Our philosophy - 360°agile - focuses on four aspects: Customer, Quality and Standards, Employees and Environment. We believe that every action has a purpose and a recipient, and our work should be organized in such a way as to meet the needs and requirements taking into account all four aspects as balance and cost-effectively as possible.

Our 360° agile approach finds its application in innovation - we creatively approach the improvement of solutions, business processes and technologies for our clients.


Cooperation. Transparency. Result oriented.
Together with our clients, we focus on what is most important to achieve the set goals and meet expectations. We believe that this is only possible with open and results-oriented communication.

Quality and standards

Professionalism. Competence. High qualifications.
Continuous education and training throughout the entire organization ensure and maintain quality at the highest level. In addition to proven methodologies, communication and social factors play an important role in the success of projects in cooperation with HN Experts.


Trust. Respect. Determination.
A coherent organizational culture and independence in making decisions are part of our activities. We transparently deal with contradictions, enable and constantly promote innovative approaches and thinking. Together, we strengthen our competences, and thus create the necessary basis for building (workplace) the world of tomorrow.


Modern. Sustainable. Remote.
Remote and hybrid work is firmly rooted in our philosophy and approach to work. We only travel where it makes sense and is absolutely necessary. Our goal is to reduce CO2 emissions as much as possible, and thus achieve climate neutrality.
