Grants data from ca. 600+ funders worldwide is provided directly by funders themselves or from public sources. Funding data often comes directly from the funder organisation, especially where funders are Dimensions partners, and this is provided in a variety of different ways depending on the funders preference. New grant sources are added on a regular basis, as well as existing funder sources being updated when new data is available. An up-to-date list of data sources is provided here: https://app.dimensions.ai/datasources (subscription required to access this page).
