I wonder if he was an early bitcoin investor - his tag at the bottom says bitcoin (heart) before it says "father" so maybe his path was paved with that?
It doesn't take much to be a qualified investor (angel investor). And I don't mean to downplay it or anything either. Really just making the point that good on him for realizing you have to get out and sell. I cheer for anyone that can be an engineer and sales lead. Powerful combo.
Who knows.
