Twenty, an Arlington, Virginia-based startup billing itself as America's first VC-backed cyber-warfare company, raised a $100 million Series B at a $1 billion valuation. The company builds AI-enabled offensive cyber systems for US military and intelligence customers -- a category that until recently lived inside government contractors and classified programs, not venture portfolios.
The round is part of the broader defense-tech wave that Anduril and Palantir normalized: well-funded, software-first companies selling directly to the national-security apparatus, valued like growth-stage tech rather than legacy primes. A billion-dollar mark at Series B for an offensive-cyber company shows how far investor appetite for dual-use and defense has expanded.

For founders, Twenty is a marker of where defense capital is flowing next. The first wave funded autonomy, sensing, and hardware; offensive cyber is the new frontier, and the buyers -- DoD and the intelligence community -- have budgets that dwarf most commercial markets.
