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.
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.
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).
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.
> 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.

The global average salary of a software engineer is $5,906/month, and the OSE membership is $83/month ($1,000/year), so it would require donating ~1.4% of gross income. This aligns fully with the 1-2% of income that an average U.S. individual donates every year, and we are targeting more senior engineers, not the average ones.
So it is affordable for our target audience, but requires some personal commitment. To be efficient in the long term, an endowment must be managed by people who have skin in the game.
It would also be irresponsible to have people who can't or don't want to personally donate $1,000 to our cause, or people outside of the tech industry, managing a multi-million-dollar community fund focused on solving a pretty niche industry problem. Otherwise, the endowment ends up being as efficient as a typical government!
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 :)

Congratulations, you managed to pick out the two projects in the set that makes it merely "mostly" (instead of "entirely") frivolous.
It requires choosing projects, and most people don't have time for this.
But the main problem is that such funding is simply not sustainable: corporate annual budgets for OSS are volatile, and individual donations are extremely volatile. It is not great for the critical infrastructure we all rely on.
The Open Source Endowment enables truly sustainable funding and also decreases the entry barrier for new OSS donors because it does not require choosing a specific project. A la buying the S&P 500 ETF instead of stock picking.
> Congratulations, you managed to pick out the two projects in the set that make it merely "mostly" (instead of "entirely") frivolous.
Out of curiosity, which founding donors specifically would qualify under your criteria for a "serious" project? If the founders of HashiCorp, Elastic, ClickHouse, Supabase, Nginx, and curl seem like a mostly frivolous band to you...
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.
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.
LLMs represent a very important opportunity to force-multiply limited resources.
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.
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.
Copyright is a fundamentally unethical concept and must die. Open source foundations should rightfully support the death of copyright, whether by LLMs or by other means.
Where are you seeing capitalists "extract a slice of the pie" here?
"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?
If you find it here please let us know.
> 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?
could still be usefully addressed.
Now OSE has no paid employees - the team is 100% volunteers. Its Board Directors and the Executive Director are required to personally donate $1000+/year. Operating costs are close to zero.
As organization evolves there might be higher operating costs, but our commitment to keep them as low as possible.
But all other areas should be as low-risk as possible — like accounting, legal, and investment management of a community endowment fund. We are exploring a few ideas on how to grow the fund faster than the market without increasing its risk profile, but they are complementary to a very conservative core strategy.
Besides OSE, I am a full-time VC — that's the area where investors are bold and invest in off-norm opportunities, but it lies on the totally opposite side of the investment risk spectrum. And directly mixing them does not seem like a good idea.
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.)
https://github.com/osendowment/foundation/issues/26
Will take some time ofc but good to plant the seed now. :)
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.
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.
Yeah, this will end well.
> 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.
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
I have my opinion on why this is happening and my explanation is that in Mozilla they lost their memory because they act as a company and not as a foundation (they have both the identities). With the layoffs they removed a lot of people working there for years that knows a lot, they lost the historic memory and I remember a lot of discussion with employees that had no idea that there was a community or that they have no idea what is a GPL license. I mean in 2018 I remember reviewing this as part of the Mozilla Reps council, https://github.com/OpenTechStrategies/open-source-archetypes that was created to help the employee to understand OSS but I think that after the managers that created moved away it was just left as it is.
Sorry for the flame but I think that when a foundation act like a corporation there are issues.
These are people who have net worth values in the 10's to 100's of millions of dollars and they could only give ~10k to open source software?
My goodness we're cooked. The oligarchs are so unbelievably cheap.
May I ask what it’s the right share of net worth one should donate to OSS? And what’s this share in your personal case?
I am not a high net worth individual. With a 20 year career as an IC in the tech industry though, I'm quite comfortably middle class. But even I have donated $10k to charity in a single year many times. Many tech companies offer charity gift-matching programs. I take full advantage of those by having a donor advised fund so I can capture the full gift match amount every year and then disburse those funds as desired. When I was briefly at Microsoft, they had an oddly generous gift match of up to $15k per year. I literally put up $15k of my own money each year to capture that $30k/year into a charity account for several years.
That's why I feel like I can comment critically on this. I'm a regular dude who grew up dirt-poor and ended up modestly successful in life and even I can manage to donate amounts of 10's of thousands annually.
Compared to the much more successful executive, CEO, founder class who you mentioned were among your donors. To the kind who own houses in the Los Altos hills worth 10 million plus, those numbers seem kind of paltry.
I'm not trying to take away from the success of your organization and its mission. I congratulate you on your fundraising efforts and I know you can't afford to be critical of your donors lest those donors sour on you. But truly, it does strike me how some of the wealthiest among us, who have benefited the most from these common goods, can give so little.
We are not building yet another HNWI-focused nonprofit, but a grassroots community endowment. It targets a donor like you – a regular tech industry worker who can support things they truly care about with a $1-100k donation. I think many developers love open source, don't they?
We intentionally targeted launching the endowment with a $0.5-1m initial size and many donors because:
1) It is not attractive for regular donors to support a project that is heavily funded by HNWIs. Let's say if I were able to donate to the Gates Foundation, it would be like peeing in the ocean and wouldn't matter. However, I am eager to support projects with peers among donors because it makes a difference. And that's the way to make OSE scalable and outlive all its founders.
2) It is important to maintain high decentralization of funding, which enables good community governance and accountability. Having a few outsized donors at the start kills it. Our donor Herfindahl–Hirschman index is ~1800 now.
3) As a VC (maybe a bit old school), I think that it is responsible to limit funding size at very early stages and grow it later together with achieved milestones and decreasing risks. It helps to build more efficient organizations.
Just take a look at https://endowment.dev/community - we obviously targeted notable founders at the start, but now it is a healthy mix with many everyday developers. You're welcome to join them.
Of course, OSE will look for large donations. But the goal is to raise them in balance with growing a community of smaller donors, maintaining decentralization and scalability.
The biggest issue that I see is that even for things that are in some respects "finished", grants on the order of $5k do not change the maintainance picture very much at all. If there's a sudden crisis with critical infrastructure, people will step. But that's precisely what we want to move away from, and to do that the funding needs to be living-wage level, not single-issue grants.
It is awesome when those grants happen, and specific new features or compatibility are worked on. But the sustainability question is really not about that kind of work, for the most part. Somebody needs to actually be the guy in Nebraska and they need to consider that their role. Possibly it is just one role among a few, but it needs to be bigger than a one-and-done $5k-sized role.
The question is really how to redirect the streams of revenue that currently flow toward capital so that the people who work on OSS can do this as a living, not a part time calling. I don't see grants as a significant part of that.
As it grows bigger, the grant size will also grow. One can help with this by donating and bringing in new donors!
On a global scale, likely less than 10% of the world's population has ever been able to save $5,000 at any point in their life, with the vast majority concentrated in high-income countries. In low- and middle-income countries, this is a rare achievement limited to a small, affluent minority.
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
