Armadin

Seven months ago we came out of stealth with a clear mission to set the standard to determine if companies are secure or not. Armadin just raised $255.5 million to continue its mission to build the future of effective autonomous security. Today we're announcing our Series B, co-led by Andreessen Horowitz (a16z) and Accel. Additional investors in this round include Bain Capital Ventures (BCV), Redpoint, 8VC, Ballistic Ventures, GV (Google Ventures), IQT, Kleiner Perkins, and Menlo Ventures. AI has compressed the time between vulnerability disclosure and working exploit, and periodic penetration tests cannot keep pace. Defenders need autonomous offensive security that never stops testing. Armadin deploys a swarm of AI agents that validate kill chains as environments change and show security teams which paths to sever before an adversary uses them. This investment lets us bring that proof to more organizations, faster. Thank you to a16z and to every investor who shares our conviction that assumptions are not proof.

AI attacks won’t wait for your next assessment. Armadin launches thousands of autonomous agents across your global enterprise. Millions of targeted actions. Every attack path exposed.

Red makes blue better. That's the idea behind our partnership with CrowdStrike. At Fal.Con 2026, our CTO Travis Lanham sat down with Mike Petronaci, CrowdStrike's Head of AI Technology Strategy, to get into it. They talk about why the old approach to vulnerability management has stopped delivering security value, what it means to connect Armadin Red as the source of discovery, findings, and validation directly to the agentic SOC, and how offense and defense can finally work as one continuous loop. Full conversation coming soon. Here's a first look.
