The seed data room checklist

Build the room before your first meeting and share it in three tiers: a first look, full diligence, then the legal detail after a term sheet. The must-haves decide whether you’re ready, not the deck. In our worked example, a seed company with every first-look document done is only 48% ready, with 18 must-haves still open.

What investors actually ask for

At pre-seed, investors are deciding whether to believe you, not auditing your books. The ask is short: the deck, who you are, what the money is for, the cap table (who owns what) and proof the company owns what it built. In the Data Room Builder that’s 18 documents, 12 must-haves.

At seed, the room becomes a real diligence tool, and investors start checking the deck against the accounts. A seed equity raise needs 67 documents across 14 folders, 31 of them must-haves. Mark anything that doesn’t apply, like a loan you don’t have, as N/A and it leaves the score. The request often comes at the end of a good first meeting, so build the room before you start.

The checklist, by tier

Open a tier only when every must-have in it is ready. These are the must-haves for a seed equity raise.

Tier	When	Must-haves	Also expected
T1 · First look	After a first meeting, before any NDA (non-disclosure agreement)	Data room index, pitch deck, founder bios, use of funds, KPI dashboard (12–24 months, monthly), metric definitions	One-pager, overview memo, product demo, org chart, market sizing, competition
T2 · Diligence	Under NDA, once an investor is serious	Certificate of incorporation, articles or bylaws, group structure, shareholder register, shareholders’ agreement, prior financing documents, fully diluted cap table, pro forma cap table, SAFE and note summary, annual accounts, monthly management accounts (24 months), 3–5 year model with assumptions, burn and runway, unit economics, licences, debt schedule, Q&A log	Investor updates, budget vs actual, cohorts, customer concentration, roadmap, hiring plan
T3 · Confirmatory	After a signed term sheet, mainly for their lawyers	Board minutes and resolutions, option plan and its approval, option grant ledger, IP assignments from founders, staff and contractors, key employee agreements, disputes schedule, loan agreements	Bank statements, revenue-to-bank reconciliation, founder vesting, advisor agreements, trademarks, privacy compliance

A SAFE (simple agreement for future equity) or a convertible note turns into shares later, so it belongs on the cap table now. At pre-seed the must-haves are the first-look pack, without metric definitions, plus the basics: incorporation documents and articles, prior financing documents, the cap table and SAFE summary, burn and runway, and the founders’ IP assignments.

What lenders ask for

Lenders price the downside: will you repay if growth slows? A seed debt raise needs 51 documents, 29 must-haves. It adds a 13-week cash flow forecast, covenant compliance certificates, lender reports and the other offers you’re discussing, and drops most of the growth story: demo, market sizing, option plan, pro forma cap table. Raising both? That’s 71 documents, 33 must-haves.

Our reading of public data as of October 2026: lenders want monthly accounts and KPIs for the last 24–36 months, receivables and payables ageing, a model with a downside case and a list of existing debt and security. They also look for 12–18 months of runway. When offers arrive, see how to compare debt offers.

How readiness is scored

Each document counts by how much investors need it and how far along it is:

Readiness = sum of (weight × status) ÷ sum of weights

Weight: must-have 3, should-have 2, nice-to-have 1. Status: ready 1, started ½, to do 0. N/A leaves the sum. The room is ready to open only when every must-have is ready, no high red flag is open and every red-flag question is answered.

T1 First look100%

T2 Diligence50%

T3 Confirmatory14%

All documents48%

The example company, a seed equity raise. The first look is ready to share; diligence has 11 of 17 must-haves open and confirmatory 7 of 8. That’s 77.5 of 162 weighted points: 48%, with 13 of 31 must-haves and 26 of 67 documents ready.

Red flags that slow a round

The Data Room Builder asks 21 questions, 9 of them high severity. The example fails two: its cap table doesn’t match the share register, and its revenue doesn’t reconcile to bank receipts. The ones that most often stall a seed round:

A cap table that doesn’t reconcile. It must match the share register and every signed SAFE, note, option and warrant, to the share. Investors’ lawyers check it first.
Missing approvals. A share issue or option grant with no board or shareholder resolution may need ratifying (approving after the fact) before closing.
Rights and promises nobody wrote down. Side letters, pro-rata rights (to invest again and keep a share) and verbal equity promises to advisors. They surface late and can reprice the round.
Missing IP assignments. Founders, staff and contractors must have signed over what they built, including work from before the company existed.
Numbers that don’t match. Revenue against bank receipts, the model’s past months against the management accounts, the deck against both. One mismatch costs more trust than a missing file.
Licences and disputes. Trading without a licence you need, or a claim investors find before you mention it. A disputes schedule that says “none” still belongs in the room.

Law firms flag the same problems, plus out-of-date company records and drafts mixed with signed contracts.

How long it takes

Our reading of public data as of October 2026 (sources below). Use it as a sense check, not a promise.

Step	Typical time
Assemble it, if the documents exist	3–6 hours of focused work
Build it from scratch	Ten working days on the Data Room Builder’s plan, one area a day
Fix the red flags	Often longer than building the room: you wait on other people’s signatures
When to start	6–8 weeks before you open the round
Equity: diligence and documents after the term sheet	3–4 weeks if nothing comes up, 6–7 on a longer timeline
Venture debt: to close	4–8 weeks; 2–3 just after an equity round

Before you share

The index matches the room. Everything is listed and named one way: reference, name, date, like “04.02 Management accounts - 2026-09”.
The tier is complete. Every must-have in it is ready and every red flag has an answer. Signed copies only; keep drafts out.
The numbers match everywhere. Revenue, cash, burn, headcount and shares issued agree across the deck, model, accounts and cap table, or the difference is labelled.
Access follows the tiers. Keep an access log and NDA register, make diligence documents view-only and watermarked where you can, and give confirmatory access to the lawyers. Remove access the day talks end.
One Q&A log. The same answer to every investor, within two working days.

Build your own room

The Data Room Builder does this for your stage and raise, free: the checklist, red flags, a numbers check and a live readiness score. Pro, a one-off $49, adds which tier you can open, a 10-day plan with your open documents, a folder template to upload, a folder check that ticks off what you have (file names only, never the files), 54 diligence questions mapped to your documents, and Excel and PDF. All three tools are $99.
