Agentic Systems Engineering.
Move fast. Sound decisions.

Grunetal's Ref is a collaboration platform for model based systems engineering, covering the full development cycle.

We designed Ref for the AI R&D age, where teams iterate fast with agentic execution, and virtual development throughput is massive.

Ref is built for emerging industries, to keep development coordinated as product and processes change. This also means that you can start right away, without installation.

  • No lock-in. Full escrow. You own the data, you own the service continuity.
  • Made with decades of experience.
  • European company.
  • Optimized end to end for minimal cost across governance, transfer, storage, and compute.

We listen.

You talk directly to the people building the product. We design for easy use and generic utility. We ship features in days, tested with tough edge cases. Our architecture is designed for fast extension.

Full trail.

From first idea to mature product.

Agentic automation is multiplying development throughput. More variants, more test runs, more data, faster. Teams that can't keep up with their own output lose track of what's current, what's been decided, and why.

Requirements shift, designs branch, campaigns produce results, variants compete. Ref keeps the full development trail intact.

V-model development cycle
Requirements & architecture

Start with what you have. Connect your repositories, upload model directories, experiment data. Write requirements and derive your initial architecture.

Development

Models, software, supplier inputs, design variants, organized in one place. Ref works with MBSE artifacts, SSP, FMI, to give you a few examples.

Test campaigns

Ref references exact inputs, code, and environment. Comparisons stay meaningful. Results are reproducible.

Evaluate and decide

Compare variant results against your criteria.

0%
Traceable

Every decision linked to its evidence. Every change varianted.

Tracked
Change impact

Know immediately what is affected when something changes. No surprises across teams.

Current
Always

Know which data is latest. Get notified when dependencies change. No more stale baselines.

AI agents working with structured project context

AI-native

AI agents that know your project.

Ref was designed for AI agents from the ground up. We would love to show you in person how we do this.

Open architecture supporting industry standards

Open by design

Bring your own tools. Keep your workflows.

Ref is built open. Keep using the tools and standards your teams already use, from MBSE toolchains and simulation environments to FMI/SSP and scenario testing on HPC. No lock-in. Your processes stay yours.

Our roots

Made by industry veterans. Hosted in Europe.

Ref grew out of decades of R&D collaboration consulting and project management, designing and managing global corporate platforms. We are a German company, working across Europe for best cost and compliance. Your data stays in your country, or wherever you want it to be.

We listen. We adapt. We deliver.

The teams who organize their development for agentic throughput set the pace in their industry. Free pilot. See where you stand.
