About Plumzi: Plumzi is enabling the future of TV by giving studios a third storytelling dimension – “participation” – to leverage in their creative process, in addition to traditional pictures and sound dimensions from linear TV. Plumzi’s platform allows studios and creators to author and stream interactive “appisodes,” a new form of entertainment on tablets, smartphones, smart-TVs, and – soon – Virtual Reality headsets. Appisodes enable viewers to interact with characters and help drive the story via touch, voice, tilt, connected toys, motion-enabled remotes, and more. The world’s leading animation studios – including Nickelodeon, Cartoon Network, DreamWorks, Warner Bros., Saban Brands, American Greetings, and others – already rely on Plumzi’s technology platform to not only adapt and monetize their animated series as appisodes, but also to expand their new show narratives beyond linear TV with a native appisode component. Plumzi is headquartered in Palo Alto, CA, and funded by Silicon Valley VCs, along with strategic investors including The Walt Disney Company, Turner Broadcasting, Fuji TV, KDDI, and prominent angels like Bobby Yazdani (early investor in Google, DropBox, Uber, etc), Eric Kessler (former HBO president), and Stu Snyder (former Cartoon Network president). Plumzi is a winner of Disney's 2012 Innovation Challenge and a 2013 graduate of Media Camp, the accelerator program by Turner Broadcasting and Warner Bros.
