Did you receive an invoice from Theano GmbH and want to make sure the bank account listed on the invoice really belongs to Theano? You can now do this for free by using Bellin's "GTB Hub" App: 1. Install the app 2. at the bottom of the screen, hit "Verification" 3. Enter Theano's VAT ID number (can be found on the invoice and in our imprint) 4. enter the IBAN or account number you want to check. Bellin's app then shows whether we really have registered this bank account with Bellin.
