Glilot Capital, founded in 2011, is one of Israel’s largest venture capital firms. The firm has built a reputation as a leading investor in cybersecurity and enterprise software startups, backing founders from seed through growth stages. With more than $1 billion under management, Glilot has become a cornerstone of Israel’s defense and cyber innovation ecosystem.
Glilot primarily invests in AI and cybersecurity startups, particularly those with dual-use applications and global scaling potential. The firm has a track record of supporting entrepreneurs building advanced solutions to protect enterprises and governments, while also expanding into complementary areas of enterprise technology.
In September 2025, Glilot Capital announced the close of $500 million across two new funds. The raise consisted of Glilot Seed Fund V and Glilot Plus, both designed to back early-stage Israeli startups in AI and cybersecurity. Each fund will target approximately 12 companies over the coming years, with half of the capital earmarked for new investments and the remainder allocated to follow-on rounds. The funds attracted capital largely from international investors, including U.S. and European pension funds and financial institutions, reflecting strong global confidence in Israel’s innovation ecosystem despite geopolitical challenges. This latest raise brings Glilot’s total assets under management to more than $1 billion, reinforcing its role as a dominant player in Israel’s tech sector.
