AI Security Startup AIR Raises $50M to Vet AI Agent Tooling

AI security startup AIR has emerged from stealth after raising $50 million across two seed rounds. The first round of $10 million was led by Sequoia, followed by a $40 million round led by Greenoaks, with participation from various angel investors including co-founders of Wiz and Clay. Founded by Unit 8200 veterans Yair Saban and Niv Hoffman, AIR addresses the security risks associated with the software supply chain for AI agents. The platform discovers agents operating within a company and continuously vets the skills, plug-ins, and MCP servers they use. AIR can block agents from interacting with external sources that fail security criteria and provides a marketplace for pre-vetted add-ons. CEO Yair Saban compares the current lack of oversight for AI agent tools to the unsigned drivers of the early 2000s, emphasizing the need for a signature-like verification system.
