Seems like a good tool for preparing pitch decks.

Three questions:

1. Who are the 50somethings?

2. Why do 15% of the startups have just one founder?

3. How many women founders?

1. I wondered the same thing.

2. Guess the solo founders hack the system: http://news.ycombinator.com/item?id=4402110

3. AFAIK, YC doesn't release numbers of female founders. Danielle Morril is one.

That's a lot of people hacking the system.

As their network grows, more and more people will find the back door. In that way they'll become more like 500; those with referrals will have preference.
