About Us

The Stacked Learning team is composed of experts from AJ Stack Solutions who have over 400+ years of combined experience in the rotating equipment industry.


AJ Stack Solutions have been in the equipment and rotating machinery industry for over 40 years with 400+ years of combined field experience, where aside from offering Engineering, Asset Management,  Field Services, and more it dedicates itself to operations training in a physical workshop via immersive learning and interactive environments. Taking the learnings from physical workshops we have created Stacked Learning.

Stacked Learning has been developed to provide an immersive experience to the user while learning technical disciplines, with transferrable hands-on experiences, but in the comfort of your own home or office by implanting the technical content into a virtual environment within an online learning management system.

We have all experienced sitting in a classroom while a lecturer presents a Powerpoint presentation on some technical knowledge while battling to stay awake. That’s why, at Stacked Learning, we have developed an immersive experience to upgrade the user by learning highly technical content and transferable skills while enjoying it in the process.

Stacked Learning is excited for you to come on this unique opportunity with us to bring users across the world to experience places they have never been before and experience training that has never been done before.
