Geography still matters for startups – i.e. the density (of smart, like-minded people) and walkability.
Cities with a walkable downtown, like Boston, Austin TX, and Santa Monica (not LA) are well positioned for startup ecosystem: Graduates, startup founders, and VCs are always bumping into each other or can walk up a short distance to take meetings.
So many cities are trying to create their own version of “Silicon X” – to do so, walkability might be one of the most important factors to consider and implement.
