Owner-managed. Personal. Since 1998.
We are a small, focused software house in Cologne. We develop custom software for people who know what they need.
1998 – Foundation & Oracle Expertise
Ralf Dünkelmann founds oxalis Softwaresysteme für Wirtschaft und Wissenschaft GmbH in Cologne. From day one: custom software solutions for insurance companies and energy providers. Oracle Forms, PL/SQL and Oracle Designer form the technological foundation.
2005 – From Forms to Web
The transition from Oracle Forms to Oracle APEX marks the leap into web development. Web-based enterprise applications for insurance companies and public administration become the core business. Projects grow, technology modernises.
2014 – Second Company & Open Source
With growing demand, oxalis Individualsoftware GmbH is founded. Go and PostgreSQL complement the Oracle world as a powerful open-source alternative. Vue.js becomes the primary frontend framework. The focus sharpens on tailored solutions for mid-sized companies.
2020 – Mobile & Cross-Platform
With Flutter, oxalis enters app development for all platforms: iOS, Android, web and desktop from a single codebase. Projects in healthcare and for mid-sized companies benefit from the new platform breadth.
Today – AI-powered development
AI tools like Claude Code revolutionise our working methods. What used to take months can now be delivered in weeks – at higher quality. The combination of over 25 years of experience and modern AI tools is our greatest strength.
Our approach
We believe that good software is created through direct communication. No project managers as middlemen, no ticket queues. Our clients speak directly with the developers who build their software. This creates understanding, trust and better results.
Cologne, Germany
Our office is in Cologne-Porz. From here, we develop software for clients across Germany and Europe. European hosting, German data protection law, personal availability – that is our promise.
