solarisBank’s vision could be summed up in two words — regulation and modularity. The company is a fully licensed bank, which means that its clients don’t have to apply to a banking license themselves. And the startup lets you pick the modules that you want to use for your product. Maybe you’re building a mobile cryptocurrency wallet and you just want to be able to give an IBAN and a debit card to your users. Maybe you’re building a used car marketplace like CarNext and you want to offer credit. Maybe you want to build a challenger bank but address a specific vertical. With solarisBank, you can open bank accounts and issue payment cards attached to those accounts. You can also issue cards and attach them to a different account in case you’re integrating with existing bank accounts.
