We have some awesome YC alum in London (and the YC community there is growing), and we're excited that they'll be joining us in July. We'd love to do something in Berlin as well.
A "how to turn your project into a company? should you, and why?" talk by YC (ideally, with European YC company founders, ideally in the product spaces most interesting to CCC hackers) would be awesome. The downside is it's 27-30 DEC in Hamburg.
However, looking at the current list of YC partners [2], I don't see many that might have ties to Europe, such that they'd be visiting much (never mind the imposition of giving up family/holiday time to give a 'work' talk).
Here in Vienna, we'll have an event with quite a few YC alumni on May 29: http://foundertalks.org
We do not have the means yet to make it free, however. We basically started this a few weeks ago, because we felt that something like startup school is missing in Central Europe. I guess you must have felt the same :-)
EDIT:
P.S.: After our event, I'd be happy to give you some feedback regarding what kind of questions/interestes/etc. European founders voice in such a setting. It's an awesome experiment, I'm really looking forward to it.
There's a great startup community here in London and I reckon that plenty of people will be willing to help make things a little bit cheaper by letting SUS attendees crash on their sofa.
I've dropped Sam an email to see if YC's interested.
I wonder how YC could do a "Startup School Asia" -- in general, for a larger percentage of Asian founders, travel between countries in Asia is difficult, compared to European founders (where IMO you could have SS in virtually any major city and be no worse than 50% as good as any other in terms of access; London is great but expensive, Berlin would be my pick.)
Singapore is probably the easiest and best choice for Asia, but there are strong arguments for HK/SZ, Beijing, Shanghai, one of ~10 cities in India, etc.
