Value proposition

Enables enterprises to run ultra-large LLM inference (up to 700B parameters) on a single low-power PCIe card at ~240W using mature 28nm process and DDR4 memory, eliminating the need for expensive GPU clusters.

Products and solutions

HTX301 PCIe AI accelerator card (6 chips, 384GB memory, 700B LLM inference at 240W); HyperThought LPU IP platform (for custom AI chip design); EdgeThought IP (on-device LLM inference accelerator); Skygenie Auto Concept (automotive AI); AI compiler and runtime software stack

Unique value

Only company offering 700B-parameter LLM inference on a single PCIe card at just 240W using mature 28nm process and commodity DDR4/DDR5 memory — no HBM, no advanced node, no GPU cluster required.

Target customer

IC design houses, semiconductor companies, device manufacturers, system integrators, and enterprises needing on-premise AI inference

Industries served

Semiconductor, Automotive (smart cockpits), Edge AI / IoT, Enterprise AI inference, Consumer electronics

Technology advantage

Proprietary LPU (Language Processing Unit) architecture with Prefill/Decode disaggregation; 10+ years of compiler/runtime expertise for AI SoCs; LISA v3 instruction set architecture; 28nm process avoids geopolitical fab restrictions; DDR4/DDR5 instead of expensive HBM; 0.5 TOPS delivers 30 tokens/s single-core performance.

How they differentiate

Focuses on inference-only efficiency rather than general-purpose GPU compute; uses mature 28nm process and DDR4 memory for cost advantage; Prefill/Decode disaggregation architecture optimized specifically for LLM inference; IP licensing model enables custom chip integration; avoids HBM supply constraints and geopolitical fab restrictions.

Main competitors

NVIDIA (GPU inference); FuriosaAI (Korean AI inference accelerators); Quadric (AI accelerator IP)

Key partnerships

JFE Shoji Electronics (Japan distribution and AI acceleration solutions); Inventec and VicOne (GenAI cybersecurity for smart cockpits at Tokyo Automotive World); Qualcomm (Innovate in Taiwan Challenge); Cadence (IP strategy collaboration)

Notable customers

Inventec (TWSE: 2356); VicOne (Trend Micro subsidiary); JFE Shoji Electronics

Major milestones

2024-06: Launched EdgeThought IP (on-device LLM accelerator); 2025-05: Launched HyperThought LPU IP platform; 2025-05: Closed $18M funding round with TGVest and Taiwania Capital; 2025-09: Partnered with JFE Shoji Electronics for Japan market; 2025-12: HyperThought won "Best IP/Processor of the Year" and "Most Promising Product" at EE Awards Asia 2025; 2026-04: Announced HTX301 PCIe AI accelerator (700B LLM at 240W)

Growth metrics

1,040 LinkedIn followers; 11-50 employees; offices in Taipei and Hsinchu

Market positioning

Niche disruptor in AI inference hardware, positioning as a cost-effective alternative to NVIDIA GPU clusters for on-premise enterprise LLM deployment, with particular strength in edge AI and automotive applications.

Geographic focus

Taiwan (home base), Japan (via JFE Shoji partnership), global enterprise market

Patents and IP

HyperThought LPU IP platform; EdgeThought IP; LISA v3 (third-generation language instruction set architecture); MCLinker and ONNC compiler technologies
