Blueprint for your product’s success
What is Prototype?
Functional model of your product aimed at de-risking your investment. You visualise the user flow, click through key interfaces, and experience the product before any development. It is core foundation of our software design process, fully included in your initial project investment.
How it works
Operational Sequence
We do not believe in lengthy, opaque development cycles where you only see results at the very end. Before committing to a full production build, we validate your system architecture using a tight, agile cadence.
We ship high-performance and intuitive usability solutions.
Discovery Workshop & Roadmap
We begin with a comprehensive discovery and technical clarification sit-ins, followed by workshops online or onsite.
Site/app Structure Mapping
Detailed content hierarchies and navigation blueprints. We map what goes where and why, ensuring every user flow is backed by clear operational logic.
Wireframes & Interaction Logic
We design low-fidelity structural layouts paired with precise behavioural mapping of how screens display, interact, and respond to user inputs.
Visual identity & UI Components
Complete brand styling, typography, and a centralised UI component library. We craft the subtle, consistent details that make an application feel cohesive and premium.
We build high-fidelity, interactive mockups deployed for real-world user testing to validate functionality, gather field data from internal teams and stakeholders.
What to Expect
Our Prototyping Timelines
The time required to lock down a prototype depends entirely on your project’s underlying complexity and structural scale
01
Standard Frameworks
1 - 2 Weeks
For straightforward interfaces or single-utility business tools, interactive models.
02
Complex or Highly Specialised Systems
4+ Weeks
The prototyping phase can run roughly 4 weeks. We use this dedicated window exclusively to stress-test layout feasibility, refine workflow ergonomics for non-technical field users.

Our 6-SDLC Process — How we work
Software Development Lifecycle
We do not employ a single, rigid path to developing software. Each business system demands a tailored approach. Our overarching operational sequence is a highly consistent, predictable, and designed framework.
We host a deep-dive 1-2H kickoff workshop. Whether your team is on-site in Bonn or remote, the session brings all key stakeholders together to map raw business requirements
Interactive Prototyping
We deliver clickable, interactive prototypes. Your team can navigate layouts, trigger interfaces, and physically feel how the software handles actions. We use your user feedback to refine behaviour, and alignment before heavy engineering begins.
Database Architecture
Our lead engineers sit down and map your data relationships, access controls, and system pipelines to guarantee long-term maintainability and high-volume performance.
Incremental Sprint Implementation
We build in high-transparency sprint cycles, deploying functional, working updates to your staging environment every 1 - 2 weeks. Routine check-ins allows you to watch the system grow organically and request minor course-corrections in real time.
Comprehensive Testing & Deployment
We back the completed system with our mandatory automated testing suites, run final end-user validation, secure your data paths for absolute GDPR compliance, and smoothly migrate the architecture.
Ongoing Support for Maximum Lifetime Value
Post-launch, you benefit from proactive maintenance, rapid enhancements and continuous upgrades.Your software remains modern, reliable, evolves with your business needs.
→ WE DO IT FOR YOU
Online / Offline Mobile Solutions
Cross-Platform Development → Android & iOS
The success of a mobile app depends significantly on its visibility, where your users are. We build applications that run on both major platforms, end-to-end → architecture, development, testing, App Store and Google Play submission, and the long-term maintenance that follows. We prioritise a fluid user experience featuring smooth animations, fast load times, and full hardware integrations.
Rather than splitting your budget across 2 separate teams, across different codebases, we take an efficient, modern approach. We leverage React Native, develop shared codebase for both platforms with unified business logic that powers both platforms.

Featured Work
Pia Health — OCR app for scanning medical invoices & automating reimbursement in Germany
Pia Health digitises the complex reimbursement process for privately insured patients in Germany. The mobile application utilises Optical Character Recognition (OCR) paired with a locally hosted Large Language Model (LLM) to instantly extract critical metadata from scanned medical invoices with absolute precision.
The Transformation
Eliminated manual form-filling, postal submissions, and fragile Excel trackers. Document turnaround time was slashed from 2 hours to 5 minutes, increasing processing throughput by 4x and capturing previously forgotten billables.
Compliance Protocol
Fully GDPR-compliant and hosted exclusively on sovereign German servers. Absolutely zero US-based cloud services exist within the critical data path.
Featured Work
Safetyworx365 — DGUV-Compliant Digital Safety Training for Construction Workers
Safetyworx365 digitizes mandatory annual safety instructions and accident prevention regulations (UVV tests), delivering them online across 10 languages and automatically generating certified PDFs upon successful completion. The platform was designed from the ground up for a multilingual, non-technical workforce operating in a high-turnover industry.
The Transformation
Transitioned archaic, offline training days into a seamless digital pipeline. Built a unified platform that integrates a multilingual training hub, a digital Personal Safety Logbook (PSL), and a B2B online commerce shop under a single architecture.
Operational Resilience
Scaled training compliance across diverse teams without interrupting daily job-site momentum or adding to administrative overhead.
Featured Work
Therabits — AI-Generated Patient Simulation for Psychology Education
Built for the University of Witten/Herdecke. Pre-rendered AI avatars replace the live patient for clinical practice; student recordings remain on the university’s own servers; no real-time LLM in the student session.
The Transformation
Enabled clinical psychology students to run training at scale. Students record their therapeutic responses in real time, with all video and audio data remaining locked within the university’s database
Compliance Protocol
Strict GDPR compliance and data sovereignty. No real-time LLMs or third-party APIs interact with active student training sessions.
Custom Web Application — The Process
Deep-Dive Process Analysis
Our architectural process begins with rigorous cross-examination. Before recommending a technical path, we analyze your core business workflows to understand:
→ Who are we building for?
→ Identify specific operational bottlenecks we are solving?
We give you completely honest, platform-agnostic advice on whether your use case demands a Progressive Web App (PWA) or a Native Mobile application.
UI/UX Prototyping & Visual Alignment
We work in parallel. We validate your operational logic, we shape low-to-high fidelity user flows, structural wireframes, and clickable, interactive prototypes.
With this, you can experience the exact ergonomics, click through key actions, and collect user validation before a single line of production code is written.
Full Stack Agile Development
We build in highly visible, 2-week sprints, combining a robust Laravel backend with dynamic frontend environments like React or Livewire.
We design a comprehensive high-level system architecture diagram mapping every critical touchpoint, including, API integrations, centralised data storage, authentication protocols, and background orchestration layers.
You receive functional, working builds to test at the end of every sprint, and you speak directly with the senior developers handling your project.
Launch, Store Submission & Continuous Support
We execute a zero-downtime deployment, configure real-time system monitoring, and smoothly transition the application to infrastructure that you fully own.
If your product includes a native mobile component, we manage the entire App Store and Google Play compliance and submission process. Post-launch, we wrap your platform in proactive support retainers to ensure seamless dependencies updates and uninterrupted performance.
Maintenance & Growth
Remember, launch is the beginning, not the end.
We handle hosting, ongoing maintenance, and continuous development of your app, keeping your mobile solution future-proof and adaptable to evolving requirements.

FAQs
Still unsure about anything?
We primarily use React Native and Expo to build a shared codebase for iOS, Android, and macOS. This saves time and cost without compromising on performance or user experience. The result feels fully native to the end user.
If your app requires complex server-side logic, we connect a Laravel backend via API. Laravel is our speciality and enables secure, scalable backends for your application.
Yes, this is one of our core competencies. Using a bespoke Laravel backend, we securely connect your software to third-party systems such as Microsoft Dynamics 365 Business Central, HubSpot, or custom databases.
Before implementation, we thoroughly analyse how best to integrate with your existing systems. Our automation solutions are also designed to fit seamlessly into your current infrastructure.
Costs depend largely on the scope of features and the complexity of the integrations required. Following an initial consultation, we produce a detailed roadmap that clearly outlines the effort involved across design, backend development, and store release.
Yes, of course. We’ll guide you through the entire review process for the Apple App Store and Google Play Store and ensure that all technical guidelines and data protection requirements are met, so that your app can be published without a hitch.
Security is our top priority. Using modern encryption protocols and a secure Laravel backend, we ensure sensitive business and user data is transmitted and stored in full compliance with GDPR at all times.
An app must keep pace with new OS releases. We offer long-term support and maintenance contracts to optimise performance and continuously extend your application with new features.
This includes bug fixes, performance optimisations, and the integration of new platform features — whether iOS, Android, or macOS. As a long-term development partner, we're with you well beyond launch day.
