Key Takeaways
- • Assaf Rappaport, Wiz co-founder whose $32 billion Google acquisition marked Israeli tech's largest exit, has deployed capital across at least 10 investments in the first half of 2026, signaling a strategic pivot from operator to venture investor in AI and cybersecurity infrastructure.
- • Rappaport's 2026 portfolio focuses on the "agentic and infrastructure layer" of AI systems—autonomous enterprise applications spanning memory layers, identity security, and autonomous defense systems that address fundamental constraints in generative AI deployment.
- • Engram, a San Francisco-based AI memory layer startup, raised $98 million in funding backed by Sequoia Capital and Kleiner Perkins, with Rappaport among investors; NewCore raised $66 million in Seed and pre-Seed funding, also backed by Rappaport, exemplifying the deal activity.
- • The investment pattern reflects a deliberate strategic thesis: building foundational infrastructure for enterprise AI that extends beyond cloud security into autonomous systems and organizational memory retention, areas where traditional AI systems face efficiency constraints.
- • Many of Rappaport's angel investments remain undisclosed, indicating the full scope of his 2026 portfolio activity is likely significantly broader than publicly reported deals.
Summary
Assaf Rappaport, the Israeli entrepreneur who built Wiz into a $10 billion cloud security unicorn before its landmark $32 billion acquisition by Google—the largest exit in Israeli tech history—has emerged in 2026 as one of the most active angel investors in the global AI and cybersecurity ecosystem. This represents a significant strategic shift for Rappaport, transitioning from his primary focus as a company builder and operator to what industry observers describe as an architect of broader infrastructure layers spanning AI systems, enterprise security, and data-intensive applications.
Rappaport's investment activity in the first half of 2026 encompasses at least 10 documented investments spanning early-stage Seed rounds through Series A financings. However, given the private nature of many angel investments, which often remain undisclosed, the full breadth of his portfolio is likely substantially larger. The investments reflect a cohesive strategic thesis centered on what industry insiders increasingly term the "agentic and infrastructure layer" of artificial intelligence—systems engineered not merely to process information but to act autonomously within enterprise environments.
Among the most prominent recent deals is Engram, a San Francisco-based startup developing an AI "memory layer" for enterprise applications. The company closed a $98 million funding round earlier in June 2026, with backing from venture capital firms Sequoia Capital and Kleiner Perkins, alongside Rappaport's participation. Engram addresses a critical constraint limiting generative AI's enterprise deployment: the inability to efficiently retain and structure organizational memory, a limitation that creates repeated processing costs and operational inefficiencies. Additionally, Rappaport backed NewCore, which secured $66 million in combined Seed and pre-Seed funding, further exemplifying his portfolio concentration in infrastructure-layer solutions.
The investment pattern reveals a deliberate architectural vision extending well beyond Rappaport's founding achievements in cloud security. His 2026 commitments span memory layers, identity security, and autonomous defense systems—collectively representing a foundational infrastructure approach to enterprise AI challenges. This positions Rappaport not as a passive capital provider, but as a strategic thought leader actively shaping the next generation of AI and cybersecurity infrastructure, leveraging both his technical expertise from his Microsoft and Wiz tenures and the credibility earned from one of technology's most successful recent exits.
