This case study details how a fintech company implemented Language IO to enhance its multilingual customer support operations. The objective was to provide seamless, high-quality support across three major European languages—French, German, and Italian—while maintaining brand voice and customer satisfaction. The integration of Language IO into existing systems like Zendesk allowed for instant translation, enabling agents to communicate effectively without interruption. The AI-driven model selection ensured that translations were fluent and contextually appropriate, even for complex terminology. The transition was executed with zero disruption to service, achieving 24/7 multilingual coverage and operational savings by consolidating local teams into a single global team. The case study also highlights significant metrics, including annual savings of $4 million and the capacity to handle up to 82 million words annually, demonstrating the scalability and efficiency of the solution. Overall, the implementation of Language IO exemplifies a successful strategy for managing global customer support in a rapidly growing fintech environment.
