London, UK - British entrepreneur Jamal Edwards has died at the age of 31, according to his manager.

Edwards gained fame from setting up new music platform SBTV – helping to launch a string of UK music careers, including Dave and Jessie J.

His manager told the PA news agency that Edwards died on Sunday morning. The cause of death wasn't immediately clear.

In 2014, the then 24-year-old was awarded an MBE for his services to music.

Edwards was a teenager when he decided to launch the youth broadcasting and production film SBTV to upload clips he recorded of his friends performing on the estate where he lived in Acton, west London.

By 2014, he had amassed an estimated fortune of around 8 million pounds ($10.9 million) and worked with the likes of Jessie J, Emeli Sande, and Ed Sheeran.

Speaking to PA after receiving his MBE, he said he started SBTV to give his friends a platform.

He added: "It was a frustration of going to school and everyone talking about 'how do we get our videos on MTV'."

"YouTube was like a year old. I was like 'I've got a camera for Christmas, I'm going to start filming people and uploading it'."

"Everyone was looking at me like 'what are you doing, like you can compete with these major corporations,' but I think I was early enough to believe that I could make a change."

In the same interview, he described his working relationship with musicians as "symbiotic".

"50% is the talent and 50% is the platform," he said.

"I try to focus on people that haven't got the platform. As well as getting a really well-known artist I want to get the up-and-coming ones as well."
