Why Purser
Agents do the work. The CFO keeps the say.
- Face ID on the exact terms
Above a limit, the CFO signs amount, payee and account. Change one cent and it fails.
- Limits in code, not prompts
Claude agents read and propose; Purser's code holds the limits.
- Rails that refuse too
Airwallex, Metal and Visa via Airi apply their own controls.
- Booked and checkable
Every payment is booked; its signed receipt checks offline.
