AIR: The Supply Chain Watchdog for AI Agents

A stealth startup from Unit 8200 veterans raises $50M to vet the skills, plug-ins, and MCP servers that AI agents use.

The news

AIR, an AI security startup founded by Yair Saban (CEO) and Niv Hoffman (CTO) — veterans of Israel's Unit 8200 intelligence corps — is coming out of stealth with $50 million raised across two seed rounds. The first round raised $10M led by Sequoia; the second raised $40M led by Greenoaks, with participation from Swish, Netz, Cognition president Zach Frankel, Wiz co-founder Yinon Costica, Eon co-founder Ofir Ehrlich, and others.

AIR's thesis: as companies give AI agents access to more of their systems, a software supply chain is forming around the tooling agents use — skills, plug-ins, MCP servers, and add-ons that let them interact with the internet. AIR offers a platform that discovers agents running inside companies, continuously vets the skills and components those agents use, and blocks interactions that don't pass security criteria. It also runs a marketplace of vetted add-ons and skills.

Why it matters

The analogy Saban draws is the killer detail. In the early 2000s, drivers didn't need to be signed — today every driver you install shows a signature because it loads code into the kernel. "You don't have that with skills or plug-ins or MCPs," he says, "and it's a shame, because it's the same mechanism, it's the same lesson, but we haven't learned it."

That's the core insight: AI agents are becoming like operating systems, but the software they load isn't getting the oversight we give to drivers or applications. The attack surface is real — as agents work autonomously across databases and connect to the internet, attackers can poison the content an agent consumes rather than attacking it directly. That's a fundamentally different threat model than traditional endpoint security.

The $50M at seed stage, with two rounds closing within weeks of each other, signals how hot this category is getting. As agentic AI moves from demo to production, the "who vets the agent's tools" question becomes existential for enterprises. AIR is betting that the answer is a dedicated security layer — and the funding suggests investors agree the window is now.
