Why automate your customer service?

More time for the essentials in your customer service

Customer service teams in Germany receive 25 million inquiries every day. Via email, social media, letter & fax, WhatsApp, chat, and phone. This workload requires a cross-channel platform for intelligent customer communication that resolves customer concerns in a timely and case-closing manner. At the same time, service teams are free from recurring routine tasks, which allows them to focus on more complex matters.

These are the three essential factors for successful customer service:


Unified Desktop: Provide continuity and connectivity across all contact channels on one interface.

Artificial Intelligence

Our AI analyzes and recognizes the topic and provides suitable answer suggestions.

Workflow Automation

In our workflow engine, you can easily model all your business processes individually.

How accurately do you want to answer your customers?

Unique AI for customer service - Made in Germany


In our response management solution ReplyOne, a unique categorization algorithm is used. It was developed at the German Research Center for Artificial Intelligence (DFKI). 

Highly developed, vector-based AI algorithms and statistical processes identify and solve your customer service challenges with precision. Service processes are automated - for happy customers and satisfied employees.

On the occasion of the company's 20th anniversary, DFKI evaluated our customer service software. Especially the small amount of learning data that is needed as well as the high precision of topic detection make our categorization unique – a hallmark for first-class AI. Of course, the entire process is GDPR-compliant.
