AI security startup AIR has officially launched from stealth mode, announcing a significant $50 million funding raise aimed at securing the complex supply chain of AI agents. The company's mission is to provide oversight for the burgeoning ecosystem of plug-ins, skills, and Model Context Protocol (MCP) servers that enable AI agents to interact with corporate systems and the internet. This funding marks a major step in addressing a critical vulnerability in the rapid adoption of AI within enterprises.
AIR was co-founded by CEO Yair Saban and CTO Niv Hoffman, both veterans of Israel’s elite Unit 8200 intelligence corps. Their deep cybersecurity expertise is being applied to a novel problem: the tools AI agents use lack the rigorous verification historically applied to traditional software components. This creates significant risk as these agents evolve to resemble operating systems within company networks.
The company secured its funding in two closely timed seed rounds. A $10 million round was led by Sequoia, quickly followed by a $40 million round led by Greenoaks. Notable individual investors include Zach Frankel from Cognition, Wiz co-founder Yinon Costica, and Eon co-founder Ofir Ehrlich, signaling strong industry confidence.
AIR’s platform works by discovering all active AI agents within a company’s environment. It flags unauthorized tool usage and enforces real-time security checks, screening tools against a continuously updated whitelist. The platform currently identifies and filters out approximately 27% of the add-ons it evaluates, highlighting the scale of potential risk.
The startup already serves over 20 customers, with the strongest demand coming from highly regulated sectors like financial services and pharmaceuticals. In these industries, the potential for an AI agent to access sensitive data or perform an unauthorized action carries severe compliance and security implications. AIR competes with other well-funded startups like Zenity and Noma Security.
Sequoia partner Bogomil Balkansky emphasized the complexity of the challenge, describing it as a continuous infrastructure problem rather than a one-time scanning task. AIR plans to use the new capital to expand its research and development capabilities. It will also scale its go-to-market efforts across the United States and Europe.
With approximately 40 employees currently, AIR is positioned at the intersection of two powerful trends: the exponential growth of AI agent deployment and the escalating need for robust AI-specific security measures. As companies race to integrate AI, tools like AIR’s could become essential governance components. The company’s future growth will depend on its ability to stay ahead of rapidly evolving AI toolkits and threat landscapes.
