Society3.0 smart, sharing & simple


Welcome to the future of today, the world of Society30. A movement. A change agent in our turbulant world.

More practical: Society30 is also a foundation and a publishing company.

Society30, its activities, its books and publications, its events and this website are the visualization of the shared mission of
CDEF Holding BV, a disruptive business concept explorer, started in 2003 by Marielle Sijgers and Ronald van den Hoff.

A vision. A search. A roadmap to the new world. SOCIETY30.

"A new order is presenting itself. It may still be an undercurrent, but maybe that is the best way to grow. We see more and more people who have clearly chosen how they want to go about with themselves, their environment and other people.

They are the people we call global citizens: people of the new world. These Society30 citizens cannot and will not deal with the thinking of the establishment anymore. They want to add value in their work and life in a significantly different way, namely by creating value instead of growth.

We think these global citizens – who are increasing in number daily – are the pillars, which support Society30. Hundreds of millions of people of the world move around without restraints, literally unbounded, across borders all over our world. Sometimes they do this physically, but more often they do so digitally through out the Internet: the World Wide Web. These people of the world are no longer bound to old organizations. They have organized themselves in virtual social networks. They have started to create value in a different way. They do not work according to a formal organizational structure. They guide themselves. They are themselves. Their social connections show great creative vitality and unleash an enormous amount of energy. From within their self-awareness they respect the individuality of anybody. People of the world of Society30 are not after personal enrichment at the expense of others. They share; they are prepared to do a lot for someone else, without always expecting a monetary reward. They reinvent society and create all kind of new, fair and sustainable business models.

We think it is both exciting and fun to be such a person, a Knowmad of the world of Society 3.0."
