Rhombus Power

Rhombus Power is a defense technology company founded in 2011 and led by CEO Dr. Anshuman Roy, headquartered in Mountain View, California. Its flagship Guardian platform is an AI decision-advantage system that fuses multi-domain data to predict threats — from missile launches to regional instability — at strategic, operational, and tactical levels, and to support Pentagon resourcing and budget building. Its Ambient product is marketed as a 'digital nervous system' of AI predictions.

The company says Guardian processes over one trillion data points per day from thousands of commercial streams. Rhombus works exclusively with the United States and its allies and maintains branches in Japan, Taiwan, India, the Philippines, and South Korea. It has been widely reported to have predicted Russia's 2022 offensive in Ukraine months ahead of the invasion — a claim that originates with the company.

Rhombus is nearing the end of a five-year Department of Defense contract with a roughly 200 million dollar ceiling and is in talks to extend it, with a federal award recorded on September 26, 2025. Its funding is largely undisclosed and it has no public valuation. Its data-scale and predictive-accuracy claims are difficult to verify independently, and it is distinct from the unrelated Rhombus Systems physical-security company.
