Greylock was founded in 1965 by Bill Elfers and Dan Gregory, joined shortly thereafter by Charlie Waite. Bill and Charlie had both worked at American Research and Development—one of the country’s first venture capital firms—while Dan was an investment manager at John P. Chase. The original capital ($9 million in total) was committed by a group of six prominent families, all of whom are still investors in Greylock.
Over the ensuing 43 years, Greylock has raised a series of partnerships, with current committed capital in excess of $2 billion, and helped build over 300 growth companies. Greylock's early-stage investments in recent years have included Corio, Xros (now part of Nortel), Sirocco Systems (now part of Sycamore Networks), Octane (now part of E.piphany), Red Hat, Phone.com (now Openwave Systems), ISS Group, DoubleClick, Open Market, Kiva Software (now part of Netscape), CheckFree, Cygnus (now part of Red Hat), Forte Software (now part of Sun Microsystems), Legato (now part of EMC), Trilogy, Clarus, Xircom (now part of Intel), Ascend Communications (now part of Lucent), and Copper Mountain Networks. Greylock has sponsored more companies to successful initial public offerings than any other early-stage venture firm, with over 125 total and has been lead or co-lead investor in most of these companies.
