No matter what a startup ever promises, they never make good on it. And worse if it does manage to somehow get legs, they will screw you out of any payout you would be getting anyhow. If you were still unmarried and without kids and hated your current gig, sure roll the dice. But in your situation, I would not roll the dice with no obvious upside if I were in your place.This is my gut too but from what they've told me
1. They have funding secured for many years to come
2. They already setup a manufacturing facility
Still I'm being a bit cautious with this. I'm gonna go through the whole process and see what I can feel out. It's a startup so being in my 40s I'm a bit hesitant to go to something volatile.
