Raised a record-breaking $189.9M combined seed and Series A (announced 2026-03-10) led by Accel with Google Ventures, Kleiner Perkins, Menlo Ventures, and In-Q-Tel, the largest combined seed/Series A in cybersecurity history per the company.
CEO Kevin Mandia brings deep, pre-existing relationships with major enterprises, federal law enforcement, and defense organizations, though specific new-product deployments were not disclosed.
Record-setting $189.9M raise closed 2026-03-10, reflecting an unusually strong investor and industry response for a company only founded in 2025.
AI-agent-driven, continuous red-teaming at world-class-team standard is a meaningful step up from periodic manual red-team engagements, though automated red-teaming is an increasingly competitive category.
No independent, third-party efficacy validation was located yet; claims are from launch coverage and leadership reputation.
Preparing organizations for AI-driven, machine-speed attacks is a rapidly rising priority across enterprise and government security programs.
Why CISOs Should Care
Armadin automates red-teaming with AI agents trained to a world-class red-team standard, giving security teams continuous, real-time insight into exploitable vulnerabilities from an attacker's perspective at a scale manual red teams cannot match.
What Makes It Different
Led by Kevin Mandia (former Mandiant/FireEye CEO), Armadin combines an unusually large, record-setting combined seed-and-Series-A raise with deep, longstanding relationships across enterprise, federal law enforcement, and defense customers built over Mandia's career.
