I believe Berlin has the best shot in the Western world outside of Silicon Valley at becoming a place with a true tech startup ecosystem. I don’t just mean a place where one or two great companies are born — that can happen pretty much anywhere. I mean a place with an enduring ecosystem powered by a network effect that gets stronger over time. Like what Hollywood is for entertainment, London and New York are for big finance, Milan and Paris are for fashion, and Silicon Valley is for technology.
