The round was led by Sequoia Capital, Cyberstarts, Greenoaks and Redpoint Ventures, with participation from Index Ventures, Swish Ventures, Lux Capital, Operator Collective and Holly Ventures. Glow operates from Tel Aviv and Palo Alto. CEO Roi Tiger spent nine years at Meta, most recently as VP of Engineering, and previously co-founded Onavo, which Facebook acquired in 2013. CTO Omer Singer led cybersecurity strategy at Snowflake, and VP R&D Ophir Arie held the same role at Claroty.
Enterprise customers signed before launch
Glow states it has signed enterprise customers in healthcare, retail and financial services during its stealth phase, though it has not named them or disclosed revenue, so these remain company claims for now. The company has also recruited heavyweight operators: COO Emily Heath was CISO at United Airlines and DocuSign and sits on the board of Wiz, and Chief Product Officer Arnon Joseph spent eight years at Meta as a senior product director.
Endpoint security becomes an AI battleground
The bet behind the round is that AI agents operating on employee devices break the assumptions of detection-based endpoint tools from vendors such as CrowdStrike and SentinelOne. Glow’s product uses specialized AI agents to map the environment, analyze risk in real time and enforce policies automatically, controlling what is allowed to run rather than detecting attacks after the fact. Tiger argues prevention was always the right answer in security and that AI finally makes it operationally viable. The 1.2 billion dollar day-one valuation reflects investor conviction that a new endpoint category is opening.
Analysis: a born unicorn raises the bar, and the burn
For security founders the opportunity is real: agentic AI creates genuinely new attack surface, and buyers are actively budgeting for it. CISOs currently have no standard answer to the question of what an autonomous agent may execute on a corporate laptop. Startups that define controls for agent behavior, allowlisting, and machine identity can ride the same procurement wave Glow is targeting, including as smaller specialists that integrate with existing platforms rather than replacing them.
The risk is the funding structure itself. A 180 million dollar Series A at 1.2 billion dollars, before public reference customers or disclosed revenue, prices in flawless execution against incumbents with massive install bases. The replicable lesson is Glow’s team construction: repeat founders paired credible security operators with named enterprise logos in exec roles, which is what makes a valuation like this even discussable. Founders without that pedigree should expect very different terms for the same market thesis.
