Start with a single module

Whether you have a device that needs software or an early product idea, we can discuss the next step. We review your materials and project stage to agree on scope, interfaces and deliverables.

  1. 01

    Agree on requirements and acceptance criteria

    Review features, existing materials and interfaces, and agree on what each stage needs to demonstrate.

  2. 02

    Development and integration testing

    Test prototypes, device connections or business workflows as appropriate, and record issues for review.

  3. 03

    Review and handover

    Review the test results and agreed deliverables. Hardware projects can then proceed to pilot and volume production.

Design for production, refine through pilot runs

Our team has experience developing mobile phones, from circuit boards and mechanical design to finished devices. We assess sourcing and manufacturing processes during design and use pilot test results to refine the product.
