My advice to people who want to work in a startup is always very simple: Ignore any equity. If you'd take the job without any equity then take the job. If the equity is part of your reason for taking the job, you probably shouldn't take it. Base rate neglect[1] means we are terrible at evaluating the probability of equity being valuable. For every story about someone making millions out of their equity when the start…
So why the hell do startups bother offering equity? It seems like for the founders there are only downsides in offering it, while for the employees there is no upside at all. Perhaps a better model for a two founder startup looking for a first employee is to just find a third partner who will only take equity (that is in double digit percentages), then actually start paying only salaries to person 4+.
FWIW, I joined a startup as that third partner (domain expert + execution guy), taking 10% of the equity while collecting 70k/yr (my base rate is north of 200k/yr otherwise). It would have brutalized the startup's seed money and jeopardized them if I somehow didn't perform and deliver.
