As a european I dont believe in European anything. I worked for European scale-ups and they are all bunch of nationalists that primarily succeed in their primary country and then fail to expand in any other country because they meet the local alternative.

The best market to expand besides your own Euro-country is the US but tthen when you enter that market you are too small of a fish to do anything.

There is no such thing as european companies. It's german companies, french companies all mainly focused on their main markets.
