Sand Hill Road, often shortened to just "Sand Hill", is an arterial road in Menlo Park, California, 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 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.
