Weijian Technology

Shanghai Weijian Technology Co., Ltd., operating under the brand name WEIBUILD, was established in June 2020 to address key challenges in the construction industry through automation. The company is headquartered in Baoshan, Shanghai, and focuses on the research, development, and production of intelligent construction robots. Its founder, Liang Yanxue, brought a decade of experience in industrial robot research and development from Japan's Fanuc, establishing himself as an authority in the field before starting the company. This deep expertise in robotics is a foundational element of WEIBUILD's strategic direction.

The firm has secured significant financial backing to fuel its growth and product development. It has raised a total of $15.7 million over two funding rounds. A notable Series A round on August 23, 2024, was led by Ruiyi Investment and Linear Venture, with participation from other investors including Sequoia Capital. This influx of capital is directed towards the research, production, and marketing of its robotic systems. The company has received recognition for its work, including being awarded as a "New Enterprise in the 30th Anniversary of the Construction of the Overseas Student Entrepreneurship Park" in June 2024.

WEIBUILD operates in the construction technology market, providing AI-driven robotic solutions to construction companies. Its business model centers on selling these advanced robotic systems that perform tasks traditionally done by manual labor, aiming to enhance safety, quality, and efficiency on job sites. The company serves major construction enterprises, including giants like China State Construction Engineering Corporation and Shanghai Construction Group. Its product line is divided into two main categories: the "Intelligent Wall Construction System" and the "Intelligent Reinforcement Processing System". The wall system includes plastering, spraying, and modeling robots, while the rebar system features machinery for intelligent processing and forming. The plastering robot, a flagship product, can operate autonomously to complete around 300 square meters of high-quality plastering per day, a 4-5 times increase in efficiency over manual methods. This system significantly reduces issues like hollowing, achieving a rate of just 0.7% to 1.2%. To complement its hardware, WEIBUILD develops its own simulation software based on BIM models, which automates path planning and corrects for discrepancies between the digital model and the actual construction site, thereby optimizing the robots' performance.
