Sand Hill Road

Sand Hill Road, often shortened to just "Sand Hill", is an arterial road in western Silicon Valley, California, running through Palo Alto, Menlo Park, and Woodside, notable for its concentration of venture capital companies. The road has become a metonym for that industry; nearly every top Silicon Valley company has been the beneficiary of early funding from firms on Sand Hill Road.
Its significance as a symbol of private equity and venture capitalism in the United States is compared to that of Wall Street and the stock market, and K Street in Washington, D.C. and political lobbying, or Madison Avenue for the advertising industry.
