About Apparatus GS

Apparatus GS is a Plexus company based in London, Ontario, Canada. We are an industry leader in building complex, custom web-based database applications to support professional learning and development and everyday business operations. Our global partner network allows us to localize and rapidly deploy and support solutions on an international and multilingual basis.

Our development process is driven by the Plexus Learning Model and begins by working closely with your team to identify underlying business processes and overarching business goals. This allows us to take a wider view of the problem, and to identify opportunities for improvement and efficiencies that often go far beyond the specific initial request.

We pride ourselves on maintaining long-term customer relationships and growing and evolving the solution as business needs change. Our work with the industry standard writing teams, subject matter experts, TPABs, TPs, OPMT, Auditors, Accreditation Bodies, OEMs, and Primes provides us a unique understanding of process flows throughout the entire supply chain, which is built into our solutions.
