4Rooks · ROSA

The best firmware team is your own.

ROSA is there to back it: managed Zephyr & Linux, scalable firmware modules, hardware-in-the-loop testing, CRA readiness, management transparency.

Let's talk How an engagement starts

2 days

From "where do we stand?" to your team's prioritized plan: CRA readiness, software quality, or more product per engineer.

up to 75%

Less of your team's time on Zephyr & Linux maintenance, ROSA manages it. Budget and people go to product instead.

>95%

Of your team's firmware modules carry over to the next hardware variant. Nobody starts from square one.

Who gets what

Not a replacement for your organisation. Equipment for it.

Every role that has to answer for the product gets something concrete on day one.

ROSA Atelier

You always know where your products stand.

Atelier is the web interface over your whole firmware estate: status and forecasts for management, policies for architects, the daily work for engineers. Same records, no separate reporting.

ROSA Atelier, portfolio status with forecasts

Every project: progress, forecast, test posture, upcoming milestone, derived from the records, not from Friday reports.

ROSA Atelier, architecture editor

Architecture set within company policies: approved hardware, module allow-list, patterns. Deviations are explicit, never silent.

What we solve

Three problems. One foundation.

Each of these stands on its own, and they compound when the same foundation carries all three.

CRA reporting obligations apply from 11 September 2026.

If you can't produce a current SBOM for every product in the field, the clock is already against you.

However you build

In-house, software house, or white-label: ROSA helps either way.

We don't ask you to change how you source your firmware. Whichever way you build, ROSA adds what's usually missing: transparency, speed, and evidence you own.

What ROSA gets you: Your engineers stop rebuilding the undifferentiated layer. Board support, connectivity, OTA and security patches are maintained for you, with the cost shared across all platform customers. The quality stack and Atelier add the visibility home-grown setups never had time to build.

Your architecture, your IP, your roadmap, with capacity back on product.
