Twenty, a startup that builds AI-driven tools designed to automate offensive cyber operations for US military and intelligence agencies, has reportedly reached a $1 billion valuation. For a company that didn’t even exist before 2024 and only emerged from stealth mode in November 2025, that’s a remarkably fast ascent into unicorn territory.
From stealth to unicorn in record time
Twenty was founded in 2024 and is headquartered in Arlington, Virginia. The company came out of stealth in November 2025, simultaneously announcing a $38 million Series A funding round led by Caffeinated Capital.
General Catalyst participated in the round, as did In-Q-Tel, the CIA’s nonprofit venture arm.
Twenty’s founding team comes from elite cyber units. The company’s core product focuses on agentic AI systems, meaning autonomous software agents capable of conducting offensive cyber operations at industrial scale. Twenty’s pitch is that its tools can handle numerous simultaneous targets.
