Case Study: NumberAI achieves seamless, reliable AI-powered customer conversations with PubNub

How PubNub powers their conversational AI-integrated experience

NumberAI is a realtime conversation platform that brings AI-powered phone and text communication to Main Street businesses, automating common tasks and rescuing missed callers. The company needed mission-critical, low-latency messaging that could scale unpredictably, meet strict telco reliability requirements, and let the team prototype and deploy quickly without building costly infrastructure.

PubNub provided the realtime messaging backbone and 70+ SDKs, enabling rapid testing, prototyping, and deployment while freeing NumberAI to focus on product logic. The result is a seamless, reliable chat experience between customers and the chatbot—faster time to market, scalable delivery that satisfies telecom partners, and fewer engineering resources spent on building and maintaining realtime infrastructure.
