Bidstack Group Plc announced an exclusive partnership with Belgrade-based Nordeus, best known for its game, Top Eleven, which is now part of Nasdaq listed Take-Two Interactive Software Inc. Top Eleven was first released in 2010 and is now one of the longest running mobile games as it celebrated its eleventh birthday this year. According to AppAnnie, based upon downloads and revenue to April 2021, Top Eleven is the world's most successful mobile football management game with more than 240 million registered users, and is available to play online, as well as both iOS and Android. Top Eleven allows gamers to play in a single-player mode, with friends or to take on other managers from around the world in real-time. The iconic football manager Jose Mourinho became the official face of the game in 2013 and players are able to take on his hints and tips. This new partnership bolsters Bidstack's stadium vertical, which is a natural environment lending itself well to native in-game advertising. The deal demonstrates the progress the business has made in working with the game developers. The integration of Bidstack's proprietary technology into the Nordeus game is intended to increase success of the game by enriching data and reporting.
