4Rooks provides the scalable foundation for connected products, enabling teams to manage growing software complexity while retaining full ownership and control of their devices.

ROSA is 4Rooks’ production-ready firmware foundation for connected Zephyr and Linux devices, designed to integrate into existing architectures and support modern technologies such as Matter, KNX IoT, Thread, and Wi-Fi.

We handle recurring system-level concerns like security, updates, observability, and hardware portability, including requirements driven by regulations such as the EU Cyber Resilience Act, so teams can focus on product-specific behaviour.

Our goal is to make building and evolving embedded devices significantly simpler and more predictable.
