About Us

OpenBack was founded on the belief that mobile notifications have become the primary interface for mobile devices, driving what users do every day.

Frustrated with how clumsy and clunky push notifications were everywhere, the team knew that a better way for mobile apps to do notifications would emerge and that they were in a great position to lead that evolution of notifications to become truly user centric.

The team set about rebuilding how things should work, always from the user’s point of view, unconstrained by current technology norms and mass acceptance that traditional push notifications are up for the task at hand.

One of OpenBack’s core observations, and hence a core part of the patent and IP portfolio, is that each mobile app, beside each user, should manage and control the delivery and ongoing management of notifications in a personalised, yet scalable way.

Every business and hence almost every mobile app wants to talk to their customer as often as possible, but without upsetting that user, which could result in an notifications being blocked forever, or worse the mobile app being uninstalled.  OpenBack helps companies manage that balance effectively.

OpenBack is trusted by some of the world’s largest and most innovative companies to deliver amazing notifications experiences to their customers and users.
