As (Transfer)Wise is now doing a lot more than just money transfers they’re changing their name from TransferWise to just Wise (and given their low fees you’ll sure be wise to use their services).
For existing customers not too much will change right away. You can access your account via wise.com, using your current email and password. You won’t need a new account.
The core experience of using Wise will remain faster, cheaper, and more convenient than anything else. Their mission remains the same. They’re still making — and always will be making — money work without borders.
