DATA IMPACT JOINT STOCK COMPANY (Headquarters: Vietnam, Representative: Dang Quang Duy, hereinafter "Data Impact"), a group company of Headwaters Inc. (Headquarters: Shinjuku-ku, Tokyo, Representative Director: Yosuke Shinoda, hereinafter "Headwaters"), which operates an AI platform business, has won the Grand Prize in the corporate division at the "Microsoft Agent Hackathon powered by Tokyo Electron Device" held on June 18, 2026. A total of 240 teams participated in this hackathon from across the country, and Data Impact advanced to the final screening and won the Grand Prize in the corporate division. The solution that received this award focused on the challenges in semiconductor factories, where highly advanced predictive maintenance is particularly required within the manufacturing industry. In semiconductor factories, the stoppage of a single piece of equipment can lead to losses of tens of thousands to hundreds of thousands of dollars per minute, making the prevention of sudden failures through predictive maintenance a critical management issue. In recent years, there has been a shift from conventional threshold monitoring, which detects anomalies when a certain standard value is exceeded, to AI-driven predictive maintenance, increasing the demand for advanced maintenance through data and AI. Against this backdrop, the AI agent-based predictive maintenance solution "Etsunami Agent" developed by Data Impact presented a practical approach to industrial needs, leading to this award. This solution enables predictive maintenance by utilizing a data infrastructure on Microsoft Azure and an analysis environment by Databricks, with an AI agent continuously interpreting and making judgments on the data.
