a16z announced on October 1 that it is leading Armadin's Series B. The round size and valuation were not disclosed.

Armadin was founded by Kevin Mandia, who founded Mandiant, the incident-response firm; his co-founders come from Google's security products and Mandiant's red team. The company's product, Armadin Red, is positioned as an autonomous AI red-team platform that uses agent swarms to continuously test enterprise environments.

The information comes from a16z's own investment announcement. Whether the round has closed, and its size and valuation, remain unknown, and the product's capabilities are the company's description; watch for independent disclosure from Armadin or Mandia.
