Yes, the hardest thing is probably to get a flat and register a business without speaking German and these are one time things, no ongoing stuff.

The start-up scene speaks English fluently and buying stuff etc. doesn't need much talking.

The start-up I work with has 2 employees who don't speak German at all and they say it's only a problem when they are in smaller villages.

Registering a business is literally going to the "Gewerbeamt" and answering their questions about what you want to do. You will then be contacted by the tax authorities. I would then just search for a tax adviser, who speaks English.

If you want to incorporate a business, you do not necessarily have to do it in Germany, it is the EU after all.

Ah sure, yes I forgot that you can create a company in the UK and simply run it from Berlin without much hassle.
