Armadin uses autonomous AI agents to transform penetration testing and red-teaming, continuously finding and exploiting weaknesses in enterprise environments the same way real attackers do. The company is built to counter the emerging era of AI-driven hyperattacks by matching offensive AI with defensive offense at machine speed and scale. Armadin was co-founded in 2025 by Kevin Mandia, founder of incident response firm Mandiant (acquired by FireEye for $1B and later by Google for $5.4B), alongside Travis Lanham (CTO), Evan Pena (Chief Offensive Security Officer), and David Slater (Chief Architect). The company launched in March 2026 with $189.9M in seed and Series A funding led by Accel, with participation from Google Ventures, Kleiner Perkins, Menlo Ventures, In-Q-Tel, 8VC, and Ballistic Ventures, and is already working with Fortune 100 customers.
