AIR Raises $50 Million to Vet AI Agent Skills as 27% of Add-Ons Fail Checks

Summary
$50 million in two seed rounds has brought AIR out of stealth, with the AI security startup targeting the tools, plugins and MCP servers used by enterprise AI agents.
AIR says companies need supply-chain oversight as agents gain broader access to databases, internal systems and the internet, creating risks from poisoned content and compromised add-ons rather than direct attacks.
Its platform discovers agents across a company, flags unapproved AI use, intercepts actions such as loading skills or fetching web content, and checks tools against a continuously updated whitelist; AIR says 27% of online add-ons it reviews are blocked.
More than 20 customers have signed on so far, about a quarter of them large enterprises, with strongest demand in regulated sectors including finance and pharmaceuticals.
Sequoia led AIR's $10 million first seed round and Greenoaks led a $40 million second round, funding hiring and U.S.-Europe expansion in a crowded market where Zenity recently raised $125 million and Noma raised $100 million.
