The founders
Glow’s leadership team reads like a checklist of security-industry veterans. CEO Roi Tiger spent nine years at Meta, most recently as VP of Engineering. CTO Omer Singer was previously Head of Cybersecurity Strategy at Snowflake. VP of R&D Ophir Arie came from the same role at Claroty, and Chief Product Officer Arnon Joseph spent eight years at Meta as Senior Director of Product. Rounding out the leadership bench, COO Emily Heath was CISO at United Airlines and DocuSign, and served on Wiz’s board through its $32 billion acquisition by Google.
What Glow does
Founded in 2025 and based in Palo Alto, Glow is built around a specific bet: that AI landing on the employee endpoint — agents, developer tools, and AI-assisted workflows installed faster than security teams can review them — requires prevention, not just detection. Traditional endpoint security tools flag risky behavior after it’s already happened; Glow instead runs specialized AI agents that continuously map what’s running across an organization’s devices, assess risk in real time, and proactively decide which software and AI agents are allowed to run before they act. The platform itself is powered by Anthropic and Google Gemini models served through Amazon Bedrock, layered with Glow’s own context engine tuned specifically for security decisions.
Even before this announcement, Glow said it already had paying customers across healthcare, retail, and financial services, with typical deployments spanning tens of thousands of employee devices at global organizations — the platform has reportedly already blocked malicious npm packages from being installed and flagged AI agents attempting to pull in risky third-party software.
The round
Glow emerged from stealth on July 22, 2026 with $180 million in an all-equity Series A funding round that valued the company at $1.2 billion, led by Sequoia Capital, Cyberstarts, Greenoaks, and Redpoint Ventures, with additional participation from Index Ventures, Swish Ventures, Lux Capital, Operator Collective, and Holly Ventures. The company plans to use the funding to expand its US go-to-market team and grow Glow Labs, its cybersecurity research division. It employs close to 100 people, about 70% of them in Israel.
Why it matters for founders
Glow enters a crowded endpoint security market already dominated by CrowdStrike, Microsoft, SentinelOne, and Palo Alto Networks — but its unicorn valuation at the moment of going public with its funding, rather than after years of building a revenue track record, signals how much investor appetite there currently is for security tooling purpose-built around AI-agent risk specifically, rather than general endpoint protection with AI features bolted on. For founders and engineering leaders evaluating how to let employees safely adopt coding agents and other AI tools at work, Glow is a concrete signal that “prevent risky AI agents before they run” is quickly becoming its own product category, not just a feature checkbox inside existing security suites.
