I'd say, different event = different sponsors. And most of the time, freestyle is just a part of some event, used for entertainment, like for example dancers. The only freestyle events right now are freestyle competitions and freestyle clinic (mostly in Holland). And those are sponsored mostly by some freestyle company like SSD, Komball, Teco7 (Eurobac), etc.
Also, events regarding freestyle football are sponsored by sports equipment companies - Adidas, Nike, Monta, etc., beverage and food companies - Red Bull, Pepsi, Pringles, Carlsberg, etc.
