Three South Korean startups join Japan’s ai& neocloud venture, supplying AI infrastructure software, NPU servers, and an LLM for its Tokyo data center and AI inference services.
Three South Korean startups: MOREH, Motif Technologies, and Rebellions have joined the operations of Japanese neocloud company ai&, expanding their presence in Japan’s growing artificial intelligence infrastructure market. The collaboration covers AI infrastructure software, specialised AI chips, and large language models.
Launched in March 2026, ai& provides cloud-based AI inference services and platforms for developing AI applications. The company is building an AI data center in Tokyo and plans to expand its capacity to 40 megawatts as it develops infrastructure for AI workloads.

MOREH is supplying its Token Factory operating system to manage the Tokyo data center’s heterogeneous computing environment. The facility uses Nvidia’s B300 GPUs and AMD’s MI355X GPUs, requiring software capable of allocating computing workloads across different processors. MOREH has supplied the system to ai& since April, marking its first overseas Token Factory OS contract.
Rebellions is participating as an AI chip supplier for the data center and will provide 100 racks of servers equipped with its second-generation REBEL100 neural processing units (NPUs). The arrangement marks the company’s first rack-scale product sales revenue in Japan, expanding beyond its earlier exports of individual NPU cards and servers.
Motif Technologies is contributing its Motif 3 large language model to ai&’s AI inference platform. The model is among 11 AI models available to ai& customers, alongside models such as Google’s Gemma and OpenAI’s gpt-oss. Motif Technologies is a subsidiary of MOREH and developed Motif 3 through South Korea’s government-backed programme for domestic AI foundation models.

The companies expect their participation in the ai& project to provide a reference for expanding their businesses in Japan. MOREH CEO Cho Kang-won said demand for AI inference infrastructure is growing in Japanese industries and services, increasing the importance of diverse AI chips and software.
The partnership also reflects the growing use of heterogeneous computing, where different types of processors are combined to support AI workloads. Through the collaboration, the Korean companies aim to establish a stronger foothold in Japan’s AI infrastructure and services market.
