Innovators at these companies trust us
The local challenge
Dortmund’s automotive suppliers are caught between growing data volumes, rising quality requirements and pressure to optimize production. Many teams know which problems could be solved with AI — but the hurdle is production readiness: models, data pipelines and integrations must be robust, scalable and secure.
Why we have the local expertise
Our headquarters are in Stuttgart, but we travel regularly to Dortmund and work on site with customers. This direct presence allows us to understand production lines, IT teams and logistics processes up close — from the shop floor to management meetings. We bring technical depth and a founder‑mindset that enables fast decisions and direct implementation.
We understand how important regional networks are: Dortmund is a logistics and IT hub in North Rhine‑Westphalia, and our projects draw on experience gained in similar German production environments. That is why we design solutions to fit existing MES/ERP systems, the security requirements of German manufacturing and the compliance expectations of OEMs.
Our approach is pragmatic: instead of long roadmaps we deliver proofs of concept in days, followed by scalable engineering plans. On site in Dortmund we work with interdisciplinary teams to address latency, data sovereignty and operational reliability early on — minimizing risks during integration into production environments.
Our references
For automotive use cases our project with Mercedes Benz is particularly relevant: we developed an AI‑based recruiting chatbot that uses NLP for automated candidate communication — 24/7 availability, automated preselection and integration into existing HR processes. The experience demonstrates how AI creates robust communication channels and automates recurring processes.
From the manufacturing environment we bring references such as STIHL and Eberspächer that provide valuable insights. At STIHL we supported several projects from saw training to ProTools and worked on solutions spanning research, product development and market launch. At Eberspächer we implemented AI‑driven noise‑reduction and optimization approaches in manufacturing processes. These projects show how Predictive Quality and plant optimization succeed in German manufacturing operations.

AI engineering for automotive OEMs & Tier‑1 suppliers in Dortmund
Automotive manufacturing in North Rhine‑Westphalia is changing rapidly: data streams from test benches, MES, CAD/PLM systems and logistics platforms have offered potential for years that can only now be productively exploited with modern AI techniques. Dortmund, as a logistics and software location, provides ideal conditions to anchor data‑driven quality assurance and process automation.
Market analysis and strategic relevance
Today the market demands not only proofs of concept but production readiness. OEMs and Tier‑1 suppliers see AI as a lever for cost reduction, quality improvement and resilience in the supply chain. In Dortmund supply chains are dense and often international — Predictive Quality can reduce scrap, minimize rework and thereby increase delivery reliability.
At the same time the pressure to digitize dominates the agenda: IT competence centers and logistics providers in the region drive innovations that suppliers must adapt to. AI engineering here is more than model training: it is architecture, data ethics, operational security and seamless integration into existing production IT.
Concrete use cases for automotive in Dortmund
The opportunities are tangible: AI Copilots for engineering help engineers validate drawings and specifications faster; they summarize change requests, suggest test sequences and speed up reviews. Copilots reduce time‑to‑decision and increase the consistency of technical assessments.
For manufacturing quality, Predictive Quality is key: models analyze sensor data from test benches and production lines, detect patterns that indicate imminent defects and provide preventive action recommendations — often before a human notices the deviation. Such systems significantly reduce downtime and scrap rates.
Other relevant cases include documentation automation and knowledge systems: from repair manuals to compliance documentation, LLM‑powered pipelines can extract, standardize and transfer texts into internal knowledge bases so that service teams and production can work faster.
Implementation approach: from PoC to production
We recommend a staged rollout: first a focused PoC that validates a concrete hypothesis — for example reducing rework through Predictive Quality. The PoC tests data quality, suitable models, latency requirements and integration points. It is important to define the metrics (KPIs) clearly: scrap reduction, MTTR, throughput increase or cost per run.
After a successful PoC comes production rollout: data engineering for robust ETL pipelines, secure model serving architectures (on‑premise or private cloud), monitoring, retraining factories and access controls. In Dortmund a hybrid architecture is often sensible — sensitive data stays local, less critical workloads can be scaled externally.
Technology stack and infrastructure
Our modules include custom LLM applications, internal copilots & agents, API/backend integrations (OpenAI, Groq, Anthropic), private chatbots without RAG, data pipelines & analytics, programmatic content engines as well as self‑hosted AI infrastructures with tools like Hetzner, Coolify, MinIO, Traefik and enterprise knowledge systems on Postgres + pgvector. These components are modular building blocks: not every deployment needs all components, but the architecture must support them.
For Dortmund we often recommend self‑hosted options: local compute reduces latency, meets data sovereignty requirements and simplifies certification. At the same time we provide interfaces to cloud models where external models make economic sense.
Integration, security and compliance
Integrations are the most common stumbling block: unstructured data in PLM systems, different sensor formats or proprietary interfaces require careful data engineering. We design ETL pipelines that automate data cleaning, normalization and semantic enrichment — creating reliable training data and production metrics.
Security is not an add‑on: access rights, model governance, audit logs and data masking are integral parts of our engineering process. For automotive customers we follow industry standards and assist with certification requirements, for example in the context of ISO norms and internal quality specifications.
Change management and team requirements
The technical part is only half the job. AI projects succeed when processes, skills and responsibilities are adapted. We work with engineering, IT and production departments, train operators and produce operational documentation, runbooks and playbooks. Internal copilots support teams with context‑sensitive assistance and thereby increase acceptance.
For long‑term success we recommend establishing a small, cross‑functional AI operations team: data engineers, ML engineers, DevOps specialists, domain experts and a product owner. This structure enables rapid iteration and sustainable operations.
Success criteria, common pitfalls and ROI
Success is measured by real metrics: avoided scrap costs, reduced downtime, faster engineering throughput or lower personnel costs through automation. Typical pitfalls are unrealistic expectations of models, unclear data ownership and lack of monitoring. We address this through early KPI definition, structured data ownership and observability for models.
ROI calculations are based on realistic scenarios: a successful Predictive Quality deployment often pays off within months through less scrap and reduced rework, while copilots can significantly reduce engineering time per change request. We provide concrete business cases for Dortmund‑specific plants and supply chain configurations.

Frequently Asked Questions
A proof of concept (PoC) for Predictive Quality can often be started within days to weeks, provided the basic data access is available. First we check data availability and quality: sensor data, test protocols, MES logs and material master data are the starting point. If these data are structured and accessible, we build a minimal pipeline that cleans the data and prepares it for initial models.
The PoC focuses on a clearly defined question — for example predicting a specific error type or detecting process deviations on a particular line. We define KPIs together with your team; typical metrics are precision/recall on error events, reduction of rework or projected savings.
Technically we deliver an initial model within the PoC, an evaluation environment and a short demo interface so that production managers and engineers can understand and assess results. In parallel we develop an implementation plan for production, including infrastructure, monitoring and governance if the PoC is successful.
Practically for Dortmund this means: we come on site, evaluate the data landscape, align on KPIs and deliver a runnable prototype in a short time — without requiring large upfront investments. The critical path is usually clarifying access rights and data exchange; these points should be addressed early.
For production environments in Dortmund we recommend a hybrid, modular architecture: sensitive data and latency‑critical services remain on‑premise, while non‑critical batch workloads or supplementary training jobs can be offloaded to a private cloud or trusted data centers. Self‑hosted components like MinIO for object storage, Traefik for routing and tools like Coolify for deployment provide control and automation.
Important elements are a stable data lake, orchestrated ETL pipelines, containerized model‑serving infrastructure and observability stacks for logging, metrics and model drift detection. If needed, we rely on specialized inference hardware to minimize latency in production.
Data sovereignty and compliance are central requirements: role and permission management, encryption at rest and in transit, and audit logs must be integrated from the start. For many automotive use cases a penetration test and security acceptance are recommended before go‑live.
For Dortmund it is also important to connect to local ops teams: we plan handovers or runbooks so your local IT teams can sustainably operate the infrastructure. If desired, we provide a transition plan that includes knowledge transfer and, if necessary, managed services.
LLM copilots succeed when they replace or accelerate concrete tasks — for example creating test protocols, summarizing change requests or suggesting test sequences. Integration starts with selecting relevant data sources: CAD/PLM data, change requests, test reports and SOPs form the context for a copilot system.
Technically we build API layers that contextualize LLMs: query pipelines filter relevant documents, knowledge systems (Postgres + pgvector) provide embeddings for fast access, and agents coordinate multi‑step workflows. It is important that copilots are integrated into the tools your engineers already use — e.g. as a plugin in PLM systems or as a chat interface in the engineering portal.
Governance and review processes are equally important: copilots should provide suggestions, but approval processes and responsibilities remain with humans. Training and clear use cases increase acceptance; we provide training materials and live workshops for engineering teams in Dortmund.
In practice we start with a limited scope (e.g. change review in one product family) and expand functionality once KPI improvements are demonstrated. This minimizes disruption to daily operations and delivers quickly measurable value.
Suppliers in the region often struggle with heterogeneous data sources: different machine vendors, proprietary sensor formats, fragmented test protocols and inconsistent product identifiers. These inconsistencies prevent robust model training and delay deployments.
Our solution begins with on‑site data discovery and profiling: we identify critical data fields, cleansing needs and gaps. Common measures include standardizing field names, harmonizing timestamps, outlier handling and enriching data with context (e.g. batch information, material numbers).
Building on that we develop ETL pipelines that guarantee repeatable data preparation processes. These pipelines are versioned, observable and automated so data quality is continuously monitored. Additionally we implement data contracts between IT and production teams to clarify responsibilities.
Finally we recommend feedback loops: model predictions are compared with real outcomes and lessons learned feed back into data preparation. This creates a cyclical improvement process that incrementally raises data quality and enables stable AI performance over the long term.
ROI depends heavily on the use case: Predictive Quality has different levers than an engineering copilot. We start with a baseline analysis of current costs: scrap rates, rework times, downtime costs and time spent on recurring engineering tasks. This baseline enables realistic savings forecasts.
Typical calculations include direct effects (e.g. reduction of scrap by X% multiplied by unit costs) and indirect effects (e.g. faster time‑to‑market due to fewer rework cycles). We model conservative, realistic and optimistic scenarios to give decision makers a range of possible outcomes.
Another point is time‑to‑value: projects with quick wins (PoC in days, production within months) often have high IRR. Projects with longer build‑up and integration needs require more detailed total cost of ownership calculations, including infrastructure and operational costs.
We deliver complete business cases based on your operational data and including sensitivity analyses. These business cases serve as the basis for investment decisions and help set realistic budgets and timelines.
Successful AI projects require a cross‑functional team: domain experts from production and quality, data engineers to build pipelines, ML engineers for models, DevOps for operations and IT security for governance. The team is complemented by a product owner or sponsor from management who sets priorities.
Organizationally it is important to define clear decision paths and data responsibilities. Who decides on data release? Who is responsible for model approvals? These questions should be clarified before project start. Small, autonomous units with clear success criteria often work more effectively than large, centralized programs.
Training is a key factor: operators and engineers need training on how copilots or dashboards are integrated into their daily work. We support with workshops, on‑the‑job training and training materials so changes are used sustainably.
Finally we recommend overcoming organizational hurdles through pilot projects: quick successes build trust, and successful pilots are often the catalyst for broader organizational change.
