Global Impact Investing Network (GIIN)
The Global Impact Investing Network (GIIN) is set to host its flagship Impact Forum 2025 in Berlin, Germany, from October 7 to 9, bringing together more than 1,600 participants from across the world.
With a focus on using capital to address today’s most urgent social and environmental challenges, the forum is expected to be one of the year’s largest convenings of the global impact investing community.
This year’s forum will address both persistent and emerging global issues, aiming to provide practical pathways for investors seeking to integrate impact into core investment strategies.
Attendees will represent a wide spectrum of sectors, asset classes, and geographies, including growing participation from emerging markets.
Participants will include institutional investors, asset managers, development finance actors, nonprofit leaders, and government representatives, as well as philanthropic stakeholders exploring mission-aligned investment models.
A Forum for the New Age of Investing
GIIN’s annual flagship forum has become a focal point for that momentum, where long-term strategies, tools, and cross-sector partnerships take shape.
The 2025 edition of the GIIN Impact Forum includes:
- Members Day on October 7 — a closed-door, half-day session reserved for GIIN members
- Main Forum on October 8–9 — open to the global community, featuring high-level plenaries, breakout workshops, networking events, and thematic deep dives
Impact investing is no longer on the sidelines. As climate shocks intensify and global inequality deepens, more capital is being steered toward solutions with measurable societal value.
Program sessions will explore how financial actors can better respond to compounding global risks while remaining accountable to measurable impact outcomes.
The agenda reflects a mix of practical tools, future-focused discussions, and real-world case studies.
Among the topics expected to shape the 2025 dialogue:
- Climate solutions, including nature-based finance models and transition-focused investments
- Resource efficiency innovations in water, waste, and energy
- Resilient agriculture systems and regenerative food value chains
- The role of artificial intelligence and systems thinking in investment decision-making
- Navigating geopolitical uncertainty through impact-aligned portfolio strategies
- The evolution of impact measurement, verification, and standard-setting
Speakers and facilitators will include leading global practitioners in sustainable finance, development economics, corporate accountability, and data analytics.
Connecting a Global Movement
The GIIN Impact Forum has steadily evolved into a central gathering point for the impact investing field, attracting participants from across the financial spectrum.
For many institutions, the forum functions as both a knowledge exchange and a strategic space to align with global peers on common challenges and innovations.
Although not designed exclusively for any one group, the forum welcomes a wide array of participants — from established financial institutions to philanthropic foundations, public sector agencies, and social enterprise enablers.
For those working to mobilize capital toward sustainable development goals, the GIIN Forum offers current, evidence-backed insight on what’s working and where innovation is needed.
Practical Engagement and Strategic Dialogue
The event’s format balances structured learning with 55+ workshop sessions planned for informal connection-building. Attendees can expect:
- Live plenaries and moderated panels on global investment trends
- Skill-building workshops focused on tools and data for managing impact
- Sector-specific sessions on infrastructure, healthcare, climate, and technology
- Curated networking spaces for fund managers, asset owners, and catalytic capital providers
- A “marketplace” to explore products and partnerships within the impact investing field
By centering measurable results and practical frameworks, the forum aims to bridge the gap between impact ambition and execution.
Institutions at all stages — whether launching a first-time impact fund or scaling existing strategies — are expected to find relevant entry points.
