Tailor-made software



We are just like you. We believe in simple yet important values.


Your business goals and needs are unique. They require deep analysis and a tailor-made solution.


Software should be simple and useful. 20% of functionality often fulfills 80% of your needs.


To accomplish high quality services, a high level of expertise and quality processes are needed.


Our mutual relationship, trust and ability to communicate are the most important factors affecting project outcomes.


We like to work where advanced knowledge is required. Where common content management systems reach their limits.

Thanks to company clarz we implemented several successful projects. Meetings with representatives of the company are executed in the spirit of proficiency and friendly, inspirative atmosphere at the same time. Our mutual cooperation brings high added value to both sides.
