Join in Live

Join in Live, operated by Buff Up Ltd., provides a branded live audience-engagement platform for broadcasters, sports rights holders, event owners, podcasters and radio networks. The platform is designed to turn passive audiences into active participants while keeping conversations, first-party audience data and commercial opportunities within the media company's own ecosystem, rather than directing viewers to third-party social platforms. The company was originally launched as Sport Buff and has since rebranded, broadening its focus from sports fan engagement to live interaction across broadcast and audio content.

The Join in Live platform lets audiences respond to predictions, polls, quizzes and ratings, join moderated group chats, climb individual or group leaderboards, and claim offers or make purchases while watching or listening. Participants join via a link or QR code with no integration changes required, and the platform supports 19 languages.

Two capabilities underpin the offer. AI question drafting uses natural language processing to generate questions in context from commentary, subtitles or live audio as an event unfolds; producers retain editorial control, approving, editing or rejecting each question, and clients may alternatively delegate live operation to the company's team. The technical stack also covers live streaming and broadcast technology, first-party audience data capture, gamification and in-experience commerce.

The company serves a range of verticals, including broadcasting, sports rights holders, live events, podcasting and radio networks. Its stated emphasis is on editorial control for producers and on retaining audience relationships and revenue opportunities within the client's own environment.
