My brother look for that person in your life that has contributed more than others towards your goal as a founder. S/he is your co-founder.
Could be your mom and her many fastings and prayers. Or your sister, her acceptance and many support, even when your parents don’t want to wrap their heads around what the heck you’re doing with your life.
Or, perosnally speaking, your wife who is your die hard, number one fan.
A tree can’t even make a grove. Talk Forest? mba nu!
