But I think the question for Hacker News, or at least for the Hackers who are interested in doing startups outside the USA is-- what's the international Delaware?
What's the place to domicile your business, with reasonable laws and taxes?
Some possibilities I can think of: Hong Kong, Singapore, Cyprus and some of the UK islands like the Isle of Mann might be good.
I love Berlin. It is a happening city, and I'm very happy to spend time there. It has a very nice mix of cutting edge modernism and the former east german sections which are still relatively inexpensive. And I just like germans.
I think startups can group employees wherever makes sense for their workforce. If its all EU people then berlin might be ideal. But the business doesn't have to be a german business. (Or does it?)
Edit to add: Obviously I'm writing this from the perspective of a self-started or bootstrapped business. This perspective isn't likely to be appropriate for people who plan to take outside investment.
