Field notes
The described workflow links equity changes to registers, dilution calculations, option records, and meeting preparation rather than treating each as a separate spreadsheet. Its procedure calendar surfaces overdue items, deadlines within 30 days, and future items, with legal provisions shown as the basis. The page says AI can be disabled and that each company keeps its database in an environment it manages.
