Ask HN: Looking for Python companies in Germany

I'm currently doing a bit of research and would like to find companies who are working with Python and are located in Germany. I'm not looking for a job (yet), but I want to do the research on time.

Since I'm getting really tired with the all the startup hype, I would like to exclude all the social|buzzword|disrupting|lean|web2.0 companies, as well as large corporations and outsourcing agencies. I'm looking for companies doing some interesting (and meaningful) work.

I would be grateful for any info you can provide (website, what do they/you do, etc).
