For whom
Three typical starting points.
Companies & organisations
You want to digitise a process, serve customers better or replace an outdated tool.
Starting point: a process that costs time today.
Companies & organisations
- Digitise workflows instead of Excel & paper
- Customer portals & self-service
- Connection to ERP, CRM & existing systems
- Roles, permissions & approvals
- Operation & care after launch
Founders & product owners
You have an idea for a product and need a team that thinks it through and builds it.
Starting point: an idea or a pitch deck.
Founders & product owners
- Sharpen the idea, define the scope
- Clickable prototype to show around
- First version (MVP) with real users
- Technology that grows with you
- Honest view on effort & approach
Teams with an existing app
Your app is running but stuck – technically, in usability or in further development.
Starting point: a live app or a prototype.
Teams with an existing app
- Assessment of code & usability
- Fix bugs, crashes & loading times
- Dependency & security updates
- New features by priority
- Takeover from the previous team
Process
How a project runs with us.
Clear steps, visible interim results, no black box. The scope of each phase depends on the project.
Understand
Initial conversation about the problem, users, environment and goals.
Result: shared understanding of the task.
Concept & scope
Prioritise features, sketch flows, define the first version.
Result: a comprehensible scope and a rough plan.
Design & develop
Interface design and development in iterations with regular interim states you can try out.
Result: a working application.
Launch & further development
Release, operation, maintenance and the next expansion stages based on real feedback.
Result: a live product that keeps improving.
Included
Good software is more than code.
Product thinking
We ask why before how – and also advise against features that add no value.
Product thinking
- Workshop on goals, users & success criteria
- Prioritised feature list
- Clear scope for the first version
- An honest no to unnecessary features
UX/UI design
Interfaces that are understood without a manual, accessible and consistent.
UX/UI design
- User flows & wireframes
- Custom design system instead of templates
- Accessible according to WCAG 2.2 AA
- Clickable designs for sign-off
Robust technology
Modern, maintainable foundations, clean data structures and security from the start.
Robust technology
- Modern, widely used technologies

- Automated tests for core rules
- No vendor lock-in – the code can be handed over
Data protection
Data minimisation, hosting and access concepts that fit European requirements.
Data protection

- GDPR-compliant hosting & role concepts
- Encrypted transfer
- Deletion and retention periods
Performance
Fast loading times and smooth operation – on mobile devices too.
