I never heard of them but browsed their website just now out of curiosity. They list an adress in the US and one in Bulgaria on https://mobisystems.com/en-us/contacts. My guess would be that it is developed in Bulgaria (so it supports people working in the EU), but sold from the US (so it they may pay their taxes there).
MobiOffice is US located according to App Store information, does anyone know more about this?
