They give you up to 30k for 6 months, and it is funded by the German ministry of education. Their strive for a very easy application process where you just need to write an email and send a link of your open source project, and a list of goals you want to achieve with the money.

So it passes the smell test and seems like a great opportunity for European oss devs. I couldn't find any info which explicitly states that projects outside the EU might be funded.

I had to disable CSS to see the answers, though.
