I've first heard of this special class of stock through The Founder Institute. It's basically a way for founders to protect from dilution by authorizing both Common stock and a special Class F (for Founder) Common stock, which has 10x voting rights over Class A Common.
Most of the people I've asked haven't seen this structure around, and a few other people advised me against using it because apparently VCs won't be happy with it (I'll let you know later in any case).
What do you feel about this kind of special stock for founders? Evidently as a founder you gotta feel good about it, but have you seen this around? Have you heard any stories of teams with this structure getting funded/busted?
If you can read legalese or are plainly curious (as I was when I first read the sample certificate), here's a link to download the sample certificate of incorporation with this special class of stock. I post this because when I downloaded it (like a month and a half ago) it was posted on the Founder Institute site for free too, so I'm assuming it is a public document by now.
Edit 1: I found the original link to download the forms, you can see it here.
Finally, is it possible that someone edits this post and adds a tag like: "stock" or "common-stock", and also erases this sentence. Thanks!
