German law makes the "out of the garage + Angel investor" start-up culture impossible. The only possible way is to make money AND start out with a huge amount of cash. I can't speak for other Euro countries.
What part? Is the incorporation of a company complicated\bureacratic? I know here in Czech Rep you pretty much need to have a local Czech speaker setup\registered\licensed with a certain status before you can create a new company. Or is there some capital requirements ("you must have €x,000 in the company accts to operate"), or lawyers fees that make it either tough\impossible for the early "ramen" stage?
There is now a mini-GmbH, essentially a type of Ltd. that can only handle a limited (pun not intended) amount of assets, but does not require you to have enough assets to pay back the debts.
Then there are GbR, etc, a lot of nice incorporation types, but these, while effective for a normal company, are not useful for a silicon-valley type of company, as the silicon valley relies on an investment bubble - and a GbR and similar place the liability completely with the owners of the company.
Then there are consumer cooperatives and so on, but while these, again, are useful for the normal economy, you can’t use them to make profit by scamming people (as they are effectively profit-less).
