Stefan Hyttfors

Stefan Hyttfors

Stefan Hyttfors is an acclaimed futurist and author focused on disruptive technologies, behavioural change, and next generation leadership. He presents on how innovation, disruptive technologies, and behavioural change affects the world.

Digitalisation and networking technologies highlight inequality as well as unsustainable consumption of resources. This is the foundation for a new economic system that will allow us to create more value with less resources to stay within the planetary means, and to meet the basic needs of every human.

We are in the beginning of a new era. The corporations, leaders and brands we will talk about in ten years time have not even begun yet and the true definition of ROI in the 21st century is ‘Risk of Ignorance’.
