<i>Most of the founders of successful Bay Area startups are not "locals", but first generation "immigrants" from other parts of the US/world.</i><p>Very true. When I started representing startups in the Valley in the mid-80's, the overwhelming majority of the founders were "locals." Since 2000 at least, this pattern has decidedly shifted, at least for the companies I represent (with a clear majority now being either immigrants or from first-generation immigrant families, many from India).<p>There is also a decided international emphasis today in terms of Valley companies using resources (people, investment sources, etc.) not at all centered in the Valley as they used to be.<p>The Valley connection does remain important in many key ways, however, as noted in the post - in my judgment, it is still by far the best place to be for a significant number of startups.<p>A good, balanced post on this issue.
