App development in Berlin
Updated: 2026-11
Many Berlin startups validate their idea with a prototype built in a no-code or AI tool. We take that prototype as the specification and rebuild the product on a maintainable stack: real authentication and permissions, tests, a clean data model, EU hosting and GDPR compliance, ready for paying customers and investor due diligence.
Your region: Berlin
Berlin’s startup scene moves fast, and prototypes built with AI app builders or no-code tools are now the normal starting point. They prove demand, but they rarely survive contact with real customers: permissions are missing, data models are improvised, and nobody can maintain the generated code.
We treat the prototype as a valuable specification rather than a codebase, and build a production version founders can own and extend. We work remotely from Zug, in English, with founders and early teams across Berlin.
How we deliver
Prototype as specification
We walk through the prototype with you and turn its screens and flows into a precise list of requirements before rebuilding.
Permissions in the database
Tenant separation is enforced with row-level security in Postgres, so a frontend bug cannot expose another customer’s data.
Due diligence in mind
Code, infrastructure and data protection documents are organised so that a technical due diligence finds answers quickly.

From AI or no-code prototype to a production web app
AI app builders and no-code tools produce convincing prototypes quickly, but rarely a foundation for operations. We analyse the prototype, take its flows, screens and learnings as a specification, and rebuild the application on Next.js and Supabase with proper permissions, tests and data protection.
App concept and scoping
Before an app is built, a concept answers the questions that decide budget and success: who uses it, for what, on which devices? Is a PWA enough or is a store app needed? Which data, which interfaces, which first scope? The result is a basis for binding quotes, from us or anyone else.
Fixed-price MVP development
Fixed-price MVP development delivers a clearly scoped, working product at a price defined up front — on a modern, EU-hosted stack. Not an open-ended hours bucket, but a defined scope with a clear result.

App development in Vienna
Vienna is home to international organisations, service companies and a growing tech scene. We build web apps and PWAs for them that are accessible from the start, as the Austrian Accessibility Act has required for many consumer services since June 2025, with EU hosting and work in English or German.
App development in Frankfurt
Frankfurt’s banks, asset managers and fintechs need client portals and internal tools that pass security review and fit DORA’s requirements for ICT providers. We build web apps and PWAs in English with strict tenant separation, EU hosting and the documentation your third-party risk team expects.
App development in Zurich
For international companies in Zurich we build web apps and progressive web apps in English: customer portals, internal tools and mobile-first applications that install from a link. Where a native store app is genuinely required, we say so up front and take on requirements, concept and project leadership instead of overselling.
AI consulting in Zurich
For companies in Zurich we combine practical AI with governance: assistants that answer from your own documents with citations, AI integrated into CRM, ticketing or Microsoft 365, and an inventory and risk classification that stand up to FINMA guidance and the EU AI Act. Swiss hosting is available where data requires it.

FAQ
Can you just fix our existing prototype code?
Sometimes, but generated code is often faster to rebuild than to repair. We assess it honestly and recommend the cheaper path.
Will our data stay in the EU?
Yes. We host databases and files in EU regions such as Frankfurt by default.
Do we own the code?
Yes. You receive the full code, access and documentation, and remain independent of us.
