We develop scalable conversational AI for the enterprise and mid-enterprise segment. ONLIM supports companies in intelligently automating their communication across chatbots and voice assistants — across all channels and under the highest requirements for quality, security, and control. Our knowledge-graph-based AI platform makes complex enterprise knowledge accessible in natural language — via phone, chat, web, messenger, and email. GDPR-compliant, hosted in the EU, and seamlessly integrable into existing system landscapes.

Founded in Austria in 2015, ONLIM has been developing AI-based chatbots and voice assistants for more than ten years for companies that require reliable, scalable, and secure automation.
Early on, we combined knowledge graphs with modern AI technologies, thereby laying the technological foundation for a conversational AI platform specifically designed for the requirements of mid-sized and growing enterprise companies.
