Greylock

Greylock is one of Silicon Valley's oldest and most storied venture capital firms (founded 1965), focused on being the first institutional partner for exceptional founders. Over 80% of investments are first checks at Pre-Seed, Seed, or Series A. The firm has evolved to an explicitly AI-first positioning, backing founders building software that reshapes enterprise and consumer industries. Greylock operates a bespoke company-building program (Greylock Edge) for pre-idea and pre-seed founders, offering flexible financing and deep operational partnership from inception through product-market fit.
