A ssaf Rappaport is an Israeli technology entrepreneur and the co-founder and CEO of Wiz, a cloud security company that has achieved unicorn status faster than almost any other software company in history. Rappaport has a distinguished background in both technology and leadership. Before founding Wiz, he served as the general manager of R&D for Microsoft in Israel, a role he took on after Microsoft acquired his first startup, Adallom, for a reported $320 million in 2015.

In 2020, Rappaport and the same founding team from Adallom (Yinon Costica, Ami Luttwak, and Roy Reznik) left Microsoft to start Wiz. They created a platform designed to give companies a complete picture of their security risks across their cloud environments, a pressing need in the age of cloud computing. The company's agentless approach and ease of use led to hyper-growth, with Wiz reaching a multi-billion dollar valuation in less than two years. As CEO, Rappaport has been the public face and strategic leader of this phenomenal success story.
