Papermark vs Datasite
This is a David-and-Goliath pairing. Datasite (formerly Merrill) is one of the largest enterprise VDR vendors, built for banker-run M&A with AI redaction and staffed services. Papermark is an open-source data room that starts free and publishes flat pricing.
They rarely compete for the same deal — which is exactly why the comparison is useful. The right question is not which is better in the abstract, but which matches the size and formality of your process.
Verdict
Papermark for lean deals; Datasite for banker-run M&A
For fundraising, early diligence, and most sub-$50M processes, Papermark covers the controls that matter — permissions, watermarking, audit trails, NDA gating — at a fraction of Datasite's reported ~$25,000+/year starting cost, and it is the only one of the two you can use free.
For a regulated $500M sell-side process, Datasite is the safer choice. Its AI redaction, project services, and bank-grade process tooling exist for exactly that work; Papermark's advantage is speed and cost, not enterprise deal services.
