It's not the funding that is the problem.

Europeans have no need for Silicon Valley. Most of Europe is technologically conservative and averse to trying out new stuff, in a way that other audiences are not. Governments will go at great lengths to make sure that the law forbids any entrepreneurial action that threatens the status quo in just about anything. In other words, severe and chronic risk aversion from both the entrepreneurs, their audience and the regulatory environment.

Would companies like Airbnb, Uber, Facebook, Snapchat be ever able to grow if they had targeted Europeans?

How many of you european entrepreneurs here actually target primarily the European market or expect to grow in it?
