Thanks to bLink from SIX, mutliple banks in switzerland now supports multibanking, basically pulling transactions from other banks. I had a quick look from post finance and it can indeed link to UBS to download transactions. However, wise/revolut is not on the list.
From SIX website above, I see that bluebudget and Liquid are two fintech companies that will also support multibanking. I wonder if anyone has used them? And from there would it be possible to connect to both swiss banks (post finance, UBS, Raiffeisen ) and wise/revolut ?
