4Rooks · ROSA Platform

Build the product.
Not the foundation.

ROSA gives embedded teams the tooling, code generation, and platform foundation to ship connected products faster than they thought possible.

Let's talk See how it works

At a glance

Not what embedded software usually looks like.

Faster to start, less expensive than building in-house, and a foundation that scales with your portfolio rather than against it.

3 days to PoC

First code running on your own hardware. No months-long onboarding, no department-wide commitment.

-75% costs

Compared to building it in-house. Fixed price, with the platform risk staying with us, not you.

>95% reuse

Across hardware variants. Each new product line costs less than the last to bring up.

The Problem

Does any of this sound familiar?

Most embedded teams spend the majority of their time maintaining the platform, not building the product. These are the patterns we see most often.

Maintenance is crowding out your roadmap

Your platform team spends most of its time keeping things running: patches, driver updates, regressions. New features wait. The backlog grows.

Every new variant means starting over

A new hardware target or product line sends your team back to square one. Nothing transfers cleanly. The cost multiplies with every variant.

Platform risk lands on your team

Certification issues, long-term support obligations, security gaps. All your problem. You built it, so you own whatever goes wrong.

The knowledge lives in two people's heads

Your platform depends on a handful of engineers who understand how it actually works. If they leave, you have a problem. If they're busy, everyone waits.

The Platform

Meet ROSA.

A complete embedded software foundation. You keep full ownership of your product. We handle everything underneath it.

ROSA Composer

One configuration. A complete SDK.

Define your hardware targets, system architecture, and module selection once. Composer generates your SDK, module interfaces, and build system — including only the protocol modules your product needs, from CAN and Matter to BLE and OTA.

ROSA Interconnect

Stable interfaces across changing hardware.

Interconnect abstracts the layer between your modules and the OS. Chipset swaps, variant additions, connectivity changes — the interface stays stable. Your application code doesn't move.

ROSA Atelier

From HIL to CI, included.

Hardware-in-the-loop testing, automated architecture validation at build time, AI integration, and built-in observability. A complete development workflow, not just a runtime.

Building your product was never easier.

Existing product

Start from an existing product

ROSA slides in as the hardware abstraction layer. Your application code stays in place.

Module library

Start from our module library

Select your base modules — CAN, BLE, GUI, speech, and more — and build up from there.

AI agent

Generate a starting point

Describe what you're building. An agent generates your architecture and module selection for review.
