Glow raises $180M Series A at $1.2B valuation for AI endpoint security solving shadow AI
Cybersecurity startup Glow announced a $180 million Series A led jointly by Sequoia Capital, Cyberstarts, Greenoaks, and Redpoint Ventures, with participation from Index Ventures, Swish Ventures, Lux Capital, Operator Collective, and Holly Ventures. Founded in 2025 and emerging from stealth, the company achieves unicorn status with a $1.2 billion valuation. Glow builds an endpoint security platform that automatically discovers all software running on employee devices — including unapproved AI tools — and enforces governance to prevent data leakage from so-called "shadow AI." The platform combines asset intelligence, software control, and safe AI adoption modules. CEO Roi Tiger was formerly VP Engineering at Meta; COO Emily Heath was CISO at United Airlines and DocuSign and sits on Wiz's board.
Why it matters: Glow's rapid ascent signals that the "shadow AI" problem — employees adopting unauthorized AI agents and tools on corporate devices — has become a board-level enterprise risk, creating a new endpoint security sub-segment. The company is targeting the detection and governance gap left by traditional cybersecurity products that were designed for known threats rather than the explosion of unapproved AI tooling. Glow's ability to raise a mega-round from top-tier cross-border investors (Sequoia, Cyberstarts, Greenoaks, Redpoint) less than 18 months after founding, without a prior public funding history, exemplifies the "fastest-ARR-ramp" pattern driven by enterprise demand for AI governance. The round size and velocity also reflect capital-cycle dynamics where cybersecurity AI-native startups are commanding premiums.
Grounded expert take: Glow is not just a cybersecurity story — it is a signal that the enterprise AI adoption governance gap is now large enough to support a standalone category. With Meta, Snowflake, and Wiz alumni on the leadership team, the company has deep credibility in both AI engineering and enterprise security procurement. The shadow AI problem is structurally more acute than previous shadow IT waves because AI agents can exfiltrate data autonomously, making manual oversight impossible. Glow's platform addresses a market failure in existing endpoint detection and response (EDR) systems that lack visibility into AI tool behavior. Expect incumbent vendors like CrowdStrike and SentinelOne to respond with AI governance features, likely through acquisition or rapid product builds. Glow's $180M Series A at a $1.2B valuation also validates that enterprise security infrastructure companies can still achieve hypergrowth unicorn outcomes in a cautious funding environment.
