Innovators at these companies trust us
Concrete local problem
In Cologne's laboratories and production facilities, the abundance of process documentation, safety regulations and regulatory requirements often leads to information silos, manual workflows and delayed decisions. Without robust, secure AI implementations, risks arise in compliance, safety and quality.
Why we have the local expertise
Reruption comes from Stuttgart, but we are not an agency that only consults remotely: we travel to Cologne regularly and work on site with clients — directly at lab benches, in production halls and in the IT departments of the Rhine metropolis. This presence allows us to see processes with our own eyes, understand data flows and test immediate prototypes in real environments.
Our Co-Preneur philosophy means: we work like co-founders, not like external observers. In Cologne we combine this mindset with a technical focus: from day one we build production-ready pipelines, secure models and self-hosted infrastructure that meet the strict requirements of the chemical and pharmaceutical industries.
Our references
Technical references are crucial for the chemical and process industries: with TDK we worked on a PFAS removal technology that paved the way for a spin-off — an example of how technological validation and scaling can interact. Projects like this demonstrate our understanding of chemistry-related processes and regulatory complexity.
Eberspächer was a project where we implemented AI-supported analysis and optimization in manufacturing processes; similar methods can be directly transferred to process parameterization and quality control in chemical plants. At STIHL we conducted extended product development cycles, training solutions and prototyping — experience that translates to lab and production processes.
For document-centric challenges we delivered an AI-supported document search and analysis solution with FMG, a use case that is immediately applicable in pharma labs with extensive testing and approval documentation.

AI engineering for chemical, pharmaceutical & process industries in Cologne: a comprehensive guide
The use of AI in chemical production processes, in pharma laboratories or in adjacent process industries is not a luxury but a competitive factor. Cologne as a location offers a particular mix of industry, logistics and services — this creates opportunities but also complexity: heterogeneous IT landscapes, strict compliance requirements and often fragmented data architectures.
Production-grade AI engineering means building models and systems so they operate reliably in regulated production environments: deterministic interfaces, traceable decision paths, scalable data pipelines and security at both network and model level. It's not enough to prototype an idea — it must be transitioned into continuous operation.
Market analysis & local dynamics
In Cologne traditional manufacturing and chemical companies meet large trading players and a pronounced service landscape. This heterogeneity offers concrete opportunities: data from production, quality assurance and logistics can be combined to create predictive maintenance, process optimization and optimized supply chains. At the same time many companies face legacy systems — integration remains the biggest technical hurdle.
Regulation and auditors in the chemical and pharmaceutical industries drive transparency and traceability. AI solutions therefore must provide documented data provenance, model versioning and reproducibility of results. In Cologne many companies also work with external research partners and universities — this facilitates pilots, but increases the requirements for data sovereignty.
Concrete use cases for Cologne
1) Safety Copilots: LLM-based assistants that combine safety data sheets, operating manuals and real-time sensor values to support operators in case of deviations. These copilots are not a replacement for safety processes but a layer that reduces reaction times and minimizes errors through clear action recommendations.
2) Lab process documentation & knowledge search: Automated capture and semantic indexing of experiment data, test protocols and SOPs. With enterprise knowledge systems (Postgres + pgvector) teams can find relevant experiment series, validation documents or approval files in seconds — a major productivity lever in pharma R&D and QA.
3) Predictive maintenance & process optimization: Data pipelines that combine machine data, process variables and quality metrics enable predictions about failures and quality drops. These use cases reduce downtime and scrap in plants along the Rhine.
Engineering approach & architectural principles
We recommend a modular architecture: clear separation of data ingestion, feature engineering, models and serving. For sensitive environments, self-hosted infrastructure (e.g. Hetzner, MinIO, Traefik) is often the best option because it enables full control over data and models. Hybrid models are also feasible: keep the sensitive core in your own data center, non-sensitive components in certified clouds.
Model-agnostic solutions are crucial: depending on the use case, OpenAI models, Groq, Anthropic or locally hosted LLMs may be appropriate. For many chemical & pharma applications we recommend strict evaluation and red-teaming steps: robustness tests, prompt-fuzzing and adversarial monitoring before a model goes into production.
Data pipelines & integration
Typical data sources are Manufacturing Execution Systems (MES), Laboratory Information Management Systems (LIMS), historical SCADA data and document management systems. A reliable ETL system that cleans, versions and semantically enriches data is the foundation for any robust model. Dashboards and forecasting tools must be integrated into existing reporting stacks, not run alongside them.
A common mistake is neglecting data quality: models reflect the quality of their input data. Therefore invest early in data instrumentation — schema checks, drift monitoring and automated data validation — to ensure long-term stability.
Security, compliance & governance
Security is a top priority in the chemical and pharmaceutical industries. Access controls, audit logs, encryption in transit and at rest, and governance processes for model and access versions are indispensable. In many cases a no-RAG approach or private chatbots without external knowledge retrieval make sense to prevent leaks of confidential formulations or patents.
We implement role-based access, data masking and endpoint protection. Additionally, a governance board is recommended to approve changes to models, data and integrations — especially for validation-bound processes in the pharma sector.
Implementation, rollout & change management
A successful rollout follows iterative pilots: proof-of-concept, pilot with live data, scaling. It is crucial that operational teams are involved from the start — lab staff, shift leaders and QA personnel must understand the new tools and build trust. Training, co-creation workshops and a clear feedback loop are part of our Co-Preneur approach.
Measurable KPIs should be defined in parallel: lead times, scrap rates, MTBF, time to decision. Only with clear metrics can ROI be made transparent over time.
ROI, timeline & team
A typical AI PoC with us takes a few days to weeks; a production-ready system usually requires 3–9 months, depending on data maturity and integration effort. The biggest levers are realized by companies that bring domain experts, data scientists, DevOps engineers and QA specialists into the project team.
ROI arises not only through automation but also through risk reduction: faster incident response, fewer regulatory errors and higher confidence in production decisions. In many cases an AI solution pays off within 12–24 months when scrap and downtime are taken into account.
Common pitfalls & how to avoid them
The most common mistakes are: overly large scope jumps, poor data quality, lack of stakeholder involvement and underestimating compliance requirements. A clear roadmap, strict metrics and an iterative delivery model remedy these issues.
Technically we avoid vendor lock-in through modular interfaces and model-agnostic deployments. Organizationally we establish change journeys that include training, process documentation and a sustainable operating model — so the solution does not lose relevance after launch.

Key industries in Cologne
Cologne has long been a hub between industry, trade and media. The city on the Rhine has industrial roots that solidified in the 20th century with chemical production sites and mechanical engineering companies. This traditional industry now meets a lively services and media landscape — an environment that favors interdisciplinary AI solutions.
The chemical sector in and around Cologne historically benefited from good transport connections and a dense supplier structure. From this emerged an ecosystem where process digitization and safety processes are central topics. For AI engineering this means: solutions must be robust, auditable and integration-friendly.
Pharma and life-science activities in North Rhine-Westphalia, with many research institutions and contract researchers, create a need for intelligent document search, automated lab process capture and secure knowledge systems. In Cologne research and industry are often combined, enabling translational projects to be transferred to practice quickly.
The process industry along the Rhine includes chemical, food and supplier companies that rely on efficiency and resilience. Predictive maintenance, quality forecasting and process stabilization are classic AI application fields here with direct economic benefit.
At the same time Cologne is an important location for trade and logistics: companies like the Rewe Group need intelligent supply-chain solutions that integrate well with chemical supply chains and hazardous goods processes. This link between trade and production opens up cross-sector AI applications.
The insurance and service sector in Cologne, represented by companies like AXA, drives demand for risk and compliance applications. Insurers are often early adopters of AI in risk assessment — an advantage for chemical and pharma companies that want to model their operational risks.
Media and the creative industries complete the picture: companies like RTL are innovation engines for data-driven products, and this culture of rapid prototyping also promotes acceptance of new technologies in industry. A mix of conservative production and agile product development makes Cologne an exciting location for AI projects.

Frequently Asked Questions
A proof-of-concept (PoC) can be implemented very quickly for a well-defined use case: typically we deliver initial technical results within a few days to weeks. The key is precise scope definition: which data is available, which concrete outcome is being measured and which success criteria apply?
For lab projects we usually start with data ingestion and a rapid feasibility check of the models. If structured experiment data and documentation are available, a prototype that demonstrates semantic search, extraction of measurements or a simple assistance function can be built quickly.
The real time investment often comes afterwards: data collection over longer periods, quality assurance and integration work into LIMS or MES. These steps are necessary to turn a PoC into a reliable production system and to meet regulatory requirements.
For Cologne-specific projects we recommend that the core team of domain experts, data engineers and IT stakeholders be on site — we travel to Cologne regularly to iterate quickly together and get direct user feedback. This reduces friction and accelerates the transition to production.
Security in AI systems covers multiple layers: data security, model security, access control and operational monitoring. For the chemical and pharmaceutical industries there is the additional need that decisions must be explainable and auditable. This starts with encryption for data in transit and at rest and extends to audit logs that document every model prediction and version.
An important aspect is the separation of sensitive data: trade secrets, formulations and test protocols should remain in controlled environments. Self-hosted infrastructure (e.g. Hetzner combined with MinIO for object storage) allows full control over the data. For some clients we implement hybrid architectures where only less-critical parts run in certified clouds.
On the model level we recommend strict governance: versioning, access controls for model changes, red-team tests and monitoring for output drift. The ability to immediately take models offline if unexpected behaviors occur is also part of a responsible security strategy.
Finally, organizational security is important: roles, processes and incident playbooks. In Cologne many auditors and certifiers follow clear standards — close coordination with QA and compliance teams is therefore indispensable before systems go live.
Whether self-hosted is better than a cloud solution depends on many factors: data sensitivity, regulatory constraints, existing IT strategy and costs. In the chemical and pharmaceutical industries self-hosting is often attractive because it offers control over data, latencies and operator responsibilities.
Technically, a self-hosted infrastructure (e.g. with Hetzner, Coolify, MinIO, Traefik) allows full control over network, storage and security policies. Integration of edge components in production environments is also easier to implement. For some companies this is a must to meet environmental and data protection requirements.
Cloud providers, on the other hand, offer scalability, managed services and often better out-of-the-box ML tools. A hybrid approach combines the advantages of both worlds: sensitive data and core services on-premise, scalable training environments in the cloud when data can be anonymized or aggregated.
Our recommendation for Cologne companies is: evaluate based on data classification, resilience requirements and total cost of ownership. We help justify a decision technically and financially and implement the appropriate architecture.
Regulatory requirements often demand that decisions are traceable and documented. For AI systems this means: versioned models, traceable data pipelines, audit logs and explainable models or explanation mechanisms (XAI), where possible. These elements must be considered already in the architecture.
Practically, we build traceability pipes that link every prediction to a data snapshot, model version and input preprocessing. For pharma applications we additionally document validation processes and test data to provide reproducible test series as auditors expect.
For generative systems and LLMs we recommend output limitations, prompt logging and filtering mechanisms to avoid unwanted or unsafe responses. In many cases a no-RAG system is sensible so the model does not query uncontrolled external data sources.
Together with compliance teams we also develop standardized review processes that evaluate changes to models and data. This enables companies to meet regulatory requirements on an ongoing basis and to respond to inquiries from authorities in a structured way.
A successful AI project requires interdisciplinary teams: domain experts (chemical engineers, lab managers), data engineers, ML engineers, DevOps/platform engineers, security specialists and product owners. Additionally, change managers and trainers are essential to ensure the solution is adopted in day-to-day operations.
Domain experts ensure KPIs are correctly defined and models are interpreted sensibly. Data engineers provide stable ETL pipelines and data quality; ML engineers develop models and handle testing and monitoring. DevOps teams operate the infrastructure, automate deployments and ensure scalability.
In Cologne and NRW research collaborations with universities are often useful — they bring additional expertise but also requirements for IP and data access. We moderate such partnerships and ensure project objectives remain clear.
Reruption complements such teams as Co-Preneurs: we bring engineering capacity, project management and the experience to take projects into production — and we work on site in Cologne to enable fast iterations and smooth handovers.
ROI can best be captured with concrete KPIs: reduction in scrap, improved throughput times, lower downtime (MTBF), reduced testing effort and outsourced support costs. Monetary effects should always be measured with baselines (before/after) to show real savings.
For Safety Copilots, for example, reaction times and the number of safety-relevant incidents can be measured. In labs one can look at time to result, the number of repeated experiments or testing costs. All these metrics can be represented in dashboards and monitored continuously.
Another factor is reduced opportunity costs: faster time-to-market for products, fewer delays in approvals and lower liability risks. These indirect effects are often underestimated in classic ROI calculations but are decisive in regulated industries.
We create a measurement matrix together with clients, implement monitoring and deliver a transparent report that presents not only technical metrics but also economic impacts — making the value of AI projects in Cologne tangible for decision-makers.
