We Turn IoT Firmware
into Scalable Technology.
4Rooks enables companies to build and maintain connected devices with reusable firmware modules — faster, easier, and built to last.
A mouse and an elephant share 90% of their genes.
In fact ALL mammals share 80-90% of their genome. One could say that nature created a universal operating system for what makes a mammal.
In spite of how vastly different the elephant and the mouse seem on the outside, their genetic code overlap is astonishing.
Three fridges from any maker are almost identical in basic functionality.
They all rely on the same fundamental building blocks—connectivity stacks, temperature-sensor handling, compressor and fan control loops, diagnostics, power-management routines, OTA update logic, and basic security layers.
Yet they share 0% code...
That seems extremely inefficient and makes no sense.
Think about it:
"Shouldn’t 90% overlap in functions
mean 90% overlap in code?"
At 4Rooks, we examined this simple question and came to an equally simple conclusion:
Yes, it should.
Introducing the solution:
ROSA
(Reusable Operating System Abstraction)
ROSA is a composable firmware framework made up of standardized components that can be combined to implement shared functionality across IoT devices.

ROSA lets your teams start 90% DONE — on day one.
Instead of rewriting connectivity stacks, Matter integration, telemetry, diagnostics, FOTA or power management for every new device, ROSA provides a reusable foundation built from standardized, interoperable components.
