# Cathedral raises $160M at $1.4B valuation for AI military cyber operations

> Cathedral has emerged with $160 million in fresh funding at a $1.4 billion valuation, an unusually large raise for a company that is still largely in stealth. The round was co led by Andreessen Horowitz and Sequoia Capital, both taking board seats, and the startup was founded by four former Department of Government Efficiency staffers, including Gavin Kliger, who recently served as chief data officer at the Pentagon. The company's mission is pointed, using AI to expand US military cyber capabilities across both offensive and defensive operations against adversaries such as China. Cathedral is also looking to secure dedicated compute, either by acquiring a data center or partnering with one, to run those workloads at scale. The raise captures how quickly defense has become a magnet for AI capital and talent, with founders moving from government service straight into venture backed national security work. A billion dollar plus valuation for a stealth startup with a heavy government orientation signals real conviction from top tier investors, and also raises familiar questions about oversight when private companies build offensive cyber tools for the state.
