# Think big. Start Klein. klein.business advises and supports companies from IT strategy, architecture, software engineering and AI to modernising existing systems and running them reliably. With enterprise project experience and compliance built in from the start. - Founded: 2017 - Headquarters: Oberschleißheim near Munich, Germany - Focus: IT strategy, architecture, software & AI, modernisation, DevOps, quality - Industries: Automotive, telecommunications, financial services, private equity, software, mid-sized businesses - Partner: Das Digitale Momentum - Project languages: German, English ## Selected references - Premium car manufacturer (DAX company) - Reinsurer (DAX company) - Insurance group (DAX company) - Automotive group (DAX company) - Social media platform (USA) - Mobile network operator (Germany) - Telecommunications group (DAX company) ## klein.business in numbers - **2017** founded – working for enterprises and mid-sized companies ever since - **5** DAX companies among our references - **8** industries, from automotive to private equity - **1** team for the whole way: strategy, delivery, operations ## Consulting, engineering and operations from a single source We combine consulting with delivery accountability – and stay until it runs. ### 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. ## 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. ## Experience in regulated, business-critical environments - **Automotive:** Cloud architecture, platforms and software development for international vehicle manufacturers. - **Telecommunications:** Platform architecture, DevOps, release management and programme management for network operators. - **Banking:** Cloud migration and core system modernisation under supervisory requirements. - **Insurance:** Replacing legacy policy systems and securely integrating new digital services. - **Private equity:** Technical due diligence and modernising and scaling the IT of portfolio companies. - **Software companies:** Architecture, DevOps and platform engineering for products that scale. - **Media & platforms:** DevOps and stable operations for high-traffic digital platforms. - **Mid-sized businesses:** Digitising processes and business models – step by step and cost-effectively. ## Four phases with clear deliverables 1. **Analysis:** System landscape, dependencies and regulatory frame as a solid baseline. 2. **Design:** Target picture, architecture and delivery plan with milestones, risks and compliance controls. 3. **Delivery:** Iterative, automated and measurable – together with your teams. 4. **Handover:** Stable operations, complete documentation and enabled teams. ## Our own products, built together with partners Alongside consulting, we develop and operate our own software products together with partner companies – for identity and billing, property management, scheduling, hospitality and data research, as well as open-source tools for AI agents. That means we carry responsibility for architecture, operations and evolution ourselves and bring this experience straight into client projects. - Partner: [Das Digitale Momentum (DDM)](https://www.das-digitale-momentum.de/) ## Talk to us Briefly describe your initiative.
