Impact Days 2 & 3 April

Change is in our Choices


About Impact Days

Pymwymic is the Put Your Money Where Your Meaning is Community. A community of impact investors who want to leave a positive footprint in this world. Since 2011, we have been organising an annual conference to share insights, inspiration and knowledge about building a new economy that serves people and planet. Two days of reconnecting and meeting new people. Impact Days is part of the non-profit activities of Pymwymic to catalyse the movement of impact investing to contribute to a restorative, healthy economy.

A special edition celebrating 25 years: Change is in our Choices

In 1994 a small group of pioneer investors looked in the mirror. They wondered why on the one hand they were focused on profit and on the other on improving conditions for people and planet. They decided to challenge the system, themselves and each other by putting their money where their meaning is. This is how Pymwymic was born. 

Today, 25 years later, we again want to challenge ourselves: are we living up to our values? We again want to take a close look in the mirror and ask ourselves: are we making the choices that will lead us to a better future? We want to learn from the past, be honest about our current and move into the future. Will you join us?

About the Programme

The Pymwymic Impact Days traditionally consists of two days – Family Day and Impact Day – bridged by the Opening Dinner. Our official programme will be announced in the spring.

Family Day April 2nd, 09.00 – 18.00 *Sold out!

Family Day is about personal reflection, family conversations and participation. We are a ‘family of families’ and host open dialogue and peer-to-peer sharing in a trusted environment. 

Opening Dinner April 2nd, 18.00 – 22.00

What better way is there to connect and share stories than to have a dinner together? At the Opening Dinner, we invite H.R.H. Princess Mabel van Oranje and Sir Ronald Cohen who inspire us on our path in realising impact. It will be an evening of challenging our current way of thinking, sharing courageous stories and calling us to action.

Conference Day April 3rd, 09.00 – 18.00

On this day we will learn about impact investing through several sessions and workshops, while being challenged by global change-makers to look in the mirror to become a better version of ourselves.
