Yospace

Leading specialist provider of server-side ad insertion technology for live and on-demand video streaming, trusted by major broadcasters and OTT operators globally

Founded in 1999, Yospace is a UK-based technology company specialising in server-side ad insertion (SSAI) for live and video-on-demand streaming. Its platform enables broadcasters, pay-TV operators, and OTT service providers to dynamically replace or insert targeted advertising into video streams at the server level, eliminating the buffering and user experience issues associated with client-side ad insertion. Yospace's technology is designed to be indistinguishable from traditional broadcast advertising, delivering frame-accurate ad stitching at scale. Yospace serves some of the world's largest media companies, including major broadcasters and streaming platforms, providing the infrastructure that allows them to monetise live and on-demand content through programmatic and direct-sold advertising. Its platform integrates with leading ad servers, demand-side platforms, and content delivery networks, making it a critical middleware layer in the streaming advertising ecosystem. The company is particularly well regarded for its handling of live streaming ad insertion, a technically complex challenge that few vendors address at broadcast scale. Yospace was acquired by TransUnion in 2021 as part of that company's expansion into streaming media and identity-driven advertising solutions, though it continues to operate as a distinct entity within that portfolio. Its competitive advantages include deep broadcast heritage, proven reliability at high concurrency, and strong relationships with tier-one media rights holders and broadcasters globally.
