Takeover Roc Nation will deal with management, merchandise, records and live shows - records will be released through Sony and partner with Live Nation for everything else - and will enable artists signed to the group to profit from collaborations with talent on Jay-Z's Roc Nation and Star Roc ventures in the US.
The company will be co-owned by Stryder and his management team, Archie Lamb and Jack Foster, along with Jay-Z and Roc Nation owners Jay Brown, John Mineilly and Tyran "TyTy" Smith.
"Jay-Z told us the reason he wanted to work with Tinchy was because he reminded him of himself when he started out," says Lamb.
"There are already a number of projects which are under way and we are currently looking at signing a number of artists."
He adds the deal will allow his artists access to writers such as Stargate, who also have a joint venture with Jay-Z through Star Roc, as well as Roc Nation talent including Rita Ora, Lil Kim, J Cole and Alexis Jordan.
Lamb says working alongside Jay-Z will help to boost Stryder's profile "not only as an artist but as a businessman".
He says, "This venture really opens up so many doors for all our artists and producers, it's fantastic. We are already in talks about some of our artists going to America for collaborations and are looking to expand as aggressively as possible."
Stryder, Lamb and Foster also run a clothing line, Star In The Hood, and own a publishing company, Takeover/Cloud 9 - which is run through EMI Publishing.
