Pydantic is deeply committed to open source, both in its development and through financial support. The company has pledged to invest a minimum of $2,000 USD per developer annually in open source projects, totaling $30,000 USD for its 14 developers. This funding is part of the Pydantic Open Source Fund, which aims to support critical projects and maintainers that Pydantic relies on for both its commercial and open source endeavors. Established as a side project in 2017, Pydantic has grown significantly, becoming a widely used tool among developers worldwide. The company believes that investing in the open source ecosystem is crucial, akin to historical investments in education, and highlights that a lack of financial support can stifle innovation and progress in the software industry. Pydantic's support is guided by the importance of the projects to their work, the financial need of the projects, and alignment with their values, with a total of $30,700 USD allocated to various projects and maintainers. The company advocates for a change in industry norms, urging others to invest in the open source supply chain, which they argue is essential for sustaining and advancing the software industry.
