Glow, a cybersecurity startup built by former Meta and Snowflake engineers, slipped out of stealth today with a blockbuster $180 million Series A that values the company at $1.2 billion. Planting its U.S. headquarters in Palo Alto, the company says the cash will fuel a hiring sprint and turbocharge Glow Labs, its AI research arm, as it pushes a product meant to keep risky software and agentic AI tools from ever touching corporate endpoints. Glow plans to show off what it has built at Black Hat USA in Las Vegas next month.
Funding and backers
The round was co-led by Sequoia Capital, Cyberstarts, Greenoaks and Redpoint Ventures, with Index Ventures, Swish Ventures, Lux Capital, Operator Collective and Holly Ventures also joining in, according to a press release cited by StreetInsider. Glow says the $180 million haul instantly puts it in unicorn territory with a $1.2 billion valuation and will bankroll its U.S. go-to-market push and continued research.
Who’s behind Glow
Glow was founded in 2025 by CEO Roi Tiger, alongside co-founders Omer Singer and Ophir Arie, with Arnon Joseph as chief product officer and Emily Heath as chief operating officer, San Francisco Business Times reporting shows. The leadership bench pulls from Meta, Snowflake, Claroty and senior enterprise security roles, a résumé stack that backers say gives Glow instant credibility as it jumps into the crowded endpoint security ring.
Prevention-first pitch
Glow casts itself as a prevention-first endpoint security platform, running specialized AI agents directly on devices to map active software, gauge risk in real time and stop dangerous packages before they install, instead of leaning only on after-the-fact detection, according to SiliconANGLE. The company frames that approach as a direct response to the surge in AI-driven workflows and increasingly "agentic" tools that traditional endpoint stacks were never built to corral.
Why investors are paying up
Investors have been betting heavily on Israeli and agent-focused security startups after a run of splashy exits and accelerating enterprise AI adoption, and Glow’s founders and prevention-first strategy slot neatly into that storyline. Big-ticket deals such as Google’s $32 billion purchase of Wiz have reset expectations across the sector and helped normalize writing large checks to pre-product cyber companies, as TechCrunch reported. Glow has also said it has already landed enterprise customers in healthcare, retail and finance, according to the company release.
What’s next
Glow says it will put the new capital to work accelerating U.S. hiring and expanding Glow Labs, and it plans to highlight its technology at the Black Hat House of Glow in Las Vegas from August 3-5, according to the company release and local coverage by the San Francisco Business Times. For Bay Area security talent, the Palo Alto hub adds another well-funded contender to a neighborhood already dominated by CrowdStrike, SentinelOne and Palo Alto Networks.
