Cada día es una fiesta!

CDEF Holding

The abbreviation C.D.E.F. is Spanish for ‘Cada día es una fiesta’: everyday should be a celebration! This credo requires an attitude to start everyday with a healthy dose of playful curiosity. This in turn, gives our stakeholders and us the opportunity to do the things we enjoy doing. And working with pleasure means following your passion and creating space for innovation.

Our vision and mission is written down in the book Society 3.0, published in Dutch in April 2011 and in Spring 2014 the English and updated version was be published.

Marielle Sijgers & Ronald van den Hoff

We are the co-founders of CDEF Holding BV, a Holding company with a remarkable range of ventures operating on the disruptive intersection of the Hospitality Industry and the entrepreneurial world of Internet.

CDEF incorporates ‘much discussed’, disruptive exponential formulas, like the co-working and meeting centers Seats2meet.com and the Society 3.0 Foundation.

Seats2meet.com, with 205 locations in 29 countries worldwide, has become an interactive breeding ground for inspiration, innovation, entrepreneurship acceleration, cross-linking and cross-pollination. We are not only creating our in-house software and apps, but also intelligent self-learning software like ‘The Serendipity Machine’. S2M collaborates within a network of global IT experts.

A publishing company, The Society 3.0 Foundation, completes this range of innovative ventures. In April 2011 this Society 3.0 Foundation published Ronald’s book Society 3.0, creating a context for all CDEF’s activities. This Society 3.0 foundation is a movement, a guiding light and a change agent in our ever-dynamic world. Its activities, books, publications, events and
websites are the visualization and exploration of the vision and mission of the CDEF Holding.
