I’m considering joining a startup, I think they could be acquired before a year is up by someone, their typical 1 year cliff/4 yr total options wouldn’t be vested. The usual answer is the new company will surely want the engineers and offer them new stock or equity, if not too bad. As is common, half the comp is in options, and lower cash comp at this startup. I’m considering whether I should ask for my options to immediately vest in the event of a buy out or liquidity event. It’s not that much money or options that the overall company will care. Should I ask for 1 year, or all 4 years, I’m uncertain if it could poison the well. Is this even something they would do?
