Kleiner Perkins

Kleiner Perkins is one of Silicon Valley's oldest and most storied venture capital firms, founded in 1972 by Eugene Kleiner and Tom Perkins and headquartered on Sand Hill Road in Menlo Park, California, with additional offices in San Francisco and Shanghai. Across more than five decades and 21 venture funds plus 6 growth funds, the firm has invested over $10 billion and backed more than 900 ventures, including foundational companies such as Amazon, Google, Genentech, Electronic Arts, Juniper Networks, Intuit, Spotify, Figma, Robinhood, DoorDash, Duolingo and Databricks. Kleiner Perkins partners with founders from inception through IPO and beyond across early and growth stages, with seed rounds averaging roughly $4-5M and Series A rounds around $17-18M. In 2026 the firm announced its twenty-second venture fund, KP22, a $1B early-stage fund, alongside $2.5B in new growth funds. Current investment focus centers on artificial intelligence and AI safety, enterprise software, developer tools and infrastructure, healthcare and biotech, fintech, hardtech and autonomous systems, and cybersecurity, with a thesis that the right idea, team and partners can create an entirely new industry.
