Join In Live (formerly Sport Buff) provides an interactive layer for live and on-demand video, enabling broadcasters, leagues and platforms to add real-time quizzes, polls, predictions and games on top of their content. It also offers a companion “second-screen” mode so fans can join in live with events they are watching on TV. The company helps partners increase engagement and retention, attract and understand younger audiences, and unlock new sponsorship and data-driven revenue opportunities across broadcast, streaming and in-venue experiences.
