Production-ready MVP software for founders and teams building SaaS products, customer portals, marketplaces or internal tools — with real backend logic, admin workflows, deployment and clean technical handover.
Fixed scope before buildFixed price per phaseYour code, your rights
Products with real logic. Not just a clickable prototype.
Four MVP and platform types we ship with backend, admin, data model, integrations and clean handover — so the first version doesn't become a rewrite project.
01
B2B SaaS products
Multi-tenant architecture, subscription logic, onboarding, role-based dashboards, audit trails — with EU hosting options and GDPR-aware setup.
Multi-tenant when neededStripe / Paddle billingAdmin console
02
Customer portals
Self-service areas for your customers — onboarding, documents, requests, status, roles and permissions. Clean integration into your existing systems.
Built for product systems with backend, data and admin.
This sprint is for teams building more than a static website: SaaS products, customer portals, marketplaces, internal tools and workflow platforms with roles, data, integrations and operational logic.
Good fit when
You need a production-ready first version, not just a visual prototype.
Backend, admin, permissions, workflows or integrations are part of the scope.
The product should be extendable after launch.
Documentation, ownership and handover matter from day one.
Still early?
We can help you decide whether the right next step is an Architecture Sprint, a lean MVP, a smaller proof of concept or a separate Next.js website / lead-system track.
Why architecture-first · 03
Most MVPs don't fail in the market. They fail in their own codebase.
The funnel works, the first customers arrive, investors get curious — and suddenly the codebase can't be extended anymore. That's exactly what we help prevent with five architecture principles.
01
Data model first
Before a single feature is built, we map workflows, roles and data flows — against late "we have to redo everything" moments.
02
Multi-tenant where needed
For B2B products with multiple customers or organisations, tenant isolation should be planned early. Retrofitting it later can be expensive; designing for it early usually keeps the foundation cleaner.
03
Domain-driven backend
Clear modules instead of spaghetti. New features can be added precisely without breaking the next one over.
04
CI/CD & observability
For production-facing MVPs, deployment pipelines, logs, monitoring and basic auditability should be planned from the start — not after a customer calls and something is broken.
05
Handover docs included
Your team takes over with ADRs, setup guides and an architecture briefing. No lock-in, no knowledge vacuum.
Packages & pricing · 04
Four clear starting points. Fixed scope before build. No vague hourly commitment.
You know what each phase is intended to deliver before it starts. Architecture Sprint as a small entry, Lean MVP as a fast market test, Standard MVP for real product maturity, Custom Platform for complex builds.

Founder notes · 06
What founders say about working with us.
”
Working with H-Studio was straightforward, reliable, and genuinely pleasant.
I worked with H-Studio to bring order to the internal processes of my dental clinic. They took the time to deeply understand how the clinic actually works, analysed existing processes, and built a clear, logical structure across our internal systems and workflows. The clinic now operates much more smoothly and operational pressure has decreased.

Working with H-Studio was valuable because they approached the product as a system, not just as a website or interface. They quickly understood the challenges of a data-heavy platform environment and were able to discuss architecture, user flows, integrations, and long-term maintainability with clarity.

Client testimonials reflect individual experiences and project scopes. Results and timelines may vary depending on requirements and context.
Architecture Sprint: ~1–2 weeks. Subsequent build: typically 4–10 weeks, depending on scope, integrations and data-model complexity. Before phase 2 starts you receive a written proposal with scope, target timeline and a fixed-price phase estimate; final dates depend on feedback cycles and required content/access.
What does an MVP actually cost?+
Indicative starting prices for business clients: Architecture Sprint from €2,500. Lean MVP from €12,000, designed for ~4 weeks. Standard MVP from €18,000, designed for ~6–8 weeks. Custom Platform with complex multi-tenant or marketplace logic from €25,000. Final scope, timeline and fixed-price proposal depend on requirements, integrations and feedback cycles; VAT may apply where applicable.
What exactly is the Architecture Sprint?+
A paid pre-phase where we model your project — workflows, roles, data model, tech stack, API contract, backend skeleton — and give you a fixed-price phase proposal for the build. If you continue with someone else afterwards, the architecture is still yours.
Can we start from an existing tech stack?+
Yes, if it makes sense. We work primarily with Next.js, React, Node and PostgreSQL plus Sanity or Strapi as headless CMS — and we're also productive with Python, Supabase, Vercel, AWS and Hetzner. For larger enterprise platforms we can also bring in Java/Spring on the backend. We sit down beforehand and check whether your stack actually carries the requirements.
What happens after MVP launch?+
Three options: your internal team takes over (with our docs and a handover briefing), we stay involved as a support retainer, or we build phase 2 as the next engagement. No lock-in contracts.
Can the build support an R&D tax credit application (Forschungszulage)?+
Sometimes — it depends on whether the work contains technical uncertainty in the BSFZ sense. We don't file or advise on the application ourselves; for clients exploring it we work with a specialised partner and document the R&D component the way the BSFZ expects. Details →
Do you also build marketing websites?+
No. For marketing sites and single funnels there are better and cheaper studios. We build products with backend, data and logic.
Can your scope document support internal approval or investor discussions?+
Yes — the Architecture Sprint produces a written scope document with system map, risks, timeline and a fixed-price build proposal. It is intended to help internal stakeholders or investors review the project clearly. We do not act as a funding advisor and do not guarantee any funding outcome.
Do you build GDPR-aware systems?+
We implement the technical foundations: EU hosting options, consent setup, data minimisation, access controls and logging where needed. Final legal wording and compliance review should be handled by your legal or privacy advisor.
Are the package prices final?+
Listed prices are starting points for business clients. Final scope, timeline and fixed-price proposal depend on requirements, integrations, content, access and feedback cycles. VAT may apply where applicable.
Where are you based and which markets do you serve?+
Studio in Berlin. We deliver primarily for DACH and the EU, with GDPR-aware EU hosting setup options. English is project language, German is standard for DACH projects.
