I don't know where that statistic came from but it's nowhere close to accurate. Less than half of the startups we funded in the first 5 years of YC have died.
Also, he average valuation of all YC startups through w2014 (i.e. with enough time to have raised a first round) is now over $100MM.
What were the causes of failures for those YC alums that did fail? (Again, not trying to be combative whatsoever. I'm genuinely curious, if you're able to provide the data without compromising YC from a business perspective).
According to Wikipedia, their best-known funded companies are: Dropbox, Airbnb, Coinbase, Stripe, Reddit, Zenefits, Instacart and Weebly.
Dropbox - Not public, probably not profitable
Airbnb - Not public, might be profitable, lots of legal questions.
Coinbase - Not public, raised $100m+, no idea if it's profitable
Stripe - Not public, raised almost $200m, almost certainly not profitable
Reddit - Acquired by Conde Nast (private), might be profitable.
Zenefits - Not public, probably not profitable, raised ~$500m
Instacart - Not public, not profitable, raised ~$300m
Weebly - Not public, might be profitable
So I'd say their track record isn't great on that front. I don't know of any meaningful ($1bn+) IPOs of YC companies (not to say that they don't exist). The fact that I had no idea what Weebly was until a moment ago probably means it's not one of their success stories. I suspect DropBox will IPO at some point, but after Box's IPO, they have an uphill battle to prove that they won't be the same dud. Coinbase I had forgotten existed, so I'm really curious what their deal is (especially considering their valuation is so high, I wonder if they can support it anymore).
Calling Dropbox having an uphill battle to prove their valuation is quite an understatement.
Box is trading at about 6x their forward revenue in valuation, versus cloud industry's 10-12x average, and during the last Dropbox round it was rumored it was valued at 40X its forward revenue.
Meanwhile Box is winning major partnerships and customers left and right and the market still hates it, I really wonder how Dropbox is gonna tell their story considering their vast consumer user base is a liability instead of asset when it comes to profitability.

But how many were successful, in the sense of paying back their investors? The most likely outcome of most VC investments is a "zombie", a company which can pay its own operating systems but is a net loss to investors. The usual VC stats are that about 10% are wins, 20% go bankrupt, and the rest drag on for years in zombie mode.
