Papermark is a secure document sharing and data rooms infrastructure that enables you to share documents, track engagement, and protect your content with enterprise-grade security. As the #1 open-source alternative to DocSend, Papermark gives you complete control over how your documents are shared and viewed.
Papermark fits every deal. Whether you're a startup raising your next round, a VC managing fund operations, or a team running M&A due diligence, Papermark provides the tools you need to share data rooms securely while gaining valuable insights into viewer engagement.
Papermark gives you the flexibility to share a single document or organize multiple documents in a secure data room.
Papermark Data Rooms are secure online repositories for organizing, storing, and sharing multiple confidential documents in one centralized location. Unlike traditional file sharing, data rooms provide granular access controls, comprehensive audit trails, and advanced security features.
Data rooms are perfect for due diligence, fundraising, M&A transactions, legal processes, and any scenario requiring secure document collaboration.

Unlike traditional file sharing, Papermark tracks exactly how viewers engage with your documents. You can see which pages receive the most attention, how long viewers spend on each page, and where they drop off. This page-by-page analytics helps you understand what resonates with your audience and identify the most engaged prospects.

Get notified instantly when someone views your document. Papermark sends real-time email notifications so you know exactly when a prospect, investor, or client opens your content. This timing intelligence helps you follow up at the perfect moment.
Make every document feel like part of your brand. With Papermark, you can connect your custom domain (e.g., docs.yourcompany.com), add your logo, customize colors, and create a seamless branded experience for your viewers.
