White Box


Custom White Box Solutions

Do you want to launch your branded telecom device with tailored features without investing in the design from scratch? We are here to assist you. Our team builds turn-key white box solutions, utilising hardware directly from manufacturers and creating fully customised software to address all your needs.

The white box approach enables you to bypass ground-up development while providing the flexibility to escape vendor lock-in through disaggregation. Therefore, you can swap out the white box hardware without developing an entirely new software system, making it a cost-effective solution.

We're proud to be members of prpl Foundation!
