Financial institutions are under pressure to modernize due to rising customer expectations, evolving threats, and growing data volumes. Over 60% of senior banking decision-makers admit that their slow digital transformation has resulted in missing out on winning new customers. To address this, leading banks and fintechs turn to Redis for speed, scalability, and intelligence. Mobile-first users demand real-time app experiences, while AI-driven customer services are becoming table stakes. Financial institutions use Redis as a session store or cache alongside existing systems to improve performance and scalability without rearchitecting. This helps with mobile banking, fraud detection, and customer service by providing instant access to data, detecting fraud instantly, and powering AI-driven innovations. With Redis's sub-millisecond latency, decisions are made instantly, saving millions in potential losses each year. The technology also enables semantic caching, improving response accuracy and performance, particularly for AI-powered applications like chatbots. By leveraging Redis, financial institutions can deliver real-time experiences, fight fraud instantly, and scale AI-driven innovations without rearchitecting from scratch.
