GoKawiilMandiant founder's Armadin raises $255.5M Series B at $2.5B valuation
Kevin Mandia's new security startup Armadin has closed a $255.5 million Series B round at a valuation exceeding $2.5 billion, led by Andreessen Horowitz and Accel with participation from Bain Capital Ventures, Redpoint, 8VC, Ballistic Ventures, Google Ventures, In-Q-Tel, Kleiner Perkins, and Menlo Ventures. The round follows a $190 million Series A just six months earlier, bringing Armadin's total funding to over $445 million. The company builds always-on 'agentic swarms' that continuously probe enterprise systems for vulnerabilities, chaining weaknesses together in a manner meant to replicate how attackers might exploit them.
