Companion

Why does your AI prototype have no users and no value?

You've taken your first steps with agentic coding and noticed the gap: a prototype is up in hours – software your business relies on every day is a different thing. The Companion gives you the framework to get there – on your own infrastructure.

Why the Companion

Where agentic coding hits its limits

The tenth feature breaks the first

Without architectural guardrails, every agent run builds a little bit around the existing code. Eventually nobody understands the whole any more – the agents included.

With the Companion

We put the guardrails in before that happens – and keep them honest in your reviews.

Agents on your own machine are hard to control

An agent with access to your file system, your SSH keys and your credentials is a risk that grows with every run.

With the Companion

We move the work into isolated, self-hosted environments – reproducible and ready in minutes.

A lot sits between “works on my machine” and “runs in production”

Deployment, access management, backups, monitoring, sign-off by the people who will use it – all the steps a prototype skips.

With the Companion

We get your solution into a test and a production environment – and show you how to do it yourself next time.

Models change faster than your software lives

Build your application around one specific model and you have built your next lock-in.

With the Companion

We develop LLM-agnostically: switching models is a configuration change on your side, not a rewrite.

An example

An ERP that can do everything – but does nothing.

By now you've used AI agents to build an ERP prototype in a matter of days – one that knows your order structure and mirrors your calculations, closer to your processes than any off-the-shelf product.

But then comes the last, decisive stretch: multi-user operation, permissions, a server, backups and a safe way to ship updates are all missing. Which is why your ERP still runs on one machine instead of in your team's daily work.

That last stretch is the one the Companion walks with you.

Typical first building blocks

  • Quoting and order entry that reflects your calculation – not a standard product's
  • Time tracking and project hours, tied directly to your order structure
  • Interfaces to accounting, inventory and your existing databases
  • Reports you adjust yourself instead of ordering them from a vendor

From prototype to business software

Four steps – from your local setup to your own software.

01

📦Migrate

We migrate your local setup into a self-hosted, cloud-native development environment – standardising how you develop while sandboxing it, so local files and access stay isolated.

02

🤝Onboarding

We set up workspaces together, build the first features and ship them to a test environment for sign-off. And we talk through your vision together.

03

🏗️Modernize & Build

We put guardrails in place for LLMs so the resulting software is built to last: architecture, security and user experience. Throughout, development stays LLM-agnostic – no vendor lock-in.

04

📈Scale

We scale development with more stakeholders on your side, put the features into real use and support rollout and maintenance of the software.

Where it runs

Your software, your infrastructure, your rules.

The Companion runs self-hosted: on your own hardware or with a European cloud provider of your choice. There is no layer you don't have access to.

You & your AI agents Agents AI Gateway Secure environments Standardized, self-hosted development environments. AI agents Offload tasks to governed agents on your infrastructure. Governance Observe and control AI usage – compliant. Your infrastructure Self-hosted and cloud-provider agnostic.
