At Preventai, weve built one of Europes first Video Language Models. On our platform, Antrino, you can take any camera stream and make it actually understand what it sees. Describe what you want to detect in natural language – choose from pre-built behaviors like theft detection, crowd counting, or PPE monitoring. Or jump into Free Roam and prompt custom scenarios: "alert when someone leaves a bag unattended" or "count defective products on the assembly line." No extra hardware needed. Just your existing cameras – that can suddenly talk, listen, and understand. Built from university research at Lund University, now deployed across retail, security, and industrial environments in Sweden, the US, and the UK. Turning surveillance into actionable intelligence.

Legal disputes are a disruptive element in the economy – often causing financial and even emotional stress for the parties involved. Despite the urgency of the problem it is rare to see a structured analysis of the risks and values involved. Eperoto provides a powerful yet easy to use software tool to produce risk-value assessments of legal disputes. We want to ensure that our users can make rational and informed decisions when handling the uncertainties of their disputes – be it a case in local court or international arbitration.
