What goes in a Series A data room

A data room doesn’t win a round. A bad one can cost you a week, a lead investor or a point of valuation. The good news is that investors ask for the same 60 to 90 documents almost every time. Build the room before your first meeting, and diligence takes weeks instead of months.

Here is the structure I use. The last one I built, for a Series A in early 2026, held 84 documents.

The folders

1. Company. Certificate of incorporation, bylaws, board minutes and written consents, and a current org chart.

2. Cap table and equity. A fully diluted cap table, every SAFE and convertible note, the option plan with all grants, and your most recent 409A valuation.

3. Financials. Monthly P&L, balance sheet and cash flow for the last 24 to 36 months. Your latest tax returns. Any audit or review reports.

4. Metrics. A monthly revenue or ARR bridge (new, expansion, contraction, churn), cohort retention, how gross margin is built up, and CAC and payback if you track them. Put a one-page definitions sheet at the front.

5. Model and plan. An 18- to 24-month model with three scenarios, a hiring plan and the use of funds.

6. Customers. Your top 20 customers by revenue (anonymized if you need to), sample contracts and the current pipeline.

7. Legal and IP. Material contracts, signed IP assignments for every founder, employee and contractor, and anything related to disputes.

8. People. A list of employees with roles, start dates and pay bands, your offer letter template and contractor agreements.

9. Product and security. An architecture overview, your security and privacy policies, and the status of any certification such as SOC 2.

Three things that slow deals down

Metrics that don’t tie to source. If your deck says $4.6m of ARR and your billing system says $4.1m, an analyst will find it in the first week. Reconcile every number in the deck to a document in the room before anyone sees it. If there’s a difference, explain it in writing.

Missing IP assignments. Every founder, employee and contractor who worked on the product needs one. Chasing a former contractor for a signature during diligence is slow and stressful. Do it now.

A messy cap table. Unconverted SAFEs, options promised by email, grants without board approval. Each one takes your lawyer and a board consent to fix. Start early.

How to run it

• Number everything. Keep an index at the top of the room. Investors will ask about “3.4” instead of “the cohort file, the newer one”.

• Use two levels of access. After a first meeting, share the deck, the metrics summary and the model summary. Open the full room once you have a term sheet or a serious second meeting.

• Keep a Q&A tracker. Question, who asked, owner, date, answer and a link to the document. It stops you answering the same question three times.

• Date your file names, for example “2026-05 Monthly P&L”. It ends the “is this the latest?” emails.

• Watch the activity. Most data room tools show who opened what. An investor reading your contracts on a Sunday is telling you something.

When to start

Start eight weeks before your first investor meeting. Most of the work is collecting documents you already have and fixing the few that are wrong. That’s far easier on a quiet Tuesday than with a term sheet on the table.
