As an employee I never trust those offers, and treat them like lottery tickets at best. Partially because of the financial shenanigans insiders can play to dilute those shares, and also because I find it hard to value the company. And as a founder, I might not want to hand out equity to avoid dilution.
I have sometimes suggested to get paid in something closer to debt instead of equity:
For example, a note that pays eg 1 dollar a month and can 'called' by the company in exchange for a one-time payment of, say, 150 dollar (or an equivalent amount of equity, if both parties agree).
Or perhaps something closer to a safenote? Or something completely different?
