MVPs, platforms & business software
Production-ready MVPs, custom platforms, client portals and internal business software. We design the system, build the core flows and hand it over in a state your team can maintain and extend.

Senior engineering for MVPs, custom platforms, client portals, internal tools and lead-generation websites — for founders, growing teams and selected Mittelstand companies that need software they can run, own and extend.
Some projects begin with a 5-day Architecture Sprint. Others start directly with a focused website, portal, MVP or platform build. In every case, we define workflows, system logic, responsibilities and the delivery plan before implementation starts.
Start with the business problem. Each cluster connects to focused service pages for deeper scope, audits, migrations and ongoing support.
Production-ready MVPs, custom platforms, client portals and internal business software. We design the system, build the core flows and hand it over in a state your team can maintain and extend.
Backend systems, event flows and architecture decisions for products that need reliable foundations before traffic, data and integrations grow.
High-quality websites, landing systems and product interfaces where UX, SEO, CRM, analytics and engineering work as one system. Modern Next.js / React stack, conversion-aware from the first sprint.
Cloud infrastructure, deployment pipelines, observability and resilience for teams that need delivery and operations to scale together. One engineering discipline, not five vendors.
CRM logic and operational integrations that turn disconnected tools into systems people actually use. AI features and data engineering are separate specialised services below.
Each scenario maps to one of the five clusters above — every link stays inside the architecture, no orphans.
The current site doesn't convert, doesn't rank, or doesn't connect to the actual sales process.
Customers, partners or internal teams need a secure, role-based interface — not another shared spreadsheet.
Operations have outgrown Excel, Notion, Airtable and disconnected tools. Errors and lost context are getting expensive.
The product works, but every change breaks something else.
Traffic, data or users have grown, and the system needs performance, monitoring and cleaner infrastructure.
The product handles customer data, permissions or integrations, and the technical setup needs to be easier to explain, review and maintain.
Decisions are made on dashboards nobody fully believes.
Rewrites slow the roadmap and kill momentum.
These eight services address narrower buyer intents — migrations, performance, API design, AI features, IDP work. Each lives on its own page so it can collect its own SEO traffic, but they're visually separated from the primary offer above: you don't need a full build, you need a precise intervention or a specialised engineering discipline.
Structured ongoing development and operational support for live platforms with real users and multiple stakeholders. Senior engineers, not ticket queues.
SEO migrations, platform modernisation and technical relaunches with redirect, monitoring and risk-management work. Phased delivery while operations stay live.
React performance, Core Web Vitals and system-level scalability work. Backed by measurement, not vibes.
Clear API contracts, versioning, secure access and documentation — for internal, partner and public APIs your next senior hire can actually build on.
Next.js / React / TypeScript frontends for SaaS, dashboards, portals and internal tools — built around workflows and maintainability, not the launch screenshot.
Practical AI features inside platforms you already run — document parsing, RAG, smart search, workflow triage. Vendor-neutral, GDPR-aware, human review by design.
Data pipelines, reporting infrastructure and analytics that founder, sales lead and product manager all trust. Source of truth, not dashboard theatre.
B2B website redesign and migration: new structure, headless CMS, CRM-connected forms, URL mapping and redirect planning with a controlled relaunch.
We ship most projects across two main verticals. Three additional platform domains and the full industry detail live on the Industries page.

Pre-seed to Series A teams that need the production-ready foundation — before the product rewrites itself.
Explore B2B SaaS vertical
Phased migration for established German companies. Daily operations stay live while cleaner architecture comes online.
Explore Mittelstand verticalWe define workflows, data, permissions and system boundaries before development starts, so the first version can grow instead of becoming a throwaway build.
You work directly with the engineer designing your system. No opaque hand-offs, no outsourced execution, no account-management layer between you and the technical work.
Every engagement is built on the assumption your in-house team takes ownership eventually. Documentation, structure and naming are part of the deliverable.
Workflows, integrations and responsibilities are mapped first — sometimes through a 5-day Architecture Sprint, sometimes inside a focused build kickoff. No implementation begins on a fuzzy brief.
You can contact us for production-ready MVPs, custom web platforms, client portals, internal tools, lead-generation websites, CRM-connected systems, and modernisation of existing products or workflows.
No. We work with funded startups, founder-led companies, growing businesses and selected Mittelstand teams. The common pattern is not company size, but the need for custom software that supports real workflows, customers or operations.
Yes. We support established German companies with phased modernisation, internal tools, portals and operational software. The best fit is a practical, focused project where we can improve one workflow, system or product area at a time without forcing a full rewrite.
If the scope is unclear, start with a short architecture or product scoping sprint. We map the workflows, system logic, risks, integrations and delivery roadmap before committing to a full build.
Yes. An Architecture Sprint or a focused proof-of-concept can be the right first step before committing to a larger build. You validate architecture and scope without the full upfront investment.
Focused websites, lead systems and smaller business tools usually start around €5k–10k. Architecture sprints start from €3.5k. MVPs, portals and custom platforms typically range from €15k to €50k+, depending on scope, integrations and production requirements.
Yes. The project is built for your ownership: source code in your GitHub/GitLab organisation, documentation, deployment setup and handover are part of the delivery. No vendor lock-in, no black-box dependency.
We implement the technical foundations: EU hosting options, consent setup, access controls, data-flow documentation and handover. Final legal wording and compliance review should be handled by your legal or privacy advisor.
No — and no serious party can. We don't apply for grants or give tax advice on your behalf. For clients exploring Germany's R&D tax credit (Forschungszulage), we partner with Forschungsmittel.com, who handle the BSFZ application and tax-side coordination. We focus on building and documenting the R&D component the way the BSFZ expects. How it works →
Yes, when the website is part of a business system: SEO, lead generation, CRM, analytics, editorial workflows or campaign infrastructure. We are usually not the right fit for simple low-budget brochure sites or template customisation only.
Typical scope can include auth, user roles, database, primary product flows, admin panel, API layer, integrations, deployment, analytics, documentation and handover. The exact scope is fixed before development starts.
Yes. We build internal tools, admin panels, customer portals, partner portals, booking systems, operational dashboards and workflow platforms for companies that want to move beyond spreadsheets, Notion, Airtable or disconnected tools.
Yes, when it creates practical value. AI can be added for document processing, summaries, smart search, internal assistants, workflow support or lead qualification. We do not treat AI as a separate trend; it is an optional layer inside useful business software.
Yes. We can support the product after launch through retainers or an engineering partnership covering maintenance, improvements, infrastructure, monitoring, documentation and scaling decisions.
From product idea to production system — we help you define, build and hand over software your team can run.
