Analyzing Y Combinator
"80 - Active (25 having received further investment rounds)"<p>The internal contradiction here should have set off
some alarms.  Are the other 55 supposed to have made
it to profitability without raising any further money?<p>According to our records, 89 of 144 startups we funded up to this summer are still alive, for some definition of alive.  When startups die, they usually die gradually, so it's hard to say when a startup is actually dead.<p>Some other mistakes I noticed:  Nearly all cycles have the wrong number of startups.  The furthest off is W07, which he lists has having had 15 startups but actually had 12. There have been two mergers, not one (Ninite is also a merger).  YouOS didn't die; it morphed into Project Wedding, which was acquired.
8aweek didn't die either; that's now SocialBrowse.  
Nambii and pocketfungames are the same company,
as were  Boso and Auctomatic. 
Chatterous, iJigg, and Ididwork  are all still alive.  There's at least one startup listed as active that has been acquired, but it may not be public knowledge.<p>I've never heard of Innovation Fuels.<p>It doesn't seem fair to accuse us of "lack of transparency."  Every startup launches publicly when they're ready, after which we list them on our site.  It wouldn't be appropriate to list them before they've launched (or more precisely, it would launch them).  We're usually not supposed to disclose when they raise additional funding or get acquired.  And we're not always sure till long after the fact when they die.
