About us

VIER combines communication and cognition. We support the intelligent processing of concerns.

Our technology makes the content of communication processes understandable. Speech analytics reveals the communication potential of agents.

We accompany work processes intelligently and provide support in solving tasks. That is empowerment on the job.

VIER analyses communication and automatically provides answers to routine questions. This leaves more time for complex tasks.

VIER combines a global communication platform, analytical expertise and know-how in process management and automation.

VIER offers its own communication platform for any kind of communication. It is stable, highly scalable and secure.

AI is influencing the world of work. It can support processing intelligently and helps to complete it successfully.

As a leading provider of call centre software, we know how to control and optimise processes for transaction processing.

VIER personally accompanies and supports companies comprehensively and sustainably on the path to the digitalisation of work.
