JIJ builds a quantum- and AI-enabled optimization platform and related software (including the JijZept suite, OpenJij, and the Qamomile quantum programming language) to support the full optimization lifecycle from model formulation through execution and continuous improvement. The company has developed more than 60 use cases across industries such as manufacturing, transportation, telecommunications, energy, logistics, materials development, and the public sector. JijZept AI entered beta in early 2026 and is being developed into a cloud-based AI agent service with an SDK and sandbox for AI-assisted modeling, numerical experiments, and eventual support for quantum programming. JIJ is also developing middleware for gate-based quantum computing through government-backed R&D and participates in global quantum industry ecosystems. The company plans to expand enterprise deployments of mathematical optimization, strengthen research and engineering teams, and accelerate international growth; it established JIJ Europe Ltd. in 2025 and JIJ GmbH in 2026 and is scaling activities in the United States. Financially, JIJ closed this equity financing of JPY 840 million (approx. US$5.2 million) to fund product development, deployment scaling, and global expansion.
