We solve big problems in the EPC industry.

PlantStream is a joint venture between Chiyoda Corporation and Arent Inc. The EPC industry continues to face serious design challenges, such as its human and environmental burden, which have yet to be solved. We started PlantStream in order to share our solution to these industry-wide challenges by developing and providing autonomous CAD.

Reimagine conventional approaches
and environments.

One of the challenges faced in the field of plant spatial design is the sheer magnitude of tasks. While I, myself, have worked in plant engineering for 16 years in the piping design division, it was difficult to find a balance with my personal life. The fundamental reason for this was analog-centric inefficient design techniques, which haven’t changed for decades. Our mission is to overcome this work environment that has gone unchanged for ages. By replacing automatable manual work with software, engineers can engage in project delivery work without straining themselves and instead pour their energy into creative areas.

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.
