I have personal experience with university endowments, and at some point noticed that the open source world is remarkably similar to a top research university. They share the same reputation-based culture and functions — collaborative creation of IP as a public good, educating each other within thematic clusters, and commercializing only a small fraction of what they produce.
For universities, humanity has just two sustainable funding models: public spending or private endowments. Government support won't work for OSS at scale — it's too globally decentralized. And yet nobody had built an OSS-focused endowment before. After understanding why, I started building one together with other OSS folks.
Today we're publicly launching the Open Source Endowment — a community-driven endowment fund dedicated to sustainably funding maintainers of the most critical open source projects. All donations are invested in a low-risk portfolio, and only the investment income (~5%/year) is used for grants, making it independent of annual budgets and tech market volatility.
We recently received US 501(c)(3) tax-exempt charity status. The fund is at ~$700K, formed by 60+ founding donors — including founders of HashiCorp, Elastic, ClickHouse, Supabase, Vue.js, Pydantic, Nginx, Gatsby, n8n, and curl. Everyone is welcome to join them and participate in governance.
There's no perfect model for distributing OSS grants. Our approach: make it open, data-driven, measurable, and developed by people with skin in the game — donors. I tested this by personally donating $5K to 800+ Python projects in Dec 2024 (https://news.ycombinator.com/item?id=42312469). We're now looking to grow our donor community and together finalize the first model for grants in Q2 2026.
This is a pure community charity, and there are two things I'd love from HN:
1) Join as a donor — any amount — and help make OSE the most efficient long-term funding solution for OSS maintainers
2) Nominate OSS projects you think are critically underfunded on the Funding page at endowment.dev
