Greylock Partners is one of the oldest venture capital firms in North America, founded in 1965 and based in Menlo Park, California, with over $3.5 billion in committed capital under management[2][3]. The firm focuses on early-stage consumer and enterprise software companies, positioning itself as the first institutional investor for exceptional founders, with over 80% of its investments occurring at Pre-Seed, Seed, or Series A stages[3][6]. Its investment thesis centers on AI-first software, cybersecurity, cloud infrastructure, developer tools, SaaS, consumer networks, marketplaces, fintech, and crypto, primarily within North America[1][6]. Typical check sizes range from $300K–$800K at Pre-Seed to $3M–$10M at Series A, and Greylock strongly prefers to lead rounds and secure high ownership[1][6]. Notable portfolio companies include Facebook (seed investor), Airbnb (early investor), LinkedIn, Figma, Discord, Workday, Okta, and Roblox[6]. A distinctive point of view is its explicit branding as “Your First Partner” and its specialization in backing founders at the concept stage, often when ideas are still on whiteboards, with a hands-on, long-term partnership model[1][6].
