Firmus Technologies builds and operates data centers designed from the ground up to handle AI workloads, with advanced power and cooling systems optimized for high-performance computing. Their facilities are purpose-built for AI rather than being traditional data centers retrofitted with graphics processors.

Firmus emphasizes operational efficiency and energy sustainability in its data center design, incorporating advanced power and cooling technologies to minimize environmental impact while maximizing compute density. Their facilities are designed from the ground up for AI workloads rather than being retrofitted from general-purpose data centers.

The surge in demand for AI training and inference capacity has created a massive need for purpose-built AI data centers, positioning Firmus as part of the new wave of AI-native infrastructure providers. Firmus raised nearly $550M in capital from Nvidia and others in September 2025. Soon after, they raised $10B in debt in January 2026 to fund Project Southgate, aimed to deploy infrastructure for sovereign AI in Australia.
