Former leading mobile ad mediation platform, now defunct after acquisition by AppLovin
MoPub was a leading mobile ad serving platform and mediation solution that helped app publishers maximize their advertising revenue through real-time bidding and programmatic advertising. Founded in 2010, the company pioneered mobile ad mediation technology that allowed publishers to manage multiple ad networks through a single SDK integration. Twitter acquired MoPub in 2013 for approximately $350 million to strengthen its mobile advertising capabilities and provide a monetization solution for mobile app developers. MoPub's platform offered a comprehensive suite of tools including ad mediation, an ad exchange, and real-time bidding capabilities specifically designed for mobile app environments. The platform supported various ad formats including banner, interstitial, native, and rewarded video ads. MoPub became one of the largest mobile ad exchanges, competing directly with Google AdMob and other major players in the mobile advertising space. In 2021, Twitter sold MoPub to AppLovin for approximately $1.05 billion as part of Twitter's strategy to focus on its core products. AppLovin subsequently shut down the MoPub Marketplace in 2022 and integrated MoPub's technology and customers into its MAX mediation platform, effectively ending MoPub's independent operations.
