What SAIHEAT does
SAIHEAT Limited (NASDAQ: SAIH) is a Cayman Islands-incorporated, Singapore-headquartered distributed computing power operator that operates three distinct business lines. First, its TOKEN platform provides enterprise-level token-based API access to multiple open-source foundation models (Kimi, GLM, DeepSeek, MiniMax, MiMo), with publicly disclosed per-token pricing across input, output, and cache tiers and proprietary inference optimization for low-latency, high-concurrency workloads. Second, its ATOMIC platform delivers integrated nuclear engineering design and analysis software covering six segments (reactor physics, thermal-hydraulic analysis, nuclear safety analysis, probabilistic safety assessment, system simulation, and radiation protection) for both large Light Water Reactors and Small Modular Reactors, marketed to nuclear power operators and SMR developers. Third, SAIHEAT sells liquid-cooling container hardware for data center construction and holds patents on a Waste Heat Recovery System (chip cooling, valve-controlled heat distribution) and a Control Rod Drive Mechanism for SMRs.
The company became publicly traded in May 2022 through a merger with TradeUP Global Corporation (formerly known as SAI.TECH Global Corporation) and received IAEA approval as an SMR vendor in June 2025. It employs 11-50 staff across offices in Singapore, Marietta (Ohio, USA), and Beijing. Revenue is generated through three mechanics: usage-based token pricing for AI inference, subscription/consulting for nuclear design software, and one-time hardware sales for liquid-cooling containers. Named enterprise customers are limited; Bitdeer Technologies Group is the only disclosed buyer of hardware (40MW liquid-cooling contract, March 2025). The go-to-market is enterprise field sales with consultation-driven onboarding via [email protected] and [email protected], supplemented by token-based API access for AI customers.
