SAIHEAT is a small bitcoin mining and computing infrastructure company whose core differentiating technology is a liquid-cooling system that captures waste heat from bitcoin mining machines and repurposes it for commercial heating uses, such as heating greenhouses or buildings. The company operates through two main activities: self-mining bitcoin at a single U.S. facility in Ohio (SAI NODE Marietta), where it runs 734 machines generating roughly 110.85 PH/s of hash rate; and selling its proprietary liquid-cooled containerized data center products, the ULTIWIT System, to external miners and computing operators. The ULTIWIT product line includes several containerized units — TANKBOX, RACKBOX, and HYDROBOX — fitted within standard 20-foot containers, plus a HEATBOX unit that routes recovered heat to end-users. SAIHEAT claims its technology achieves up to 97% thermal efficiency, effectively turning a mining facility into an electric boiler that simultaneously mines bitcoin and generates hot water for heating. Equipment sales account for roughly 69% of revenue and are lumpy and deal-dependent; a supply agreement with Nasdaq-listed miner Bitdeer was a notable recent driver. Bitcoin self-mining accounts for the remaining ~31% of revenue, with profitability driven by hash rate deployed, bitcoin price, and network difficulty. SAIHEAT's longer-term ambition is to commercialize a third revenue stream by selling recovered heat to end-users, though this has not yet generated revenue. The company is also developing liquid-cooling products targeting AI/GPU infrastructure and has an early-stage small modular reactor initiative under the HEATNUC brand.
