Innovators at these companies trust us
Local challenge
The manufacturing landscape around Dortmund stands between traditional production and digital transformation: outdated documentation processes, fragmented data landscapes and manual quality inspections slow throughput times and increase scrap. At the same time, margin pressure and supply chain risks threaten if companies do not modernize technically.
Why we have the local expertise
Reruption is based in Stuttgart; we are not a Dortmund office, but we travel to Dortmund regularly and work on site with customers to integrate solutions directly into production. Our work doesn’t start with presentations, but at workbenches, in quality labs and in procurement meetings — where real processes run.
Our team combines rapid engineering sprints with operational responsibility: we build prototypes, test them in live environments and lay the technical foundation for productive operation. This is especially important in regions like North Rhine-Westphalia, where manufacturing, logistics and software are closely linked.
Our references
In the manufacturing area we have worked, among others, with STIHL on several projects, from saw training to pro tools and saw simulators — projects that bridge customer research, product development and production application. This work shows how to turn technical prototypes into real training and production tools.
For Eberspächer we delivered AI-powered solutions for noise analysis and process optimization: a classic example of how manufacturing data can be translated directly into quality and efficiency. We also support tech and go-to-market work with companies like BOSCH, where we accompanied display technologies and spin-off strategies.
About Reruption
Reruption was founded because companies should not simply be disrupted — they must reinvent themselves. Our Co-Preneur approach means we work like co-founders: we take ownership, drive technical execution and stay in the project until real results are running.
For Dortmund manufacturers this means concretely: we bring AI engineering, from custom LLM applications to self-hosted infrastructure, deliver fast proofs-of-concept and accompany production readiness — always with an eye on compliance, data sovereignty and scalable architecture.

AI for manufacturing (metal, plastic, components) in Dortmund: a deep dive
The transformation from steel to software in Dortmund is more than a slogan: it is an operational imperative. Manufacturers today must simultaneously improve production quality, supply chain stability and procurement efficiency. AI engineering is not an end in itself but a tool to move concrete production metrics: increase OEE, reduce scrap, shorten lead times.
Market analysis: North Rhine-Westphalia remains a production hub with a high density of suppliers, machine builders and logistics providers. In Dortmund, manufacturing and logistics are closely located, so data-driven improvements in production have a direct effect on warehousing and shipping. Local demand today targets solutions that perform inline quality checks, automate production documentation and partially autonomize procurement processes.
Concrete use cases
1) Quality Control Insights: camera systems, vibration data and process metadata are turned into early error indicators by ML models. In practice this means: less rework, faster root-cause analyses and automated inspection protocols that integrate seamlessly into MES/PLM.
2) Workflow automation and copilots: internal copilots support production managers, maintenance teams and buyers in multi-step workflows — from spare parts ordering to approval steps to production ramp-up coordination. Such agents reduce response times and standardize decisions along the value chain.
3) Procurement copilots: AI-powered procurement assistants analyze order history, supplier performance and market prices and suggest optimized order quantities and supplier combinations. For medium-sized suppliers in Dortmund this can reduce tied-up capital and increase supply security.
4) Production documentation & knowledge management: with natural language processing, handwriting, inspection protocols and older paper records can be digitized and transferred into an enterprise knowledge system. Combined with pgvector-backed search, this creates a searchable production memory.
Implementation approach
Proof-of-value first: we start with tight use-case scoping, predefine clear KPIs (e.g. scrap rate, lead time, cost per quality inspection) and deliver a prototype within days. This reduces risk and provides quick decision support.
Architecture: production-grade AI requires robust data pipelines, model versioning, observability and a security concept. We rely on modular backends (API/backend development with integrations to OpenAI/Groq/Anthropic), PostgreSQL + pgvector for knowledge systems and optional self-hosted stacks (e.g. Hetzner, MinIO, Traefik) for data-sensitive users.
Technology stack and integrations
Model and infrastructure agnosticism is crucial: not every solution needs an LLM, not every dataset is suitable for on-premise training. For chatbots and internal copilots we use retrieval techniques without RAG when strict data ownership is required, or hybrid architectures for fast iteration.
Our modules range from custom LLM applications through private chatbots to programmatic content engines for documentation and SEO. The API layer ensures standardized connectivity to ERP, MES and PLM systems so that responses can automatically trigger actions in existing workflows.
Success factors
1) Data quality: many manufacturers underestimate the time required for data cleansing and mapping. We explicitly plan for this chapter and deliver early tools for ETL and monitoring.
2) Process integration: AI must embed decisions into existing approval processes, not run alongside them. Copilots should make suggestions, not authoritative decisions — until governance is established.
3) Change management: production teams must understand AI results and develop trust. We accompany training, shadowing phases and deliver understandable dashboards and error explanations.
Common pitfalls and how to avoid them
Typical mistakes are overfitting on too-small datasets, missing governance and unrealistic ROI expectations. We address these problems with conservative metrics, A/B tests in production and clear milestones that link technical maturity with operational benefit.
Another mistake is excessive complexity: systems are often built too generically. Instead, we recommend modular components that can be extended step by step — for example a quality model that is later connected to a procurement copilot.
ROI, timeline and team requirements
A realistic roadmap starts with a 4–8 week PoC (proof of concept), followed by a 3–6 month pilot that is embedded into production processes. Initial economic effects (reduced scrap, shorter inspection times) are often visible during the pilot.
Implementation requires a small interdisciplinary team: a product owner from the company, a data engineer, an ML engineer, a backend developer and a change manager. Reruption can co-fill these roles as a Co-Preneur or embed them into the customer organization.
Security, compliance, operations
Data protection and operational security need specialized treatment: on-premise infrastructure, encrypted storage layers (MinIO), network gateways (Traefik) and access controls are part of every roadmap. We plan backup and rollback strategies as well as monitoring for models in operation.
Finally, maintainability and cost per inference are central metrics. We measure not only accuracy but also latency, cost per request and maintenance effort to ensure sustainable economics.
Summary
For manufacturers in Dortmund, AI engineering is not a luxury but a strategic investment: from inline quality inspection to procurement copilots to automated product documentation, AI systems change how production operates. With a pragmatic, modular approach, quick wins can be achieved and the foundation for long-term automation can be laid.

Key industries in Dortmund
Dortmund was long shaped by steel and mining; structural change has turned the city into a modern location for logistics, IT and manufacturing companies. In particular, manufacturing for metal and plastic components benefits from proximity to supplier networks and large logistics hubs that enable fast response times and flexible supply chains.
The logistics sector acts as a backbone for production companies: warehousing, picking and transport processes are closely linked to production control. For AI solutions this means: demand forecasting and route optimization models deliver direct value because they shorten delivery times and reduce inventory costs.
IT companies in the region drive digitization forward and provide talent pools for software and data engineering. This gives manufacturers the opportunity to staff AI projects regionally and build knowledge long-term. The local IT community also facilitates access to modern cloud and on-premise operating models.
Insurers and energy providers are also important partners: risk models, insurance data and energy consumption analyses can be connected with manufacturing data to create more sustainable and lower-risk production processes. AI can help optimize energy usage and make insurance costs more transparent.
For mechanical engineering and component manufacturing, the local industrial diversity means short innovation cycles and high demands on quality and compliance. AI-powered inspection processes, predictive maintenance and automated documentation face high demand here for reliable, industrialized solutions.
The regional innovation pressure also acts as an opportunity: manufacturers, logisticians and software providers in Dortmund increasingly work together in ecosystems. Successful AI projects are therefore often not standalone solutions but integration projects that connect multiple players and data sources and thus create systemic value.

Important players in Dortmund
Dortmund’s economic identity is based on strong, established companies and a growing network of mid-sized and tech firms. This mix creates a dynamic environment for AI innovation because demand, data and implementation potential exist together.
Signal Iduna is an important regional insurer for manufacturers when it comes to risk assessment, claims management and insurance data. Collaboration between insurers and manufacturers often opens up data-driven services around prevention and maintenance.
Wilo is an example of a Dortmund-based mid-sized company with global reach that focuses heavily on efficiency and quality in pump and building technology. For companies like Wilo, predictive maintenance, energy optimization and manufacturing automation are central topics where AI delivers direct operational value.
ThyssenKrupp remains a symbol of the region’s industrial depth: as a major employer and technology provider, ThyssenKrupp shapes supply chains and innovation networks. AI applications that combine material quality, production flow and logistics have particularly high leverage here.
RWE plays a central role in energy supply and infrastructure. Manufacturers in Dortmund benefit from partnerships that enable energy efficiency projects, load management and the integration of renewables into production processes — all areas where data-driven models can reduce costs and CO2 footprint.
Materna as an IT service provider and system integrator brings expertise in project management and software implementation. Such partners are often the bridge between research, development and the productive introduction of AI solutions in manufacturing environments.
Together these players form an ecosystem where production companies, service providers and infrastructure partners collaborate. For AI projects this creates an advantage: local integration routes are short and pilots can be quickly scaled to larger rollouts.

Frequently Asked Questions
A proof-of-concept (PoC) can, for a clearly defined use case, often be realized within 4–8 weeks. The decisive factors are data access, clear KPIs and the availability of an operations contact who can make decisions. In Dortmund we often work on site to clarify machine connections and data interfaces directly — this greatly accelerates implementation.
At the start we scope the use case very tightly: input and output definitions, tolerance limits and metrics are defined in advance. On this basis we build a minimal prototype that processes realistic data and delivers initial results, such as error detection or simple automations.
Technically, the PoC typically includes data pipelines (ETL), an initial model or a retrieval layer for knowledge systems and a simple integration layer to existing systems (MES/ERP). We also provide a performance analysis: runtime, cost per inference and robustness against data fluctuations.
Practical tips: plan time buffers for data cleansing and internal coordination. A PoC is a learning loop — the results often provide clear indications of what data quality or process adjustments are needed to make the jump to productive operation.
Self-hosted infrastructure addresses three central requirements: data sovereignty, operational security and cost control. For manufacturers that process sensitive production data or proprietary designs, the ability to run models and data locally is often a decisive advantage over cloud-only approaches.
Technically, we rely in such scenarios on components like Hetzner for hosting, MinIO for object-storage-like requirements, Traefik as a gateway and container orchestration with solutions like Coolify. This enables scalable deployments that are still fully embedded within the company’s security perimeter.
Another advantage is reduced latency: local inference minimizes response times for production copilots that must deliver real-time decisions or recommendations. In addition, self-hosted setups allow fine-grained control over updates, backups and access rights — important for audits and certifications in manufacturing companies.
For Dortmund companies we recommend a hybrid strategy: sensitive workloads on-premises, less critical models in controlled cloud environments. This preserves flexibility and cost optimization without compromising compliance.
Integration happens on several layers: data layer, API layer and UX layer. First, relevant data is extracted from MES/ERP and converted into standardized formats. This ETL layer is often the most time-consuming part because field names, protocols and timestamp formats must be harmonized.
On the API layer we build middleware that translates copilot requests into ERP transactions and vice versa. This way a copilot can, for example, trigger a supplier inquiry, generate an approval request or prioritize production orders while ERP logs and audit trails remain intact.
The UX layer is crucial for acceptance: copilots should be integrated into users’ working environment — whether a dashboard in the MES, a chat widget in the control center or mobile notifications for maintenance teams. Decision suggestions must be transparent, with explanations and source references so operators can follow the recommendations.
Finally, governance is important: which actions may the copilot perform automatically and which only suggest? These rules are defined in coordination with operations management and IT and are opened step by step as trust is built.
For reliable quality inspections multimodal data is often most effective: high-resolution images, process parameters (temperature, pressure, speed), machine data (vibration, power consumption) and manual inspection protocols. The more relevant signals combined, the more robust the fault detection.
Historical depth is also important: models benefit from datasets that cover typical production variants and fault cases. When rare errors occur, synthetic data augmentation or targeted annotations are needed to prevent models from over- or underfitting.
Another criterion is metadata quality: traceability to batch numbers, supplier information and machine IDs enables both root-cause analyses and more precise corrective actions. Without this contextual data the diagnosis often remains incomplete.
In practice we start with a data mapping workshop, identify quick wins and then build ETL pipelines with monitoring. This shows quickly whether the available data is sufficient for a productive quality use case or whether additional sensors or processes are required.
Economics depend on the use case and metrics. Typical levers are reduction of scrap, shorter inspection times, reduced setup times and improved on-time delivery. These effects are immediately monetizable: less rework, lower material consumption and reduced inventory costs.
A realistic approach assumes a PoC (4–8 weeks), a pilot (3–6 months) and a scaling phase. Initial savings often occur during the pilot: reduced inspection times or avoided error costs can partially cover the investment within a year.
Clear KPIs and baseline measurements before project start are important. We help define KPIs so they can be measured operationally — e.g. scrap rate per shift, time per quality inspection or delivery punctuality. Such metrics make ROI calculations reliable.
We also offer financing and phased implementation: instead of a large upfront investment we show minimum viable products that deliver immediate value and are expanded step by step. This makes the investment manageable and predictable.
Change management is often the key to the sustainable introduction of AI. Technical solutions alone are not enough; employees must adapt processes, understand system recommendations and build trust. Without accompanying measures, systems often remain island solutions that do not deliver the expected benefits.
A proven approach includes training, shadowing phases, regular feedback loops and the involvement of key users from production, quality and procurement. These users become champions who test the new system in daily operations and explain the benefits to colleagues.
Transparency helps: explainable models, understandable suggestions and a clear escalation pattern for error cases reduce fears and build trust. Dashboards that visualize metrics and root causes further support acceptance.
Reruption works as a Co-Preneur: we bring not only technology but also support for organizational adaptation. On-site work in Dortmund is crucial because cultural and process nuances become visible directly and can be incorporated into the solution.
