There are many small European startups who do not have infrastructure to take on large European multinationals as clients. A lot of EU labor laws have hard requirements at 50 and 100 employees so startups stay below those lines and remain tech lifestyle companies.
Now up to 24 official languages and still potentially growing in the future (although this is a bit of an overcount because some of them are mutually intelligible to various degrees, it's still a lot).
It's interesting to think that at the time of original ECSC treaty there were only four languages (French, German, Dutch and Italian). That's just about manageable, now it is a bit of an issue
We have it, and it's been growing consistently.
What we lack is risk appetite, young people dreaming to be entrepreneurs, talent, a truly unified market, regulations and proper corporate law. Say what you want but stock options essentially don't exist in Europe, so you either give equity upfront or you don't at all.
E.g. why eu has some laws in terms of data and privacy, local laws take precedence (unlike in e.g. agriculture that it's entirely EU's business). Scaling across borders is expensive and difficult for regulatory reasons.
The capital is locked up in traditional large multinationals. I've watched them launch one boondoggle after another. And it fail because of endless meetings and fearing to know their customers.
