DateStageInvestorsRaisedDeal Summary
Jan 2026Undisclosed stage-$165MArmadin Security, founded by cybersecurity veteran Kevin Mandia (former Mandiant CEO), is an AI-native cybersecurity company based in San Francisco, developing an autonomous platform to defend against AI-driven 'Hyperattacks'—coordinated, machine-speed cyber campaigns. The platform features an 'agentic attacker swarm,' a network of AI agents that simulate advanced threats to identify vulnerabilities at machine speed, enabling proactive defense without human intervention. Co-founders include CTO Travis Lanham (ex-Google Cloud Security), Evan Peña (ex-Mandiant), and David Slater (ex-Google SecOps). In March 2026, Armadin raised a record-breaking $189.9 million in combined Seed and Series A funding, led by Accel with participation from Google Ventures, Kleiner Perkins, Menlo Ventures, In-Q-Tel, and follow-on investments from 8VC and Ballistic Ventures. This marks the largest such early-stage round in cybersecurity history. Funds will expand the AI-driven security platform, accelerate R&D in autonomous models, scale operations for enterprises, and hire across engineering and security research teams. Armadin positions itself to counter the shift where AI lowers barriers for sophisticated attacks, providing organizations with continuous, nation-state-level threat simulation. The round reflects strong investor confidence in Mandia's expertise and the team's AI capabilities amid rising AI-powered threats.
Dec 2025SeedBallistic Ventures (lead); Lightspeed Venture Partners$24MArmadin is an AI-native cybersecurity platform founded by Kevin Mandia (CEO), Travis Lanham (CTO), David Slater, and Evan Peña that specializes in autonomous red teaming and offensive security testing. The platform deploys an agentic attacker swarm—a fleet of specialized AI agents that continuously reason, plan, and adapt to simulate real adversaries and identify exploitable vulnerabilities at machine speed, addressing the emerging threat of AI-driven hyperattacks that move faster than human defenders can respond. The company was first announced quietly in late 2025 with an initial seed of $24 million from Ballistic Ventures (co-founded by Mandia). On March 10, 2026, Armadin announced a combined Seed and Series A funding round totaling $189.9 million, representing the largest early-stage cybersecurity raise on record. The Series A was led by Accel with participation from Google Ventures, Kleiner Perkins, Menlo Ventures, and In-Q-Tel, alongside follow-on support from 8VC and Ballistic Ventures. The capital will be used to expand the platform, accelerate AI-driven security research and development, and scale operations to support enterprises defending against evolving cyber threats. Insiders suggest the company's valuation exceeds $700 million, though the official valuation remains undisclosed in all public filings and announcements.
