AIR Raises $50M Across Two Seed Rounds to Secure AI Agents’ Tool Supply Chain
The stealth exit bundles $10 million led by Sequoia and $40 million led by Greenoaks for a security platform that discovers agent add-ons and rechecks them as they change.
A security layer for agent tools
AIR’s platform gives security teams visibility into the AI agents operating inside company systems and the skills, plug-ins, MCP servers and other components those agents use. It can assess those additions against security criteria and block agents from reaching tools or external sources that fail policy checks.
Approval has to keep up with change
A tool that passed review can become risky when its package or maintainer changes. AIR says it continuously evaluates publicly available agent add-ons and monitors them for malicious changes, then uses an enforcement layer to inspect activity such as loading a skill or retrieving web content. The company told TechCrunch that its service was filtering about 27% of the add-ons and skills it found online.
An early enterprise market
AIR is emerging from stealth with more than 20 customers, including large enterprises, according to CEO Yair Saban. The company has seen particular demand in financial services and pharmaceuticals, where agents can touch sensitive systems and data. The two seed rounds give AIR resources to grow its research team and expand go-to-market work in the United States and Europe.
