Diane Hamilton

Founder and CEO of Tonerra, a US-based leadership and management consulting company.


Thinkers50 Radar Class of 2020.


The first person to create a valid assessment that determines the factors that inhibit curiosity.


Named to Global Leaders Today’s list of top leaders along with Elon Musk, Jeff Bezos, Richard Branson, and Sheryl Sandberg.


In her book, Cracking the Curiosity Code, Hamilton uncovers what could foreseeably be the next movement to enhance human performance, a critical and direct link to improving motivation and communication-based issues that challenge organizations. Drawing on decades of research and incorporating interviews from some of the top leaders of our time, Hamilton examines the factors that influence curiosity including fear, assumptions, technology, and environment (FATE). Her ground-breaking research provides an action plan to transform individuals and organizations. The organization that can stimulate its workers’ curiosity, she argues, can enhance employee engagement, emotional intelligence, innovation, and other critical factors that impact innovation.

She has authored multiple books which are required in universities around the world, including Cracking the Curiosity Code and The Power of Perception. She is the creator of the Curiosity Code Index® assessment, which is the first and only assessment that determines the factors that inhibit curiosity, and the Perception Power Index, which determines the factors that impact the perception process. Hamilton is listed by LeadersHum in their 200 Biggest Voices in Leadership and in their Top 10 Most Powerful Women Leaders in HR.
