What SAI.TECH does
SAI.TECH Global Corporation (operating as SAIHEAT, Nasdaq: SAIH) is a Singapore-headquartered, publicly listed sustainable computing and clean-technology company that designs, manufactures and operates liquid-cooled Bitcoin mining and AI/HPC data center infrastructure, with proprietary systems that recover waste heat from computing chips for residential, commercial, agricultural and industrial heating applications. The core technology is a patented liquid cooling architecture that replaces air-cooling fans with circulation pumps and recovers over 90% of ASIC chip waste heat as 60-70°C hot water, marketed under the SAIHUB brand and packaged as modular container systems including WITBOX (computing containers), HEATBOX (heat recovery/regulation) and USERBOX (heating-end delivery). Hardware products span the HYDROBOX, RACKBOX and TANKBOX lines for Bitcoin mining (priced $14.5K-$99.8K per unit) and the RACKBOX A1, an AI/HPC container supporting 32 NVIDIA HGX H100/H200 servers with a reported PUE of 1.027.
The company generates revenue through a mix of one-time hardware unit sales, recurring BTC joint-mining hosting services operated from fully compliant U.S. facilities, BTC cloud mining subscriptions, and managed energy digitization and monetization solutions for energy asset owners. Operations span U.S. R&D and mining sites (SAI NODE Marietta, Ohio; Chesterland distribution center), Singapore headquarters, a Beijing office, and a Mexico mining deployment, with a wholly owned subsidiary BOLTBIT (BoltGPU AI cloud, BoltSAT BTC cloud, SATX mobile app) extending the company into AI infrastructure and Lightning Network services and an emerging HEATNUC/ATOMIC line targeting Small Modular Reactor integration.
The go-to-market combines enterprise/field sales for joint-mining products and large deployments with self-serve product pages for SMB and individual hardware buyers; distribution is global via direct sales channels (email, phone, WhatsApp, Telegram) and the corporate website. Customers span BTC mining operators, energy and gas companies seeking monetization of stranded power, AI/HPC computing firms needing sustainable GPU infrastructure, and buildings/facilities in cold climates that can absorb recovered heat.
