Twenty, a startup that builds end-to-end AI-enabled offensive cyber systems for the US military and its allies, closed a $100 million Series B led by Accel at a $1 billion valuation, with participation from Friends & Family Capital, Point72 Ventures and Caffeinated Capital. The round brings total funding to $138 million for the Arlington, Virginia company, which was founded just in 2024.
Twenty's pitch is to 'industrialize' offensive cyber operations -- giving warfighters the speed and scale to deter adversaries while keeping human judgment at the center of mission execution. The new capital is earmarked for research and engineering to scale those AI-enabled capabilities for the Defense Department and the intelligence community.

The round is a marker for how far defense tech has come as a venture category. A two-year-old company reaching unicorn status on the strength of offensive cyber -- with a top-tier firm like Accel leading -- shows investors are now willing to underwrite software-defined warfare alongside the drones, autonomy and hardware that defined the first wave of the defense-tech boom.
