We are providing educational and competence development services as part of our consulting services. The competence development is guided by the insights from our fundamental research. However, we provide any kind of level of education from the very beginnings of practical data analysis up to the state of the art research level.

Revolutionary foundational research

OiCOS is the result of Viktor Winschel's research: a new foundation for the social sciences. The indispensable mathematical structure for economics, bio, social and cognitive sciences is reflexivity - first built in the mathematical approach of computer science. Reflexive means capable of self-description. Thus, self-similar structures at different levels and meta levels can be used to organise and manage complex systems. The reflexivity of computer science, first presented as Church's lambda calculus and the Turing machine, is needed for the analysis and synthesis of living systems. To be sure, computer science is not about computers but about the design of languages to describe algorithms which are procedures of information processing. This is reflexive since it is itself an information processing procedure, just as societies are defined in modern sociology as communication that produces communication. The same reflexive foundations now increasingly serve mathematics to reorganise itself, computer science and physics by the meta mathematics of category theory which is based on the organisational and process oriented principle of compositionality that allows for reflexivity.

The current prevailing mathematical foundations of economics are unsuited to the analysis and, above all, synthesis or compositionality and thus organisation of living systems. The shortcomings or reductionistic science or world view can not other then to cause environmental catastrophes, diseases, species extinction, plastic continents let alone authoritarian regimes over people.


In the corporate context, these are declarations of bankruptcy.

We use these insights to design and implement management systems that are suitable for living and complex systems such as energy or monetary and FinTech systems for companies with strategic interactions.
