Designed to last!

Why do we replace our smartphones so often? The answer is poor and unsustainable design. We are determined to change that – design and manufacture a device that maximizes the lifecycle of the electronics. The first step is to make sure that you can easily upgrade your device to meet your needs or fix a faulty module or component yourself.

It really is that simple!

The PuzzlePhone business model can be replicated anywhere under the PuzzlePhone Compatible license. We advocate reshoring of manufacturing and rest of the hardware value chain. By creating closed loops within circular economy business models we are not only creating more work locally but also maximising the resource and energy value throughout the device lifecycle.
