IREN

IREN builds and operates grid-connected data centres running on 100% renewable energy, hosting both AI and Bitcoin workloads. The company's infrastructure spans North America, with operations in British Columbia, Canada, where its Bitcoin mining business began using hydroelectric power. It owns and runs its facilities end to end, from site development and power-capacity procurement through to day-to-day operations.

Two business lines sit on top of that infrastructure. AI Cloud services deliver large-scale GPU cluster capacity for demanding AI training and inference workloads. Bitcoin mining remains the original business. Secured power capacity across the facilities underpins both, and dedicated support teams provide 24/7 coverage.

The technical domains in play include GPU compute clusters, data centre design and operations, high-performance computing, renewable and hydroelectric energy, and site development. The working culture is hands-on and operationally focused, reflecting a vertically integrated model in which the company runs its own kit rather than leasing capacity from others.
