01 · How we start

Every engagement starts with clear scope.

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.

02 · Core services

Five engineering clusters.

Start with the business problem. Each cluster connects to focused service pages for deeper scope, audits, migrations and ongoing support.

03

Websites, portals & lead systems

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.

04

DevOps & infrastructure

Cloud infrastructure, deployment pipelines, observability and resilience for teams that need delivery and operations to scale together. One engineering discipline, not five vendors.

05

Integrations, data & practical AI

CRM logic and operational integrations that turn disconnected tools into systems people actually use. AI features and data engineering are separate specialised services below.

03 · Common scenarios

What teams come to us with.

Each scenario maps to one of the five clusters above — every link stays inside the architecture, no orphans.

04 · Specialised engineering services

Narrower engineering disciplines for existing systems.

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.

01 · Open service

Platform support & maintenance

Structured ongoing development and operational support for live platforms with real users and multiple stakeholders. Senior engineers, not ticket queues.

02 · Open service

SEO migration & relaunch

SEO migrations, platform modernisation and technical relaunches with redirect, monitoring and risk-management work. Phased delivery while operations stay live.

03 · Open service

React performance optimisation

React performance, Core Web Vitals and system-level scalability work. Backed by measurement, not vibes.

04 · Open service

API development

Clear API contracts, versioning, secure access and documentation — for internal, partner and public APIs your next senior hire can actually build on.

05 · Open service

Frontend development

Next.js / React / TypeScript frontends for SaaS, dashboards, portals and internal tools — built around workflows and maintainability, not the launch screenshot.

06 · Open service

AI automation

Practical AI features inside platforms you already run — document parsing, RAG, smart search, workflow triage. Vendor-neutral, GDPR-aware, human review by design.

07 · Open service

Data engineering & analytics

Data pipelines, reporting infrastructure and analytics that founder, sales lead and product manager all trust. Source of truth, not dashboard theatre.

08 · Open service

Website redesign services

B2B website redesign and migration: new structure, headless CMS, CRM-connected forms, URL mapping and redirect planning with a controlled relaunch.

05 · Where we ship

Two primary verticals, three platform domains.

We ship most projects across two main verticals. Three additional platform domains and the full industry detail live on the Industries page.

06 · Why H-Studio

What makes the engagement different.

  1. 01

    Built to reduce rewrite risk

    We define workflows, data, permissions and system boundaries before development starts, so the first version can grow instead of becoming a throwaway build.

  2. 02

    Named senior engineer from day one

    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.

  3. 03

    Code written to be handed over

    Every engagement is built on the assumption your in-house team takes ownership eventually. Documentation, structure and naming are part of the deliverable.

  4. 04

    Scope agreed before the build starts

    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.

FAQ · 011
  1. 01

    What type of project should I contact you for?

    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.

  2. 02

    Do you only work with funded startups?

    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.

  3. 03

    Do you work with German Mittelstand companies?

    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.

  4. 04

    What is the best starting point if I am not sure what I need?

    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.

  5. 05

    Can we start smaller than a full MVP?

    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.

  6. 06

    What budget should I expect?

    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.

  7. 07

    Do we own the code?

    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.

  8. 08

    Do you build GDPR-aware systems?

    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.

  9. 09

    Do you guarantee funding?

    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

  10. 10

    Do you build normal websites?

    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.

  11. 11

    What is included in an MVP or platform build?

    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.

  12. 12

    Do you also build internal tools and client portals?

    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.

  13. 13

    Can AI be included in a project?

    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.

  14. 14

    Do you offer ongoing support after launch?

    Yes. We can support the product after launch through retainers or an engineering partnership covering maintenance, improvements, infrastructure, monitoring, documentation and scaling decisions.
