The Fellowship

Future Climate Leaders

Solving planetary challenges requires not just breakthrough technology but the talented, multidisciplinary leaders capable of bringing those technologies to scale. This 12-week summer fellowship places early-career professionals at the heart of the climate tech ecosystem.

Direct startup engagement
Fellows work directly with climate founders on real challenge, from fundraising strategy and market entry to research and ecosystem development. They don't observe. They contribute.
Multidisciplinary perspective

Through immersion across nonprofit, startup, and research-driven innovation environments, fellows develop a rare, cross-sector understanding of what it truly takes to scale climate solutions.

Your contribution funds the company-building services and fellowship experience that fuel the development of transformative climate technology — and cultivate the leaders who will carry it forward.

Network & Mentorship

Fellows work directly with the ClimateHaven team, extensive advisor network, and founders building the future of energy, transportation, and climate resilience — relationships that last a career.

A Pipeline for Climate Leadership

Future Climate Leaders is designed to empower the brilliant students of today to become the climate leaders of tomorrow, tackling the planetary challenges that require both talent and tenacity.
