Keith Harrison-Broninski FRSA is a technologist, author, and keynote speaker. "Human Interactions" (2005) set out the world’s first formal model of collaborative work. "Set to produce the first fundamental advances in personal productivity since the arrival of the spreadsheet" (Information Age). Keith went on to lead social enterprises that developed award-winning Web platforms for national healthcare innovation and wellness. “Supercommunities” (2021) extended his model of collaborative work into a complete socio-economic design for antifragile communities. “Read this book!" (Vint Cerf, from his foreword). Keith is now leading a government programme that proves the concept. Keith’s forthcoming book “Superorganisations” will present a radical new model for social investment that throws away the rule book to enable a step change.
