Asaf Rappaport Expands Investment Portfolio After $32B Wiz Cybersecurity Exit
Following the historic $32 billion sale of his cybersecurity company Wiz to Google Cloud, founder and CEO Asaf Rappaport has significantly broadened his private investment activities. According to Calcalist, Rappaport is now invested in dozens of startups, primarily in cybersecurity and artificial intelligence, as well as several leading global venture capital funds. Recently, he has also made moves in the communications sector through the philanthropic fund Merit Spread. Notably, Rappaport is in early talks to acquire a 25% stake in Herzliya Medical Center.
Rappaport’s investment style typically involves relatively small stakes, often several hundred thousand dollars, without active management involvement. Most opportunities come through founders or venture funds seeking his participation in funding rounds. His portfolio is heavily concentrated in cybersecurity and AI companies, including investments in Cyberstarts, Sequoia Capital, Andreessen Horowitz, and Index Ventures. Key startups in his portfolio include Anthropic, Deel, Torq, and Irregular, the latter ranked first among Calcalist’s 50 most promising startups for 2025.
He has also increased investments in early-stage funds, such as a recent pre-seed fund led by Merav Behat, a former colleague from Microsoft and co-founder of Dazz, which was acquired by Wiz. Rappaport and his three Wiz co-founders manage their exit proceeds through a family office led by Yotam Kostika, brother of co-founder Yinon Kostika.
Several of Rappaport’s investments have already yielded significant exits, including Cursor AI, acquired by SpaceX at a $60 billion valuation, and Armis, bought by ServiceNow for $7.75 billion. His extensive network in the cybersecurity industry stems from his founding of Adallom in 2012, which Microsoft acquired in 2015, and later from leading Microsoft’s security R&D center in Israel before founding Wiz in 2020.
In the communications sector, Rappaport and his partners invested via Merit Spread, which in March 2026 agreed to purchase 74% of Channel 13 from Access Industries for about $25 million, with a commitment to invest an additional $100-120 million over three years. In July, Merit Spread acquired 60% of Israel Entertainment’s parent company for 80 million shekels, with an option for an additional 25%. Following these deals, Idan Elrom was appointed acting CEO of Channel 13. The fund’s structure ensures donors do not directly hold media shares, preserving editorial independence.
