Marius Nacht co-founded Check Point with Gil Shwed and Shlomo Kramer in 1993 — and then quietly built Israel's largest dedicated healthtech investment vehicle. Two career chapters, one Lanir test: Hebrew Wikipedia tracks him, English Wikipedia barely does.

Marius Nacht's Business Story: Check Point Co-Founder to aMoon Architect
Marius Nacht co-founded Check Point Software Technologies in 1993 with Gil Shwed and Shlomo Kramer. While Shwed became the public face and CEO and Kramer left to found new companies, Marius Nacht stayed at Check Point for years in technical and strategic roles, holding his founder's stake as the company built into a NASDAQ-listed multi-billion-dollar enterprise software business.
Marius Nacht's second chapter — quieter, larger in capital deployed, and substantially more under-covered in English — is aMoon Fund. Marius Nacht founded aMoon in 2016 as Israel's first dedicated healthtech and life sciences venture firm at institutional scale. The fund grew through multiple vintages to over $1 billion in committed capital, with investments across U.S. and Israeli healthtech, biotech, pharma, and medical devices.
aMoon's portfolio companies have included some of the most ambitious health-tech bets out of Israel — names spanning AI-driven drug discovery, novel therapeutics, and digital health infrastructure. The fund operates with an institutional patience rare in Israeli VC.
Marius Nacht is one of the most under-covered figures in Israeli technology in English. He gives almost no interviews. He doesn't speak at the celebrity-tech conferences. His name surfaces in fund filings, board listings, and Hebrew business press — not in feature profiles — much like fellow Builders figure Noam Lanir.
Why Marius Nacht Matters in Israeli Technology
Two things, in sequence. First — as a Check Point co-founder, Marius Nacht is part of the triumvirate that built the institutional reference point for Israeli cybersecurity. Second, and arguably more strategic for Israel today — through aMoon, Marius Nacht has become the principal patient-capital backer of Israeli healthtech at the moment AI-driven drug discovery is reshaping the global pharma industry. Israel produces the founders. Marius Nacht's aMoon writes the checks.
