Keith leads the Greenlight Research Institute, which conducts studies on team transformation and the future of work. He is a champion of ‘teamship’ – a reimagining of how teams operate and collaborate, shifting from traditional hierarchical leadership to a peer-to-peer model of co-leading and co-elevating. Keith also advocates for a peer-powered approach to implement AI at scale, based on a grassroots methodology. As the creator of the Radical Innovators Collaborative, he brings together disruptive thinkers to accelerate organisational transformation.
Founder and CEO of Ferrazzi Greenlight, Keith has coached the transformation of Fortune 500 corporations, the World Bank, fast growth Unicorns, and governments. He is a business coach who challenges the way teams work to achieve breakthrough results through more connection and collaboration across silos, shifting from leadership to teamship. Keith’s work has been published widely, including in the Harvard Business Review, Wall Street Journal, and Fortune.
