In conjunction with long-time associate Dennis Hobson, former WBA and IBF light-welterweight champion Khan has formed Super Fight Promotions, with 2010 Commonwealth Games bronze medallist Haroon immediately revealed as the first fighter.
The elder Khan was also an amateur of note, winning Olympic silver as a teenager, and is happy to guide his younger brother through the professional ranks.
“I’m delighted that Haroon is the first fighter to sign for Super Fight Promotions," Amir Khan said. "He’s got a lot of talent and I know he can achieve a lot in the professional game.
"His amateur record will serve him well and I have no doubts that his decision to turn professional will prove to be a very fruitful one.
"Super Fight Promotions is a company which is going to make big waves in boxing as we actively seek to sign the very best young talent around.”
Haroon, 20, is a flyweight in a similar mould to his brother. He courted controversy by boxing for Pakistan at the 2010 Commonwealth Games after being overlooked by Great Britain.
He went on to beat Andrew Selby - the man selected ahead of him - in the quarters.
