The Thinkers50 Speakers

The Thinkers50, is the premier ranking of the top global business, management, strategy and leadership thinkers whose ideas have the potential to change the world. With a potential impact that extends far beyond the business arena to address issues ranging from reducing poverty to building a sustainable model of capitalism, The Thinkers50 has ten established criteria by which thinkers are evaluated: originality of ideas; practicality of ideas; presentation style; written communication; loyalty of followers; business sense; international outlook; rigor of research; impact of ideas and the elusive guru factor. BigSpeak is proud to represent these renowned Thinkers50 speakers, authors and thought leaders and deliver their vanguard leadership and management programs, groundbreaking ideas and dynamic presentations to our clients.
