About Glow

Glow is a cybersecurity company that has developed an AI-powered, prevention-first platform to secure modern enterprise endpoints. Founded in 2025, the company operates from Israel and the United States and emerged from stealth in July 2026 with $180 million in total funding at a $1.2 billion valuation. The funding was raised across three rounds in approximately one year and will be used to expand its U.S. go-to-market operations and its research arm, Glow Labs. Key investors include Sequoia Capital, Cyberstarts, Greenoaks, and Redpoint Ventures. The company was founded by CEO Roi Tiger, who was previously a VP of Engineering at Meta and founder of Onavo (acquired by Meta); CTO Omer Singer, former Head of Cybersecurity Strategy at Snowflake; and VP of R&D Ophir Arie, former VP of R&D at Claroty. The executive team also includes seasoned professionals from Meta, United Airlines, and DocuSign. This leadership team was assembled to address the evolving security challenges posed by the rapid adoption of AI tools within enterprises. Glow's business model is centered on selling its security platform to enterprise customers, and it has already secured clients in the financial services, healthcare, and retail sectors. The platform addresses the shortcomings of traditional, reactive security tools that are ill-equipped to handle environments where employees and autonomous AI systems frequently introduce new applications and risks. Glow's solution provides security teams with control over all software running on corporate endpoints. It deploys specialized AI agents that continuously map the environment, analyze risks in real-time, and automatically enforce policies to decide which software is permitted and which should be removed. By creating an adaptive, context-aware prevention system, the platform aims to significantly reduce the endpoint attack surface without impeding business operations, enabling employees to securely adopt new AI technologies.
