Papermark

Papermark is a secure data room and document sharing platform for dealmakers, founders and finance teams. Users upload pitch decks, financial models, contracts and other confidential files, share them through tracked links or full virtual data rooms, and see page by page analytics on who viewed what and for how long. The product is open source, and an enterprise version can be self hosted on a company's own infrastructure. It serves teams running fundraising, mergers and acquisitions, due diligence, investor relations, real estate transactions and client portals. Security controls include SSO, granular file level permissions, dynamic watermarking, NDA gating, email verification, allow and block lists, screenshot protection, audit logs, IP allow listing and end to end encryption, and the company holds ISO 27001 and SOC 2 Type II certification. Papermark AI adds a data room copilot that lets users chat with documents and create review personas, and the product line also lists AI redaction and AI agents for data rooms. Business and Data Rooms plans expose webhooks, an MCP server, an API and a CLI, and supported file types range from PDFs and Office documents to video, CAD and geographic data.
