The Two Miles That Priced Half the Internet

Sand Hill Road did not become Sand Hill Road by accident. When Kleiner Perkins and Sequoia Capital both established offices on the road in 1972, they were choosing proximity to Stanford University and to the semiconductor firms already clustering around Palo Alto — not proximity to money, which had always lived on Wall Street. The road itself is unremarkable: a two-lane stretch running roughly east–west through Menlo Park, flanked by low-rise office parks and mature oaks, with no signage announcing its significance.

Kleiner Perkins settled at 3000 Sand Hill Road, a campus-style complex of linked buildings that became the most famous address in venture capital. Sequoia took space nearby. Through the late 1970s and 1980s the road accumulated partnerships in the way a coastline accumulates driftwood — New Enterprise Associates, Institutional Venture Partners, Mayfield Fund — until it held a critical mass that made locating anywhere else feel eccentric. The 1979 Department of Labor clarification of the ERISA prudent man rule, which freed pension funds to allocate to venture capital, brought fresh capital to the road without requiring its managers to move a single desk.

The dot-com boom made Sand Hill Road briefly famous to people who had never heard of it. Firms that had operated in relative obscurity — raising funds of $50m to $150m, backing companies over years — found themselves processing term sheets for internet businesses that had existed for months. Sequoia's investment in Google in 1999, alongside Kleiner Perkins, at a combined $25m for roughly 20 percent of the company (figures recorded by the SEC in subsequent filings) became the canonical example of what the road could produce when it worked. When the Nasdaq composite peaked at 5,048.62 on 10 March 2000 and then collapsed, the road survived where the companies it had funded did not.

Andreessen Horowitz, founded in 2009 by Marc Andreessen and Ben Horowitz, established its offices on the road and immediately disrupted its culture — paying market salaries for operational staff, promising portfolio companies a full-service firm rather than a partnership of investors. By 2012 it had raised over $2.7bn across three funds, according to SEC Form D filings. The arrival of SoftBank's Vision Fund after 2017 — which wrote checks an order of magnitude larger than anything Sand Hill Road had normalised — pressured every firm on the road to move faster and at higher valuations than their own models had ever assumed.

Sand Hill Road never had a stock ticker, a regulator, or a single governing body. Its authority derived entirely from repetition: the firms here had backed Fairchild's successors, then Apple, then Netscape, then Google, then Facebook, and the pattern compounded into a geography of credibility that founders treated as a destination in its own right. Rents in the office parks along the road reflected this. The concentration also produced its failures — Theranos raised money from investors whose offices were a short drive from Palo Alto, and WeWork's Vision Fund–backed ascent and collapse was partly a story of capital that moved too fast to ask the questions the road's older partnerships had once required.

By the early 2020s, remote work and the rise of multi-city firms had loosened the road's grip. New York offices opened; deals were done over video. But the partnerships that shaped the industry's vocabulary, its standard term sheets, and its pricing assumptions for five decades were built in those low-rise buildings behind the oaks on a two-lane road in Menlo Park.
