The Challenge: A high-volume business like DoorDash needs to make thousands of daily outbound calls to its merchant partners to confirm orders and availability. Handling this manually is slow, expensive, and prone to errors, which can delay deliveries and impact the customer experience. The Solution: The challenge was met by implementing an AI-powered voice agent to automate outbound calls to merchants. This system was designed to handle a massive scale of concurrent calls, resolving routine operational tasks without human intervention, thereby improving the merchant experience. The Impact: This AI application transformed the company's operational efficiency. It successfully automated over 35,000 calls daily and achieved a 94% success rate within the first six weeks of deployment. Furthermore, it cut the average call handling time by nearly half (49%), speeding up the entire delivery lifecycle.
