Twenty Technologies raised a $100 million Series B at a $1 billion valuation, becoming what it describes as America's first venture-backed cyber-warfare company. The round was led by Accel, with participation from Point72 Ventures, Caffeinated Capital, and Friends & Family Capital, lifting Twenty's total capital raised to $138 million. The Arlington, Virginia company builds AI-enabled systems for automated offensive cyber operations sold to the U.S. military and intelligence agencies.
The category is the headline. For years, offensive cyber was considered too sensitive and too government-bound for venture capital -- the buyer was opaque, the work classified, the exits unclear. Twenty's billion-dollar mark, led by a generalist tier-one fund in Accel, signals that the same shift that made Anduril and Palantir investable has now reached the most sensitive corner of national security.

The timing fits a record year. 2026 defense-tech funding has crossed an all-time high as investors grow confident that the national-security apparatus is a durable, well-funded customer and that strategic acquirers -- and now public markets -- offer real exits. Twenty arrives alongside a wave of defense and sovereign-security rounds, from Dream's $3 billion sovereign-cyber mark to a broad surge in dual-use startups.
