Every single employee who joined prior to this year will make 8 figures+ off this exit.
I guess if I found my already-vested shares were worth $4 million, I'd still be motivated to get the remaining $8M by working a couple more years. How surreal that would be, to find yourself extremely "FIRE" (Financially Independent, Retire Early) but also kind of obligated to yourself to keep working hard for a few more years, as walking away from that kind of money seems crazy.
