That's a serious landmine for employees who get part of their comp as stock options.
Edit: edited to reflect what I actually wanted to say (future companies instead of current company)
I have declined a number of offers over the years when my research into the CEO showed they were not the people who could get a company over the finish line, and have generally been pretty accurate in the eventual fate of those companies. Correlation isn't causation, but the CEO is the biggest win/lose variable in the mix.
I'm sure it would come up in future investors' due diligence but I'm not sure it's information they're required to disclose to employees.
They won't give it to you of course, which is why employees should always value illiquid private company stock at zero.
