Offering · Efficiency

Same team.
Several times the portfolio.

Your embedded engineers are scarce, expensive, and mostly busy with work that doesn't differentiate your product: board bring-up, connectivity stacks, update mechanisms, dependency patches. ROSA carries that share of the work, so your team's capacity goes back to product.

Let's talk Put a number on it

The mechanism

You write what makes the product yours. ROSA carries the rest.

The rest is nearly identical across every product you build. What you write is specific to yours. That's the entire point.

Your team builds

  • —Application logic and domain knowledge
  • —Product-specific behaviour and business rules
  • —Hardware target configuration
  • —Your IP, untouched and fully owned

ROSA carries, maintained by us

  • —Board support & Zephyr integration: running application in hours
  • —Connectivity: Matter, Thread, KNX IoT, BLE Mesh, Wi-Fi
  • —OTA updates: MCUboot, A/B partitioning, rollback
  • —Dependency & security management: we keep up so you don't
  • —End-of-line testing & provisioning: factory-ready from the start

The economics

Every product after the first costs less to build.

Reuse is the compounding asset: the modules your products share carry over, so each new product or variant starts most of the way done.

>95%

of your firmware modules carry over across hardware variants. Changes stay contained, variants don't diverge.

up to 75%

lower cost than in-house platform work. The tools' maintenance is carried by all their users, not by you alone.

Maintenance FTE equivalent

–

Full-time engineers your maintenance load requires each year.

Annual maintenance cost

–

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

Estimated saving with ROSA

–

Per the 4Rooks ROI model: benchmarks, not guarantees. The exact figure depends on your stack and migration path.

Rough estimates based on industry averages: benchmarks, not guarantees. Let's talk for a number specific to your situation, or see how an engagement starts.

Adoption

Two entry points. Same destination.

New product, from scratch

Clone the devcontainer, target your hardware, and build something real from day one. ROSA generates the firmware system from your product model, as readable code in your repos; your team adds the application logic. What prototypes on dev hardware ships to production without a rewrite.

Existing codebase, from where you are

Pick the product or variant where the pain is highest and migrate that one. The rest stays untouched. ROSA wraps existing code rather than replacing it, so domain knowledge stays in the codebase. Migration is a direction, not a big-bang project.

Either way: the second product costs less than the first.
