Start with Splitit — highest vibe code, weakest moat.
Airwallex
Airwallex is a regulated financial institution providing direct access to SWIFT, local clearing networks, multi-currency IBAN provisioning, and Visa/Mastercard card issuing. While an AI agent can build a frontend dashboard or an internal double-entry ledger in a weekend, it cannot replace money transmitter licenses, wholesale FX liquidity lines, or central bank clearing integrations.

- Internal multi-currency balance dashboard
- Basic double-entry ledger for internal record keeping
- Transaction tagging and expense categorization UI
- Custom invoice generation with multi-currency payment instructions
- Internal approval workflows for payout requests

Splitit
Building a script to charge a stored payment token every 30 days is straightforward. However, replicating Splitit's core model—holding total purchase amounts against existing credit limits and re-authorizing them without triggering fraud blocks—requires specialized acquirer integration and strict regulatory compliance.
