Papermark is a secure, fully customizable, and developer-friendly data room for mid-market M&A. Page-by-page analytics, NDA gating, dynamic watermarking, unlimited data room visitors, and a published €99/month Data Rooms plan. No per-page quote.
No credit card required.

Datasite Diligence is built for bank-run, large-cap sell-sides with AI redaction and a page-based quote. Mid-market advisors need the same deal-room controls on a number they can put in a budget before they call sales.
Reported rates sit around $0.60 a page. A 12,000-page diligence set is $7,200 in upload charges before a bidder opens a file. Typical rooms land at $25,000+/year.
Every Datasite engagement starts with a sales call and a page-count scoping exercise. There is no trial that ends in a working M&A data room.
Datasite acquired Firmex in 2021 and Ansarada in 2024. Switching to those brands is a different SKU, not an independent vendor.
Match the core Diligence features (permissions, watermarks, Q&A, audit log) against a published monthly plan.


See which buyer spent 40 minutes in customer contracts and which one bounced after the CIM. Page-level heatmaps are on every Papermark plan, not an enterprise add-on.
One-click NDA on the link. Split first-round and confirmatory bidders into different folders of the same room without provisioning a named account for each reviewer.
Stamp each viewer's email, IP, and timestamp on every page. View-only mode, screenshot protection, and instant link revocation sit next to it.
Keep competing buyers from seeing each other's questions. Q&A ships from Data Rooms Plus, with permissions so only the deal team answers.
Datasite quotes per page, commonly around $0.60, with typical rooms at $25,000+/year. Papermark Data Rooms is a published monthly number that does not move when you upload another 4,000 pages.
Nine first-round bidders and three confirmatory ones do not change the invoice. Visitors are included on every plan. Paid seats are for your team, not for external reviewers.
Click each control. These are the Datasite Diligence capabilities mid-market teams actually need to keep.

The baseline M&A counterparties require, on a self-serve plan.
ISO 27001 certified. SOC 2 Type II from Data Rooms Plus and above. GDPR, HIPAA, and CCPA aligned.
NDA gating, dynamic watermarks, view-only mode, screenshot protection, and an exportable audit log.
Create rooms, set permissions, and read analytics programmatically. Datasite does not offer a comparable self-serve developer path.
Custom domain, your logo, Papermark branding removed. Set link permissions per bidder group and keep unlimited branded rooms on the same Data Rooms plan.
