Innovators at these companies trust us
The local challenge
Stuttgart's manufacturing companies are under pressure: rising quality expectations, volatile supply chains and the need to sustainably digitize engineering knowledge. Many companies have ideas but lack a robust route to production-ready AI systems — the risk is siloed solutions that are neither scalable nor maintainable.
Why we have the local expertise
Stuttgart is our home base – we are located here, work daily with suppliers, SMEs and large corporations, and know the region's particularities first-hand. Our teams are regularly on site, understand production processes from press lines to assembly, and speak the language of plant management, quality management and IT.
We combine fast engineering cycles with business responsibility: our Co‑Preneur approach means we don't just advise, we build solutions with entrepreneurial accountability that go into the line — from measurement to integration with SAP landscapes and shopfloor systems.
Our references
For automotive manufacturing we worked with Mercedes‑Benz on an NLP-based recruiting chatbot, an example of how reliable automation operates 24/7 in critical HR processes and leverages interfaces to existing systems. Such projects demonstrate our experience handling sensitive data and complex integrations.
In manufacturing technologies we implemented multiple projects with STIHL over two years — from training solutions to production-near tools — and collaborated with Eberspächer on AI-supported noise reduction in manufacturing processes.

AI engineering for manufacturing in Stuttgart: an in-depth guide
The next wave of competitiveness in manufacturing will be decided by AI engineering. In Stuttgart, the center of automotive suppliers, mechanical engineering and industrial automation, it's not about research labs but about production-ready systems that are stable, secure and maintainable. Here we describe how such systems are created — from idea to ongoing integration.
Market analysis and urgency
Baden‑Württemberg is characterized by deeply integrated value chains: supply chains are dense, variant diversity is high, and takt times are tight. This means small improvements in quality or throughput have large effects. AI can reduce downtime, minimize scrap and accelerate decision processes — provided the solution is tailored to production conditions.
The urgency is increasing: international competitors are investing heavily, skilled workers are becoming scarcer, and regulatory requirements are rising. Companies that build AI engineering as a strategic capability secure sustainable efficiency gains and better time-to-market abilities.
Concrete use cases for metal, plastics and components
In metal manufacturing, visual quality inspections, predictive maintenance for presses and adaptive process control are central application areas. AI models can detect microscopic surface defects, predict tool wear and adjust control parameters in real time.
For plastics manufacturers, process monitoring, granulate quality detection and cycle time optimization are typical use cases. Component manufacturers benefit particularly from procurement copilots that compare supplier offers, forecast material availability and automate ordering patterns.
Across the board, enterprise knowledge systems are gaining importance: technical documentation, test reports and maintenance manuals can be prepared with vector databases and LLM-based interfaces so engineers have quick access to relevant knowledge.
Implementation approach: from PoC to production
A successful path begins with a clearly defined PoC that examines technical feasibility, data situation and interfaces. We recommend a tight schedule: 1–2 weeks of scoping, 2–3 weeks of rapid prototyping, measurement of core metrics and then an 8–12 week sprint to production readiness with monitoring and a rollout plan.
It is essential to parallelize work: data engineering, model selection, backend APIs and UX should be advanced simultaneously. Only then do production-ready solutions emerge in months instead of years. Our AI PoC package is explicitly designed for this: a working prototype plus a roadmap for production.
Technology stack and architecture options
For production environments we prefer robust, observable architectures: Postgres with pgvector for vector search, self-hosted instances on Hetzner combined with Traefik for secure deployment, MinIO for object storage and Coolify for deployment. At the same time we keep cloud APIs (OpenAI, Anthropic, Groq) as integration options when latency, cost or data sovereignty allow.
For LLM applications we choose between small local models for latency-critical, private workloads and hybrid approaches for complex NLP tasks depending on the use case. It's important that the system remains model-agnostic: interchangeability avoids vendor lock-in.
Security, compliance and data architecture
Production data is sensitive: IP, design data and personal information must be protected. Self-hosted infrastructure minimizes outsourcing risks; at the same time clear access concepts, audit logs and encryption are mandatory. We create compliance templates that are aligned with the plant IT team.
Another aspect is data quality: historical sensor data must be cleaned, annotated and enriched with metadata. Without clean data engineering there are no meaningful training datasets; models then do not deliver reliable results.
Change management and organizational requirements
Technology alone is not enough: AI changes roles and processes. Leaders must decide which decisions are automated and which remain escalated. We support training, design of copilot workflows and onboarding of operations and IT teams to ensure acceptance.
A practical pattern is the "Engineering Concierge" model: a small, permanent team that initially operates the solution, transfers knowledge and hands over operational responsibility to internal teams within 6–12 months.
Success factors and common pitfalls
Success factors are clear metrics (TPR, scrap rate, throughput time), robust interfaces to MES/ERP and a culture that allows experimentation. Common mistakes are unrealistic expectations, missing data pipelines and lack of maintenance planning. Without monitoring, models become stale quickly.
That's why we build observability in: telemetry for model performance, drift detection and automated retraining triggers are part of every production architecture.
ROI, timelines and scaling
Quick savings often lie in reducing scrap and manual inspection efforts; typical payback periods are 6–18 months, depending on production volume and implementation scope. A detailed business case is based on throughput gains, material savings and reduced downtime.
Scaling succeeds when core components like data lake, vector store and authentication are planned cleanly once. Then use cases can be added modularly and country-specific requirements addressed without redeveloping the base.
Team structure and roles
Production-ready AI requires a cross-functional team: data engineers, ML engineers, backend developers, DevOps/infra, domain experts and a product owner from manufacturing. Governance remains with the customer; we act as a Co‑Preneur extension until internal teams can take over.
A typical launch resource plan includes 2–4 engineers, 1 product owner and 1 domain expert for the first 3 months — plus support for operations and monitoring during the transition phase.

Key industries in Stuttgart
Stuttgart has long been the industrial heart of Germany: the automotive industry has its historical roots here, mechanical engineering shapes the supply chains, and precision manufacturers deliver components worldwide. This density of know‑how and supplier networks makes the region unique, but also creates complex coordination tasks that are ideal for intelligent automation.
The mechanical engineering sector in and around Stuttgart is characterized by small-batch production, high quality requirements and many customer-specific adjustments. For such structures AI-supported quality assurance processes that link visual inspection and process monitoring are a good fit to detect scrap early.
The automotive industry drives modularized production and just‑in‑time supply chains. Here, predictive maintenance, parts classification and procurement copilots are valuable levers: they reduce lead times, improve supplier evaluation and automate approval processes.
Medical technology manufacturers in the region demand the highest documentation standards and traceable production steps. AI can help automate compliance documentation, link test protocols and generate audit trails — tasks that are time-consuming and risky when done manually.
Industrial automation and machine builders are both users and providers of AI technology. For them opportunities arise in production-near applications: adaptive control, autonomous test rigs and digital twins that simulate and optimize manufacturing processes.
Plastics manufacturing, often closely linked to automotive and medical technology, benefits from process monitoring and raw material quality checks. AI can enable short-term production adjustments, forecast material consumption and significantly reduce scrap costs.
Another feature of the region is the strong connection between research and industry: universities and Fraunhofer institutes provide innovations that can be industrialized quickly. Companies that integrate AI engineering into their product development can leverage this advantage.
In summary: industries in Stuttgart share high quality expectations, complex supply chains and a need for data sovereignty — ideal conditions for ambitious but focused AI engineering.

Frequently Asked Questions
A focused PoC can typically deliver first results within 4–6 weeks. The initial phase consists of scoping and data capture: we define inputs, outputs, metrics and the minimally necessary data volume. This phase is crucial because it determines whether the problem is data-driven solvable and which measurements define success.
In weeks 2–4 we build a rapid prototype that processes real data — typically a model for image or sensor data analysis coupled with a small dashboard. This prototype is not a pretty demo but a tool to measure quality metrics (e.g., detection rate of defects, false-positive rate).
From week 4 we evaluate performance, robustness and cost per inference. If the metrics are right, we plan a production sprint (8–12 weeks) covering scaling, monitoring and integrations. Availability of labels and the MAP (Measurement, Annotation, Pipeline) is decisive — the cleaner the data, the faster the validation.
Practical recommendation: start with a use case that has clearly measurable KPIs and requires no more than two integration points (e.g., camera + MES). This reduces risk and achieves tangible business outcomes faster.
Self‑hosted infrastructure is not inherently mandatory, but in many cases it makes sense — especially in manufacturing where data sovereignty, latency and compliance play a major role. Self-hosted solutions on Hetzner or private datacenters allow sensitive design data and production metrics to remain under your control.
The advantage is lower dependency on third parties, better cost predictability for extensive inference loads and direct integration into the local network. At the same time self‑hosting requires personnel resources for operation, monitoring and security — aspects that a migration or operations plan must address early.
Hybrid approaches are pragmatic: time-critical or data-sensitive workloads on‑premises, research-intensive training phases optionally in the cloud. Our work focuses on model-agnostic architectures so customers can later switch between local and cloud hosting without fundamentally changing the application.
For companies in Stuttgart we recommend evaluating regulatory requirements, network latency and ongoing operational costs. We support PoCs for self-hosted setups, including deployment automation and backup strategies.
Integration is less a technical secret than an organizational project. First it is important to map: which data flows should be handled automatically, which approvals are required, and where are the relevant interfaces (e.g., SAP, Infor, proprietary MES). Based on this we define APIs and data adapters for secure, transaction-capable connections.
Technically we use RESTful APIs, event-driven patterns and, when necessary, direct database connections with strict access rules. For latency-critical processes an edge component that performs preprocessing and only sends aggregated results to central systems is recommended.
On the organizational level it's important to set governance policies: who is allowed to execute which actions via the copilot? Which workflows require human review? These questions determine the roles model and audit functions we build into the solution.
In Stuttgart we regularly work on site with IT and production managers to plan integrations securely and carry out rollouts in shifts. Small‑steps rollouts reduce risk: initially only in one line or shift, then progressively expanded.
Costs vary greatly by use case: a simple visual inspection copilot can be technically validated with modest means (PoC €9,900), while a fully integrated, company-wide platform can require significantly higher initial investments. Key cost blocks are data engineering, model training, integration, infra operations and change management.
ROI usually comes from direct savings (reduced scrap, less rework), efficiency gains (faster inspection cycles, reduced downtime) and indirect effects (better supplier ratings, shorter time‑to‑market). Typically our clients see payback periods between 6 and 18 months with clear production metrics.
For reliable statements we recommend a business case that runs scenarios: conservative (only direct savings), realistic (plus process optimizations) and optimistic (scaling to additional lines). This allows investment decisions to be made based on data.
We start with a PoC, deliver measurable KPIs and a production roadmap that transparently shows effort and expected benefits. This reduces uncertainty and provides a basis for investment approvals.
A common pitfall is an unclear problem definition: many projects start with the technology in the foreground instead of a clear business problem. Without quantified targets ambitions arise but no measurable results. Another classic is insufficient data quality: sensor noise, missing labels and conflicting metadata prevent robust models.
Technical debt accumulates when prototypes are taken into production without maintainability, monitoring or versioning. This leads to operational issues and loss of trust. Therefore it's important to plan observability, retraining pipelines and governance from the start.
Organizationally projects often fail due to lack of involvement of operations and maintenance staff. Acceptance is created when users are involved in designing the copilots and the systems actually make daily work easier — not replace it.
Our recommendation: targeted scoping, iterative delivery, and a transfer plan for operations. This minimizes risk and ensures sustainable value.
As a Stuttgart-based company we are regularly on site and work closely with production, IT and quality stakeholders. Our Co‑Preneur approach means: we take entrepreneurial responsibility, work within your P&L structures and drive projects from prototype to live operation.
Practically, collaboration begins with an on-site scoping workshop followed by fast prototypes that we test together on the line. We place particular emphasis on data security, interfaces to existing MES/ERP systems and training of operations personnel.
Our regional experience enables us to assess local suppliers and process specifics — for example typical machine vendors, control systems and test procedures common in Baden‑Württemberg. This saves time in the implementation phase and reduces adaptation effort.
In the long term we support the transfer to your internal teams: documentation, operational handover and training are integral parts of our projects. This ensures you build competence internally and can operate independently.
