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.

OpenHands provides a cloud agent platform that integrates with GitHub, GitLab, Bitbucket, Slack, and Jira to offload repetitive software-development tasks such as dependency upgrades, unit-test creation, merge-conflict resolution, and vulnerability sweeps. The system is enterprise-secure, running each agent in an isolated Docker sandbox and offering role-based access control, audit trails, and flexible SaaS or self-hosted deployment. Because the platform is model-agnostic, customers can bring their own large-language-model and avoid vendor lock-in while routing tasks to the best model for the job. OpenHands has quickly gained traction in the developer-AI community, accumulating more than 60,000 GitHub stars, 7,000 forks, and 4 million downloads, with engineers at firms such as AMD, Apple, Google, Amazon, and Netflix already experimenting with the code. Early enterprise users report up to a 50 percent reduction in code-maintenance backlogs and vulnerability-resolution times cut from days to minutes. A new strategic collaboration with AMD will optimize the open-source Lemonade Server for AMD hardware to further enhance agent performance and privacy. Fuelled by its recent Series A financing, the company plans to accelerate product development, expand enterprise features, and support large-scale code-automation projects worldwide.

SettleMint offers a low-code platform that reduces blockchain development complexity and lets teams create decentralized applications in weeks rather than months. The product is chain-agnostic and supports both permissioned and permissionless networks. Customers include a university in Indonesia (blockchain voting), the state of Jharkhand in India (seed supply-chain tracking) and banks using the platform to tokenize securities. Headquartered in Belgium, the company also has teams in the UAE, Singapore and India. SettleMint says it has been operating for about six years and describes itself as capital efficient; it had raised €7.6 million prior to its latest round. The team is roughly 55 people and plans to add about 60 hires. With the new capital the company aims to deepen its presence in Europe, the Middle East and Asia Pacific and to test the U.S. market, while collaborating with Fujitsu to enter Japan. SettleMint offers a scalable low-code, infrastructure-agnostic blockchain middleware that lets enterprise developers quickly create and deploy blockchain-based applications. Its platform (including SettleMint APIs / CertiMint) aims to remove vendor lock-in and abstract away blockchain complexity for developers and decision-makers. The solution is designed to be highly accessible to developers and supports rapid commercial deployment. SettleMint reports use across more than 30 public- and private-sector use cases, several of which have exited the lab. The company has partnered with KPN for distribution and API-store integration. The latest financing will support international expansion and commercialisation efforts across Europe, MEA, and APAC. The round increases the company’s total funding to €5.5 million. SettleMint develops middleware and applications that leverage distributed ledger technology for fintech use cases. The company released SettleMint Ballot Box, an application demonstrating secure and immutable recording of votes on the bitcoin blockchain. It is also advancing work on property titling technology and procedures to simplify KYC compliance. SettleMint will represent t0.com as that firm seeks to expand its European presence. The company attracted investment interest from Medici Ventures, which cited SettleMint’s early blockchain voting work and broader product progress.

QunaSys gathers research scientists to develop algorithms that maximize the potential of quantum computing and to produce applications usable without special expertise. The company is active in quantum-computing R&D and manages the QPARC industry consortium to help partners learn about quantum computers. Its technical focus includes quantum-chemical calculations and quantum machine learning, as well as efforts to fuse those fields. Through its work QunaSys aims to apply research toward practical new applications, including in materials discovery. The company says these capabilities can reduce time and cost of R&D and facilitate more efficient exploration of low-environmental-impact materials. QunaSys intends to deepen collaborations with industrial partners to tackle major manufacturing challenges. QunaSys develops algorithms and chemical software to accelerate applicability of quantum computing, centered on Qamuy, its cloud-accessible quantum computing development solution that runs on multiple platforms. The company targets chemical-related industries with use cases including energy analysis, molecular structure optimization and sustainable materials. QunaSys plans to use new funding to accelerate development of more usable quantum computing chemical software and to expand overseas by opening a European base. Led by CEO Tennin Yan, the firm has expanded its R&D and business development activities since 2019 and reports record business growth. In July 2020 QunaSys established QPARC, a Japanese consortium that has grown to include more than 50 companies (including ENEOS Holding and JSR Corporation) to study quantum computing applicability.
