Series A funds and their counsel
Data rooms for a Series A
A Series A lead brings lawyers, a request list and an investment committee. The data room becomes the record of the round.
For most companies the Series A is the first time an outside law firm works through every corporate record. Expect requests on board minutes, option grants and 409A valuations, material contracts, data protection, employment and tax.
Commercial diligence goes deeper too: cohort revenue, unit economics, pipeline quality and customer calls. A clean index and a Q&A module with assigned owners turn a six-week diligence into a two-week one.
What matters most: This is the first lawyer-led diligence; Q&A with owners, redaction of customer data and a clean activity record matter more than at seed.

Step by step
How to run the room
- Match the lead's request listAsk for counsel's list early and use its numbering for your folders.
- Give counsel their own groupLawyers need legal and equity folders in full; the partner team needs metrics and contracts.
- Redact before you uploadRemove customer personal data and salaries in the room, not in copies.
- Keep the room after closingThe Series B starts with the same index; update it each quarter.
Avoid
Common mistakes
- Missing board consents for past option grants.
- Revenue in the model that does not tie to invoices.
- Answering legal questions by email outside the record.
Series A data room FAQ
What is in a Series A data room?
Corporate records, the full equity history with 409A reports, monthly financials and the model, top customer contracts, IP and privacy documents and key employment agreements. Our checklist filters the list for Series A.
How long does Series A due diligence take?
Usually three to six weeks from term sheet to close. Missing consents and unclear equity records cause most delays.
Do Series A investors care which data room you use?
Not by brand. They care that files are easy to find, that access is controlled and that questions have a clear answer trail.
