“Since deploying this support chatbot built with PubNub, Swiggy has been able to automate up to 70% of all customer support tickets. Because of this, their time to resolution has also decreased dramatically, from an average of around five minutes pre-automation to just 30 to 40 seconds now.”

“We've delivered billions of messages through PubNub—that is something that we've been very proud of. Being able to have that reliability allows us to focus on building a great user experience without having to scale every single part of our infrastructure.”

vFairs has saved 75% in dev time by moving from their in-house chat to PubNub. “With the growth we’ve seen in the past ten months, it would have been a huge problem and time issue to have to scale up our chat manually. Having PubNub means we have one less thing to worry about, we’ve never questioned if it will work and scale with us as we grow.”
