What Prometech Group does
Prometech Group, Inc. (プロメテックグループ株式会社) is a Tokyo-based privately-held technology holding company founded in 2004 and reorganized into a holding company structure on 2023-10-01. The group develops and commercializes particle-based computational simulation software, GPU-accelerated high-performance computing (HPC) infrastructure, and computer-graphics visualization for industrial R&D customers. Its principal operating subsidiaries are Prometech Software, Inc. (CAE software R&D, sales, consulting, and visualization); GDEP Solutions, Inc. (GPU hardware sales and rentals, cloud infrastructure, GPU venture creation); Particleworks Europe S.r.l. (a jointly-controlled Italian joint venture with EnginSoft S.p.A. managing EU distribution); Prometech CG Research (academic CG research with regular SIGGRAPH/IEEE VR publications); and HPC WORLD (the only Japan-based user community for NVIDIA HPC SDK and OpenACC).
The group's underlying technology centers on the proprietary Moving Particle Simulation (MPS) method originated at the University of Tokyo by Professor Koshizuka Seiichi (now an Outside Director of the group), combined with proprietary GPU acceleration that made Prometech the first CAE vendor globally to deploy GPU code in the field. The flagship products are Particleworks (a particle-based Computational Fluid Dynamics package for free-surface flows, splashing, water spray, and structural failure simulation) and Granuleworks (a Discrete Element Method package for granular materials, released 2017), used across automotive, machinery, materials, chemical, electronics, food, consumer goods, medical, civil engineering, disaster prevention, and energy industries. Supporting offerings include the SIMUNIMA visualization software, the Prometech Cloud SaaS resource provisioning platform (grand-launched October 2024, 2025 Good Design Award winner), the RICOS Lightning AI-CAE software (delivered via the 2023 RICOS Corporation investment, IsoGCN algorithm), and the annual Prometech Simulation Conference (PSC) conference since 2012 plus the GPU UNITE event run jointly with NVIDIA.
Prometech generates revenue from a mix of (i) enterprise CAE software licenses and recurring maintenance, (ii) GPU hardware sales and rentals (GDEP Solutions), (iii) professional services including HPC consulting, simulation consulting, visualization, and movie production, and (iv) a nascent cloud subscription via Prometech Cloud. The go-to-market is primarily direct enterprise sales to large Japanese manufacturers, supplemented by regional channel partners and joint ventures in Europe (Particleworks Europe S.r.l.), Asia Pacific (SCx Solutions), Vietnam (SDE Digital Technology, signed February 2025), and defense/security (Armatus, signed August 2024), with a strategic co-development partnership with Smart Manufacturing Technology (signed June 2025) targeting electrified powertrains. The group has remained substantially self-funded across its 21-year operating history and has not publicly disclosed revenue or external funding rounds.
