Assaf Rappaport’s 2026 deal spree: Inside the Wiz founder’s expanding AI investment map
His 10 investments in the first six months of the year span memory layers, identity security and autonomous defense systems.
Assaf Rappaport, the Wiz co-founder whose $32 billion sale of the cybersecurity unicorn to Google marked the largest exit in Israeli tech history, is emerging in 2026 as one of the most active angel investors in the global AI and cybersecurity ecosystem.
While Rappaport has long been associated with building companies rather than backing them, his investments show a deliberate shift: from operator to architect of a broader infrastructure layer spanning AI systems, enterprise security, and data-heavy applications.
Based on available disclosures, Rappaport has participated in at least 10 investments in 2026 to date, spanning early-stage Seed rounds through Series A financings. The full scope of his portfolio is likely broader, as many angel investments in the private market are not publicly reported.
The clearest pattern in Rappaport’s 2026 activity is a focus on what industry insiders increasingly describe as the “agentic and infrastructure layer” of AI, systems that are not only designed to process information, but to act autonomously within enterprise environments.
Among the most notable deals is Engram, a San Francisco-based startup developing what it calls an AI “memory layer” for enterprises. The company raised $98 million earlier this week, backed by Sequoia Capital and Kleiner Perkins, with Rappaport among its investors. Engram is attempting to address a long-standing constraint in generative AI systems: their inability to retain and structure organizational memory efficiently, leading to repeated processing costs and inefficiencies.
Also in June, Rappaport backed NewCore, which raised $66 million in Seed and pre-Seed funding. The company is focused on identity security, an area that has gained urgency as AI agents increasingly gain access to sensitive enterprise systems.
Another June investment, A Security, raised $37 million in combined Seed and follow-on financing, positioning itself in autonomous cyber defense. Unlike traditional cybersecurity tools that rely on static rules, A Security develops AI-driven systems designed to proactively simulate and counter machine-speed attacks.
In parallel, Ocean Security, which raised $28 million across Seed and Series A rounds, is building tools for agentic email defense, targeting a growing wave of AI-generated social engineering attacks that can mimic human communication at scale.
Rappaport’s portfolio also extends beyond cybersecurity into broader enterprise risk and applied AI systems.
Frame Security, which raised $50 million in May 2026, focuses on human-risk detection within organizations, an area that blends behavioral analytics with cybersecurity monitoring.
In March, Rappaport invested in JetStream, a California-based Seed-stage startup that raised $34 million for AI-driven cyber defense infrastructure.
Earlier in the year, in February 2026, he backed Fundamental, one of the largest and most unusual rounds in his portfolio. The company raised $255 million in total funding, including a $30 million Seed round and a $225 million Series A.
Also in February, he participated in a $25 million Series A funding round for Venice, an enterprise applications company formerly known as Valkyrie. The round was led by IVP and included Index Ventures and other prominent investors alongside Rappaport.
Rappaport’s known 2026 activity begins in January with two additional deals. Spirit, a cybersecurity company still operating in stealth, raised $50 million, while Genie Security, a smaller early-stage company that raised $3 million, was later acquired by Cyera.
Rappaport has several additional exits to his name as an investor. In late 2023, Palo Alto Networks paid $625 million for Talon Cyber Security, which developed an enterprise browser to secure distributed workforces. Weeks later, Check Point acquired Atmosec, a SaaS security startup Rappaport had backed at the Seed stage. The third exit came in June 2024, when exposure management company Tenable bought Eureka Security, a cloud data security posture management startup that Rappaport had backed alongside venture firm YL Ventures.
Rappaport also recently joined Merav Bahat, the founder of Dazz, whose company was acquired by Wiz for $450 million, in establishing a new founder-led fund expected to manage $25-30 million. The fund will focus on early-stage investments in AI infrastructure and AI-driven cybersecurity, with backing from Sequoia, Greylock, and Andreessen Horowitz.
