In 2024, ExtendSim was acquired by ANDRITZ, Inc. - a globally leading supplier of plants, equipment, automation solutions and services to a variety of sectors.

The ExtendSim Team has been dedicated to bringing the art, science, and fun of simulation to the desktop, in a form digestible and accessible by everyone.

Over the last 3+ decades, ExtendSim has continued to innovate, establishing many other firsts in the simulation industry.
