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, with less platform risk holding them back.

Let's talk See how it works

What we are

Not what embedded software usually looks like.

Your usual options, and why this is different

What you get: Full control over architecture and roadmap.

The catch: High upfront cost, a long path to working software, and open-ended maintenance obligations.

With ROSA: Same ownership, less investment, and maintenance costs distributed across all platform customers, not carried by you alone.

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 predictable costs regardless of what the platform brings up.

>95% reuse

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

Sound familiar?

The platform problems you shouldn't still be solving.

Almost every embedded team we talk to carries some version of these. ROSA is designed to address all of them. Your product stays yours.

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.

Maintenance FTE equivalent

–

Full-time engineers your maintenance load requires each year.

Annual maintenance cost

–

At fully loaded cost. Engineering capacity going to keeping the platform alive rather than building product.

Estimated saving with ROSA

–

Based on typical ROSA customer outcomes. The exact figure depends on your stack and migration path.

Rough estimates based on industry averages. Not a commitment. Talk to us for a number specific to your situation.
