PuzzlePhone Compatible empowers innovation

For manufacturers

Grow your customer pool. Wouldn’t it be nice to have a ready-­to-­burn, pre­-compiled OS that allows you to develop high­-quality devices for the masses, as well as on­-demand, tailor-­made solutions for niche sectors? Save time and money in developing your ideas.

For developers

A standard platform ensures on-­time upgrades, simplifying and reducing the IT workload for manufacturers and application developers. One single firmware compilation for every PuzzlePhone Compatible device means faster response and a better user experience.

For the end user

PuzzlePhone is easy to upgrade, easy to customize, and easy to repair. No more changing phones because of broken displays, outdated software, or an old battery – change one module only. Reliable auditing of the code and community support mean better debugging and safeguards against malware.

Made in Europe

PuzzlePhone is designed, engineered, manufactured, and assembled in Europe. Together with our partners in Finland, UK and Germany we are building the new era of mobile industry: sustainable mobile product that respects security and privacy.

Our R&D all-star partners

And although PuzzlePhone is, at the moment, made in Europe, we’re most proud of the fact that our full business ecosystem is completely replicable elsewhere making it a truly local system.
