Balus is an online whiteboard focused on structured thinking, developed by Levii Inc. Drawing on experience from JAXA space development and systems engineering, it is not intended to be a general-purpose design whiteboard. Instead, it helps teams “separate, connect, and summarize” complex assumptions, ideas, and relationships, turning them into structured diagrams that can be discussed and used to accelerate consensus-building and decision-making.
The product emphasizes an extremely simple UI, reducing distractions from decorative elements and overly complex features. It is suited to meetings, requirements definition, system modeling, project management, new business planning, DX initiatives, and similar scenarios. It supports real-time multi-user collaboration, allowing team members to contribute ideas and connect relationships synchronously. According to its feature table, the paid version supports viewing and editing view models, image export, external sharing, IP address restrictions, and multi-factor authentication. What makes it distinctive is that it is not just selling SaaS: it also offers structured training, systems engineering education, hands-on consulting, and organizational adoption support, making it suitable for companies that need a methodology to be implemented in practice.
Balus offers a free plan, a standard plan, and volume enterprise licenses. The free plan costs 0 yen, but only allows users to view/edit view models within 30 days of creation, and does not include image export, external sharing, or security-related features. The standard plan costs 2,000 yen per user per month before tax. Volume licenses are available for teams of 15 or more: 30,000 yen/month for up to 25 users, 50,000 yen/month for up to 50 users, and 80,000 yen/month for up to 100 users; larger deployments require a quote. New registrations receive a 14-day full-feature trial, and after the trial or paid period ends, the account automatically switches to a free license.
Its strengths are clear positioning and a simple learning curve, making it suitable for involving non-specialist members in structured discussions. It offers full Japanese-language support, local service, and case studies across manufacturing, software, government/administration, education, and other types of organizations. On the security side, it provides IP restrictions, multi-factor authentication, and a security checklist. Its limitations are that public materials do not clearly state whether it supports APIs, third-party integrations, granular permissions, compliance certifications, or self-hosting. The free plan is also quite limited, and the product and services are primarily aimed at the Japanese-language market.
Balus is suitable for Japanese companies, manufacturing R&D teams, upstream software design, DX promotion departments, consulting/training teams, and organizations that want to turn complex discussions into reusable organizational assets. Availability of access and payment from mainland China is not disclosed in the available materials, so it should be considered unknown. If Chinese-language collaboration and local payment are required, alternatives such as Miro, FigJam, ProcessOn, boardmix, and Feishu Whiteboard may be worth comparing.
