The Halcyon Global Climate Fellowship 2026 invites climate startup founders worldwide to accelerate scalable solutions for climate adaptation and resilience through funding, mentorship, and global networking.
A Global Opportunity for Climate Entrepreneurs
As climate risks intensify across regions and industries, the need for scalable, market-driven solutions has never been more urgent. In response to this growing challenge, the Halcyon Global Climate Fellowship 2026 is opening its doors to climate startup founders from around the world who are building innovative solutions for climate adaptation and resilience.
Designed specifically for for-profit ventures, the fellowship supports entrepreneurs who are moving beyond ideas and actively validating their solutions in real-world settings. With a strong emphasis on founder development, investment readiness, and long-term impact, Halcyon offers a unique platform for climate innovators seeking to scale both their businesses and their influence.
Who the Fellowship Is Designed For
The Halcyon Global Climate Fellowship targets startup founders at an early but proven stage. Eligible applicants must be CEOs or primary decision-makers of their ventures and may apply individually or with one co-founder.
Applicants are expected to demonstrate meaningful progress, including:
- A working minimum viable product (MVP)
- Early validation such as pilot projects, letters of intent (LOIs), or initial revenue
- A clear focus on climate adaptation and resilience, rather than mitigation alone
Importantly, the programme is open to founders from any country, reflecting Halcyon’s commitment to building a truly global climate innovation ecosystem.
Why Halcyon Stands Out
The Halcyon Global Climate Fellowship is more than an accelerator. It is a high-touch, founder-centric programme designed to meet entrepreneurs where they are and help them overcome the most critical barriers to scale.
Rather than focusing solely on pitch decks or short-term growth metrics, the fellowship emphasizes:
- Long-term leadership development
- Strategic clarity around product–market fit
- Capital strategy and investment preparedness
- Meaningful connections with policymakers, investors, and ecosystem leaders
By combining practical business support with access to influential networks, Halcyon enables founders to move faster while staying grounded in real climate impact.
What Selected Founders Receive
Fellows selected for the 2026 cohort gain access to a comprehensive package of financial, technical, and strategic support, all provided equity-free.
Key benefits include:
- USD $6,000 equity-free stipend per venture, allowing founders to focus fully on growth
- USD $10,000 in AWS credits to support product development and scaling
- Expert-led workshops covering product–market fit, capital strategy, leadership, and growth
- Access to professional advisors and tailored one-on-one founder support
- Two immersive, in-person residencies held in Washington, DC and Los Angeles, CA
- Curated networking opportunities with investors, policymakers, and climate stakeholders
- Lifetime access to Halcyon’s global community of more than 600 founders, along with continued post-program benefits
This combination of resources ensures that founders are not only better equipped during the programme, but also supported well beyond its conclusion.
A Truly Immersive Fellowship Experience
The fellowship runs from April to September 2026, blending virtual programming with in-person experiences. The two residencies in Washington, DC and Los Angeles are central to the programme, offering founders direct exposure to policy environments, capital markets, and diverse climate ecosystems.
These residencies are designed to foster deep collaboration among fellows while facilitating meaningful engagement with decision-makers shaping the future of climate action. The result is a cohort experience that balances peer learning, expert guidance, and real-world connection.
