Cybersecurity startup Glow emerged from stealth on July 22, 2026, announcing a $180 million all-equity Series A round that values the company at $1.2 billion — making it one of the latest cybersecurity firms to reach unicorn status before publicly disclosing revenue figures.
The Palo Alto-based company was founded in 2025 by former Meta vice president of engineering Roi Tiger, former Snowflake cybersecurity strategy head Omer Singer, former Claroty vice president of research and development Ophir Arie, and former Meta engineering leader Arnon Joseph. The round was led by Sequoia Capital, Cyberstarts, Greenoaks, and Redpoint Ventures, with additional participation from Index Ventures, Swish Ventures, Lux Capital, Operator Collective, and Holly Ventures.
Glow is building an endpoint security platform designed to monitor and control the software, AI agents, and developer tools running on employee devices across enterprise environments. The platform uses AI agents to continuously map enterprise environments, assess risk in real time, and enforce security policies. It draws on AI models from Anthropic and Google’s Gemini through Amazon Bedrock, while building its own software to provide enterprise context and improve reliability for security tasks.
The company positions itself against established endpoint security vendors including CrowdStrike, Microsoft, SentinelOne, and Palo Alto Networks. Tiger said existing endpoint detection and response products focus primarily on detecting threats after they emerge, whereas Glow is designed to prevent risky software, AI agents, and developer tools from entering enterprise environments in the first place.
The timing reflects growing enterprise concern over AI-assisted cyberattacks. Anthropic’s Mythos AI model, which the company said demonstrated advanced capabilities in identifying and exploiting software vulnerabilities, has intensified debate over the risks posed by increasingly capable AI systems.
Glow said it already has paying customers in healthcare, retail, and financial services, with typical deployments spanning tens of thousands of devices across global organizations, though it declined to disclose customer names or numbers. The company employs nearly 100 people, approximately 70% based in Israel and the remainder in the United States.
