VIER is a leading technology company from the DACH region specializing in innovative, AI-based communication and customer dialogue solutions. Founded in 2021 through the merger of five established companies, VIER combines over 30 years of contact center expertise with state-of-the-art artificial intelligence. The company employs around 230 people and is headquartered in Hanover. VIER's cloud-native platform orchestrates customer interactions end-to-end. The core portfolio includes the contact center software "VIER engage" for inbound and outbound telephony, as well as the "VIER AI Studio," which allows companies to create their own AI agents via a low-code editor. This is complemented by "VIER Copilot" for real-time action recommendations and "VIER Interaction Analytics" for the automatic analysis of customer conversations. A key differentiator of VIER is its uncompromising data sovereignty. All cloud solutions are operated in compliance with GDPR in certified data centers in Germany and Switzerland. The solutions also comply with the EU AI Act and the German Telecommunications Act (TKG). With certifications such as ISO 27001 and the Trusted Cloud label, VIER serves over 1,000 customers, particularly in highly regulated industries such as finance, insurance, and healthcare.

Customers rate VIER predominantly very positively: the simple handling of the ACD and contact center solutions, high operational stability, and very close, competent customer service with fast, solution-oriented support are particularly highlighted. The main strengths are considered to be the combination of a user-friendly interface for agents and admins, innovative AI and voicebot functions, and a reliable infrastructure; weaknesses mentioned are primarily a less intuitive statistical reporting system and occasionally perceived costs or layout clutter. VIER is particularly suitable for medium to large, demanding contact centers and service-oriented companies looking for omnichannel customer communication, AI-powered analysis, and a close, German-speaking provider with strong support.
