Who we are: Kontrollfeld, an AI agency from Berlin
AI-generated, human-reviewed
Kontrollfeld is an AI agency from Berlin. We build AI and automation systems for companies and institutions — and we hand them over as running, maintained software, not as a slide deck. This piece summarises who we are, what we build, and how we work.
What we build
We specialise in AI integrations and systems architecture, with a focus on systems that move past the prototype and into operation:
- RAG systems (retrieval-augmented generation): your internal knowledge becomes queryable — with an evaluation harness and an operating model, not just a demo.
- MCP servers: connecting tools and data sources to language models cleanly and under control.
- Single sign-on with Keycloak: identity and access solved centrally and to standard.
- WebRTC architectures: real-time audio and video where latency and reliability matter.
- Software and systems architecture: the foundation that lets the building blocks above carry weight in production.
On top of that, we bring years of web-platform experience, Drupal among them. As an AI agency from Berlin, we connect the two worlds: AI systems embedded into existing platforms and processes, rather than bolted on beside them. We don’t sell a feature list; we deliver a result that holds up in your organisation’s day-to-day.
What ties these building blocks together is less the individual model than the question of how it fits reliably into an existing context: where the data lives, who may access what, how quality is measured, and how the system keeps running day to day. Those questions decide whether an idea becomes an operation.
How we work
Our guiding principle is simple: we operate the systems we sell. This website is the proof — it runs on the same Git-based pipeline we use for client projects. Every editorial decision is a commit; every line of the pipeline is code-reviewed. Four principles follow from that:
- Productive, not a demo. We deliver systems that live on after the prototype — with operations, monitoring, and documentation. A proof of concept nobody runs is not a result to us.
- Self-hosted by default. Data and models stay where you want them. That is GDPR-friendly and avoids lock-in to third-party clouds.
- Auditability over magic. Decision logs (ADRs), reviewable pipelines, and visible provenance of AI-generated content are part of what we ship, not an extra.
- Straight to the engineers. There is no sales layer between you and the implementation.
We name trade-offs rather than smoothing them over. Whatever technology we recommend follows the use case — not a hyperscaler stack we happen to be tied to.
How a project starts with us
It starts with a concrete problem, not a tool. First we clarify what should measurably improve — answer quality, turnaround time, operating effort — and derive the architecture from that. We record the key decisions as ADRs, so it stays clear later why a solution looks the way it does.
Then comes a narrow but real slice: a working path rather than a presentation, instrumented with evaluation from the start so quality is demonstrable. Only once that holds do we build out the breadth and set up operations — monitoring, deployment, documentation. That keeps the path from prototype to production short and verifiable.
Who is behind it
Kontrollfeld is a small team that works directly with its clients. The agency was founded and is technically led by Jakob Lipps (Founder & Technical Lead), who has been building web and AI systems for B2B clients for over a decade — from Drupal platforms to RAG pipelines and MCP servers.

The flat structure is deliberate: short paths, shared responsibility for both implementation and operation.
Who we work with
We work with mid-sized companies and institutions that want to use AI productively while keeping data sovereignty. In projects like these, technical decision-makers and budget owners sit at the same table — both have to stand behind the solution. So we explain architecture and trade-offs in a way that makes sense to both sides, rather than hiding behind jargon.
Where we come from
Our project experience reaches beyond AI integration alone. We have worked in, among others, these sectors:
- Media and publishing
- Market and opinion research
- Culture and events
That range means we know the usual friction points: heterogeneous legacy systems, distributed data, and the demand to fit AI reliably into existing workflows. It shapes how we set up projects — pragmatic, integration-aware, and with an eye on later operation. We rarely start on a greenfield; we work with what is already running and extend it where it makes a measurable difference.
In short
- Kontrollfeld is an AI agency from Berlin for AI and automation systems in B2B.
- We build production-ready systems — RAG, MCP, SSO with Keycloak, WebRTC, architecture — and we operate them.
- Self-hosted, auditable, with no sales layer between client and implementation.
