He 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.

The Business Story
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, 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.
His second chapter — quieter, larger in capital deployed, and substantially more under-covered in English — is aMoon Fund. 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.
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, whose Empire Online to Livermore arc is similarly invisible in English coverage.
Why He Matters in Israel
Two things, in sequence. First — as a Check Point co-founder, 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, 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. aMoon writes the checks.
What aMoon Does Today
aMoon Fund is Israel's largest dedicated healthtech and life sciences venture firm. Invests across early-stage and growth-stage health technology, biotech, AI-driven drug discovery, medical devices, and digital health. Multiple fund vintages. Capital deployed across U.S. and Israeli portfolio companies.
Key Holdings
- Check Point Software Technologies (CHKP) — founder stake
- aMoon Fund — founder and principal
- Multiple direct investments in Israeli healthtech and biotech
- Philanthropy through Nacht family vehicles
Legacy
Nacht is the rare Israeli founder who built a category-defining company, declined the public-figure path, and then deployed the resulting capital into the next category. From Check Point's stateful inspection firewall to aMoon's healthtech thesis — same investor discipline, two different decades.
Why He Matters Now
As AI-driven drug discovery and Israeli healthtech converge in 2026, aMoon is positioned to be the principal Israeli backer of the founders building in that intersection. Nacht's checks land in the rounds that matter. His next decade of capital allocation will shape what Israeli healthtech becomes.
