SWEN, a mission-driven company for sustainable finance

We are joining forces to invest for Nature’s benefit. We are developing high-value solutions and working with our ecosystem to create sustainable value and ensure our shared growth.

In 2023, SWEN became a mission-driven company and embedded its commitments to the common good into its bylaws.


Our role as investors has been carefully shaped to deliver more than capital to entrepreneurs and the innovative projects they support. Sustainability issues and impact objectives not only guide all our investment decisions, they are also strong drivers of our partners’ engagement.

Our purpose: contribute our expertise to deploy innovative business models that help to build a thriving and fair economy. 

  1. Make sustainable value creation the guiding principle for all our investments. 
  2. Cultivate deep relationships of trust with our clients to maximise their engagement and value creation.
  3. Support our portfolio companies in their development and transformation. 
  4. Promote robust and ambitious practices in sustainable finance.
  5. Grow each partner in our team, and grow our team through each partner.
