Startup founders, venture capital associates, and corporate development executives sharing financial projections, cap tables, and pitch decks with prospective investors must deter unauthorized forwarding and protect intellectual property. Stamping a prominent semi-transparent "CONFIDENTIAL" watermark across slides asserts trade secret rights. PDFZento applies custom watermarks locally without sharing your deck.
