Investor Data Room Checklist: Exactly What to Include for Seed Through Series B

An investor data room holds the documents a venture investor's counsel will ask for once the partner meeting goes well: the corporate record, the cap table and everything that authorizes it, IP assignments, key contracts, financials, and the prior round's executed paper. Plan for roughly 40 documents at seed, 65 at Series A and 90 at Series B. Those counts are our own rule of thumb from the rooms we have seen rather than a survey of anything, and every document count in this article should be read that way. The difference between stages is mostly financial history and commercial contracts, because the corporate set is the same set at every stage. It is simply supposed to be complete and signed.

That last clause is where rounds actually stall, and it is why this article is organized the way it is. A round does not die because a checklist item was missing. It dies because an associate found an option grant approved by email in week four, and the fix needed a board to sign something, and the term sheet had an expiry on it. So the list below is followed by the failure modes: which items break, how a diligence lawyer finds the break, and what the break costs you in calendar time.

The list by stage

Seed, roughly 40 documents

1. Corporate
   • Certificate of incorporation and every amendment
   • Bylaws
   • Board consents and minutes since formation, signed
   • Stockholder consents where the charter or statute required one
   • EIN letter and a current certificate of good standing
   • Foreign qualification in every state where you have employees
2. Cap table and equity
   • Cap table as a spreadsheet, tied line by line to the stock ledger
   • Founder stock purchase agreements
   • Founder vesting agreements, including any acceleration terms
   • 83(b) elections with proof of timely filing
   • Equity incentive plan, with the board and stockholder approvals that adopted it
   • Option grant ledger with grant dates, exercise prices and the approval for each
   • Every SAFE and convertible note, with every side letter
3. Intellectual property
   • Confidential information and invention assignment agreements for every founder, employee and contractor
   • Trademark and patent filings, with status
   • Domain list and any material inbound licenses
   • Open source policy if you ship software
4. Commercial
   • Template customer agreement
   • Signed contracts for your largest customers
   • A note flagging any exclusivity, most favored nation or change of control term
5. Financial

   • Insurance certificates
   • Any litigation, threatened or pending
   • Privacy policy, terms of service, and a note on what personal data you hold

Series A adds, roughly 65 total

• The seed round's executed paper: stock purchase agreement, investors' rights agreement, voting agreement, right of first refusal and co-sale agreement, and the amended and restated charter
• Board minutes and consents for every meeting since that closing, signed
• A current 409A valuation report
• Option ledger reconciled to the plan reserve, showing what is granted, exercised, outstanding and available
• Customer concentration and cohort retention
• Key contracts marked for assignment and change of control terms
• Security questionnaire answers and a subprocessor list
• Data processing terms if you handle personal data
• Employee census with compensation bands rather than individual salaries

Series B adds, roughly 90 total

• Reviewed or audited financials, with your revenue recognition policy
• Monthly cohort data, churn and net revenue retention with the definitions you use
• Sales compensation plans and quota attainment
• Pipeline by stage, with each stage defined
• Subsidiary formation documents and intercompany agreements
• International entities, payroll arrangements and contractor classification analysis
• Tax filings and any state nexus analysis
• Insurance schedule including directors and officers coverage
• Material vendor contracts and an open source inventory

What actually breaks, and what it costs you

These are the findings that turn a two-week confirmatory diligence into a six-week one. Each is cheap to fix in advance and expensive to fix under a signed term sheet.

Board consents that were approved but never signed. Every option grant, every stock issuance, every charter amendment needs an authorizing consent with signatures on it. Approval in a meeting somebody remembers is not the record. The fix is a ratifying consent, which is straightforward, but counsel has to identify every gap first and your board has to sign, and that takes calendar time you will not have in week five.

A cap table that does not tie to the stock ledger. The spreadsheet and the underlying issuance documents have to agree on share counts, dates, prices and holder names. They usually diverge at the seams: a repurchase nobody recorded, a transfer to a trust, an exercise that was paid but never issued. Investors' counsel reconciles the two, and a difference of a hundred shares becomes a question about your record keeping generally.

Missing 83(b) elections. A founder who did not file within 30 days of purchase carries a tax problem that no amount of paperwork now solves. You cannot fix it in diligence. You can disclose it accurately, and you should, because the discovered version is worse than the disclosed one.

IP assignments that were never executed. The gap is almost always an early contractor, a friend who built the first prototype, or a founder who left. If the assignment was never signed, the company may not own the code or the mark. Chase these down the week you start building the room, because the counterparty is a person whose response time you do not control.

Option grants approved by email. A grant needs a board approval, an exercise price supported by a current valuation, and a signed award agreement delivered to the employee. Grants that live only in a spreadsheet, or that were priced off a stale 409A, get repriced or re-approved, and repricing is a conversation with your employees at exactly the wrong moment.

Founder vesting with acceleration nobody modeled. Single-trigger acceleration and unusual vesting schedules are fine as long as they are documented and everyone knows they exist. What is not fine is an investor's counsel finding acceleration in week four that changes the post-money cap table.

SAFEs and notes with terms nobody has stacked. Pro rata side letters, most favored nation clauses and inconsistent caps across a dozen instruments compound into a conversion nobody has modeled. Build the conversion model before the room opens, and put it in the room. The investor is going to build it anyway.

Advisor and consultant equity with no assignment language. Advisors who received equity but signed nothing assigning their work product are the same problem as the missing contractor assignment, with the added complication that they are usually still in your network.

What should you deliberately leave out?

For a fundraise the short answer is: founders' personal tax returns at any stage, individual offer letters and salary detail, source code, internal strategy memos, and board decks carrying projections you no longer believe. The full exclusion discipline, including privilege, competitively sensitive customer economics and unredacted personnel data, belongs to the sale-process version of this problem and is set out in our due diligence data room checklist.

The founder-specific reason to hold things back is worth one line of its own. Every document in the room is a document an investor's counsel can ask about, and the question arrives on their schedule rather than yours.

When do you open the room?

Not with the first email. The deck earns the meeting, and the room answers the questions the meeting produced.

Before the raise: build the room and share it with nobody. This is when you find the unsigned consent and the missing election, and this is when fixing them costs two weeks instead of the timetable.

After the first partner meeting, or when an investor asks: share a scoped view covering corporate, cap table, financials and the metrics you already presented.

After a term sheet: open the full set for confirmatory diligence.

Two tiers, one room. Send each investor their own link scoped to what they should see, rather than one link that circulates. Per-recipient links are also how you find out later who actually read what, which matters more than founders expect. If you are still deciding what to run the room on, what a virtual data room actually is covers the category, and when a shared drive is and is not enough covers the option most seed founders start with.

How do you keep the room current across a three-month raise?

A room built once and never touched goes stale in about three weeks, usually at the financials.

One owner, one weekly pass. Financials refresh monthly, the cap table refreshes on every issuance, and the metrics refresh whenever you send an update.

Replace, do not append. A folder holding model v3, model v3 final and model v3 final revised is a question you will get asked. Replace the file and let the index carry one current version.

Name what does not exist. If an investor asks for something you do not have, add a line to the index naming the document, saying plainly that it does not exist yet, and giving the date it will. An acknowledged gap reads as a project plan. A silent gap discovered in week six reads as a reason to ask what else is missing.

Watch engagement and act on it. If a partner opened the model twice and never opened the customer contracts, your follow-up email writes itself.

Close the room when the round closes. Revoke the links. A room left open after a closing is a document set circulating without a reason.

How Mage handles the readiness list

Mage Data Room ships a fundraising readiness checklist: the documents a venture investor's counsel requests in a financing, scored per item as present, partial, missing or not applicable. The verdict is computed against your room's actual inventory rather than against a static template, and any curation you do by hand, marking an item complete or not applicable, survives every recompute.

Two details make that list usable rather than decorative. Amendments, exhibits and side letters are linked to the agreement they belong to, so a SAFE side letter stops living three folders away from the SAFE and stops reading as a missing item when it is really a filed one. And an item you mark not applicable, because you have no subsidiaries or no option plan yet, stays not applicable through every recompute rather than reappearing as a gap the next time something uploads.

If you work with an AI agent, hand it the list rather than the folder. npx @magelegal/cli readiness --json returns every checklist item with its status and an id, and npx @magelegal/cli upload <file> --for-item <itemId> files a document against the item it satisfies, so the agent can work the missing list until nothing required is left. That loop is the whole reason the checklist is a data structure rather than a page. Mage is SOC 2 Type II certified, and the data room is free for a limited time and self-serve, with no lead form.
