The Pydantic Open Source Fund

Pydantic emphasizes its commitment to supporting the open-source community by pledging to invest at least $2,000 per developer annually in open-source projects and maintainers, with a current annual investment of $22,000 for its 11 developers. The company spends significant resources on developing open-source libraries such as Pydantic, pydantic-core, Jiter, and FastUI, and aims to transform open-source maintenance into a financially viable endeavor. They prioritize funding projects critical to their commercial and open-source products, emphasizing the need for greater financial support in the software supply chain. This commitment, they argue, is crucial for the sustainability and advancement of open-source projects, which they believe have been undervalued despite their significant contributions to technological progress. Pydantic is also actively sponsoring a variety of projects and maintainers, such as the Official Rust implementation of Apache Arrow and other notable software tools, with a total funding of $24,000 this year.
