> what are some problems companies in Europe would have to deal with? What liberties are exclusive to the US?
1. Market
US: a rather unified single English-speaking market of 300 million people.
EU: 27 different markets in the EU + half a dozen markets in countries freely associated with the EU (e.g. Norway and Switzerland) in different languages, cultures and expectations
2. Money
US: unlimited unchecked runaway money. All the "unicorns" we keep hearing about can easily lose hundreds of millions and even billions dollars a year for decades, and still considered a success
EU: less money, and you are expected to actually turn a profit at some point
I don't think that the 27+ EU markets are a problem. I'm not even sure if there are 27+ different markets in the EU in the context of startups/tech, because if there were then each country would have their own isolated tech ecosystem which is not the case. Most EU countries are dominated by US tech companies.
If different cultures and languages are not a problem for US startups in spreading to Europe I fail to see why it would be a problem for EU companies
US startups <<grow>> in the US, the huge single market with a single language, then once they're big and can tackle the bureaucracy in order to get to the huge chunks of cash also available in Europe, they <<move>> into the EU.
A not-so-huge startup by US standards can have hundreds of millions of dollars very early in its life, allowing it to switch to international expansion, while most of the equivalent EU startup would probably raise tens of millions by the same stage, if they're lucky.

That's understating the issue. There are only 5 (!) EU member states with a population higher than that of the NYC metropolitan area and _none_ with that kind of population concentration or purchasing power.
> half a dozen markets in countries freely associated with the EU (e.g. Norway and Switzerland) in different languages, cultures and expectations
Well, it isn't half a dozen, it's more like 3 countries (Iceland, Switzerland and Norway). 4 if you count Liechtenstein with its population of 38k people.
