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

I’m curious… would you consider having a “faculty” of “tenured” maintainers who receive livable funding and support based on a history of significant contribution? I could imagine something like “named chairs” and professorships you see for some tenured folks in academia. This could be useful for key project leaders, and contributors. In addition, any kind of function to train and develop the next generation of maintainers?

A way something like this could be interesting is if founders started donating 5% of equity when they started a company to an open source foundation like this one.

It doesn't impact the founder much financially: Success is very binary for founders. But in aggregate, if thousands of startup founders do this, there would be some hits and some of those hits could generate a significant endowment.

(You can also try to get people to donate who feel their success was built on top of open source, but I feel that after 10 years building a company to IPO, one's attention as a founder has likely been on business metrics and spending time with business people, not on technology and spending time with technologists, and that shift in attention can reduce people's feeling of gratitude for the amazing inheritance that is open-source software).

Plus, OS maintainers now have to deal with agents and vibe coders who can commit plausibly-looking code that doesn't actually do what it's supposed to, so the volume of work for them is only growing.

In a different world we would incentivize tech giants to sponsor critical open source projects by turning their donations into more serious tax write offs, up to a certain amount, and reviewed by experts within the industry, affiliated and unaffiliated with the companies doing the funding.

The organization needs a way to make something valuable it can charge a (membership) fee for, not just collect donations. Then it can share some of those fees with its developer-contributors, byt distributing a dividend that goes on to prepetuity instead of individual one-time grants.

So, two types of members, contributor-developers, and code-using organizations which get a less restrictive license.

This seems like a chicken-and-egg problem, but once it starts going it could be sustainable.

Just another Silicon Valley bro that wants to be in-charge of something with zero democratic control. Very typical in the current environment, which is why it should be soundly rejected.

I remember being so frustrated with why people aren't using Open source that I created a Ask HN about it [https://news.ycombinator.com/item?id=45558430] (Ask HN: Why are most people not interested in FOSS/OSS and can we change that)

The answer was a bit of chicken and egg problem. For end users, Open source feels second to good UI/UX but for developers who are severely underfunded, UI/UX isn't that much of a concern.

It was also a chicken and egg problem of funding itself, the above problem could've been solved if people could fund developers for better UI/UX or QOL features and then these services can be made better and people could use them de-facto and donate them further.

The issue at the time to me felt like as such, the biggest problem holding Open Source back was its lack of funding. This idea captured my mind so much so that I may or may not have a FOSS manifesto in one of my files after thinking about it for many many days ;)

This seems to be doing something new for Open source. I always preferred Nlnet in such situations but Nlnet is a single donation model whereas this is an endowment model.

I really appreciate the author for creating it as its truly something new for Open source and something which I do feel like is a worthy experiment and I wish this project success to have meaningful impact on the massive funding problem of Open source itself hopefully.

I actually thought of something here but for countries who have sovereign wealth funds, perhaps one can argue that a tiny backdrop of that amount driven into some project like this could do wonders for data sovereignity itself and prevent lock-ins of PSU's if say especially more funding could be given to all Microsoft alternatives as I see online that Microsoft is one of the worst offenders of lock-in for govt.s where If I remember correctly, there were definitely billions of dollars involved (iirc, I could be wrong tho)

I genuinely wish this project massive success for its future. I do think that there are some gotchas within this though (like how are you gonna give the money to contributors and get the money to the contributor who lives in nevada from the infamous xkcd) but I can only hope that given they have built this, they are passionate about the problems with open source and would figure out gotchas (I hope sooner than later)

Also if I may ask if you ever might need any volunteer for the project itself [I would prefer some minimal payment (just enough to pay rent haha) in the spirit of the project itself] then please reach out to me from mail when there might be such need.

Side note but I also believe that one of the ideas I wish to suggest if possible is a side-branch of the endowment which can help non-profits to move from their locked-in solutions to open source solution / self-hosted and have them donate some money instead of paying to the locked-in solutions, but rather paying to the endowment fund itself.

I think you can also combine this with some providers who might wish to donate their hardware resources as well for free (Hetzner/OVH and many other Lowendtalk providers) for perhaps some good-will/some more attention to their company in the cutthroat competition.

So this can help save real money from already non-profits who have important missions and save them money for their real causes rather than hardware costs/licenses/lock-ins and they could instead spend a tiny fraction of that money to fund the project itself which could fund Open source itself as well.

This can end up being a win-win situation in my opinion.

I may be a little too excited but I do see lots of potential.

If possible, I'd love to reach out to you regarding this to have hopefully a meaningful discussion about it.

TLDR: I have also created a excalidraw diagram to better explain what I mean by the last paragraphs.
