Lacuna Fund

Lacuna Fund is a multi-funder, multi-stakeholder collaboration formed in 2020 to fill gaps in the data used to train machine learning models, making ML and AI more representative, accurate, equitable, and accessible to underserved communities. It has enabled the creation of over 75 new ML datasets in agriculture, climate, health, and low-resource languages via requests for proposals. In July 2025 it announced the transfer of its leadership and management to partner institutions in Africa and Latin America.¹
