Awesome post. Definitely good timing as I was about to start an Ask HN around this as I go through the process.

I've also asked about early exercise (83(b)) and term sheets, if there are bad terms i.e. liquidation pref, anti-dilution etc but not all companies are willing to share this info.

Also, I am curious about why companies don't just have a black box formula output generator, with your equity offer value, saying this is our projection and based on our current termsheet if the company exits at this value your options are worth X, with the option of dilution built in.
