Kleiner Perkins is one of the oldest and most influential venture capital firms in the world, founded in 1972 in Menlo Park, California. For over five decades, the firm has backed companies including Google, Amazon, and Genentech, and continues to partner with founders from the earliest stages through to growth.
Kleiner Perkins invests across the AI landscape at early stage, with particular interest in professional services, healthcare, autonomy and robotics, cybersecurity, financial services, productivity tools, and the physical economy.
At growth stage, the firm selectively partners with breakout companies that have demonstrated clear AI leverage and are scaling with speed. The firm's view is that companies with genuine AI leverage can reach product-market fit and breakout growth faster than in any prior technology cycle.
In March 2026, Kleiner Perkins announced two new funds: KP22, a $1 billion early-stage fund and the firm's twenty-second venture fund, and approximately $2.5 billion in growth funds under KP Select IV. The combined $3.5 billion raise reflects the firm's conviction that the current AI cycle is one of the most important company-building moments in a generation.
KP22 targets early-stage companies being built from the ground up with AI at the core, across professional services, healthcare, autonomy, security, financial services, productivity, and the physical economy. KP Select IV focuses on breakout companies where the partnership's conviction continues to deepen.
Leadership
Kleiner Perkins operates as a partnership with multiple General Partners. Mamoon Hamid and Ilya Fushman lead the firm's enterprise and AI investing.

Investment Strategy
Kleiner Perkins invests broadly at early stage with KP22, and selectively at growth with KP Select IV, doubling down on breakout companies where conviction has deepened. The firm emphasizes lean investment and portfolio operating teams that engage on founder time. Its approach is described as bespoke and hands-on through all stages of growth.
