TIS and Quantum Mesh Collaboration

TIS Inc., part of the TIS Intec Group based in Shinjuku, Tokyo, has recently announced a partnership with Quantum Mesh Inc., headquartered in Chuo, Tokyo. This collaboration aims to develop and deploy AI infrastructure services leveraging Quantum Mesh's decentralized edge data centers and their immersion cooling system known as "KAMUI". This initiative is set to commence in October 2025 and hopes to address increasing demands for GPU servers, as well as challenges posed by rising energy costs and high load on data centers.

As enterprises increasingly adopt AI for operational efficiency and new business ventures, the necessity for high-performance GPU servers has surged, leading to a projected growth in the housing service market for these servers. It is estimated that this market will expand rapidly, achieving an average growth rate of 73.1% annually until 2029, with performance expectations seeing a fifteen-fold increase over five years. However, the substantial energy consumption and heat generation from these high-performance servers necessitate innovative cooling solutions. Traditional cooling methods are expected to transform, paving the way for advanced technologies such as water cooling and immersion cooling, the latter of which significantly enhances cooling efficiency and reduces operational costs.

TIS boasts a cutting-edge urban data center, spanning approximately 20,000 square meters in Tokyo. This facility employs a seismic-resistant design and the latest technology, serving a broad range of clients focused mainly on enterprise solutions. Despite their extensive operational success, TIS recognizes the urgent need to enhance the value proposition of their data center services in anticipation of the AI age, especially through the acquisition of new clients who leverage AI technologies.

Meanwhile, Quantum Mesh is a startup that specializes in the development and operation of decentralized edge data centers. In March 2025, they commercialized their innovative cooling solution, the immersion cooling system "KAMUI", which absorbs heat directly from GPU servers through immersion in a cooling liquid. This marks a significant development, as it is the first system of its kind to achieve commercialization in the country. Though they have strong technological assets, Quantum Mesh is also focused on scaling operations to meet growing market demands.

Recognizing the urgent challenges posed by data center loads and energy costs, TIS and Quantum Mesh aim to provide highly efficient AI infrastructure services. This includes testing the KAMUI immersion cooling system with its first users from November 2025, establishing proof of concepts (PoC) that investigate system performance and operational verification. This structured approach will inform the final product development slated for summer 2026.

Overview of the Collaboration

The collaboration will entail the following key initiatives:

• - Joint development and provision of new services leveraging TIS and Quantum Mesh's hybrid data center capabilities.
• - Collaborative maintenance and operation of the decentralized edge data centers.
• - Expansion of decentralized edge data center installations.
• - Joint development and sales of the KAMUI immersion cooling system.
• - Development of secure data service platforms.

PoC Details

A comprehensive PoC program is set to commence in November 2025, lasting for approximately six months. The PoC will center around the integration and operational testing of the immersion cooling system KAMUI, targeting performance metrics that will subsequently dictate the broader rollout of new services.

New Service Overview

The goal is to create a robust AI infrastructure service that supports enterprises deploying AI applications for efficiency and growth. Considering future demands for secure private AI training, TIS and Quantum Mesh plan to build a hybrid model that optimally incorporates both entities’ data centers.

Future Directions

The first phase of collaboration will strategically integrate TIS's data center with Quantum Mesh’s facilities, promoting the development of AI-based service offerings and responding to enterprise needs effectively. Future plans involve collaborative expansion of decentralized data centers and further development of the KAMUI cooling system.

About KAMUI

KAMUI represents a breakthrough in cooling technology, utilizing a closed-loop, single-phase immersion cooling system that effectively manages heat generation by immersing the servers in a specially engineered liquid. The system achieves an operationally stable temperature between 14°C and 18°C year-round, which results in significant energy savings—operating with power requirements less than one-tenth that of conventional air-conditioning systems. The overall Data Center achieves a PUE (Power Usage Effectiveness) rating between 1.03 and 1.04, making it one of the most efficient systems in the world.

About Digital Infrastructure Offering Services

These services are tailored for companies initiating IT services or modernizing IT infrastructure. TIS combines various strategies from infrastructure design to operational management, allowing businesses to focus on application development while minimizing infrastructural burdens.
