TROPHiT provides a virtual-item marketing ecosystem for mobile games. Its solution boosts UA performance by allowing mobile game publishers and developers to distribute vouchers for any of their in-game items through existing networks, such as ad networks, DSPs, and RTB exchanges. TROPHiTs patent-pending technology turns every virtual item in a mobile game into a marketable unit which advertisers can distribute to gamers everywhere. The virtual items can be anything games have to offer, including free coins, unlocked levels, magic weapons, and more. The sense of added value that each user experiences results in a positive impact on session length, retention, and other metrics.
