Esper specializes in providing management tools for Android and iOS devices, offering solutions for managing edge, dedicated, and fully managed devices. The company has expertise in Android OS behavior and has developed its own Android distribution called Foundation for dedicated devices. A common challenge for businesses using device management (MDM) systems is the need to switch infrastructures, which typically requires a factory reset of all devices. Esper can facilitate a seamless transition from incumbent MDM systems to its own by leveraging access to OS source code and utilizing over-the-air (OTA) updates. This approach is particularly beneficial for businesses that have outgrown their existing MDM solutions and need more flexibility and scalability. The process involves close cooperation with original device manufacturers (ODMs) to obtain the necessary source code and OTA services, allowing Esper to update and manage devices efficiently. The transition is supported by Esper's Blueprints, enabling precise device configuration without manual intervention. However, the process requires careful planning and execution, especially when dealing with heterogeneous OS builds or limited Internet bandwidth during updates. Ultimately, Esper provides a unified platform for managing mixed fleets of devices, thereby enhancing business operations and growth potential.
