In September 2024, The Carpentries submitted a proposal to the U.S. National Science Foundation (NSF) Pathways to Enable Open-Source Ecosystems (POSE) Program. This project would position The Carpentries as a leading open source ecosystem and further solidify our independence as a 501(c)(3) nonprofit organisation. Developing a proposal of this magnitude (1.5 million USD) involved a significant amount of preparation, from conceptualisation of the idea to navigating the complex submission process. It was the first time The Carpentries did it on our own, with our Associate Director, Erin Becker, leading as principal investigator.
