AI-powered speech translation, interpretation, and captioning technology for live events and meetings.
Interprefy is a cloud-based translation and interpretation platform that delivers real-time multilingual audio translation, remote simultaneous interpretation (RSI), and live captioning for events of all sizes. Founded in 2014 in Zurich, Switzerland, the company has powered over 80,000 events across more than 150 countries, serving organizations ranging from Fortune 500 corporations to intergovernmental bodies including the United Nations and World Economic Forum. The platform combines AI-driven speech translation supporting 20+ languages with access to a curated global network of over 2,500 certified human interpreters, enabling a unique hybrid model where event organizers can blend automated and human interpretation based on content sensitivity, budget, and quality requirements. Interprefy's AI translation engine processes continuous spoken audio and delivers translated audio output with latency under 3 seconds, while its RSI module allows professional interpreters to work remotely from anywhere in the world, eliminating traditional on-site booth infrastructure costs that can exceed $10,000 per event. The platform integrates natively with Zoom, Microsoft Teams, Webex, and Hopin, and participants access translated audio or captions through any modern browser without downloading software. Interprefy holds ISO 27001 certification for information security management and operates on enterprise-grade cloud infrastructure with end-to-end encryption, meeting the stringent requirements of governmental and diplomatic proceedings. Real-time AI captioning generates multilingual subtitles for accessibility compliance under ADA, WCAG 2.1, and international standards, displayed on venue screens or personal devices. The company has seen over 300% growth in AI translation usage between 2023 and 2025, reflecting a broader industry shift toward automated multilingual communication solutions. With dedicated account management, custom SLAs, and API access for enterprise clients, Interprefy positions itself as the end-to-end multilingual event communication platform for organizations that require reliability, security, and flexibility at global scale.
