# Services We combine consulting with delivery accountability – and stay until it runs. Our services fall into three fields; in projects we combine them as your initiative requires. ## Strategy & governance - IT strategy & due diligence: Target pictures, technology decisions and technical due diligence – including for private equity investors and their portfolio companies. - Project & programme management: Steering complex initiatives between business, IT and service providers – including PMO and release management. - Compliance & data protection: GDPR, Schrems II, Confidential Computing and German web compliance (DDG, TDDDG, BFSG) – built into the technology, not just documented. - Digital presence, SEO & GEO: Websites and web platforms, technical SEO audits and visibility in AI-powered search. ## Architecture & engineering - Cloud & solution architecture: Target architectures, multi-tenant SaaS, API platforms and identity (OAuth 2.0, OpenID Connect) – scalable and maintainable. - Software & product development: Web, desktop and native apps as well as SaaS products – from the first release to operations, also together with partners. - AI & automation: AI agents, MCP servers and LLM integration – securely embedded in existing systems with guardrails. - Data & integration: Data platforms with Databricks, Spark and Kafka, event-driven integrations, reporting, web crawling and data enrichment. ## Modernisation & operations - Legacy & mainframe modernisation: Analysing, reconstructing and gradually replacing COBOL and PL/I estates – without putting operations at risk. - Platform engineering & DevOps: GitOps deployments, infrastructure as code, observability and FinOps for dependable releases and stable operations. - Quality assurance & testing: Test strategy and test automation for UIs, APIs and load scenarios – up to safeguarding large-scale migrations. - IT security & audits: Authorised security audits, security posture scanning and SIEM integration for platforms and websites. ## Four phases with clear deliverables - Phase 1 – Analysis: System landscape, dependencies and regulatory frame as a solid baseline. - Phase 2 – Design: Target picture, architecture and delivery plan with milestones, risks and compliance controls. - Phase 3 – Delivery: Iterative, automated and measurable – together with your teams. - Phase 4 – Handover: Stable operations, complete documentation and enabled teams. ## Compliance is part of the architecture – not the sign-off. When sensitive data leaves your own data centre, architecture decides whether a project holds up to regulators. That is why we anchor the requirements from the start. - Confidential Computing: Data stays protected even while it is processed, through hardware-based trusted execution environments. - Schrems II: Sound concepts for international data transfers and the compliant use of hyperscalers. - GDPR: Privacy by design and by default – demonstrable in architecture, processes and operations. ## Frequently asked questions ### Do you also deliver, or only advise? Both. We combine consulting with delivery accountability: from analysis through architecture and engineering to stable operations and the handover to your teams. ### How does a collaboration start? With a short [request](https://www.klein.business/en/contact/). We reply within two working days with a proposal for a no-obligation first conversation. Last updated: 2026-10-18 --- Source:
