Mezzo is a platform that maps the global conference-speaking landscape, helping event planners, researchers, and speakers explore who presents, where they speak, and what topics they cover. It indexes more than 9,300 speakers, 3,600 conferences, and 19,700 talks, drawing on events such as TED, Web Summit, SXSW, Cannes Lions, and CES.

Users can search speaker profiles, browse conference lineups, and discover speakers by topic or curated expertise collections. Profiles bring together speaking histories, event appearances, subject areas, and available talk recordings, while conference listings make it easier to review past programs and follow current speaker circuits. Mezzo also offers full-length conference sessions, typically 30 to 60 minutes, rather than short highlight clips.

For speakers, the platform compiles public speaking histories and provides an option to claim a profile, verify it, and add information. For event planners and curators, Mezzo supports candidate research with gig histories, talks, stage connections, and verified contact information. Its collections span areas including leadership, climate and sustainability, the future of work, inclusion, and technology.
