Seed data room checklist: what to put in it and when to share it

• Send the deck with outreach; open the data room only after real interest.
• Use two layers: an 'interested' folder after a meeting and a full diligence folder for your lead.
• Investors check founder vesting, 83(b) elections, IP assignment and a cap table that matches signed documents.
• Healthcare, fintech, hardware and climate founders need a regulatory folder from day one.
• Keep one Q&A log so you answer each diligence question once.
• Disclose problems in the read-me; surprises cost more than the problem itself.

What a seed data room is (and when to open it)

A data room is a shared folder where an investor can check everything you said in the pitch. At pre-seed it can be a dozen files. At seed it's usually 30 to 60. Either way, its job is the same: let a serious investor say yes without waiting a week for you to dig up a contract.

Don't send the full data room with your outreach email. Send the deck. Open the data room once an investor has taken a meeting and asked for more, or once a lead is working toward a term sheet. Sharing everything up front invites questions you haven't framed yet and makes it hard to see who is truly interested.

A useful way to think about it is two layers:

• Layer 1, the "interested" folder: deck, one-pager, a short financial model, a metrics snapshot and a cap table summary. Share after a good meeting.
• Layer 2, the diligence folder: legal documents, contracts, full financials, IP and employment records. Share with your lead and anyone who asks to confirm a commitment.

The seed data room checklist

Use this table as your build list. "Pre-seed" means a small round from angels, an angel group or a micro-VC. "Seed" means a priced or larger SAFE round with a lead who will run real diligence.

A folder structure you can copy

Numbered folders keep the order the same on every screen. Name files so they sort and explain themselves.

10_Q&A_log.pdf             (every diligence question and your answer)

The read-me page is small and does a lot. It tells the investor the date the room was last updated, which numbers are audited or reviewed and which are management numbers, and the one person to email with questions. For a fuller index you can paste into a doc, use the data room index template.

The legal basics investors check most

Most seed diligence problems are boring and fixable, as long as you find them before the investor does:

• Founder vesting and 83(b) elections. If founders bought restricted stock, the IRS says an 83(b) election must be filed no later than 30 days after the property was transferred. Keep a copy of each filed election and proof of mailing. A missing 83(b) is hard to fix later, so check now.
• IP assignment. Every person who wrote code, designed the product or contributed ideas should have signed an invention assignment to the company. Pre-incorporation work needs an assignment too.
• Clean cap table. Every SAFE, note and promised percentage in writing, with a cap table that reconciles to the signed documents. Verbal promises of equity are a red flag.
• Prior Form D filings. If you've already sold securities under Regulation D, the SEC requires a Form D notice within 15 days after your date of first sale. Investors may ask whether earlier rounds were filed. See Form D.

Sector extras: healthcare, fintech, hardware and climate

Founders outside the usual software playbook often get slowed down by sector diligence they didn't expect. Add a folder for it:

• Healthcare and digital health: regulatory pathway memo (for example, whether the product is a medical device), privacy and security approach for patient data, business associate agreements, clinical evidence and pilot results.
• Fintech: licensing approach, partner bank or sponsor agreements, compliance policies and any regulator correspondence.
• Manufacturing and hardware: bill of materials and unit cost, supplier and contract manufacturer agreements, certifications, warranty assumptions.
• Climate and energy: permits, interconnection or offtake agreements, grant awards and their conditions, and the assumptions behind any emissions figures.

The one page investors read most: your metrics

Whatever else is in the room, the metrics file gets the most attention. Make it a single page or sheet with a definition beside every number. A simple layout (with hypothetical values):

Use the same definitions in the deck, the model and every update. Mismatched numbers cause more diligence delays than any missing document.

Access, permissions and tracking

Any tool works if it lets you give view-only access by person and see who opened what. A shared drive folder is fine at pre-seed. At seed, many founders move to a data room tool with per-investor links and download controls.

• Give each firm its own access so you can revoke it later.
• Watermark or disable downloads for contracts and financials if that matters to you.
• Watch activity. An investor who spends an hour in the cap table folder is doing real work. One who never opens the link is not.
• Log every question in a single Q&A document. Answer once, reuse often.

Red flags to fix before you share

None of these kill a round on their own. Hiding them does. Investors outside the big hubs often invest smaller amounts and do lighter diligence, but they talk to each other, and a clean data room travels with your reputation from one angel group to the next.

Your next step

Block two afternoons. Use one to build Layer 1 and the other to list the gaps in Layer 2. Then send the gap list to your lawyer, since most fixes take days, not hours. While that's happening, line up the investors who will actually read the room: Zalarma has 8,652 US startup investor records that list pre-seed and 19,738 that list seed, filterable by sector, check size and state.
