Phase 2: Pre-Accelerator Programme

Four to five ESOs will be selected to run the Pre-Climaccelerator programme, aimed at supporting climate ventures at the pre-seed stage. This programme will help further develop their climate solutions and Minimum Viable Products (MVPs). It plans to onboard 80 ventures from the selected countries, providing them with professional resources, knowledge, and networks for a duration of six months to scale their climate solutions.

A second cohort for the pre-accelerator programme is expected in July 2024, focusing on new climate innovations.



Ongoing: Accelerator Programme

Over a span of three years, it will scale up to 30 ventures, ensuring they are well-positioned for growth and market impact. This initiative operates on a rolling basis, allowing for continuous intake and support of ventures as they reach pivotal stages in their development.
