A data room for due diligence and M&A, for a small company

Updated November 2, 2026. By Vela Partners.

A small company can run due diligence or a sell-side M&A process in ArtifactSend for free. You get a free data room with NDA and watermark, folders, verified buyers, Q and A, and a record of which buyer read which document.

The short answer

You do not need Datasite or Intralinks for a small deal. ArtifactSend data rooms are free, hold up to 300 documents each, and have what a buyer's diligence team expects. That means folders, an NDA accepted before viewing, a watermark with each reader's email, downloads off by default, and Q and A.

You see which buyer opened which document and for how long, so you know who is serious before the next call.

When to pay for an enterprise room

Pick Datasite or Intralinks for a large auction with many bidders, a legal team that requires their audit reports, or built-in redaction. For a small business sale, a startup round's diligence, or a partnership review, a free room covers it.
