Space and People told Event it could not disclose which brands have signed up for packages.
Fusion, which made its debut last year, will be held in Cofton Park on Saturday 20 and Sunday 31 August.
More than 60,000 revellers are expected to attend the event, which will feature urban pop artistes such as Pitbull, Jessie J and Dizzee Rascal.
Space and People is offering various packages to brands. Full media and sponsor partnerships are also available, offering companies on-site branding, pre-event, artist-led social media interaction, experiential spaces of up to 20 metres by 20 metres and fully-tailored activation production during and after the festival.
Nick Hill, sales director of Space and People, said: "We are very excited about the new partnership with Miles and the potential the event offers.
"The Fusion Festival provides a fantastic opportunity for brands to engage with 16-24 year olds and their parents in the build up to and during the event. The festival offers a unique platform for experiential and promotional activity and is an ideal way to differentiate a brand for its competitors."
Damien Sanders, Fusion’s festival director, added: "We are delighted at this new partnership. Fusion is only in its second year and has already grown to become one of the most talked about pop events of the year.
"We’ve got some great additions to the line-up still to announce and one or two that really are something special. It’s an exciting time."
