Data Holdings is a Milwaukee-based colocation and cloud services provider notable as a subsidiary of the Potawatomi Business Development Corporation, making it one of the only tribally-owned data center operators in the United States, with its flagship facility built on Native-owned land. As of 2026, the company operates two physical Wisconsin facilities it owns and runs itself: a purpose-built, LEED Gold-certified flagship data center in Milwaukee and a smaller disaster-recovery-oriented facility in Eau Claire, together serving Midwest customers including financial services firms, casinos, and Fortune 500 companies. The Milwaukee site is a two-story, roughly 46,000-square-foot building with about 23,000 square feet of raised-floor colocation space and multiple megawatts of utility power, and in 2025 it became the host site for the nonprofit Milwaukee Internet Exchange (MKEIX). In 2022, Data Holdings acquired Stack41, a Data Center as a Service company that had also operated services out of a Minneapolis facility, though Data Holdings’ own current materials list only its Milwaukee and Eau Claire sites as active locations.
