Message from Group CEO

You and simulations have the power to change the world.

Prometech Group is an industry-academia collaborative venture that strives for the research, development, and practical application of cutting-edge simulation technology. At the same time, we are a comprehensive solution provider that delivers "new value of simulation" to industry and society.

It is well known that simulation is widely used in advanced design of automobiles and aircrafts, and beautiful "computer graphics" in movies and games are in fact nothing but "optical simulation. And "AI," which has become a major trend in recent years, can be described as "simulation using a mathematical model that simulates the brain. All of these have in common the methodology of "solving mathematical equations with a computer. Simulation is an important fundamental technology that supports modern society with unlimited possibilities.

Since its founding in 2004, Prometech Group has focused on developing simulation technology, based on study at university, into CAE software used by industry around the world.

Prometech was also the first company in the world to successfully utilize GPUs in the CAE field, paving the way for users who cannot afford expensive large computers to take advantage of simulation. Today, Prometech Group continues to take on the challenge of bringing together the expertise of all group companies to make the power of simulation more widely available to society.
