Maybe something is wrong in my browser, but changing the language just changes the tagline at the top, the rest of the body remains untranslated (English), except for French (founders are French) which translates the entire page.

Actually my impression is that they have done a good job of targeting the EU market and its languages without suggesting that they have any official connection to the EU. There's neither a flag nor a logo and the background blue is, to my eye at least, not the azure of the EU flag.

(Although curiously they call their background colour bg-european-blue in their CSS.)
