Your business processes as a web app — MVP in 8 weeks, scalable to 10,000 users
Custom SaaS Solutions & Dashboards
Custom web applications, SaaS platforms, internal tools and business dashboards — from MVP to scalable enterprise solution.
Anonymized reference caseLogistics service provider · Frankfurt, 110 employees+
Starting point
Excel-based order management, 3 full-time positions for data maintenance, no real-time visibility for customers, no interfaces to freight carriers.
Solution & result
Custom web app: order management portal with customer login, real-time tracking, carrier API integration and automated reporting.
3 full-time positions freed up for value-adding work, customer satisfaction +40%, 12 carriers connected — all on one central platform.
Off-the-shelf software never fits 100% — and forces your processes to adapt
- Every off-the-shelf software has workflows that do not fit your industry — your team adapts to the software, not the other way around
- SaaS licenses: cheap for 10 users, expensive for 100, unaffordable for 500 — scaling costs explode as you grow
- No interfaces to your specific systems: data exchange via export/import, manual transfer, errors and lost time
A custom web app that maps exactly to your process
- Built for your requirements: every workflow, every business rule, every interface exactly as you need it
- One-time development costs instead of never-ending license fees — after 2–3 years, custom software is cheaper than any SaaS
- API-first architecture: connection to any system that has an API — SAP, DATEV, accounting, logistics, CRM

Responsive & PWA
Cross-platform use — also installable offline as a Progressive Web App.
Scalability
From 10 to 10,000 users — scalable architecture for sustainable growth.
Approach
How we work
Discovery
Requirements workshops, user story mapping and technical architecture decisions.
MVP Development
Rapid build of a minimum viable product to validate the core features.
Iterative Development
Agile development in two-week sprints with continuous user feedback.
Operations & Scaling
Monitoring, performance optimization and scaling as requirements grow.
We freed 3 full-time positions from manual data maintenance. Our colleagues now do work that truly adds value — and our customers see their orders in real time. That was unthinkable with Excel.
MVP Approach
Live in 8 weeks —
with real users
An MVP significantly reduces risk: you validate the core concept with real users before committing the full investment. What works gets expanded. What doesn't is caught early.
Weeks 1–2
Discovery
Requirements workshop: core processes, user roles, user stories, technical constraints. Outcome: a complete backlog and architecture decisions.
Weeks 3–4
Prototype
Clickable hi-fi prototype of all core features. Real users test it and give feedback — before a single line of code is written.
Weeks 5–8
MVP Development
Agile development in 2-week sprints. Every week: working software on a staging server. No progress reports — you see real features.
Week 8
Launch
Deployment to cloud infrastructure, monitoring setup, user onboarding and documentation. You are live — with real users and real feedback.
Architecture
Scalable from day 1
We don't build prototypes that get thrown away later. The architecture scales from 10 to 10,000 users — without a rebuild.
React / Next.js Frontend
Fast, responsive user interface built with TypeScript. Server-side rendering for SEO-relevant pages, client-side rendering for interactive dashboards.
REST / GraphQL API
A clearly defined API layer separates frontend and backend. Every connection to third-party systems runs through this layer — clean and testable.
Auth & Role Management
JWT, OAuth2, SSO (Microsoft, Google) and a fine-grained role model. Multi-tenant architecture for SaaS applications.
Cloud Deployment
Container-based deployment (Docker/Kubernetes) on AWS, Azure or German data centers. Auto-scaling, zero-downtime updates.
Fixed-price offer within 5 business days of the workshop
Integrations
If it has an API, we connect it. No system stays isolated.
Frequently asked questions
Everything you need to know about Web Applications at a glance.
01What does a custom web application cost?+
An MVP with core features starts at a fixed price of €20,000. Complete business applications with multiple modules, user roles and API integrations range from €50,000 to €150,000. After a free discovery workshop, you receive a binding fixed-price quote within 5 business days.
02What is an MVP and why do you recommend it?+
An MVP (minimum viable product) is the first working version with the most important core features. It lets you win real users and collect real feedback — before you develop more features. That reduces risk considerably: you build what is needed, not what you assumed.
03Which technologies do you use?+
Frontend: React or Next.js with TypeScript — fast, maintainable, scalable. Backend: Node.js, Python or .NET depending on requirements. Database: PostgreSQL, MongoDB or Supabase. Cloud: AWS, Azure or Vercel. We choose technology based on requirements, not trends.
04How do you ensure scalability?+
Cloud-native deployment from day one: horizontal scaling with containers (Docker/Kubernetes), auto-scaling during load peaks, CDN for static assets. We size the architecture for 10x your current volume — no rebuild when growth arrives.
05Can you connect existing systems?+
Yes — API integration is a standard part of every web app. SAP, DATEV, Salesforce, HubSpot, Shopify, your own databases: if it has an API, we connect it. For legacy systems without an API, we develop secure database adapters.
06Who supports the app after launch?+
We offer SLA-based support: critical errors <4h, standard bugs <24h. 24/7 hosting monitoring with automatic alerts. Further development in ongoing sprints according to your roadmap. You receive complete documentation and source code handover — no vendor lock-in.
Free assessment workshop — no obligation
In 60 minutes, we analyze your current situation and show you exactly which solution makes sense for your business — with a binding quote within 5 business days.
