Jan van Betten, founder of Nudge

Jan van Betten started his career as a junior company lawyer with Philips before joining British American Tobacco. In 2005 he moved with his family to Munich to take up the role of CEO of Reed Elsevier Deutschland GmbH. Inspired by the development of a consumer platform for sustainable consumption in Germany, he started the social enterprise Nudge in the Netherlands in November 2010.

Nudge is the consumer platform for a sustainable society. Nudge connects consumers, companies, NGO’s and institutes to enable bottom-up initiatives that bring positive and durable change to our society. We aim to provide opportunities to take action that are accessible to everyone. We facilitate this through our platform and broad network.

Nudge is a social enterprise. We do business to make a change and we believe that knowledge and expertise is worth more when shared. Financial return is not our primary goal, but achieving our social mission is.

 

Rianne Hammenga, Event Manager Nudge

Driven by a wish to work for brands that add more to the world, she joined Nudge four years ago. Starting from sales and relationship management with the Friends of Nudge and partner organisations, she moved into the field of communications. In this position she enjoys the challenge to encourage people to positive behavioural change.

This year she is, for the second time, involved in the Nudge Global Impact Challenge as event manager of the Nudge Summit. With her endless energy and hands-on mentality, this role is wonderfully suited to her! Looks forward to see our joint efforts brought together in the Nudge Global Impact Challenge.

The MacGyver of sustainability
There’s a huge difference between professionals talking about change, transition and sustainability and people doing it.
Pepijn fits the last description. What describes him best is an innovative catalyst, in each part of the process. He lives and breathes sustainability, instead of talking about it. And he’ll make it happen, whatever is required.

Competences: change-thinker and do-er, creative development and implementation of transition, connecting his extensive network, concerned with details without loosing the big picture, hands-on business sense, chain analysis, communication, business- and concept development.

A transitional process is dynamic. Pepijn is agile and adaptive, changes along with the requirements. From thinking to acting, from analysing to connecting, from pinpointing the problem, to being part of the solution.
