These guys were so minor you probably haven't heard of them anyway. BetBull, based in Gibraltar, and part of the Global network (which Betdaq is the main partner of). They promised a lot when they started on their own about five years ago, but soon realised it was an impossible task to get any decent volume and linked into the Global Sports Exchange network. From CasinoCity article As reported by Gaming Intelligence: "Betbull Holdings SE has this morning confirmed the closure of its betting exchange platform at Betbull.com, with effect from February 28th 2009. This follows the recent closure of its German-facing betting exchange platform Betbull.de late last year, prior to the enforcement of the German State Treaty on Gaming on January 1st 2009. These guys mostly focused on Germany and Spain where shops are profitable and exchange betting is simply too niche to make an imprint of the global penetration of Betfair.
