SOMA's hot, but study finds heart of tech success in Silicon Valley

By Cromwell Schubarth in Silicon Valley Business Journal

A hive of successful tech startups are buzzing around San Francisco's South of Market neighborhood, but a new study shows the highest concentration of successful new companies in the region is to the south, in Silicon Valley. This may be confusing to people from outside of the region and to boosters in San Francisco, some of whom have even argued that the city is overshadowing the Valley.

But a paper by economists at the Massachusetts Institute of Technology published on Friday in the journal Science shows the top locations for successful tech startups in the Bay Area are clustered in Santa Clara and San Mateo counties or near universities and national laboratories.
