Glow raised $180 million in a Series A round at a $1.2 billion valuation, announced July 22, 2026 and led by Sequoia Capital and Cyberstarts. The round came as the company emerged from stealth, arriving as a unicorn on day one — a bet on a security problem that barely existed a few years ago: autonomous AI agents running on corporate endpoints.
Here's the full breakdown of the raise, who backed it, and why investors are moving so fast on this category.
What is Glow?
Glow is an AI-powered endpoint security platform built to secure enterprise endpoints against autonomous AI agents. Founded in 2025 by Roi Tiger (CEO, ex-Meta), Omer Singer (CTO, ex-Snowflake CISO) and Ophir Arie (VP R&D, ex-Claroty), the company uses AI to map enterprise environments, continuously analyze risk, and automatically enforce security policies with a prevention-first approach.
The founding team's backgrounds — a former Meta executive, an ex-Snowflake CISO, and an industrial security veteran from Claroty — point to a product built by people who have sat on both the offense and defense side of enterprise security. Glow's early deployments span healthcare, retail and financial services, three sectors where compliance requirements make unauthorized software execution a particularly high-stakes problem, and where security teams are already under pressure to figure out how to govern employee use of AI tools.
The raise: $180M Series A
The headline numbers:
- Amount: $180 million
- Round: Series A
- Valuation: $1.2 billion
- Announced: July 22, 2026
- Lead investors: Sequoia Capital, Cyberstarts
- Co-leads: Greenoaks, Redpoint Ventures, Index Ventures
This financing follows a $20 million seed round and a previously disclosed $60 million Series A at a $400 million valuation. Combined, Glow's total funding stands at roughly $260 million — less than a year after the company was founded, and with a valuation that has already tripled since its earlier Series A pricing.
Who invested in Glow?
The round was led by Sequoia Capital and Cyberstarts, with Greenoaks, Redpoint Ventures and Index Ventures co-leading. Additional participants included:
- Lux Capital
- Operator Collective
- Holly Ventures
What Glow will do with the money
Glow said the funding will go toward go-to-market acceleration in the United States and expansion of Glow Labs, its R&D arm. That's a fairly typical split for a company launching out of stealth with a priced product already in the hands of enterprise customers — spend to land more deals while continuing to build out the underlying technology.
Focusing go-to-market spend specifically on the US, rather than a broader international push, suggests Glow is prioritizing depth in its most important market first — building out reference customers in healthcare, retail and financial services before expanding geographically. The R&D arm's separate branding as "Glow Labs" also hints at a company trying to keep its research function distinct from its commercial product team as it scales headcount quickly.
Why it matters
Glow's launch round says a lot about where enterprise security spending is heading in 2026, as AI agents move from experimental pilots into systems that touch real corporate infrastructure:
- AI agents are creating a new attack surface. Traditional endpoint security was built to manage human users clicking on things. Glow is betting that autonomous AI agents acting on corporate devices need a fundamentally different security model, and investors are pricing that as an urgent, not speculative, need.
- Investors are moving faster than usual for an unproven category. A $1.2 billion valuation for a company barely a year old, with three funding events already behind it, reflects how much capital is chasing security-for-AI-agents as a category — a dynamic also visible in the biggest funding rounds of 2026.
- Security and defense-adjacent AI startups are commanding premium pricing. Glow's rapid unicorn status sits alongside other high-valuation security launches tracked in AI defense tech funding for 2026, suggesting investors see AI-native security as one of the more durable enterprise AI categories.
