Greylock

Greylock is a Silicon Valley venture capital firm that partners with technology founders at the earliest stages of company building. It invests selectively, backing founders working towards category-defining companies, and supports them with its partners, network and resources. The firm operates from offices in San Francisco and Menlo Park.

Sector coverage spans artificial intelligence, infrastructure, cybersecurity, fintech, deep technology, consumer technology and applications. Portfolio companies include Airbnb, Coinbase, Dropbox, Figma, LinkedIn and Palo Alto Networks - a pattern that stretches across consumer marketplaces, enterprise software and security infrastructure.

Alongside its investing activity, Greylock runs Edge, a bespoke three-month company-building program for pre-idea, pre-seed and seed founders. The program covers idea development, customer validation, design-partner introductions and early team building, with direct access to Greylock investors and AI researchers in residence, plus hiring and customer-development support and infrastructure and AI credits. The firm's stated approach to working with founders is hands-on and comparatively concentrated: fewer investments, closer involvement.
