AI security startup AIR has emerged from stealth with $50 million in funding across two seed rounds to address the emerging software supply chain around AI agents. Founded by Yair Saban and Niv Hoffman, veterans of Israel’s Unit 8200 intelligence corps, AIR offers a platform that discovers AI agents within companies, continuously vets the skills, tools, and components these agents use, and blocks interactions with unapproved software or external sources. The platform also provides a marketplace of vetted add-ons and skills for AI agents.

The funding rounds were led by Sequoia (first round, $10 million) and Greenoaks (second round, $40 million), with participation from several other investors. AIR’s solution aims to provide oversight to AI agent tooling—skills, plugins, and MCP servers—akin to the security measures applied to drivers and applications in operating systems. The company argues that as AI agents gain more autonomy across enterprise systems and the internet, the risk of attackers poisoning the content consumed by these agents increases. AIR’s platform offers visibility into active agents, identifies unauthorized AI tool usage, and enforces security policies by intercepting and analyzing agent actions and checking tools against a maintained whitelist. The startup claims to filter out approximately 27% of the add-ons and skills it evaluates online. AIR positions its continuous vetting capabilities as a key differentiator in a competitive landscape that includes players like Noma Security, Zenity, Astrix Security, and Operant AI. The new capital will be primarily allocated to hiring researchers and expanding go-to-market efforts in the U.S. and Europe. Source
