SUPWAT Raises ¥200 Million to Expand Manufacturing DX Platform WALL

SUPWAT, the company behind the manufacturing DX platform WALL, announced on January 6th that it raised about ¥200 million in a pre-Series A funding round. The investment came from INSPiRE Investment through a third-party allotment of shares. This funding will go toward expanding the platform and building more features.

WALL is a digital transformation platform focused specifically on the engineering chain in manufacturing. That includes technology development, design, and production processes. The goal is to make experimental and analytical cycles faster and more efficient. It also helps capture and formalize knowledge from the factory floor that would otherwise stay in people’s heads. Companies using WALL include automotive and auto parts manufacturers, chemical and materials manufacturers, all with hundreds of billions of yen in sales. SUPWAT says these companies have been able to reduce experiment and analysis time in R&D by more than 60 percent. That is a huge reduction and shows that the platform is not just a tool but a real efficiency booster.

SUPWAT has also built advanced AI features into WALL. In September 2024, the company got a patent for technology that interprets data analysis results from machine learning models using large language models. The AI can learn accurately even from small amounts of data. At the same time, it produces results that engineers can actually understand and use. This patent technology has been part of WALL since December 2024.

The money from this round will be used to make WALL even more capable. The first phase of development started in December with a test implementation of a data lake function. Full rollout is expected in March 2026. SUPWAT also plans to support unstructured data, improve optimization algorithms, strengthen security, quality assurance, and customer success teams. They will also focus on collaborating with research institutions and hiring new talent.

Looking ahead, the company wants WALL to handle more than just basic R&D efficiency. They are aiming for cross-functional optimization that covers design all the way through production engineering. The AI interpretation function will be adapted for specific industries so it can be applied in new areas like agricultural machinery and food manufacturing equipment. The goal is to make WALL useful across many parts of manufacturing and not just in traditional automotive or chemical sectors.

SUPWAT started in December 2019. In just a few years, it has gone from a startup idea to a platform used by large enterprise manufacturers. The new funding shows that investors see the value in what the company is doing. For the manufacturing industry, this is an example of how DX platforms can make a real difference. WALL is helping companies run experiments faster, make sense of complex data, and reduce wasted time.

This round and the roadmap for WALL make it clear that digital transformation in Japan’s manufacturing sector is moving forward. It is moving beyond pilots and small experiments and toward real, scalable platforms. SUPWAT is one of the companies leading that change.
