- Glow emerged from stealth with a $180 million all-equity Series A valuing it at $1.2 billion, backed by Sequoia Capital, Cyberstarts, Greenoaks, and Redpoint Ventures.
- Founded in 2025 by former Meta and Snowflake executives, it builds an endpoint platform that monitors the software, AI agents, and developer tools running on employee devices.
- It positions against CrowdStrike, Microsoft, SentinelOne, and Palo Alto Networks by preventing risky software from entering environments rather than detecting threats after the fact.
- The company says it already has paying customers in healthcare, retail, and financial services, with deployments spanning tens of thousands of devices.
What Happened
Glow, a Palo Alto-headquartered cybersecurity startup founded by former Meta and Snowflake executives, emerged from stealth as a unicorn, announcing a $180 million all-equity Series A at a $1.2 billion valuation, according to a July 22, 2026 report from TechCrunch. Backers include Sequoia Capital, Cyberstarts, Greenoaks, and Redpoint Ventures, with participation from Index Ventures, Swish Ventures, Lux Capital, Operator Collective, and Holly Ventures.
Why It Matters
The bet is that AI changes what an endpoint is. “If you think of the past decade, everything was moving to the cloud and SaaS. Suddenly, AI lands on the endpoint in a way we’ve never seen,” co-founder and CEO Roi Tiger said. As enterprises deploy AI tools and attackers use generative AI to automate phishing and develop malware, the attack surface on employee laptops and servers shifts. Concerns intensified after Anthropic unveiled its Mythos model, which it said showed advanced capability at identifying and exploiting software vulnerabilities.
Technical Details
Founded in 2025, Glow’s platform uses specialized AI agents to continuously map enterprise environments, assess risk in real time, and enforce security policies across the software, AI agents, and developer tools running on employee devices. It runs on models from Anthropic and Google’s Gemini via Amazon Bedrock, with Glow building its own software layer to supply enterprise context and improve reliability for security tasks. Tiger says the platform has already blocked malicious npm packages from being installed in customer environments, identified AI agents attempting to pull in such software, and detected devices where endpoint detection and response tools were missing or running with reduced functionality.
Who’s Affected
The founding team is unusually senior: Tiger is a former Meta vice president of engineering, joined by former Snowflake cybersecurity strategy head Omer Singer, former Claroty VP of R&D Ophir Arie, and former Meta engineering leader Arnon Joseph. COO Emily Heath was CISO at United Airlines and Docusign and sat on Wiz’s board through its $32 billion acquisition by Google. The company employs nearly 100 people, about 70% in Israel. Incumbents CrowdStrike, Microsoft, SentinelOne, and Palo Alto Networks are the direct competition.
What’s Next
Glow declined to disclose customer names or numbers, and reached unicorn status before publicly disclosing revenue metrics — so the growth claims remain unverified externally. The open question TechCrunch raises is whether AI-native endpoint security becomes a distinct category at all, given enterprises are only beginning to grapple with the security implications of increasingly capable models.
