Did you check out The Macro - http://themacro.com/ ? Yes the info disclosed by YC for each startup is still limited but better than nothing in the before.
Definitely helpful, but AFAIK only about a dozen startups from the 100+ startup batch have been covered so far (https://www.google.com/#q=%22meet+the+batch+s16%22+inurl:the...). I can imagine the coverage will double or triple by demo day, but I'm skeptical that all startups will be covered. Btw, I love the /data subsection of your website!
