Armadin

Armadin is an AI-native cybersecurity company that has developed a platform to help organizations prepare for the speed and scale of AI-driven cyber threats. The company was founded in September 2025 by CEO Kevin Mandia, Travis Lanham, Evan Peña, and David Slater. The founding team combines expertise from elite red teaming specialists with AI researchers and engineers.

Kevin Mandia is a well-known figure in the cybersecurity industry, having founded Mandiant in 2004. Mandiant became a prominent incident response and threat intelligence firm, famous for its report on cyber attacks by a unit of China's People's Liberation Army. After being acquired by FireEye in 2014 and later spun out, Mandiant was sold to Google for $5.4 billion in 2022. Mandia's co-founder, Travis Lanham, is a former Google Cloud security leader who managed technical strategy for large-scale security systems at Google following the Mandiant acquisition. This background provides Armadin with deep operational experience in how attackers operate and how to build defenses against sophisticated threats.

The company's mission is to address the challenge of "Hyperattacks"—sophisticated, multi-modal campaigns that move at machine speed and overwhelm traditional, human-led security defenses. Armadin's platform utilizes a swarm of specialized AI agents that act like an attacker, continuously reasoning, planning, and adapting to find and validate exploitable vulnerabilities and kill chains across a client's entire attack surface. Unlike traditional vulnerability scanners, these AI agents provide proof of what can be exploited, allowing organizations to proactively fix critical risks. This approach aims to reduce the time it takes to perform security tests from days to minutes.

Armadin operates on a subscription-based model, serving large enterprise clients, including Fortune 100 companies. The company has seen rapid growth, hiring over 60 employees shortly after its founding. Armadin made headlines by securing a combined $189.9 million in Seed and Series A funding, reported as the largest early-stage funding round in cybersecurity history. The funding was led by Accel, with significant participation from Google Ventures, Kleiner Perkins, Menlo Ventures, In-Q-Tel, 8VC, and Ballistic Ventures.
