Innovators at these companies trust us
The local challenge
Medical technology and healthcare device companies in Cologne are under pressure: stricter regulation, complex documentation requirements and the expectation of faster product cycles. Many AI ideas stall at the PoC stage — without robust engineering standards the last mile to production is missing.
Why we have the local expertise
Reruption is headquartered in Stuttgart but regularly travels to Cologne and works on-site with clients in North Rhine-Westphalia. We know the regional economy on the Rhine: the mix of media, chemicals, insurance and industry shapes how projects are prioritized, approved and executed here.
Our teams bring technical depth combined with operational ownership: we embed ourselves like co-founders, take P&L responsibility for delivered solutions and drive production-readiness with clear metrics. In Cologne we work directly with engineering, compliance and product teams to realistically map clinical workflows and address regulatory requirements early.
Practically this means: we build not just prototypes but also the data pipelines, deployment strategies and self‑hosted infrastructures (e.g., on Hetzner with MinIO, Traefik and Coolify) that keep medical devices stable in the field. Our experience allows us to align technical decisions with approval and operational requirements.
Our references
For AI-driven user interaction and automation we implemented an NLP-based recruiting chatbot with Mercedes Benz that enables 24/7 candidate communication and automated pre-qualification — experience that transfers directly to clinical communication and patient triage. For regulatory documentation and research projects our collaboration with FMG provides valuable expertise in building AI-powered document search and analysis systems that reliably prepare compliance-relevant information.
In the hardware and manufacturing domain, projects like Eberspächer (noise reduction) and work for STIHL (product and training tools) support our understanding of quality processes, sensor data and product simulation pipelines — important building blocks for MedTech device validation and test automation. On the product side, technology engagements with BOSCH, AMERIA and TDK provide insight into embedded and HMI requirements that are relevant for medical devices.

AI engineering for medical technology & healthcare devices in Cologne: a comprehensive guide
The medical technology sector today demands more than smart prototypes: it requires scalable, secure and auditable AI systems that improve clinical processes, meet regulatory requirements and integrate seamlessly into existing IT landscapes. In Cologne, at the intersection of industry, chemicals and media, a special ecosystem emerges: short innovation cycles on one side and strict compliance requirements on the other. This balancing act is the central challenge for any AI engineering project.
Market analysis and regional specifics
Cologne and the greater Rhine-Ruhr region feature a heterogeneous corporate structure: global industrial corporations, mid-sized suppliers and dynamic startups. For medical technology this means: supply chains are complex, partner networks are diverse and regulatory reviewers are often distributed across different federal states. Companies in Cologne benefit from a strong service and media landscape that is relevant for digital communication and patient experience solutions.
Proximity to large industries such as chemicals and automotive also creates opportunities for cross-industry innovation: validation methods, sensor technologies and production processes can be adapted. At the same time, the local culture demands pragmatic solutions: proofs must demonstrate tangible benefits quickly before larger investments are approved.
Concrete use cases for medical technology
Several AI use cases are immediately relevant for MedTech companies: documentation copilots for automated creation, classification and revision of technical documents; clinical workflow assistants that support nursing and treatment processes; automated regulatory alignment tools that review approval documents; and secure, private AI infrastructures for data-sensitive functions.
A documentation copilot can, for example, detect new versioning requirements, automatically generate change logs and suggest inputs for risk assessments. Clinical workflow assistants can support clinical staff with routine decisions without taking responsibility — they provide recommendation chains, link to relevant SOPs and log decisions for audits.
Technical architecture and modules
Production-ready AI engineering requires a modular architecture: data layer (ETL, data warehouse), feature and model layer (vector DBs like Postgres + pgvector, models, fine-tuning), orchestration (agents, multi-step workflows) and serving and observability layers. Our service modules include, among others, custom LLM applications, internal copilots & agents, API/backend development (OpenAI/Groq/Anthropic integrations), private chatbots (model-agnostic), data pipelines & analytics, programmatic content engines, self-hosted AI infrastructure and enterprise knowledge systems.
For MedTech, self-hosted options are particularly important: local data sovereignty, traceable logs and controlled access paths are prerequisites for certifications and audits. We recommend hybrid architectures, where sensitive inference work remains on-premises or in trusted datacenters (e.g., Hetzner), while less critical components can run in certified cloud environments.
Security and compliance requirements
Regulatory questions run through every project: GDPR-compliant data processing, Medical Device Regulation (MDR), ISO standards and clinical trial requirements. AI engineering must provide audit trails, revision safety, model versioning and reproducible training pipelines. Validation plans for models are also necessary, containing performance metrics, test sets and monitoring specifications.
Technically this means: strict access controls, encryption at rest and in transit, role-based access concepts and logging at the data, model and API levels. For regulatory reviews we provide the necessary documentation: technical specifications, test protocols, risk analyses and release notes that reviewers can follow.
Implementation approach and roadmap
Our typical path: first a focused PoC (€9,900 AI PoC offering) that demonstrates technical feasibility, data availability and initial performance metrics. In parallel we define metrics for clinical relevance, cost per run and robustness. After a successful PoC follows a minimal live product with extended testing, monitoring and a clear production architecture.
Timing expectations: PoC in days to weeks, production MVP in 2–4 months depending on data integration and regulatory requirements. Full production and validation projects can take 6–12 months, including audit readiness and organizational integration.
ROI, economics and success criteria
The ROI for MedTech AI projects often derives from less obvious levers: reduced time for document review, lower defect rates in manufacturing, faster market entry through automated approval documents and relieved clinical staff. Success factors are early stakeholder validation, measurable metrics and a roadmap that includes compliance milestones.
It is important to combine technical KPIs (latency, throughput, error rate) and clinical KPIs (e.g., reduction of administrative errors, shortened documentation times). Only then can an investment be justified against internal priorities.
Technology stack and integration issues
We work model-agnostically: from OpenAI APIs to Anthropic to specialized on-prem models. For vector-based search we recommend Postgres + pgvector; for storage MinIO; for deployment Traefik and Coolify; for infrastructure Hetzner or customer-owned datacenters. API design, observability (tracing, metrics) and CI/CD are integral parts of every solution.
Integration with existing systems (PACS, EMR, MES, ERP) is often the biggest technical hurdle. We rely on clear API contracts, event-driven architectures and abstracted adapters so that core systems do not need modification and data sovereignty is preserved.
Team, skills and change management
Successful AI engineering requires interdisciplinary teams: data engineers, MLOps/DevOps, backend developers, compliance experts, product managers and clinical specialists. In Cologne it makes sense to involve local partners and universities to leverage domain knowledge and recruitment pools.
Change management is not optional: training, clear operating processes, playbooks for model drift and escalation paths are necessary for the technology to be adopted in daily operations. We support client teams from introduction to handover and provide enablement programs.
Common pitfalls and how to avoid them
Common mistakes are: choosing expensive models too early, poor data quality, incomplete validation plans and insufficient involvement of compliance. We recommend iterative rollouts, comprehensive test datasets, documented validation workflows and a conservative security architecture.
A pragmatic piece of advice: start with a clearly limited use case, measure a concrete benefit, and then scale systematically. This minimizes risk and builds trust with regulators and users.
Conclusion
Cologne offers a productive mix of industry, research and services — ideal conditions for MedTech innovation. But to move AI from the lab into the clinic requires solid engineering, compliance competence and local implementation experience. Reruption brings these elements together: we travel to Cologne regularly, work on-site with teams and deliver production-ready AI solutions that are auditable, secure and clinically relevant.

Frequently Asked Questions
A focused AI PoC can typically deliver initial technical results in medical technology within a few days to a few weeks. The goal of a PoC is not full regulatory readiness, but to answer core questions: Is the data quality sufficient? Can a model be trained to reach the desired metrics? Are the integration points with existing systems available?
In Cologne we make sure to plan for local conditions: who are the decision-makers? Which data protection and operational requirements apply? We align PoC scope and success criteria on-site with the responsible teams so that results are directly usable.
Practically, a PoC starts with use-case definition, data checks and a minimal architecture. We deliver a working prototype, performance metrics and a production roadmap — so decision processes can be accelerated and the project does not remain stuck in the concept phase.
Important: a quick PoC proves technical feasibility, but regulatory and organizational aspects require more time. After the PoC comes the validation and production phase, where audits, documentation and more extensive tests are carried out.
Security requirements are a central point for MedTech AI systems: GDPR-compliant data processing, secure authentication, access control and encryption are the minimum. In addition, MDR and relevant standards require traceability, revision safety and documented validation of software components.
Technically this means: encryption in transit and at rest, role-based authorization, audit logs at the data and model level, and clear procedures for incident response. Training and test data should also be versioned and model changes traceable to meet regulatory requirements.
For locally sensitive data we recommend self-hosted or hybrid architectures that ensure data sovereignty. Tools like MinIO for storage and internal vector databases (Postgres + pgvector) enable controlled processes, while gateways and API security layers secure access.
Finally, security-by-design is indispensable: security requirements must be integrated from the start into architecture, development processes and tests. Reruption supports the creation of the technical documentation auditors and reviewers expect.
Integration into clinical workflows starts with a deep understanding of the processes: what data is generated, who makes decisions, and which interfaces exist to EMR/PACS/MES? Only by understanding these processes can you design meaningful automations and assistive functions that support staff rather than burden them.
We recommend a phased approach: first introduce assistive functions in non-critical areas (e.g., documentation, preparation), then gradually move into clinical decision support. User involvement in design and testing phases is crucial to ensure acceptance.
Technically, we work with standardized interfaces and adaptive adapters so that existing systems do not need major modification. Event-based communication and API gateways allow loose coupling, while observability ensures performance and errors become visible quickly.
For most projects, a governance board is also sensible to clarify clinical, data protection and technical questions. This keeps responsibility clearly defined and ensures the controlled introduction of assistive systems.
Self-hosted infrastructure plays a major role because it provides data sovereignty, low latency and controllable security measures — all criteria important for medical devices and clinical applications. For many manufacturers it is an advantage to perform sensitive inference work locally to better control regulatory and data protection requirements.
Technically this means using solutions like Hetzner or company-owned datacenters, with components such as MinIO for storage, Traefik for routing and Coolify for deployment orchestration. What matters is a standardized, reproducible infrastructure that is documented for audits.
Self-hosting has trade-offs: higher operating costs and responsibility for security and backups. Therefore we recommend hybrid concepts where non-critical loads run in certified cloud environments while sensitive data and models remain local.
For firms in Cologne, self-hosting is often the practical middle ground: regional datacenters and service providers offer good connectivity and compliance support while local IT teams retain control. Reruption supports setup, hardening and handover to operational teams.
Reruption is based in Stuttgart, but we travel regularly to Cologne and work on-site with clients. Practically this means: at the start of a project we are on-site for workshops, stakeholder interviews and technical scoping to understand requirements precisely and build trust.
During implementation we combine on-site work with remote sprints. Important milestones — PoC demos, architecture reviews and acceptance workshops — are often conducted in person to enable quick decisions and increase acceptance among local stakeholders.
Our co-preneur approach means we take responsibility: we work within your teams, deliver prototypes and production-ready components, and ensure a smooth handover and operation. After go-live we provide enablement, training and supported onboarding.
This hybrid collaboration has proven particularly effective in regulated environments because it ensures the necessary proximity to domain experts while allowing fast iterations.
Costs and timelines vary greatly depending on scope. A technical PoC with verifiable results can be realized with our standard offering (€9,900). This PoC tests feasibility, performance and delivers a production roadmap. Costs for a production MVP depend on integration depth, validation requirements and infrastructure and often fall into the mid six-figure range.
In terms of time, an iterative approach is realistic: PoC in days to a few weeks; MVP in 2–4 months; full production including validation and audit readiness 6–12 months. Clinical studies or extensive regulatory processes can add additional months.
Key cost drivers are data collection and cleaning, infrastructure (especially self-hosted solutions), testing/validation and the creation of regulatory documentation. Focused scope management and early involvement of compliance can reduce these costs.
Our advice: budget for iterative learning, set milestones with clear deliverables and choose a partner who brings both engineering and compliance expertise to avoid surprises.
