Lockerdome

Mid-tier native advertising platform focused on sports and entertainment content

LockerDome was a St. Louis-based social content platform and native advertising network founded in 2010. The company operated a content discovery platform that enabled publishers to create engaging, mobile-optimized content experiences while providing advertisers with native advertising opportunities across a network of sports, entertainment, and lifestyle content. LockerDome's platform featured interactive content formats including polls, quizzes, and galleries that drove user engagement and social sharing. In 2018, LockerDome was acquired by The Arena Group (formerly known as Maven), a digital media and technology company. Following the acquisition, LockerDome's technology and team were integrated into The Arena Group's broader publisher platform and advertising network. The LockerDome brand gradually ceased to operate as a distinct entity as its capabilities were absorbed into The Arena Group's unified platform for sports and entertainment publishers. At its peak, LockerDome had built a significant network of content creators and publishers, particularly in the sports vertical, and claimed to reach tens of millions of users monthly. The company had raised approximately $20 million in venture funding before its acquisition, positioning itself as an innovative player in the native advertising and social content space during the mid-2010s.
