where (online) can I find a list of the 150 largest Tech companies in SF Bay Area??

Question

I'm developing a report and am trying to identify the largest Tech Companies. Could include corps with large HQ's not located in the Bay Area, but with a substantial presence in Bay Area (ex Phillips).

Answer 1

Chamber of commerce info shows the largesst businesses in general for SF- you could go through and isolate the tech businesses out of those, but there would not be 150.
Here's a link anyway- http://www.sfchamber.com/

What I would probably do is call or email the SF public library with your question. Usually most big libraries have a research librarian that could help you find the answer. Here is a link to the web page
