Papermark is a secure virtual data room and document sharing platform for confidential documents in fundraising, M&A, and due diligence. It tracks page-by-page viewer engagement, applies dynamic watermarking (viewer email, IP, timestamp), blocks screenshots, gates access behind one-click NDAs, and logs every action in an append-only audit trail. Its AI data room assistant lets you chat with a data room and get cited answers, plus AI-powered redaction to automatically mask sensitive information before sharing.
