He was the founder of SBTV, an online urban music platform which helped launch the careers of artists like Dave, Ed Sheeran and Jessie J.
Chart-topper AJ Tracey was one of the first to pay tribute online, tweeting “RIP Jamal Edwards, west London legend status”.
Edwards, born in Luton, was appointed an MBE for services to music in 2014.
He also became an ambassador for the Prince’s Trust, a youth charity run by the Prince of Wales which helps young people set up their own firms.
Edwards, who was the son of singer and Loose Women presenter Brenda Edwards, first got into film-making after his parents gave him a video camera as a Christmas present when he was 15.
In a 2013 interview, he said he filmed friends rapping or singing and began to upload the videos to YouTube to allow other friends to see them.
“You can say my videos had mixed reviews to begin with, some people didn’t get them, but others thought they were sick [good],” he said. “So I started to put them up on YouTube so everyone could see them, and it just grew from there.”
Chelsea legend John Terry posted online: “RIP my friend.”
Vauxhall MP Florence Eshalomi added: “Very sad hearing this loss. To have made such an impact at such a young age. Rest in peace Jamal Edwards.”
Rapper Dave, who was due to perform at the O2 arena this week, posted: “Thank you for everything. Words can’t explain.”
