Economic Impact

Top Silicon Valley companies founded or co-founded by those with a current or former affiliation with Stanford University, as an alumnus/alumna or faculty/staff.

In 2010, the 53 largest Silicon Valley companies on our list were responsible for generating sales totaling $267.4 billion. This represents 49.2% of the $543.9 billion total sales reported by the 150 firms that make up the The Silicon Valley 150 (an annual list of the largest Silicon Valley firms).

Those same 53 Stanford-affiliated companies reported income totaling $34.2 billion, or 40.3% of the $84.7 billion total income for the entire list of Silicon Valley 150 companies.

Further, the Stanford-affiliated companies on The Silicon Valley 150 list had a total market capitalization of $649.2 billion, representing 41.9% of the $1.55 trillion total market capitalization of the combined Silicon Valley 150 firms.

It should be stressed that $649.2 billion represents only a fraction of total market capitalization of the entire Wellspring list.

The following table, with information derived from The Silicon Valley 150, provides further details.
