Our brands

We are proud of our diverse corporate heritage

Before Acoem was established, we were individual data, engineering and science-driven businesses that shared common values and goals — to empower our customers to make more informed decisions for the environment and for their machinery. 

Coming together to form Acoem in 2011— and continually evolving since then to welcome other like-minded organisations into our fold — is the source of our strength. Learning from each other gives us the opportunity to constantly expand our knowledge base, to diversify our thinking, to cross-pollinate our technology and to offer our customers a more holistic view of balancing progress with preservation. 

Our 12 legacy brands developed reputations for excellence in their respective fields, trusted by governments, industry and academia around the world. We are proud of the advances made individually and as a united group.
