Chartboost

One of the most established mobile in-app advertising and mediation platforms, with deep penetration in the mobile gaming vertical and a large direct SDK footprint

Acquired by LoopMe in December 2024, Chartboost is a mobile advertising and monetization platform that has long been a cornerstone of the in-app advertising ecosystem, particularly within mobile gaming. Founded in 2011 and headquartered in San Francisco, the company provides app developers and publishers with tools to monetize their applications through interstitial ads, rewarded video, and programmatic demand, while also enabling advertisers to reach highly engaged mobile gaming audiences at scale. The acquisition by LoopMe — a UK-based AI-powered advertising platform — marked the end of Chartboost's tenure as a Zynga subsidiary, a relationship that began when Zynga acquired the company in 2021. Chartboost's core offerings include its Mediation platform, which allows publishers to manage multiple ad networks and maximize fill rates and eCPMs, as well as its DSP (Demand-Side Platform), which gives advertisers programmatic access to premium in-app inventory. The platform is deeply integrated into the mobile gaming supply chain, with direct SDK relationships across thousands of apps, giving it a distinctive first-party data advantage and direct path to in-app inventory that attracted LoopMe's interest. In the broader AdTech ecosystem, Chartboost occupies a well-established niche at the intersection of mobile gaming, programmatic advertising, and app monetization. Its transition to LoopMe is expected to enhance its capabilities with AI-driven audience intelligence and brand advertising solutions, complementing Chartboost's existing performance-focused heritage. The platform continues to serve mobile game developers, independent app publishers, and performance advertisers seeking efficient, direct access to engaged mobile audiences.
