Blisterent "is developing and publishing mobile location–based games and entertainment products to wireless carriers around the world." They have their own location application platform called LAP:
The LAP provides mobile content developers with an efficient and simple way to deliver their products to mobile operators. In turn, the mobile operators now have access to a location platform that can help expand their product offering to customers by increasing data traffic on their networks. The LAP provides these companies with new technology and more product distribution channels.
