Software that fits you – not the other way around.

We build tailored solutions, connect your existing systems and guide your IT projects from the first idea through to successful completion.

What We Do for You

From conception to delivery – we accompany your IT project from start to finish.

Code.

We work out what needs building – and build it.

Requirements Engineering

Most IT projects don't fail because of the technology – they fail because of unclear requirements. We help you avoid exactly that: from stakeholder analysis and user stories to a complete requirements document. Everyone knows what needs to be built – and your project starts on solid ground.

  • Requirements analysis
  • Use cases
  • User stories
  • Requirements Engineering
  • Functional specification
  • Agile requirements
  • Stakeholder management
  • Process analysis

Software Development

We build web and mobile applications that fit your processes exactly – no compromises, no off-the-shelf solutions. From the initial concept and thoughtful API design through to go-live, we're right there with you. The result: software that works today and scales with you tomorrow.

  • Software development
  • Custom software
  • Web App
  • Mobile App
  • Full-stack
  • API-design
  • Microservices

AI Integration

AI isn't a trend you can wait out – but it's no silver bullet either. The real value only comes when it's meaningfully embedded in your processes. We integrate LLM-based workflows, RAG systems and ML pipelines directly into your existing infrastructure – pragmatically implemented, built to scale and privacy-compliant, including on-premise.

  • AI integration
  • LLM
  • GPT
  • RAG
  • ML pipeline
  • AI workflow
  • Prompt engineering
  • AI agents

Integrate.

We connect what you already run with what comes next.

IT Consulting & Architecture

We analyse your IT landscape and develop a strategy that truly fits – from system architecture to a concrete implementation roadmap. So you make confident decisions and avoid costly missteps.

  • Architecture
  • IT Strategy
  • Digitalisation
  • Tech Stack
  • Technology Consulting
  • SME
  • Enterprise
  • Roadmap
  • Modernisation
  • Legacy Migration

System Integration

In most companies, IT has grown over the years – and so has the complexity. We bring order to the system: your applications, platforms and third-party software working seamlessly together. Reliably connected, securely operated and built to keep maintenance efforts manageable.

  • System integration
  • ERP integration
  • Middleware
  • EDI
  • API gateway
  • Data synchronization
  • Event-driven architecture

Cloud Solutions

Cloud isn't an end in itself – but done right, it's a real lever for your business. Whether you're migrating existing systems or building fresh in the cloud: we design and operate scalable architectures on AWS, Azure and GCP. Secure, reliable and cost-efficient – so the cloud genuinely pays off for you.

  • AWS
  • Azure
  • GCP
  • Kubernetes
  • Docker
  • Helm
  • Cloud migration
  • Cloud-native
  • Serverless
  • Infrastructure as Code
  • Containerization

Deliver.

We put software into production and keep it running securely.

DevOps & CI/CD

Manual deployments and slow release cycles hold your team back – and cost more than just time. We help you change that: with end-to-end CI/CD pipelines, automated tests and containerised deployments. The result is a team that ships faster, makes fewer mistakes and can focus on what actually matters.

  • DevOps
  • CI/CD
  • GitHub Actions
  • GitLab CI
  • Jenkins
  • Terraform
  • Blue-green deployment
  • Canary releases
  • Monitoring

IT Security & Pentesting

Attackers are patient and methodical – your security should be too. We actively search for vulnerabilities in your IT infrastructure before anyone else does: with penetration tests, structured vulnerability assessments and concrete recommendations that actually move you forward. No panic report – just a clear picture and a plan.

  • Penetration testing
  • Vulnerability scan
  • IT security
  • SAST
  • DAST
  • Security audit
  • OWASP
  • CVE
  • Application security
  • ISO 27001
  • GDPR

Maintenance & Support

IT problems don't respect business hours. To make sure they don't become real problems in the first place, we monitor your systems proactively, keep them up to date with patches and security updates, and respond quickly when something does go wrong. With clearly defined SLAs and open communication – so you always know what's going on.

  • 24/7 monitoring
  • SLA
  • Security patches
  • Incident management
  • Performance optimization
  • Log management
  • Managed services
