Who Is Assaf Rappaport? The Wiz Co-Founder Behind Israel's Largest Exit Ever

The Builders  |  Israeli Cyber

Updated July 3, 2026

Assaf Rappaport co-founded Wiz in March 2020 with Ami Luttwak, Yinon Costica, and Roy Reznik — sold to Google in March 2026 for $32B, the largest Israeli tech exit in history and the largest acquisition in Google's history. He now runs Google Cloud Security. He rejected a $23B Google offer first, in July 2024.

Rappaport is the operating figure of a generation. Adallom to Microsoft. Microsoft Cloud Security Group. Wiz from zero to a $32B exit in under six years — the fastest company in software history to $100M ARR. Four co-founders who met on the bus to IDF service in 2001 walked away with multi-billion-dollar outcomes each.

The Business Story

Rappaport was born in Israel in 1982. He served in IDF Unit 8200 through the Talpiot program — the elite three-year track that combines academic degrees with intelligence-corps R&D. He met his eventual Wiz co-founders — Ami Luttwak, Yinon Costica, and Roy Reznik — on the bus to basic training in 2001. They stayed together through the army, university, and every company since.

Rappaport co-founded Adallom in 2012 with Luttwak and Costica. Adallom built cloud-access security for SaaS — one of the first pure-play CASB platforms. Microsoft acquired the company in July 2015 for $320 million. Rappaport moved to Microsoft to run the newly formed Cloud Security Group as Corporate Vice President — the executive who scaled Microsoft's cloud-native security portfolio for four years.

In March 2020 Rappaport left Microsoft with Luttwak, Costica, and Reznik to found Wiz. Tel Aviv-based. Agentless cloud-native application protection platform (CNAPP). The thesis: scan cloud infrastructure without agents, prioritize by attack path, deliver risk in a single graph. Wiz reached $100M ARR in 18 months — the fastest in SaaS history. Then $500M ARR by year four. Series E in 2024 at a $12B valuation. Sequoia, Index, Thrive, Andreessen Horowitz, Cyberstarts.

In July 2024, Google offered $23B to acquire Wiz. Rappaport turned it down. He wrote a public memo to Wiz employees: the company was going to build the world's leading cloud-security platform and take Wiz to $1B ARR and IPO. Eight months later, Wiz hit $700M ARR.

In March 2025, Google returned with a $32B all-cash offer. Rappaport accepted. The deal closed on March 11, 2026 — the largest acquisition in Google's history, the largest cybersecurity acquisition ever, and the largest Israeli technology exit on record. Rappaport is now CVP of Google Cloud Security, running the combined platform inside Google Cloud.

Why Rappaport Matters in Israel

Every Israeli cyber founder now benchmarks against Wiz. Fastest to $100M ARR. $32B exit. Four co-founders who stayed together across three companies and two decades. The template — Unit 8200 to Adallom to Microsoft to Wiz to Google — is now the reference arc for the next cohort. The Wiz founders' next moves will shape Israeli cyber's second act more than any single institutional investor decision.

What Wiz Does Today

Wiz operates as the cloud security backbone of Google Cloud, retained as a distinct platform under Rappaport's leadership. Agentless CNAPP across AWS, Azure, and GCP. Approximately $700M+ ARR at close. Thousands of enterprise customers including 40% of the Fortune 100. Tel Aviv engineering center retained and expanded. Palo Alto headquarters.

Rappaport's Key Holdings

• Wiz proceeds under Google
• Prior Adallom exit proceeds
• Personal Israeli startup investments through the four-founder syndicate
• Reported active limited-partner positions in Israeli early-stage cyber funds
• Philanthropy through the Rappaport family and Wiz-founder joint initiatives

Rappaport's Legacy

The $32B Google–Wiz deal is the largest Israeli tech exit ever recorded. Rappaport built the company that broke every Israeli SaaS growth benchmark on the way there. Turned down $23B. Took $32B. Kept the four co-founders in place through the whole arc. Kept the engineering in Israel. The clean case study for how Israeli cyber compounds — from Talpiot to a global platform inside the largest cloud.

Why Rappaport Matters Now

The test for the next five years is whether Wiz's culture survives inside Google Cloud. Rappaport's CVP role runs the experiment. If Wiz retains velocity as a Google-owned platform, the template becomes the model for the next wave of Israeli cyber consolidation. If it slows, the exit becomes the ceiling. The 2026–2028 chapter is the test.
