Microsoft FOSS Fund

Corporate open-source sponsorship program operated by the Microsoft Open Source Programs Office. Microsoft employees nominate and select projects; the public repository records recipient cohorts. It is not an open external grant application. Published quarterly pool figures must not be assigned to individual recipients, and a recipient listing does not establish a payment date.
