About us


Holisticon’s experts are not simply identical robots with a standard solution for every problem. There are no workshops in which you can learn how work is carried out at Holisticon. Everyone is an individual, and that’s a good thing. Nevertheless we pursue the same objectives: high-quality software, successful projects, constructive conflict, creative chaos, and self-organization.
