Bitcoin mining on 100% carbon-free Energy

It’s all about sustainability

Sazmining partners exclusively with best-in-class, carbon-free data centers. Together, we maximize capacity and connect facilities to our global network of Bitcoin miners.

From Midwest beginnings to global frontiers

It started in Wisconsin.

In January 2023, we launched our first data center and reached full capacity in less than three months. Wisconsin validated the BMaaS model and proved that what we were building was real. After three years of successful operations, we retired it in January 2026, proud of everything it stood for.

In September 2023, we expanded to Paraguay, scaling from 6 MW to 9 MW to meet rising demand.

By January 2025, we set up shop in Norway, our most advanced site yet, powered by 99% carbon-free energy and pioneering heat-reuse technology.

In September 2025, we established a 5 MW hydropowered data center in Ethiopia, with the potential to expand to 20 MW, deepening our commitment to sustainable growth in emerging markets.

In February 2026, we opened our second U.S. data center in South Dakota, carrying forward the pioneering spirit that Wisconsin started, and signaling where we're headed next.

With 17.5 MW under management and growing, we’re proof that Bitcoin mining and sustainability can thrive together
