What’s the #1 risk for an integration or data migration project?

The mutual understanding between IT and Business is lacking

Why RMS Core Mapper really matters

In integration and data migration projects, the biggest risk isn’t technology — it’s misunderstanding.

RMS Core Mapper allows domain experts and application specialists to define mappings and data flows together — without writing code.

The result is not screenshots or spreadsheets, but versioned artefacts:

These artefacts can be committed to your repository and used by developers without requiring a Mapper license.

A small number of people create clarity that many others rely on.

Why developers don’t need a license

Because developers shouldn’t need another tool just to understand what to build.

Authors create

  • Mappings between source and destination formats
  • Markdown documentation
  • Mermaid diagrams for flows and dependencies

Everyone else consumes

  • Review artefacts in pull requests
  • Use outputs in implementation and testing
  • Reuse knowledge across teams and projects

You license authorship — not understanding.

Pricing designed for collaboration

RMS Core Mapper is licensed per author — the people who create mappings. The artefacts they produce can be shared with developers, architects and support teams without requiring additional licenses.

We are currently onboarding our first customers and working closely with early adopters. Typical author licenses are in the range of a few thousand USD per year, depending on the number of authors, project scope and collaboration model.

How licensing works

Authors

Domain experts, application specialists and architects who create mappings, diagrams and documentation.

Consumers

Developers and other stakeholders who read the artefacts in Git, review diagrams and implement the integration.

No license required.

Who RMS Core Mapper is for

RMS Core Mapper is designed for teams working with complex integrations and data migrations. It works particularly well when domain experts understand the business logic, while developers need clear documentation before implementation.

Typical users include application specialists, integration architects, domain experts and development teams working with APIs or message formats.

Let domain experts design the mapping — and let developers implement it with clarity.

Frequently asked questions

Why is RMS Core Mapper licensed per author?

Because the value comes from the artefacts created by a small number of experts. Those artefacts can then be shared with developers and other stakeholders without requiring additional licenses.

Do developers need a license?

No. Developers can use the generated artefacts, documentation and diagrams without requiring an RMS Core Mapper license. Licenses are only needed for people who create and maintain mappings.

Can we start with a small setup?

Absolutely. Many teams start with one or two authors and expand as more integration work is planned. We’re happy to discuss a setup that fits your project.

Early adopter programme

If you're planning an integration or data migration project, we'd love to work closely with you and shape the product together. Early adopters get direct access to the founders, tailored onboarding and influence over the roadmap.
