Chartboost is a leading in-app programmatic advertising and monetization platform that enables mobile app developers, particularly in gaming, to generate revenue through customized interstitial and video ads while connecting advertisers to global in-app inventory.[1][2][3] Its SDK, one of the most widely integrated independent mobile ad SDKs, reaches over 700 million unique users monthly across more than 200,000 apps, serving top iOS and Android developers by solving monetization challenges in a competitive mobile ecosystem.[2][3] Acquired by Zynga for $250 million in 2021 and sold to AI-powered adtech firm LoopMe in December 2024, Chartboost demonstrates strong growth momentum, with past rankings like 6th on Android ROI in 2019 and recognition as a top media source by Kochava, Appsflyer, and Singular.[1][2]
Chartboost was founded in 2011 in San Francisco by Maria Alegre (co-founder) and Sean Fannan (CTO), who left Tapulous to build a self-developed platform giving game developers full transparency and control over promotion, sales, revenue, and management of mobile games.[1][4] The first product, Cross Promotion, launched that year, followed by rapid expansion including a $19 million Series B round led by Sequoia Capital in January 2013 and the opening of an Amsterdam office in April 2013.[1] Key early team members brought expertise in data science, product management, engineering, and more, driving initial traction to over 300,000 integrated games by 2016.[1][2] Pivotal moments included the 2016 acquisition of Roostr (later shut down as Chartboost Influence), Zynga's $250 million buyout in 2021, and LoopMe's acquisition in late 2024.[1]
Chartboost rides the explosive growth of mobile gaming and in-app advertising, where programmatic platforms bridge developers' monetization needs with advertisers' demand for targeted, high-engagement inventory amid rising app usage.[2][3] Its timing capitalized on the post-2011 mobile app boom, scaling via cross-promotion innovations when direct developer control was scarce, influencing the ecosystem by setting standards for SDK integration and transparency—now amplified by AI trends via LoopMe.[1][2] Market forces like adtech consolidation (Zynga/LoopMe deals) and data-driven targeting favor its position, as it connects the majority of top-grossing apps to brands, boosting overall mobile revenue models.[1][3]
Under LoopMe, Chartboost is poised to leverage AI for outcomes-based advertising, enhancing personalization and ROI in gaming/mobile amid surging demand for intelligent marketplaces.[1][2] Trends like AI ad optimization and privacy-focused targeting will shape its path, potentially expanding beyond gaming into broader app verticals. Its influence may evolve from pure monetization enabler to AI-powered ecosystem leader, building on a decade of acquisitions and scale to redefine in-app revenue in a maturing adtech landscape—echoing its origins as a developer-first disruptor.
Chartboost has raised $40.0M across 3 funding rounds. Most recently, it raised $19.0M Other Equity in January 2013.
