Lean MVP in 4 weeks, Standard MVP in 6–8 weeks.
Free first assessment within one business day · Optional funding check
Four product types we ship with full architecture, backend, admin and delivery — from Sprint Zero to handover to your team.
01

Multi-tenant architecture, subscription logic, onboarding, role-based dashboards, audit trails and GDPR-compliant EU hosting.
Multi-tenant from day one

03
Marketplaces
Two-sided platforms with listings, search, transactions, reviews and an admin layer strong enough to actually run operations.
Listings & search
Transactions & escrow
Provider onboarding
04
Internal tools

Workflow engines
ETL & data pipelines
Operations dashboards
Is this a fit for your project? · 02
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 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 by default
Even your first B2B product should isolate tenants cleanly. Retrofitting it costs months. Building it in costs days.
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
Pipelines, logs, monitoring and audit trails belong in the MVP. Not when 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.

One dedicated contact. From kickoff to handover.
At H-Studio you don't talk to three account managers and an offshore team you never get to meet. You have one direct contact — Patrick — who follows your project from the first architecture sketch to production deploy, aligns every technical decision with our senior engineers, and makes sure nothing gets lost in the telephone game.
Behind every project there's a senior engineer as tech lead who writes the code and owns the architecture. Patrick makes sure you understand what's happening, that reviews land on time and that your requirements end up cleanly in the backlog — without you having to play engineering manager.
We're small and selective. We take a maximum of three new platform projects per quarter — if your idea is a fit, we'll talk about what we'd actually build and why.

Founder notes · 06
What founders say about working with us.
”
They quickly understood my problem, developed solutions, and delivered extremely fast. I'm very satisfied. It seems like they work around the clock at H-Studio, that's how fast they are.

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.
Dr. Houman HémmatGoogle ★

”
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 and data-model complexity. We give you a binding date and fixed price before phase 2 starts.
What does an MVP actually cost?+
Architecture Sprint from €2,500. Lean MVP for fast market tests from €12,000 in 4 weeks. Standard MVP from €18,000 in 6–8 weeks. Custom Platform with complex multi-tenant or marketplace logic from €25,000. On request we'll check with you whether current digitalisation or innovation programs match your company profile.
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 binding fixed price 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.
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.
How do you help with funding?+
Depending on location, company profile and project goal, digitalisation or innovation programs (e.g. via KfW or regional development banks) can be relevant. On request, we prepare a technical project description that you can use in a funding application. We can't guarantee funding approval — programs, conditions and availability change regularly. The actual application is filed by your company or a specialised funding consultant.
Where are you based and which markets do you serve?+
Studio in Berlin. We deliver primarily for DACH and the EU, with GDPR-compliant EU hosting setups. English is project language, German is standard for DACH projects.
