Signals of Lasting Change: The Role of Venture Building in Systems Change
1
8:00 AM - 9:15 AM
Enviu just launched its 2025 impact report. As an impact driven venture building studio, it is crucial to monitor the impact we make across our ventures and programs in the domains of Agrifood, Textiles and Zero Waste. We want to share our insights and learnings and have an open conversation about creating lasting change.
What to expect from this webinar
A live session unpacking the signals of systemic change behind Enviu's 2025 Impact Report — and an honest conversation about what role venture building actually plays in shifting whole systems.
During this webinar you can expect:
Snapshot of 2025 Impact
We open with the results. Enviu walks you through how our impact grew across agrifood, textiles and zero waste compared to last year — and the four signals that tell us deeper system change is starting to move. We zoom in on the zero waste ecosystem as a live case.
Panel Discussion
Then the real conversation. A panel of funders, researchers and venture builders reflects on what systemic change looks like in practice. Where venture building has influence, where it doesn't, and what it takes to set lasting change in motion. With Tamar Matalon (Flotilla Foundation), Sherry Zhang (MIT Sloan), Denis Karema (SokoFresh) and Dieuwertje Nelissen (Enviu), moderated by Eline Leising(Enviu).
Audience Q&A
We close with an open floor. Bring your questions, push back on the thinking, and shape the discussion directly with our speakers.
Who is this for?
Funders, impact investors, execution and knowledge partners, DFIs, development agencies and government partners. Really anyone working to turn one-off wins into lasting change. Come curious. Leave with sharper insights.
