I don't know the legislation and contract law pertains to funding, and why EU companies need to move to the US to get investor funds (and can't be funded internationally while retaining EU status).
What I can tell you from my experience in seeking out venture/angel/seed funding opportunities in the EU is that many (most) that turn up on search results don't have a "pitch us" form and more of a "we'll find you if we want to fund you". There are also incubators, a la YCombinator, that provide only mentorship and no funding (ie. I would need to quit my job and sustain myself to build a startup).
