Not relative to our pricing! For a £5k transfer we're charging 83% less than Wise. I'm certainly happy to pay 83% less for substantially the same service :)

I'm a happy Wise user, they provide me an easy way to get paid by my US clients when doing contracting work and offer very quick transfers for quite cheap. If you can compete as well as you say on a pair USD-EUR I would be more than happy to try out your service.

Is there a way to get notified when you will add support for other currencies?

Depends on currency. Wise takes ~3% to transfer USD/EUR to CLP (Pesos Chilenos)

For transfer above a certain amount the .5% or whatever they charge still adds up.
