As a European, I think the largest problem is the language barrier: at the very least you need to translate everything, and then be able to answer customers requests. Not being able to talk directly to your customers is a gigantic issue, suddenly you are adding an extra indirection layer. Regarding my startup : ShiningPanda, you will definitely be able to use it from any country in the world, but I strongly doubt it will talk to you in dutch any time soon. Most certainly French, maybe Japanese (though I doubt there are enough opportunities for what we are doing there), but that's about it. Not that we don't want our service to be translated in other languages, but it would take ressources that we don't have (yet).
