A very important question is missing imho — is there a buy back plan available - at least just enough to pay exercising amount and the tax? I have finished a year at my startup. I’ll be leaving soon. If I exercise my vested stock it’ll be more than half of my current CTC (yeah, that’s pre-tax). So that’s what I’ve decided that I do not want to be an investor in this company paying paying back the salary (which is less than what I’d command otherwise) it pays me! PS. I knew the risks and now I’ve lived it. Never again!
