Venture capital firm · Menlo Park · Founded 1972

Quick read

Kleiner Perkins, a multi-stage VC firm, founded in 1972 and headquartered in Menlo Park, California, is one of Silicon Valley's most storied venture firms with early bets on Google, Amazon, and Genentech. In March 2026, it raised $3.5B across two new funds—KP22, a $1B early-stage vehicle, and $2.5B in growth funds—with AI as the dominant theme across software, healthcare, transportation, and autonomy. After a publicly acknowledged difficult stretch, the firm deliberately rebuilt around a smaller, conviction-driven partnership led by Mamoon Hamid and Ilya Fushman.

Investment thesis

The firm takes a conviction-based approach—one sponsoring partner champions each deal before the full partnership—and positions itself as a hands-on builder alongside founders rather than a passive capital provider.
