The challenge was to provide a robust, real-time chat solution that could handle the high volume of messages and users during large-scale battles and events.

Prior to PubNub, Swiggy handled customer support inquiries primarily through agents in a call center and secondarily through customer support chat in their platform. As a result, even simpler requests—like a customer needing to cancel an order— were usually resolved through a phone call. For customers, this often led to resolution times of up to five minutes. And for support agents, significant manual work and time was spent on minor inquiries. With their previous phone support system, simple requests would turn into multiple questions that would lead to agents needing to navigate through multiple dashboard screens and customers sometimes needing to wait for agents due to limited availability. As Swiggy grew and regularly needed to handle up to 200,000 customer inquiries a day with a peak concurrency of 2,000 users, they turned their focus to adapting their support model to better scale. To accomplish this, they focused on building out their chatbot support.
