AI security startup Glow emerges from stealth with $180 million at $1.2 billion valuation Founded by former Meta, Snowflake and Claroty executives, the company is betting AI can transform endpoint security from reactive defense to prevention. Cybersecurity startup Glow has emerged from stealth with $180 million in funding at a $1.2 billion valuation, aiming to build a new approach to endpoint security designed for an era in which employees and autonomous AI systems increasingly operate inside enterprise networks. The company, founded in 2025 by former executives from Meta, Snowflake and Claroty, said its latest financing round was led by Sequoia Capital, Cyberstarts, Greenoaks and Redpoint Ventures, with participation from Index Ventures, Swish Ventures, Lux Capital and Holly Ventures. Glow has raised $180 million across three rounds in roughly one year, including a $20 million Seed round led by Sequoia and Cyberstarts, a $60 million Series A led by Index Ventures with participation from Greenoaks at a $400 million valuation, and the current $100 million Series B. The company plans to use the funding to expand its go-to-market operations in the United States and grow Glow Labs, its research arm. Glow currently employs approximately 100 people, including around 65 in Israel, and operates from Israel and the United States. The company said it has signed enterprise customers across industries including healthcare, retail and financial services. Glow is targeting the endpoint security market, where companies have traditionally relied on multiple specialized products to protect employee devices, applications and corporate data.

Each company solves something small there and does not offer a comprehensive solution,” Tiger told Calcalist. “We offer a broad solution
