About

Founded in 2024 in San Francisco by Kevin Mandia (CEO, ex-Mandiant founder), Travis Lanham (CTO), Evan Peña (Chief Offensive Security Officer), and David Slater (Chief Architect), Armadin builds the 'ultimate attacker' — an AI-powered red teaming platform that uses specialized AI agents in an agentic swarm to continuously reason, plan, and adapt like advanced human threat actors. The platform provides continuous offensive security testing and remediation guidance, giving enterprises and government agencies decision-grade proof of exploitable risk. Armadin raised a record-breaking $189.9M in combined Seed and Series A funding led by Accel, with participation from Google Ventures, Kleiner Perkins, Menlo Ventures, In-Q-Tel, 8VC, and Ballistic Ventures.
