Located on the Pacific coast, San Francisco anchors the Bay Area innovation system. The city functions as a gateway between technology, finance, and global markets.

Founded during Spanish colonial expansion, San Francisco rose rapidly during the Gold Rush. In the late 20th and early 21st centuries it became the core urban node of Silicon Valley’s global technology ecosystem.
