A cybersecurity startup founded last year by former Meta and Snowflake executives just raised $180 million at a $1.2 billion valuation before disclosing a dollar of revenue. Glow emerged from stealth on Wednesday with a Series A led by Sequoia Capital, Cyberstarts, Greenoaks and Redpoint Ventures, joined by Index Ventures, Swish Ventures, Lux Capital, Operator Collective and Holly Ventures. The round makes Glow the latest security company to reach unicorn status on the strength of a narrative rather than financials, a feat that has become almost routine in the AI era.

The narrative is that artificial intelligence has fundamentally broken the endpoint security model. Anthropic's Mythos model demonstrated an ability to identify and exploit software vulnerabilities at a level that unsettled researchers, while enterprises race to deploy AI tools that attackers are already using to automate phishing and malware development. Glow's bet is that the endpoint, spanning laptops, servers and developer machines, has become the new frontier because AI agents now run locally in ways the cloud-centric security stack was never built to see.

The company's platform uses specialized AI agents, powered by Anthropic and Google's Gemini models accessed through Amazon Bedrock, to continuously map what software, AI tools and developer components are running on employee devices and block risky ones before they execute. Roi Tiger, Glow's chief executive and a former Meta vice president of engineering, argues that incumbents like CrowdStrike, Microsoft, SentinelOne and Palo Alto Networks are architected for detection after the fact, while Glow prevents unauthorized software, including malicious npm packages and AI agents pulling in dependencies, from entering the environment in the first place.

Tiger co-founded Glow with Omer Singer, formerly Snowflake's cybersecurity strategy head; Ophir Arie, formerly Claroty's vice president of research and development; and Arnon Joseph, another Meta engineering veteran. The operating chief is Emily Heath, a former chief information security officer at United Airlines and DocuSign who sat on Wiz's board through its $32 billion sale to Google and previously partnered at Cyberstarts, one of Glow's backers. The team of nearly 100 splits roughly 70 percent in Israel and the rest in the United States.

What Glow does not have yet are disclosed customer names, customer counts or revenue figures. The company says it has paying deployments across healthcare, retail and financial services spanning tens of thousands of devices, but declined to be more specific. In a market where endpoint detection and response is a crowded, mature category dominated by public companies including CrowdStrike, Microsoft, SentinelOne and Palo Alto Networks, a unicorn that has not disclosed revenue metrics arguing for a prevention-first architecture is a thesis that still needs proving.

The next test is whether Glow's prevention claims hold at scale across heterogeneous enterprise environments, and whether the startup can convert early customers into a revenue trajectory that justifies the valuation. The investors have bet that the AI shift creates a generational opening. The market will decide if that opening belongs to a newcomer or the incumbents who are already bolting AI onto their own agents.
