Chartboost is a San Francisco-based mobile game in-app programmatic advertising and monetization platform. Chartboost SDK enables developers to monetize on their mobile apps and connect advertisers to global in-app inventory. Chartboost's platform allows video game developers to create customized interstitial and video ads to promote new games. 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. In 2019, Chartboost has been ranked on a return on investment index and it scored 6th position on Android and 14th on iOS, on both platforms appearing behind mobile ad networks by Google, Facebook, Unity Technologies, Aarki and Vungle. In 2020 and 2021, Chartboost on Android is not on the list of the top 20 ad networks. On the iOS side, there is uncertainty as well due to new platform restrictions about advertising ID collection which "may render Audience Network so ineffective on iOS 14 that it may not make sense to offer it" - Audience Network and Chartboost being integrated and advertising ID collection being the backbone of both (96% of US users opt-out of app tracking in iOS 14.5). In May 2021, Zynga acquired Chartboost for $250 million. Use and features 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. Game ad network Chartboost only shows promotions to active gamers. Video Featuring high-definition videos, Chartboost Video enables developers to customize the design and execution of their video ad campaigns. The service is offered in conjunction with Reward Video, which awards players with virtual currency when they opt to view an offered video. InPlay Chartboost InPlay is a customizable, interactive advertisement layer that allows developers to create promotions which display directly in a player's gameplay environment. InPlay is intended to create promotions that integrate with the look and feel of a particular game. The native advertising solution supports standard Chartboost features such as tracking and reporting, player targeting, and cost per impression maximization. Insights Every month, Chartboost releases a global heat map that details the average cost per install on iOS and Android devices.
