Glow, a Palo Alto-based cybersecurity startup, emerged from stealth mode on Wednesday as a unicorn after raising $180 million in Series A funding at a $1.2 billion valuation. The all-equity round was led by Sequoia Capital, Cyberstarts, Greenoaks, and Redpoint Ventures, with participation from Index Ventures, Swish Ventures, Lux Capital, Operator Collective, and Holly Ventures. Founded in 2025 by former executives from Meta and Snowflake, the company joins a growing list of cybersecurity startups achieving unicorn status before publicly disclosing revenue metrics.
The startup addresses a security challenge created by the rapid deployment of AI tools across enterprise environments. As attackers increasingly use generative AI to automate phishing campaigns and develop malware, companies face new risks from AI agents and developer tools running on employee devices. This concern intensified after Anthropic unveiled its Mythos AI model, which demonstrated advanced capabilities in identifying and exploiting software vulnerabilities.
Glow's platform uses specialized AI agents to continuously map enterprise environments, assess risk in real time, and enforce security policies across employee laptops, servers, and connected devices. The system leverages AI models from Anthropic and Google's Gemini through Amazon Bedrock, combined with proprietary software that provides enterprise context and improves model reliability for security tasks. According to CEO Roi Tiger, a former Meta vice president of engineering, the platform has already prevented malicious npm packages from being installed, identified AI agents attempting to pull in risky software, and detected devices with missing or degraded endpoint detection and response tools.
The company's leadership team includes co-founders Omer Singer (former Snowflake cybersecurity strategy head), Ophir Arie (former Claroty vice president of research and development), and Arnon Joseph (former Meta engineering leader). Chief operating officer Emily Heath previously served as CISO at United Airlines and DocuSign, and was on the board of Wiz through its $32 billion acquisition by Google. Glow currently employs nearly 100 people, with approximately 70% based in Israel and the remainder in the United States.
Glow enters a competitive endpoint security market dominated by established players including CrowdStrike, Microsoft, SentinelOne, and Palo Alto Networks. The startup differentiates itself by focusing on prevention rather than detection, aiming to stop risky software and AI agents from entering enterprise environments before threats emerge. While Glow reports having paying customers across healthcare, retail, and financial services with typical deployments spanning tens of thousands of devices, it has not disclosed specific customer names, numbers, or revenue figures. Whether AI-native endpoint security platforms will become a distinct market category remains uncertain as enterprises continue evaluating the security implications of increasingly capable AI models.
