Setting up a financial operation globally simply isn't a matter of spinning up some AWS instances and hiring a firm to do internationalization of your site.
Of course it is difficult. But claiming that you created the "credit card for the new century" is a pretty bold statement. Especially if you aren't ;-)
On the other hand I understand that saying "We slightly improved a 40-years old tool that is being replaced by totally different ideas and we are releasing it in what 10 years ago was the main market in the world, but today is only a part of the bigger picture and will be even less in the near future" sounds slightly less sexy.
^ This right here. Setting up a financial operation that's compliant and secure in the US is a bear. Adding intl is a great way to kill a thing before it's even alive.
