A cybersecurity startup most people have never heard of just landed a billion-dollar valuation before shipping a single public product roadmap. Glow, founded in Israel in 2025 by Roi Tiger, emerged from stealth mode in July 2026 with $180 million in funding and a thesis that traditional endpoint security is woefully unprepared for the AI agent era.
The investor roster includes Sequoia Capital, Index Ventures, Cyberstarts, Greenoaks, and Redpoint. The company had first surfaced in February 2026, with initial coverage revealing it had secured over $100 million at a valuation of $1 billion or more while still largely in stealth mode.
What Glow actually does
Enterprises have rushed to adopt AI agents, coding copilots, and autonomous developer tools, but the security infrastructure designed to monitor and protect endpoints was built for a world where humans were the ones clicking things. Glow’s platform uses its own AI agents to handle three core functions: asset intelligence, software control, and what the company calls “safe AI adoption.” The pitch is autonomous remediation and policy-driven control, meaning the system doesn’t just flag problems — it fixes them without waiting for a human to approve a ticket.
