Cybersecurity Startup Glow Raises $180 Million in 15 Months at $1.2 Billion Valuation

Glow, an AI-driven cybersecurity company focused on endpoint protection, announced the completion of its seed, Series A, and Series B funding rounds totaling $180 million. The latest Series B round raised $100 million, led by Sequoia Capital, Cyberstarts, Greenoaks, and Redpoint Ventures, valuing the company at $1.2 billion. Founded in 2025, Glow has rapidly advanced through three funding rounds within about a year, starting with a $20 million seed round led by Sequoia and Cyberstarts, followed by a $60 million Series A led by Index Ventures at a $400 million valuation.

Glow currently employs around 100 people, with about 65 based in Israel, and operates from both Israel and the United States. The company has secured contracts with dozens of enterprise clients, including Fortune 500 companies across healthcare, retail, and financial services sectors. Co-founder and CEO Roy Tigger emphasized Glow’s comprehensive approach to endpoint security, leveraging AI to proactively prevent cyberattacks before they occur, contrasting with existing solutions that address only isolated issues.

The founding team includes Roy Tigger, former Meta VP of Engineering; co-founder and CTO Omer Zinger, who led cybersecurity strategy at Snowflake; and co-founder and VP of R&D Ofir Aryeh, a veteran of Israeli elite cyber units. The executive team also features Arnon Yosef, former Meta Senior Director of Product, and Emily Heath, former CISO of United Airlines and DocuSign and a partner at Cyberstarts.

Glow’s technology addresses the evolving risks posed by AI adoption in enterprises, where endpoint devices have become primary entry points for autonomous agents and new software tools. According to Verizon’s 2026 Data Breach Investigations Report, 45% of employees regularly use AI tools on corporate devices, up from 15% the previous year. Existing security tools are inadequate for this new threat landscape, as attackers exploit advanced AI capabilities, increasing the speed and severity of cyber risks. Despite growing demand for AI adoption, cybersecurity budgets are not keeping pace, challenging security teams to balance innovation with threat mitigation.

Cyberstarts founder Gili Ranen praised Glow’s leadership and team for their talent and determination to build a lasting company. Roy Tigger expressed confidence in achieving significant sales growth soon and highlighted the maturing Israeli tech ecosystem as a key factor in Glow’s ambitions to become a top global endpoint security provider.
