Data Room — Definition

A data room is a secure, access-controlled space where the confidential documents involved in a transaction are stored and shared with a defined set of people. In a fundraising round, an acquisition, or a diligence process, it is where the buyer or investor reviews the material they need to make a decision.

The term predates software: a physical data room was a literal locked room of paper files that visitors reviewed under supervision. A virtual data room (VDR) moves that online — the same controlled access and audit trail, without the room.

How the term is used

• M&A — the seller populates a data room; the buyer's advisors review it during diligence.
• Fundraising — a company shares financials, contracts, and cap-table documents with prospective investors.
• Diligence generally — any process where one party must review another's confidential documents under controlled access.
