AI-powered endpoint security startup Glow today announced it has emerged from stealth mode with $180 million in Series A funding at a $1.2 billion valuation.
The investment round was led by Sequoia, Cyberstarts, Greenoaks, and Redpoint Ventures, with additional support from Index Ventures, Swish Ventures, Lux Capital, and Holly Ventures.
Based in Tel Aviv, Glow was founded in 2025 by CEO Roi Tiger, former VP of engineering at 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 company also employs Arnon Joseph as Chief Product Officer, who previously served as senior director of product at Meta, and Emily Heath as chief strategy officer, who previously was CISO at United Airlines and DocuSign, a board of directors member at Wiz, and a partner at Cyberstarts.
Glow aims to reduce risk in modern environments, which are dominated by employees’ use of AI and exposed to attacks that leverage Mythos-class capabilities and exploit weaknesses at machine speed.
For that, it provides security teams with control over what runs on the endpoint through specialized AI agents that map the environment and analyze risks in real time, and automatically enforce policies.
Glow leverages context and a reasoning engine to proactively allow or remove software, adapting to the environment to reduce the endpoint attack surface and allow employees to securely adopt and use AI.
While operating in stealth mode, Glow has signed enterprise customers across industries such as financial services, healthcare, and retail.
The startup will use the new investment to accelerate its go-to-market efforts in the US and to expand its research arm Glow Labs.
“I sat in the CISO seat for a long time, and I can tell you the tools available to us were never built for what enterprises face today. Every enterprise wants to move faster with AI. The question isn’t whether they’ll adopt it—it’s whether security can keep up. That’s the challenge Glow is solving,” Heath said.
