Dear Impact Maker,
The world’s challenges are too complex for single solutions. If money alone could fix things, we wouldn’t still be here. If policy alone could change the rules, they’d already be rewritten. And if startups meeting investors were enough, the future would already look different.
Impact happens when unlikely forces collide—entrepreneurs and investors fueling bold ideas, corporate innovators and leaders dismantling old systems, policymakers driving reform, and civil society ensuring progress serves everyone.
This isn’t just another gathering—it’s where new alliances form, new ideas take root, and the future starts to take shape.
IMPACT DAYS 2025
12-13 May, Vienna City Hall
How can we create impact in a fragmented world?
Impact Days 2025 is more than a conference—it’s a movement to challenge our assumptions, expand our horizons, and redefine how we create impact in a fragmented world. By including more voices and opening our silos, we aim to uncover deeper truths and collectively chart a path toward a sustainable, equitable, and inclusive future. Together, we will navigate the complexities of our time, armed with the wisdom and strength that comes from true collaboration.
We focus on the interplay of nature, technology, and humanity.
