About company
Twenty

Twenty builds and scales the software and capabilities of modern cyber conflict, industrializing the American arsenal for the war of now.

Our mission is to deliver industrial-scale cyber capabilities, ensuring the U.S. and its allies are able to deter and defeat their adversaries. We are not theorizing or simulating — we are building the capabilities that matter in today’s fight, the ones our adversaries already fear and our mission partners urgently need.

Backed by Caffeinated Capital, General Catalyst, and In-Q-Tel, we move at the pace that conflict demands. Our founding team represents the top 0.1% of cyber operators — those entrusted with the nation’s hardest missions — and we’ve led cyber warfare, not just written about it.

We don’t settle for incremental gains — we redefine what’s possible. Our products encode elite tradecraft directly into the system, transforming workflows that once took weeks into automated, continuous operations across hundreds of targets simultaneously. This is not about being 20% better; it’s about being 100X better.
