The company offers a suite of proprietary software products including Lightning BIM, an advanced Building Information Modeling (BIM) platform that facilitates automated and optimal rebar layout, designed to integrate with Autodesk Revit and tailored to the architecture and structural sectors; PlantStream, a computer-aided design platform geared towards plant industry applications; and additional SaaS products infused with AI to transform operational know-how into accessible tools. Arent also provides comprehensive consulting services focused on driving DX and operational efficiency through automation, AI, and BIM integration aligned with on-site construction operations. The company's operations are structured into DX Business, focusing on consulting, proof-of-concept, and digital business co-creation, and Product Business, which centers on SaaS product development and external sales. Founded in 2012 and headquartered in Tokyo, Japan, Arent targets construction companies, plant engineering firms, and businesses seeking digital transformation in these industries. Recent strategic developments include its October 2025 acquisition of a 56.9% stake in Kensetsu.WEB, Inc., aimed at expanding its SaaS product lineup and technological capabilities, with plans to make Kensetsu.WEB a wholly owned subsidiary. Arent also formed a business partnership with Kyoei Sangyo in late 2025 to jointly promote AI use in construction operations. Its ongoing focus is integrating AI, BIM, and automation to democratize tacit knowledge and enable new business creation through digital transformation in the construction sector. The company operates domestically in Japan and has recently expanded operations internationally with subsidiaries in the United States and Spain.
