Japan-based construction technology startup ONESTRUCTION has raised a total of ¥910 million in a new funding round to accelerate the development of its AI-powered construction and building information modeling (BIM) solutions.
The funding round included both equity and debt financing. Equity investors included Mitsui Sumitomo Insurance Capital, Regional, People and Future Co., Ltd., Chugin Capital Partners, and Albacross Co., Ltd., while debt financing was provided by Japan Finance Corporation, San-in Godo Bank, and Tottori Bank.
Founded in 2020, ONESTRUCTION develops digital construction technologies focused on openBIM systems and artificial intelligence applications for the architecture, engineering, and construction industries. The company aims to accelerate digital transformation and improve operational efficiency across the construction sector.
The newly raised capital will be used to expand development of the company’s core platforms, including OpenAEC, Ishigaki, and Contex. OpenAEC is designed as a BIM data quality control platform, while Ishigaki focuses on AI models specialized for construction-related tasks. Contex, the company’s upcoming platform, is intended to help structure and utilize construction data more effectively through AI-powered systems.
ONESTRUCTION also plans to strengthen its engineering and business development teams, expand research and development activities, pursue overseas market expansion, and build strategic partnerships with international companies.
The funding reflects growing interest in construction technology and AI-driven infrastructure solutions as the industry increasingly adopts digital tools to improve project management, data handling, and operational productivity.
With construction firms worldwide facing labor shortages, rising costs, and increasing project complexity, startups like ONESTRUCTION are positioning themselves at the intersection of AI, automation, and digital infrastructure modernization.
