Niyi is a son of the 3rd Richest Black Man on Earth, Otunba Michael Ishola Adenuga,

The Chairman of Globacom and CONOIL PLC.
Niyi Adenuga Oversees Some of his Father’s Enterprises in North and Central America.
Niyi is a Billionaire on his own, but just like his father, they are extremely private human who cherished a quiet life and getting things done behind the scene.
You will never catch Mike Adenuga on social media. He doesn’t attend social events and functions. Even during his mother’s burial, he didn’t attend the reception and he rarely grants interviews.
That’s Mike Adenuga kind of life. He only sees those he wants to see. When he wants to see them. He constantly tells his friends and associates that he is not interested in competition or unnecessary attention.
All he wants is to keep extending and expanding the frontiers of entrepreneurship and quiet philanthropy.
So, Niyi got this attributes from his father. He is rarely spotted in public too, very few People know what he looks like, even on his wedding in 2017 Cameras were not allowed.
Some people simply love to enjoy their wealth in silence. They hate exposure and undue attention.
