Interesting article, thank you.
I don't if it is still the case, but accommodation - business and domestic - was much cheaper in Berlin than in London, with people in the creative and cultural industries choosing to live in Berlin and travel to London when they needed to.
Yes Berlin is def cheaper to operate out of, and Berlin is attracting a start ups, but London has the finance, although is still woefully short of Silicon Valley in terms of risk and failure acceptance. London investing are too conservative, I don't know if that's true for Berlin.
The UK has a different culture about entrepreneurialsim, it wants every start up to be successful, first time, rather than an iterative approach.
nailed it!
thanks for your valuable complement
