CLSK

Cleanspark, Inc.

A bitcoin mining company that runs dozens of data centers across the southern and western United States, contributing computing power to a mining pool in exchange for bitcoin rewards and now expanding into AI and high-performance computing hosting. It began in 2014 as an energy-software and microgrid company — the name blends "clean" for its clean-energy roots with "spark" for power — before pivoting to bitcoin mining. Its corporate shell dates back to 1987, when it was incorporated in Nevada as SmartData Corporation.
