Caribbean Climate Pre-Accelerator (2026)

In partnership with the Hazelwood Network, Halcyon’s Caribbean Climate Pre-Accelerator will support early-stage climate founders across the region. This six-month pre-accelerator is designed to catalyze climate innovation, target regional challenges, and support proximate founders that have been previously underserved. The program will focus on internationalization, global connectivity, and capital readiness, leveraging Halcyon and the Hazelwood Network’s cross-regional networks in Latin America, Africa, and the United States.

The Pre-Accelerator is dedicated to the architects of Caribbean resilience: those creating the infrastructure, food systems, and tools that allow the region to not only survive the climate crisis, but to lead the world in adaptation solutions. Climate leaders building practical, scalable solutions that help Caribbean communities prepare for, withstand, and recover from climate impacts are encouraged to apply. Also encouraged are service-based models, community enterprises, and tech and blended solutions.

Through a hybrid programming format, selected entrepreneurs will attend a one-week, in-person residency in Kingston, Jamaica, five virtual programming days, and a final half-week, in-person residency in Bridgetown, Barbados.
