What we offer


Mainly in the field of EU and state funds and grant schemes, ESG, sustainability, innovation and project management.


We plan, implement and support your project as our own, we strive for business relations relying on long term cooperation and mutual trust.


We pursue a can-do attitude – if there is a will, there is a way. We know, that things may change – do not worry, we will manage.

As an independent group of consultants, we trust that DEVELOPMENT and SUSTAINABILITY are mutually supporting notions.

Our international and national government and corporate experience shows that development and improved sustainability may be easier to achieve through INNOVATION.

The importance of sustainability is not a question any more – neither for decision makers, nor for individuals. We are to help you comply with green criteria in a way that not hinders, but on the contrary, supports the development of your organisation.
