My general advice to people is to not join a startup if a) you will lose out on salary, b) you will not get a title bump, c) you will not get GOOD equity (that is, equity that they can’t dilute to shit and keep you from exercising for a long time), and d) if you want to keep a semblance of a social life outside of work with people other than coworkers.
It sounds like you’ve won on a and b. What are your thoughts on c and d?
