Glow emerges from stealth as $1.2B unicorn, betting AI will redefine endpoint security

Glow, a cybersecurity startup founded by former Meta and Snowflake executives, emerged from stealth on Wednesday as a unicorn — betting that artificial intelligence is fundamentally reshaping how enterprises secure employee devices. The Palo Alto-based company raised $180 million in an all-equity Series A round at a $1.2 billion valuation, backed by Sequoia Capital, Cyberstarts, Greenoaks, Redpoint Ventures, Index Ventures, Swish Ventures, Lux Capital, Operator Collective, and Holly Ventures.

Why AI is forcing a rethink of endpoint security

As enterprises rapidly adopt AI tools and attackers increasingly use generative AI to automate phishing, develop malware, and launch more sophisticated attacks, companies are rethinking how they secure endpoints — from employee laptops to servers and connected devices. Concerns have intensified since Anthropic’s Mythos AI model demonstrated advanced capabilities in identifying and exploiting software vulnerabilities, sparking broader debate over AI-assisted cyberattacks.

Glow is betting that this shift requires a fundamentally new approach. The startup’s platform uses specialized AI agents to continuously map enterprise environments, assess risk in real time, and enforce security policies — aiming to prevent risky software, AI agents, and developer tools from entering enterprise environments in the first place.

Founded by industry veterans with deep enterprise experience

Glow was founded in 2025 by Roi Tiger (CEO), a former Meta vice president of engineering; Omer Singer, former head of cybersecurity strategy at Snowflake; Ophir Arie, former vice president of R&D at Claroty; and Arnon Joseph, a former Meta engineering leader. The leadership team also includes chief operating officer Emily Heath, a former CISO at United Airlines and DocuSign who served on the board of Wiz through its $32 billion acquisition by Google.

Despite only emerging from stealth, Glow said it already has paying customers across healthcare, retail, and financial services — though it declined to disclose names or numbers. Tiger told Bitcoin World that typical deployments span tens of thousands of employee devices across global organizations.

How Glow’s platform works

The platform uses AI models from Anthropic and Google’s Gemini, accessed through Amazon Bedrock, while Glow builds its own software to provide those models with enterprise context and improve reliability for security tasks. Tiger said the platform has already prevented malicious npm packages from being installed, 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.

The startup employs nearly 100 people, about 70% in Israel and the remainder in the U.S.

Competing in a crowded market

Glow enters an endpoint security market dominated by CrowdStrike, Microsoft, SentinelOne, and Palo Alto Networks. Tiger argues that existing endpoint detection and response products focus primarily on detecting threats after they emerge, whereas Glow is designed to prevent risky software from entering enterprise environments at all. Whether AI-native endpoint security platforms become a distinct category remains to be seen, as enterprises are only beginning to grapple with the security implications of increasingly capable AI models.

Conclusion

Glow’s emergence as a unicorn before publicly disclosing revenue metrics reflects strong investor conviction that AI will fundamentally change endpoint security. The startup’s focus on prevention rather than detection, combined with deep enterprise expertise in its founding team, positions it to challenge incumbents — but the market will ultimately decide whether its approach becomes a new standard or a niche solution.
