Last time I have done a small survey on the location of YC companies. This time I survey a much larger database CrunchBase. CrunchBase is a database of database of technology companies, people, and investors.
Silicon Valley companies are featured prominently in CrunchBase. Again San Francisco has a commanding lead in the number of companies among Bay Area cities. My bet is most of these are small startup companies. There aren't really huge company like Cisco (14,000 Bay Area employee in 2005).
These are the numbers outside of San Francisco Bay Area. New York is the clear lead in this case.
Although without a dominant city, these state has large number of tech companies. I aggregate the number until it exceed 100 companies.
And finally some international figures. CrunchBase probably does not have very good coverage here. China is totally off the radar screen. So is Israel.
Below is everything in one chart. Bear in mind CrunchBase is likely to have some local bias and that the number does not indicate the size of the company. Still it is impressive to see San Francisco has twice as many tech companies has Germany.
