Open Source Endowment

Founders

Konstantin Vinogradov

The world's first endowment fund exclusively dedicated to open source software. OSE is a US 501(c)(3) public charity that invests donations into a low-risk portfolio and distributes only investment returns as grants to maintainers of critical yet underfunded open source projects globally. The organization uses a data-driven Value-Risk framework to support foundational infrastructure like libraries, language runtimes, and networking tools, with the first grant round planned for Q2 2026.
