This guide leaves out something extremely important that just fucked over a friend of mine: double-trigger RSUs. My friend thought he was getting a certain amount of stock annually, but in fact he only got it if he was still employed there when the company went public. So after six years they fired him right before going public a month later, and he got nothing. And in order to get any severance, he had to sign an agreement giving up any right to pursue any legal claims against them. I didn't even believe this was possible at first. Almost no startup equity guides mention this. Read your contracts very carefully, people!
