VIER Tech Stack

AI-powered contact center platform built on German cloud infrastructure

IT Services and IT Consulting Hannover, Niedersachsen 201–500 employees Founded 2021 Public Company

VIER operates a contact-center platform combining voice, chat, and AI agents across customer service and sales workflows. The stack reveals a modern AI-first architecture—Dify, Langfuse, Haystack, DSPy for LLM orchestration, plus Qdrant for vector search—paired with enterprise ITSM integration (ServiceNow, Salesforce, Dynamics 365). Active migration from Nomad to Kubernetes signals infrastructure consolidation toward cloud-native deployment, while the hiring surge in engineering (5 open roles) and a focus on scaling AI services and conversational AI indicate the company is shifting from traditional ACD/voicebot capabilities toward generative AI-driven agent assistance.
