The main idea behind the product was an early version of BPEL with its own business process engine, all written originally in C++. The company had a component toolkit and a graphical business workflow builder. The company supplied a variety of different component packs that could be integrated into the workflow as actions. The builder produced a deployable artifact that was deployed to the server running the business process engine.
