Introduction to
Sustainable and Impact Investing

Thursday 8 June 2023
15:30 - 17:00 CET (Online)

This workshop is intended for accredited investors*.

During this 1,5 hour online interactive session, you will be introduced to the basics of impact investing and sustainable investments, and how they can be applied to your own impact journey. 

We discuss how to define impact and the various impact themes, how you can have an impact through all asset classes, and how the ecosystem works.


Nathalie Nebelius

Membership Engagement Manager of Toniic Europe, who has been a facilitator of impact investing for almost a decade

Veerle Berbers

Co-founder of PYM and Impact Investor for nearly 2 decades.

The format will be interactive, with plenary presentations and small break-out sessions for discussions among the participants.

Our goal is to give you some tools and frameworks to start deploying your wealth in alignment with your values. On top of that, experienced impact investors Siemon & Willemijn will give you an insight into their personal portfolios, providing you with examples of how to get started.


Siemon is an entrepreneur who started his first business while he was still in high school. After twenty years of starting and scaling up IT companies, he diverted his attention to impact investing. Siemon is experienced in impact private equity funds, impact mandates for listed equities, direct impact investments, and direct impact grants.
Siemon is passionate about fighting climate change through innovative startups and NGOs. He is a member of several Dutch and international impact investing communities.


Willemijn is a pedagogue with a passion for generating social impact in her immediate environment. She works for Humanitas, a Dutch NGO that supports people who need temporary help. She wants to drive change in the world through sustainable and social investments.

Willemijn and her husband started an ophthalmology company in the Netherlands. After selling the company, they started investing more and more in financial inclusion in Africa, Latin America and Asia. Besides that, they also focus on climate technology in various sectors and have invested in carefully selected listed securities that generate impact.
