Note to Founders: Have Vesting

I've been in startups where the vested equity was really low, and I left (I was employee #1). I've also talked with numerous people who thought about joining the same startup, and refused due to a number of reasons, but low equity was mentioned as one of the first reasons.
If you can get the legal angle sorted out, I'd personally find these sorts of documents useful. As for waiting for a version without "holes", that sounds like waiting until the software is perfect before shipping it :) It's not like a theoretically "bulletproof" set of templates would stop anyone from suing you anyway, if some company tanks and the investors are looking around desperately for someone to blame...
A side note, the book Founders At Work is an awesome read!
Personally I want to own my shares immediately. You never know what's going to happen and what technicalities will let VCs/the board/others fire you before you're vested.
