1297 YC companies (from here: http://www.ycombinator.com/press/)
860 YC companies listed as either active or acquired (from here: http://www.ycombinator.com/companies/)
= 33% failure rate
That's a lot higher than I would have expected, to be honest.
(78% active, 12% acquired, on a base of 800 companies)
Techstars and YC appear to have pretty dramatically different philosophies on selection, which influence this.
The giveaway is usually a blog or social media accounts that haven't been updated in years.

Stay classy, YC. I'm sure it would have cost a fortune to keep the domain up.
This one might be tougher than usual since the functionality that's very visible is probably dead whereas the links on the bottom containing useful info are tiny and look like the background. You at least see the right site, though.
*I haven't ruled out that YC has no ownership in the squatter, so, they may still "do".
This is not enough stake in the preferred shares to dictate anything.
Before, their stated policy was never to follow on, in order to prevent signaling risk.
If you want to ruin your SEO, I assume this is a good idea.
(I figure there is enough data here to make a fun "acquired/defunct/soldiering on" guessing game?)
Also, at least one of these startups has gone full circle, started failed stopped and was then reborn as a blog on entrepreneurship:
18 months ago, a small business owner asked me to solve a problem they have. They said they tried many existing solutions, and none helped. So, it turned out, it's the same problem I'm trying to solve for last 8 years, for my personal use; was put on the back burner, and did not think it has a big business potential. So, I've already spent so much time finding a solution in the past, and did not take me much time to find a solution to fit their needs.
fast forward till today, and I got alpha quality solution; working on it over the weekends. while working full time to pay mortgage and feed my family.
if I apply to YC, it means I have to quit my job, move to silicon valley (I live in SoCal) and moving away from my newborn baby, which is not practical, since we don't have family to help with the baby. and my wife on her own cannot take care of the baby, get groceries, do the house stuff.
if I apply to YC fellowship, there's not enough fund to justify quitting my full time job and focus on this company.
My only option seems to be to keep working on this product for next 6 months, putting 10-20 hrs over the weekend, and have slow progress.
I've talked to several businesses and they all agreed, they have the same problem, and they want solution right now, and willing to pay $200 to $2000 per month depending on features.
I wish there's a hybrid option, something like investment of 80K for 2-3% (similar to Fellowship, but more funds) and requirement to fly once a week to meet with YC partners and report on progress.
Also, $80k for 3% is a far better equity proposal than YC. $80k for 5% would be equivalent. That said, I can't imagine they'd splinter themselves any further. I think the way they've set themselves up works great for them, obviously they can't please everyone.
If you really have that much interest for your idea, get several LOI (letter of intent) notices from your potential customers and take it to investors. That should get you a lot more than $80k.
It sounds like you have a great potential business. The size of the addressable market will determine whether or not you could have a startup  as defined by PG. Generally speaking, YC only wants to fund startups in their main program, which would be the one that would give you enough capital to actually make a run at it.
When we did YC (S13) we had three cofounders that all had families and single incomes. We made it work. We rented an apartment and lived/worked together for a few days during the week, and returned to our home offices the rest of the time. You could find a room to rent somewhere if you are a solo founder. Some used credit cards to float things. You'll have to get uncomfortable...
Part of doing a startup is about sacrificing bits of your life for your business. Investors (including YC) want to make sure you are all-in. I would be surprised if you would be able to raise any capital from experienced startup investors while working part-time on the project. They typically want you to have already dove into the deep end.
If you don't have a startup on your hands, but instead have a great small business, there's nothing to be ashamed of there and you can probably find some investment from local high net worth investors if you do some networking. You can test that with pre-orders or LOI's or something of that sort. However, those investments are probably going to be more "Shark Tank," full of onerous terms and potentially much more dilution for you as a founder.
That assumes that they have enough savings to look after their family until they're making enough profit to take a reasonable salary.
But not his baby. Some things are non-negotiable.
I've also been in your exact situation a number of times; much of my past consulting work was because I'd already developed a solution for something for my own personal use.
Also there are other accelerators if you really want to go to one (ex: Digital Ocean is out of TechStars).
There also hundreds of other accelerators. Though I can't really recommend doing any accelerator while you have a 1-year-old. (But you also don't really need an accelerator to get your MVP done.)
For example, filtering on s2006 only returns Scribd, but as YClist shows, there are 9 other startups in that batch.
If you think there is more interest in non-dead companies, you could add an extra filter/selection box.
*if I remember the statistic correctly
It doesn't include all of them, just those with a blog feed.
