About Us

FIEBIG – Your CX Transformation Partner

We see three major topics when optimizing the customer experience (CX) of companies: People | Processes | Technologies.

The technology factor has never been as decisive and characterized by rapid development as it is today – even if the company's development towards a value-enhancing CX for customer service, sales and marketing is always a holistic process that spans these three fields.

By using innovative technology, companies can drive their success in a targeted way.

For 50 years, FIEBIG has specialized in providing companies with expert advice on the latest customer service and call center technologies and supporting their introduction and operation.

As a vendor-neutral system house, we design holistic solutions that reach beyond individual products.

Customers & business basis

Our customers include numerous renowned companies from various verticals throughout Germany. Our business is based on trust which is built through respectful collaboration at eye level. You entrust us with your challenges and visions - together with you, we develop customized solutions.

In close dialog we develop the right concept for your CX transformation with the goal of process automation, optimization and employee relief.

This is where contact center technologies, artificial intelligence (AI) and interface integration come together.
