Where ingenuity

meets reliability

Some developers tinker.
Some build.
And then there’s Rüdiger.

Rüdiger is the guy who was already experimenting with language models in 2010, when most of us thought GPT was the abbreviation for a new propulsion system.

Today, as then, he is the heart of [j]karef, the manufacturer of JOUO and other pretty awesome technologies. He doesn’t just build software – he thinks his way into worlds that others haven’t even considered yet.

And yet, he’s not some aloof tech guru, but a down-to-earth partner who makes sure everything runs smoothly. That’s exactly why we love working with [j]karef.

Founder of [j]karef
Early adopter of hacking
Working on AI architectures as early as 2010, when ChatGPT was still a distant dream
Loves lean solutions and hates overloaded systems
Boils complexity down to its essence – fast, practical, reliable

Because [j]karef doesn’t just supply software – they think along with you.
Because we know them, trust them and work with them ourselves.
Because it’s good when everyone focuses on their strengths:
➡️ [j]karef builds.
➡️ We bring it to you.

Technology? They can do it.

Sales? We do that.

We handle sales for [j]karef – so that Rüdiger and his team can concentrate fully on what they do best: developing really good technologies.

The software from [j]karef doesn’t just run – it solves real problems. JOUO, for example, was developed based on real-world experience: while Rüdiger was tasked with measuring the degree and quality of digitalisation in companies in Brandenburg, he developed a tool that identifies weaknesses – quickly, clearly and reliably. That’s how JOUO was born.

And us? We knew right away: more companies need to know about this.
