Justin Bieber is the "most talented" boy Scooter Braun has ever met.
The 18-year-old popstar is signed to Scooter's Raymond-Braun Media Group record label.
The talent manager also represents Carly Rae Jepsen, Psy and The Wanted but says Justin stands out with his talent and drive.
Scooter revealed his career almost fizzled out, but he was given a lease of life with client Asher Roth's hit I Love College and Justin's quick rise to fame.
"I was able to double down and really continue supporting and nurturing Justin," he explained to Entertainment Tonight.
"He is the most talented kid I will probably ever meet in my life and one of the most hard-working kids."
Scooter is close to his brother Adam, who runs Pencils of Promise, a non-profit organisation which builds school in the developing world.
The music mogul would never force his clients to be involved with the charity, but is thrilled when they sign up of their own accord.
"I run my business like a family, so all my artists are like family. Justin is family to me," the 31-year-old fondly said.
"We've gone on family vacations [where Adam] was his roommate for two weeks. Justin, at a very early age, because he saw what Adam was doing, was inspired the same way I was and chose to be involved."
Justin first got financially involved in the organisation by drawing on his popularity.
A wealthy father of one of his fans offered him $10,000 to meet his daughter backstage and the young star agreed, under the condition the money would go to Pencils of Promise.
"This was very early on in his career. That's a lot of money. I walked back, had a conversation with Justin, and his immediate reaction was, 'Well, [doesn't] $10,000 build one classroom?' and I said, 'Yeah,' and he goes, 'OK, tell him to come back and I want the money to go to Pencils of Promise,'" Scooter recalled.
