What we do

Four disciplines, one accountable partner.

  • Terraform & GitOps
  • Observability & SRE

AI & Data

From data foundations to production AI, we integrate models and analytics that create measurable leverage.

  • LLM & RAG integration
  • Data pipelines & warehousing
  • Decision dashboards

Cybersecurity

Threat detection, incident response and zero-trust architecture that keep your systems resilient and your customers confident.

  • Threat detection & response
  • Incident response & recovery

EU-Trusted Platforms

Sovereign, compliant platforms with European data residency, built for organisations that cannot compromise on trust.

  • EU data residency
  • Sovereign cloud
  • Digital compliance (DSA · NIS2)

We do not just build, we enable.

So that sovereignty is more than a promise, we hand over your system together with the knowledge to run it. Through workshops and training, we bring your team to the level that independent operation requires.

  • Hands-on workshops

    Practical sessions on cloud, AI and security, tailored to your stack and your goals.

  • Architecture & code reviews

    Joint reviews with your team that build knowledge rather than just deliver findings.

  • Onboarding for self-operation

    Structured handover and documentation so your team runs systems on its own.

A delivery model built on clarity and ownership.

No black boxes, no endless decks. We move from discovery to production in focused increments, with senior people accountable at every step.

German financial services provider Finance

Zero-Trust Security Architecture for a German Financial Services Provider

Design and rollout of a zero-trust security architecture on EU-sovereign infrastructure - BSI C5-compliant, fully auditable, and without a single workload leaving European jurisdiction.

External audit passed without findings in the first attempt. Lateral-movement risk reduced to near zero through segmentation, privileged access now fully attributable to individuals, and 100% of security-relevant logs stored under EU jurisdiction. The internal team operates the platform independently after a structured handover.

European manufacturing group Manufacturing

GDPR-Compliant AI Document Processing on European Infrastructure

A self-hosted LLM pipeline that extracts, classifies and routes 40,000 documents per month - running entirely on GPU infrastructure in German data centers, with no data ever touching a US API.

96% field-level extraction accuracy on German business documents, surpassing the managed-API baseline. Manual processing effort cut by 70%, full GDPR compliance confirmed by the DPO, and predictable costs: GPU capacity is reserved flat-rate instead of per-token billing.

Migration from a US Hyperscaler to a Sovereign EU Cloud

Lift-and-reshape of 120 workloads from AWS to OpenStack-based EU infrastructure - zero downtime, 30% lower run costs, and complete data residency for a public-sector supplier.

All 120 workloads migrated in seven months with zero unplanned downtime. Run costs down 30%, full data residency in German data centers certified to ISO 27001 and BSI C5, and the client qualifies for public-sector tenders again. The Terraform codebase makes the estate portable - sovereignty without a new lock-in.

FAQ

Questions, answered.

Typically within two to four weeks. After a short discovery call we send you a scoped proposal with a clear start date, so you know exactly when senior engineers join your team.

We are remote-first and work with clients across the EU. For kick-offs, workshops and key milestones we are happy to join you on-site, especially within the DACH region.

From focused two-week architecture reviews to multi-month platform builds. We structure every engagement in fixed-scope increments, so you keep control over budget and outcomes at each step.

Compliance is engineered in from the first line of architecture: EU data residency by default, documented processing, and designs aligned with GDPR, ISO 27001 and NIS2 requirements.

Defined scopes are priced fixed, embedded senior engineering is billed at transparent daily rates. You always receive a written estimate before any work begins.
