The term ecosystem (known primarily from the field of ecology) describes a complex system whose organisms interact with and support each other. This term has also become increasingly important in both economics and science, e.g. with Deloitte and the concept of business ecosystems. In these contexts, it is mainly used in connection with platforms. Now, we would like to introduce this term into the discourse on sustainable development and are advocating a cooperative, ecosystem-oriented, instead of market-oriented, society. As strategic platform facilitators, we are helping to consolidate the multitude of offerings into an interactive solution portfolio.
