Assaf Rappaport has always had a knack for turning startups into goldmines. But his latest move just rewrote the record books. The Israeli entrepreneur and former Microsoft executive is the driving force behind Wiz, a cloud security powerhouse that Google acquired for a jaw-dropping $32 billion—marking the tech giant’s largest acquisition to date.
Founded only five years ago, Wiz quickly climbed the ranks to become a major player in the cloud security industry. Backed by an impressive roster of clients, including Salesforce, BMW, and Slack, the company has seen explosive growth. Analysts now predict Wiz will generate over $1 billion in annual recurring revenue (ARR) by 2025—a remarkable feat for such a young startup.
Not Rappaport’s First Big Win in Cybersecurity
For Assaf Rappaport, this historic sale is yet another milestone in a career filled with big wins. Long before Wiz, he co-founded Adallom, a cybersecurity venture that caught Microsoft’s attention. In 2015, the tech giant acquired Adallom for $320 million, propelling Rappaport into a leadership role as the head of Microsoft’s cloud security division.
After three years at Microsoft, Rappaport set his sights higher. Driven by a vision to revolutionize cloud security, he left the corporate world behind and co-launched Wiz—a bold move that’s now paid off far beyond expectations.
From IPO Dreams to a $32 Billion Payday
Interestingly, this massive sale to Google wasn’t part of the original plan. In 2024, Rappaport and his team walked away from a $23 billion buyout offer from the search giant, holding out for an initial public offering (IPO) instead. However, when Google returned with an irresistible $32 billion all-cash deal, the Wiz team couldn’t say no.
With this blockbuster acquisition, Rappaport’s net worth skyrocketed. As of March 2025, he’s now among Israel’s richest tech founders, boasting an estimated fortune of $1.2 billion.
Google Scores Big With Wiz Acquisition
For Google, acquiring Wiz is a strategic move to solidify its position in the fiercely competitive cloud security market. As businesses increasingly shift to cloud-based solutions, cybersecurity has become more critical than ever. Wiz’s rapid growth, innovative technology, and blue-chip client base made it a prime target.
Now under Google’s umbrella, Wiz is set to expand even faster, giving Google a significant edge over rivals like Amazon Web Services and Microsoft Azure.
What’s Next for Rappaport?
While details of Rappaport’s next move remain under wraps, his track record suggests he won’t be slowing down anytime soon. Whether he stays on to steer Wiz’s next chapter under Google or ventures into new territory, one thing’s clear—Assaf Rappaport has cemented his status as one of Israel’s most successful tech entrepreneurs.
