Glow exits stealth with $180M Series A at $1.2B for AI security agents

Glow, a cybersecurity startup founded by ex-Meta and Snowflake executives, emerged from stealth with a $180 million Series A at a $1.2 billion valuation. The company uses AI agents to continuously monitor software and developer tools for security oversight.
Key takeaway
Investor appetite is concentrating on agentic monitoring inside the developer toolchain, not only on traditional static scanners or perimeter products.
Context
Glow positions AI agents as continuous overseers of software and developer tooling rather than one-off scanners, aiming to automate security review as code and tooling change. Founding leadership from Meta and Snowflake is being used as a credibility signal that the product is built for large-scale engineering environments.
The $180 million Series A and $1.2 billion valuation put Glow in the same class of high-conviction AI security financings that markets have recently rewarded. For operators, the practical implication is faster vendor consolidation pressure around agent-driven AppSec and developer-tool monitoring.
