Over the last few years I've talked with hundreds of people in the dev community, and almost everyone shared the same concern: there's no sustainable funding for critical OSS maintenance, and without it the modern world runs on an increasingly fragile foundation.
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

If this is successful in the first iteration, I'd love to see a UK and EU based charities too. That would allow european donors to support on a gross pay basis, and may simplify grants to european nationals too. (I'm sure similar things apply in other jurisdictions too.)
Thanks, Alex. Ticketed here:

Will take some time ofc but good to plant the seed now. :)
OSE actually has it on its roadmap: https://github.com/osendowment/foundation/blob/main/roadmap....
Most likely we won't create our own subsidiaries, but will partner with local nonprofits (suggestions are welcome), which could make donations tax-deductible for UK/EU residents.
As for grants, we are totally fine with supporting European open source maintainers now. OSE has a global scope, limited only by the available payment infra and US regulations.
> will partner with local nonprofits
mmh. be very careful when choosing those. Esp. in former socialistic countries, and esp. in some of them (hint), where $$$ scheming has become bread-and-butter of the.. kind-of-former-but-new aparatchiks.. it's like an official mafia. Electrically speaking, they manage to find ways to ground and leech on any potential.. $100 or $100M alike.
otherwise - great initiative. The Commons (as of ivan ilich) need support and care in order to be .. there when needed.
Sure - we donate our own money to this endowment fund and carefully choose partners who have a solid reputation and can deliver maximum efficiency. I don't think we will have any of them in former socialist countries,except for those based in Berlin :)
Just for the love of all things, do not let this become like Wikipedia or Mozilla. The moment you start paying for irrelevant things, you lose donors current and in the future. Nothing more frustrating than those two orgs in terms of where they spend their donor funds.
I am one of https://wikimediaendowment.org/benefactors (donated years ago), and now I am totally unhappy with what is happening with Wikipedia. It has been an important lesson learned.
To keep a nonprofit efficient and impactful, it is crucial for its governance to have skin in the game; otherwise, there will be no long-term alignment of interests. More details on why and how we implement this at the Open Source Endowment: https://kvinogradov.com/osendowment
How is this different than something like https://opencollective.com (which, for example, Actual Budget uses: https://opencollective.com/actual )
Open Collective (OC) is great! It's primarily a payments platform.
Open Source Collective (OSC, which is related to OC in convoluted ways I don't fully understand) is a fiscal sponsor of OSS projects, and is also great. :^)
Open Source Endowment (OSE), on the other hand, is a pile of money that earns interest that then gets distributed to OSS projects. So conceptually some projects either fiscally hosted by OSC or using OC as their payments platform could receive funds from OSE.
Does that help?
Edit to disclaim: I'm on the OSE board.
Open Collective (really Open Finance Consortium Inc.) is a US 501(c)(6) nonprofit that runs a payments and accounting platform, providing fund acceptance and budget services to a ton of different community collectives and funding groups, making it easier to connect funders with groups that are often not incorporated.
Open Source Collective is a separate 501(c)(6) organization that actively supports funders wanting to support FOSS projects or communities specifically. They share some board members, and they simply use Open Collective to do all the finance work, while also offering some level of advice and other IP holding services: https://docs.oscollective.org/welcome-and-introduction-to-os...
Open Source Endowment is different, in that it's soliciting 501(c)(3) donations, which the OSE board and membership will use for the endowment to choose FOSS projects/communities to provide grants for.
This topic should be a FAQ page on the OSE site, especially for funders who just want to donate "to some good FOSS" without knowing where to find it. When you donate to OSC, you pick specific collectives to give to (and it's not tax deductible). When you donate to OSE, you're giving to the endowment, that the OSE Members setup policies for how/where/when to provide grants to projects/communities (and it could be tax deductible).
Good on ya.
I work on a nonprofit platform that isn't "critical infrastructure," compared to a lot of stuff, so I'd likely not seek funding, in order to avoid stealing oxygen from the lone maintainer in Nebraska.
The FAQ, under "How can OSE evolve in the long term, especially in an AI-powered world?" appears to state a very pro-AI view.
I think this is hopelessly naive. The LLMs crapping out code are shamelessly ripping off open source code, sans copyright notice. It makes no sense for a foundation supporting open source to also support this massive copyright massacre.
Also, I think you're going to get flooded with requests to give money to vibe-coded crap, because if you have no skills or shame but want to make a little money off your AI-generated crap, why not try and extract money from this initiative? The curl guy showed this is very real.
The curl guy is one of OSE founding donors, together with the terraform guy who recently released an open source trust management system to help with AI-generated crap: https://github.com/mitchellh/vouch
I think that AI eventually will solve technical maintenance problems, but not human-related ones: limited attention, trust, motivation issues. And we are going to support mostly "old" projects everybody relies on, not some new AI-gen stuff.
Potential issues from new tech aside, an open-source endowment is a pro-social idea, that absolutely deserves its day.
Now, setting aside ethical issues for a moment, open-sourced knowledge, writing, history, data, Q&A, and tech is essentially a prerequisite for a data-driven technology like LLMs, and if those turn out to be a net win for humanity, then we can directly trace the routes to initiatives like this one that can curate humanity's best contributions.
> flooded with requests to give money to vibe-coded crap
And our plan is to willy-nilly give money to everyone who asks for it with no oversight or attention to other factors or human involvement. Game over. You win.
Tax dollars to find software
lets try something new
Putting capitalists in the middle doesn't seem new, more like another place they can extract a slice of the pie.
Let's back up: The way an endowment works is that donors donate money, which goes into a more-or-less permanent investment fund. The interest from the investment fund is then used to a) fund mission-aligned programs (in our case, OSS), b) stay ahead of inflation, and c) pay operating costs.
Where are you seeing capitalists "extract a slice of the pie" here?
The README on github
"pay operating costs" is one place non-profits often find fraud. Getting the money into the market between donors and builders, now you have to pay professional investors. You don't get to 7-8% returns without equities, what happens if the market tanks?
Why not build something super minimal that requires less management and operating costs? That doesn't have the market risk at the center of it all? That doesn't have more points for fraud and abuse?
> "pay operating costs" is one place non-profits often find fraud.
If you find it here please let us know.
Can you explain the 2-3% gap between expected returns and outlays? Seems like a lot more than what is needed for accounting (based on the other main person here posting)
The explanation is simple — nobody can predict exact annual returns, and they tend to fluctuate. We aim to spend at least 5% per year on OSS grants and need to decide if we can spend more on them or should reinvest based on specific annual results. And target earnings should overcome inflation.
So.... you just created a 501(c)(3) tax-exempt organization to offer grants for product development.
Yeah, this will end well.
Here are a couple salient portions of our IRS application to put your mind at ease. :^)
> In limited circumstances, the Foundation may make grants to organizations that are not described in IRC Section 501(c)(3), or to individual OSS developers, maintainers, researchers, and educators. These grants will support persons and organizations engaged in developing, maintaining, securing, documenting, or conducting research on free and open source software critical to public digital infrastructure.
> Any such grants will be made exclusively for charitable or educational purposes, with the Foundation retaining complete discretion and control over the use of funds consistent with Revenue Ruling 68-489.
[...]
> In addition to project-based grants, the Foundation will make recognition awards to individuals who have made extraordinary contributions to OSS serving as critical public digital infrastructure. These awards are analogous in structure and purpose to MacArthur Fellowships, the National Medal of Science, Pulitzer Prizes, and similar recognition programs administered by 501(c)(3) organizations.
Boldly asserting that all grants will be made exclusively for charitable or educational purposes does nothing to change the character of the grant. If you're giving money to someone for commercial product development then you're giving money to someone for commercial product development ... and if that constitutes the majority of what you do then you've got a major problem.
OSE won't give money for commercial product development - it is dedicated to supporting existing highly-used _nonprofit_ and independent OSS. Some specific examples are at https://endowment.dev/faq/#grants
clear and plain language on the website will do wonders compared to legal like comments with emoticons on HN
> founders of HashiCorp, Elastic, ClickHouse, Supabase, Vue.js, Pydantic, Nginx, Gatsby, n8n, and curl
By the sound of it, we can probably expect most of the stakeholders to be less interested in critical infrastructure or anything that solves real problems for actual human beings and more interested in the kind of frivolous devops make-work that creates more problems than it solves.
Kinda up to you. Recruit your friends to join if you want a say. :^)
> Individuals contributing at least $1,000/year to the endowment fund qualify as OSE Members. Members advise the OSE board on strategic matters, such as the grant-making model, and appoint community-nominated board directors. These rights are legally defined in our membership policy.
https://github.com/osendowment/foundation?tab=readme-ov-file...
It is a community-driven initiative - we encourage developers to join as donors and help to shape it. Also, our model from the very start is about deep layers of infrastructure: https://endowment.dev/endowment/#model.
Finally, I would not say that, let's say, founders of Nginx and curl are not interested in critical infra or don't understand it :)
