
11. Missing customer evidence
Cost: 1-2 weeks of back and forth.
Traction claims with nothing behind them. No contracts, no LOIs, no usage data, no references offered.
Fix: for each material customer claim, hold one artefact: a contract, a signed LOI, a usage export, or a reference willing to take a call. Offering references before being asked is one of the strongest signals available.
The pattern
Ten of the eleven are documentation failures, not business failures. The company is fine. The record is not.
That is why this list is worth working through before a raise rather than during one. Every item costs hours now and weeks later, and weeks later is exactly when you have the least of them.
Run it as a pre-raise audit: go through all eleven, fix what is broken, then start outreach. A day spent here routinely saves a month.
Frequently Asked Questions
Unassigned IP, a cap table that does not reconcile, and no founder vesting. Those three stall or kill rounds. The rest slow them down.
Almost always a missing answer that requires a third party to resolve - a signature, a document, a reconciliation - discovered at the point it is most expensive.
Corporate existence, cap table reconciliation and IP assignment. The unglamorous items that determine whether the company owns what it says it owns.
Give the link to someone outside the company and ask them to write a one-paragraph summary of what you do, what you are raising and what the money is for. Whatever they cannot answer is your gap list.
