Secure, open source data room for modern dealmakers

Papermark

What it does

Papermark is a secure, open-source data room platform designed for sharing confidential documents during deals. It provides granular control, visibility, and trust for modern dealmakers. Key features include whitelabeling with custom domains, built-in analytics, advanced security controls (SSO, granular permissions, dynamic watermarking, NDA gating, audit logs, IP allow-listing, end-to-end encryption), and the option to self-host. The platform supports use cases such as M&A, investment management, due diligence, fundraising, portfolio management, and real estate transactions.

Who it is for

Papermark is built for dealmakers, founders, and finance teams. It is trusted by over 60,000 global companies, including Lincoln Property Company (real estate, $50B AUM), Tesi (Finnish state investment firm, ~€2B AUM), Thesis (venture studio, $1.4B), Play Ventures (Singapore-based VC, $300M), and others. Customer testimonials highlight its use by SVP of Finance at Yuno, Investor Relations at Fabric VC, and Co-Founder of Backtrace Capital (closed €50M Fund I using Papermark).

Why it matters

Papermark addresses the need for secure, customizable, and transparent document sharing in high-stakes transactions. Its open-source nature allows for self-hosting, giving organizations full control over their data. The platform provides detailed analytics on document engagement (e.g., view duration, completion, last viewed per visitor), helping deal teams understand which pages drive decisions. Security certifications include SOC 2 Type II, ISO 27001, GDPR, HIPAA, and CCPA compliance.

Launch signal

Papermark has gained significant traction with 60,000+ global companies and a 4.9/5.0 rating on G2 and Product Hunt. It has published customer stories from Icebreaker, G.P. Loree & Co., and Backtrace Capital. The company also offers a new "Papermark for agents" feature with MCP server and API, indicating ongoing product expansion.

Brand and naming

The name "Papermark" combines "paper" (documents) and "mark" (a sign or target), evoking the concept of marking or securing documents. It is short, memorable, and the .com domain is available, enhancing credibility. The tagline clearly positions it as a secure, open-source data room for dealmakers, but the name itself does not directly convey "data room" or "security", relying on the tagline for context. Overall, it is a strong, distinctive name with good memorability and clear positioning when paired with the tagline.
