Customers Building the Next-Generation of Realtime Apps with PubNub


PubNub is reliable. It’s efficient. It’s fast. It’s everything we were looking for. In the EMS/911 space, efficiency is key because how quickly the first responders and public safety agencies respond determines life or death. PubNub has all of that.

From testing, to 1,500 rides a day today, to an estimated 15,000 rides a day in the coming months, we’re confident PubNub can handle that growth.

DevOps isn’t our core competency. I’d much rather work with a dedicated service like PubNub to fulfill a well-defined need, like quickly transmitting data between players, so our engineering team can focus on the hard problems that are unique to our business.
