Impact Cities: Building Thriving Ecosystems for Innovation & Sustainability

Cities are at the forefront of building impact ecosystems and tackling global challenges -  from climate resilience and economic inclusion to fostering innovation and entrepreneurship. But what does it take to create a thriving impact-driven ecosystem where entrepreneurs, businesses, investors and policymakers collaborate effectively? This session explores how cities can serve as catalysts for systemic change, using case studies from Hamburg and Vienna - leading urban centers in Europe.

  • How municipal leadership can drive social innovation and sustainability.

  • Public-private partnerships, community engagement, and policy frameworks that create fertile ground for impact.

  • Deep dive into the flourishing impact ecosystems of Hamburg and Vienna.

  • Lessons in creating replicable urban impact models.

Investors: Discover urban-led initiatives creating investment-ready opportunities in sustainability and tech.
Leaders (Business, NGO, Public Sector): Explore how policies and partnerships can drive inclusive, long-term impact.
