We actually have an idea in an area which is - if I read posts on HN - pretty well funded. VCs and Angles have a lot of interest. But in Germany, people don't see it - the ones with money even less. And its really hard to start a business, as you already summed up.
We even think about moving to the US, but as a foreigner it's also not "easy" (well, noone said it would be easy to start something on your own - but you get what I mean)
Almost all the promising startups in Vienna move to London, either entirely or moving the HQ and maintaining only a development office back home. I wonder if hiring good developers is easier/cheaper in mainland Europe than in the tech centres where there seems to be a shortage right now.
