About PlantStream

“Revolutionize Plant Design, Boost Creativity”​

PlantStream was established in 2020 as a joint venture between Arent Inc and Chiyoda Corporation. Since 2025, it has been operating as a subsidiary of Arent, developing and selling the 3D CAD software “PlantStream®.”  

The plant industry still has a number of design-related issues where there is room for improvement, such as human and environmental impact. PlantStream was launched with the aim to develop and provide next-generation 3D CAD to free engineers from labor-intensive work and creat a world where they can maximize their creativity. ​

Pioneering the Future of Plant Engineering

Plant engineering is an extremely complex process that demands vast amounts of data and advanced expertise. To achieve optimal outcomes within the constraints of cost and schedule, it is essential to ensure both safety and efficiency. However, the industry is currently facing significant challenges, including the declining number of experienced engineers and the increasing reliance on individual expertise and know-how.

At the same time, the environment surrounding the plant engineering industry is rapidly changing, driven by energy transition and the push toward carbon neutrality. In this new era, plant engineering must embrace digital technologies to enhance efficiency and enable data-driven decision-making at an advanced level.

At PlantStream, we are committed to addressing these challenges. Our solution facilitates the sharing and succession of knowledge, transforming engineering operations into more efficient and creative processes. We aim to create an environment where engineers can focus on innovation and bring new value to the industry.

Together, let’s build a sustainable future through the evolution of plant engineering.

Unleash human creativity with the right tools.​

While an efficient CAD, PlantStream goes well beyond this by revolutionizing design workflow with the potential to reinvent ideas themselves. Bringing out the best of human creativity and making the software to support it. This has been my mission since beginning a career as a programmer. PlantStream is making it a reality, enabling plant engineers all around the world to unleash their creative potential.
