Mayfield (company)

Venture capital firm

Mayfield, also known as Mayfield Fund, is a US based venture capital firm that focuses on early stage to growth stage investments in enterprise and consumer technology companies. Founded in 1969 and based in Menlo Park, California, it is one of Silicon Valley's oldest venture capital firms.

The firm was founded in 1969 by venture capitalist Thomas J. Davis, Jr. and Wally Davis (no relation). Thomas Davis Jr. had earlier founded venture capital firm Davis & Rock with fellow investor Arthur Rock, with funding from several founders of Fairchild Semiconductor. William F. Miller, a former vice president and provost at Stanford University, was an early investor. In 2009 and 2010, Mayfield fully funded marketing automation software company Marketo's series C and D rounds, and benefited when the company went public in 2013. In September, Mayfield invested in Zimride's Series A funding round, a predecessor to ride hailing service Lyft. Also in 2011, Navin Chaddha took over as managing partner of Mayfield. In late 2012, Mayfield benefited from its investment in SolarCity when the solar energy company went public. In 2013, the firm relocated to its current office on Silicon Valley's Sand Hill Road, in Menlo Park. In April 2016, the firm closed two new funds totaling up to $525 million: Mayfield XV, a fund focused on early stage companies, and Mayfield Select, designed for later stage investing. In 2022, Navin Chaddha was named to the Midas List as the number 5 venture capitalist of the year. The firm is headquartered on Sand Hill Road in Menlo Park, California.

Mayfield is a sponsor of the Mayfield Fellows Program at Stanford University. The program offers university students in depth training and experience in high tech entrepreneurship.
