Kleiner Perkins

Activity from announced rounds

Activity in this selectionMar 31, 2026 · AI · Mar 1, 2026

Kleiner Perkins invests in technology companies from inception through IPO and beyond, combining early company formation with capital for later expansion.

The firm’s company-building work includes executive recruiting, business development and management systems. Its early work with Google included recruiting senior engineering and product leaders and introducing OKRs, giving a concrete example of how its role can extend beyond financing.

Its current AI thesis covers both foundational models and applications across industries. Kleiner’s investment in Anthropic reflects the former; its backing of enterprise products such as Rippling shows its interest in systems that become central to a customer’s operations.
