Our manifesto

Digital craftsmanship for your success

We don't build software for its own sake, but as a pragmatic solution to real business problems.

Our mission: transparent consulting, clean code and a partnership in which we dare to say ‘no’ if we believe it could help your project.

We see ourselves as your strategic partner and believe ...

that business value takes precedence over a flood of features
We do not develop what is technically possible, but above all what drives your economic success.
that a comprehensive understanding is essential
We don't write a single line of code until we have fully understood your business objectives.
that software development is a craft
We deliver enterprise-grade quality that performs reliably even under heavy loads.
that high quality is sustainable and best to reduce costs
Clean code is always cheaper in the long run than ‘quick hacks’.
that clear communication on equal terms is fundamental
We communicate clearly – especially when it comes to avoiding unnecessary costs.
that mutual trust is the basis for successful cooperation
Only cooperation based on partnership will enable us to move forward together in the long term.

Therefore, we guarantee ...

Strategic advice instead of just implementation
We critically examine requirements with all our experience to avoid bad investments.
Solutions with ‘legacy protection’
We design and develop technical solutions that make economic sense and not only work today, but will still be maintainable and expandable in 5 years' time.
Investment security
We provide realistic cost planning with no hidden costs.
Agile precision
We offer full visibility into progress at all times and the flexibility to respond to changes – based on solid data.
Fast time-to-value
We prioritise features so that your product generates revenue or value as quickly as possible.
Dedicated contact persons throughout the collaboration
As an owner-managed agency, we develop 100% of our work for you from Cologne and are your permanent point of contact for the long term.

PAGOPACE

We were already able to offer our customers good hardware with our payment ring. However, Johnny Bytes helped us to build the perfect complementary software to take our product to the next level. We were kept up to date at every stage of the app development and were able to make requests immediately. With the new app, we can also sell our rings in retail stores, as customers can link their rings directly to their payment card on their cell phone.
