Bulk add, and emails reborn

New

• Bulk-add companies from a CSV or Excel file — from a workspace or the add-company view.
• The Billing V2 subscription module.
• Upload a whole folder at once.
• Every transactional email rebuilt on React Email and Resend.
• A jobs list interface with filters.

Improved

• Invitations consolidated into one flow.
• The company validation dialog shows member emails, and lets you remove recipients.
• Persons display as first name + surname by default.
• A negative allocable pool is highlighted in the cap table.
• Shareholding and person data get separate cards; shareholder downloads move into one menu.
• An alert when deleting a variable that other drafts use.
