It is designed to fit in your wallet, front pocket, or behind your phone easily. PIECE is so small that it is only the size of a CREDIT CARD! That’s why we like to call it, “The Next Small Thing”

Of course! We have iPad users in mind

If you only want to carry your iPad on the go, before PIECE you would be unable to make phone calls. With PIECE we solve this problem! Download the app and your iPad can also turn into your smartphone!

When we designed PIECE, we only had one thing on our mind – creating the “next small thing” for user experience. We were challenged with designing a double Sim solution for a smart phone while keeping a VERY compact size. The process was amazing and our final product makes us proud! From technologies to research to batteries, designing PIECE has been a journey. We spent months choosing suitable materials for making a thin, lightweight product. With your help, we hope to bring PIECE to life in the very near future.

Riesgos y desafíos

We have worked extremely hard over the last months to deliver a product you will love and we can be proud of. As this is our second time launching a product on Kickstarter, issues should also be minimal.

The Main Challenges Ahead:


Creating PIECE requires engineering a complex system. To make sure we get this right, we have assembled an experienced team of engineers and designers. We have already built two generations of prototypes. Currently, we are producing the first batch to test with users.


Taking prototypes to mass production involves sophisticated logistics and relationships with suppliers. To minimize these risks, we have been negotiating with suppliers (including backup suppliers), testing component quality, and building a team that can execute on our promises. Our plans are nearly in place, and we require the resources to ensure we achieve this.
