DocChief AI is a document intelligence and equity governance platform for startups, their investors, and their lawyers. Upload your corporate records and DocChief reads every document: it classifies each one, extracts the parties, dates, issuances, and relationships, and builds a structured record of the company's history. The Cap Table Health Check flags gaps between your cap table and your signed documents, such as missing board consents, unsigned stock purchase agreements, or grants without approvals, before an investor finds them in diligence. Organize everything in a due diligence-ready virtual data room, share it with secure tracked links, and see who viewed what. Ask questions in plain English and get answers cited to the source page. DocChief keeps your records current between financings, so every raise, audit, or acquisition starts from a clean, verified data room instead of a scramble.
