Chartboost is a San Francisco-based mobile game discovery and monetization platform. The company, which acts as a business engine for mobile games, allows video game developers to create customized interstitial and video ads, promote new games, and swap traffic with one another. Developers have direct access to game data derived from Chartboost-enabled games. As of 2016, Chartboost had been integrated into more than 300,000 games with 40 billion game sessions per month. The company has raised $21 million in funding and has offices in San Francisco and Amsterdam. Game developers use the Chartboost mobile platform to design custom interstitial and video advertisements, build user bases, generate revenue, negotiate business deals with other developers, as well as track and analyze sales and promotion data. Chartboost’s cross-promotion product allows developers to show promotions for a new game to players in their other games, allowing them to leverage their own portfolio of engaged players to support a successful launch.
