Glow, a cybersecurity startup founded by former Meta and Snowflake executives, has emerged from stealth with a $1.2 billion valuation. The Palo Alto-headquartered company is betting that artificial intelligence (AI) is reshaping how enterprises secure employee devices and is positioning itself to challenge the existing endpoint security market dominated by companies like CrowdStrike, Microsoft, SentinelOne, and Palo Alto Networks.
A New Approach to Endpoint Security
Glow’s platform uses specialized AI agents to continuously map enterprise environments, assess risk in real-time, and enforce security policies. This approach is a departure from traditional endpoint detection and response products that focus primarily on detecting threats after they emerge. Glow’s founders believe that this shift requires a new approach to endpoint security, one that prevents risky software, AI agents, and developer tools from entering enterprise environments in the first place.
Founding Team and Funding Round
Glow was founded in 2025 by Roi Tiger, a former Meta vice president of engineering, Omer Singer, a former Snowflake cybersecurity strategy head, Ophir Arie, a former Claroty vice president of research and development, and Arnon Joseph, a former Meta engineering leader. The company has raised $180 million in an all-equity Series A funding round that valued it at $1.2 billion. The investment was led by Sequoia Capital, Cyberstarts, Greenoaks, and Redpoint Ventures, with participation from Index Ventures, Swish Ventures, Lux Capital, Operator Collective, and Holly Ventures.
AI-Powered Endpoint Security Platform
Glow’s platform uses AI models from Anthropic and Google’s Gemini through Amazon Bedrock to power its security capabilities. However, the company is building its own software to provide these models with enterprise context and improve their reliability for security tasks. The platform has already prevented malicious npm packages, third-party software components used to build applications, from being installed in customer environments, identified AI agents attempting to pull in such software, and detected employee devices where endpoint detection and response tools were missing or operating with reduced functionality.
Market Competition and Future Outlook
Glow enters a crowded endpoint security market, but its founders believe that their approach is unique and addresses the evolving threat landscape. The company’s leadership team includes chief operating officer Emily Heath, a former chief information security officer at United Airlines and DocuSign who served on the board of Wiz through its $32 billion acquisition by Google. Glow has already gained paying customers across industries including healthcare, retail, and financial services, but declined to disclose customer names and numbers.
Conclusion
Glow’s emergence from stealth marks a significant development in the cybersecurity space, as companies like Anthropic unveil AI models that can identify and exploit software vulnerabilities. The $1.2 billion valuation is a testament to the company’s potential to revolutionize endpoint security in the AI era. As enterprises continue to grapple with the security implications of increasingly capable AI models, Glow’s innovative approach may prove to be a game-changer.
