Twenty, an AI-powered cybersecurity firm serving US military operations, raised $100 million in Series B funding led by Accel Partners. The company now carries a $1 billion valuation.

Twenty develops artificial intelligence tools designed to assist US military hackers in penetrating adversary computer networks. The startup distinguishes itself through explicit focus on offensive cyber capabilities—an uncommon market position for venture-backed firms. Accel Partners led the funding round, backing the company's expansion in defense technology. Twenty joins a small cohort of startups openly marketing offensive cyber tools to government clients. The company operates within the US defense contracting space, where demand for advanced cyber warfare capabilities continues rising amid geopolitical tensions. Twenty's AI platform aims to automate and enhance penetration testing and network exploitation techniques used by military cyber units. The $1 billion valuation reflects investor confidence in defense technology markets, particularly as military organizations prioritize cyber operations and AI-driven security tools. Twenty's funding round occurs amid broader venture capital interest in defense-focused startups addressing modernization priorities within the Department of Defense.
