History

Why diffcraft exists

Founding a company was never my original plan. But during my time at FAU’s Professorship for Open Source Software, I had the opportunity to work towards a spin-off in open data and data pipelines alongside my PhD. The spin-off did not come together, mainly for organizational reasons. The idea of building a company stayed with me.

After finishing my PhD, I wanted to find out where that idea could lead. I value the freedom to follow subjects I care about, take responsibility for them, and keep learning about the world through the work.

What we stand for

A technical partner

End-to-End Engineering

We connect product decisions, implementation, delivery, and operation instead of treating them as separate concerns.

Sustainable Partnerships

We optimize for long-term product success through honest advice, shared ownership, and maintainable software.

Open Source First

We build on proven open-source tools to reduce costs, avoid unnecessary lock-in, and keep solutions maintainable.

Iterative Delivery

We create value early, learn from real feedback, and adapt the next step as our understanding improves.

Our goal

We meet you where you are

Whether you have an initial idea, an established process, or an existing system, we combine software engineering and technical consulting to find the right next step with you.

We look at the people, processes, constraints, and tools already in place. From there, we shape a solution that fits your situation and take responsibility for making it work.

While developing my psychology x AI app, Georg translated my domain-specific requirements precisely into detailed technical features. His transparent project management allowed me to contribute proactively and track our milestones at all times. I felt my project was in the best hands and wholeheartedly recommend him for complex AI-based projects.

Georg is an excellent engineer (and researcher) with great values. We often work together and I especially value his help for complex backend and DevOps projects. We can discuss a requirement once, on an abstract level, and I can rely on the fact that it will be done to a high standard :)
