On February 26, 2026, former GitHub CEO Thomas Dohmke, HashiCorp founder Mitchell Hashimoto, and the creators of Vue.js, cURL, and NGINX launched the Open Source Endowment with $752,000 from 102 donors. It’s the world’s first endowment fund for open source software, and it works exactly like Harvard’s $53 billion endowment: invest all contributions into a low-risk portfolio, spend only the investment income (approximately 5% annually), and preserve the principal indefinitely. The timing is deliberate. Kubernetes just retired Ingress NGINX after years on 1-2 weekend maintainers, and the xz Utils backdoor succeeded because one unpaid developer was overwhelmed. Unlike GitHub Sponsors or corporate donations that stop when companies pivot, OSE’s investment income continues regardless of market crashes, donor fatigue, or shifting corporate priorities.
Critical Infrastructure Is Collapsing Right Now
Kubernetes announced Ingress NGINX’s retirement in November 2025 with final security patches ending March 2026—weeks from now. The reason? Years of relying on 1-2 part-time maintainers who burned out. One of the most widely deployed Kubernetes components will receive zero security patches because nobody wanted to maintain critical infrastructure for free.
This isn’t an isolated incident. The xz Utils backdoor in 2024 succeeded because the sole unpaid maintainer was overwhelmed and vulnerable to social engineering. Heartbleed in 2014 exposed OpenSSL protecting billions in commerce while receiving only $2,000 per year in donations—a $100,000 security audit would have caught the bug. External Secrets Operator froze all updates in early 2026 when four maintainers burned out, leaving one active contributor for enterprise deployments depending on the project.
The OSE launched two months after Ingress NGINX’s retirement announcement and two years after the xz Utils backdoor. This isn’t solving a future threat. It’s a direct response to infrastructure collapse happening right now, and 60% of open source maintainers working unpaid with 44% citing burnout as their reason for quitting.
How University Endowments Work: Perpetual Funding vs. Band-Aids
The OSE invests all $752,000 into a diversified, low-risk portfolio exactly like Harvard’s endowment. Universities earn approximately 7% annual returns, spend 5% on operations, and reinvest 2% to beat inflation. Harvard’s endowment grew from millions to $53.2 billion over centuries because the principal never gets touched. OSE founder Konstantin Vinogradov explained: “The global open-source community shares many parallels with how the best universities work, and we are thrilled to adopt their private endowment model.”
At 5% annual spending, the current $752,000 generates $37,600 per year starting Q2 2026 when the first grant round opens. Vinogradov targets $100 million in seven years, which would produce $5 million annually in perpetual grants—enough to fund 10 critical projects at $500,000 per year each, or approximately three full-time maintainers per project. The principal grows while the income continues forever.
This is structurally different from GitHub Sponsors, Open Collective, and corporate donations. GitHub Sponsors creates dependency without stability—76% of tiers earn less than $100 per month, and donations stop when sponsors lose interest. Facebook cut funding for React Native for Windows when priorities shifted. Google regularly sunsets projects. Corporate sponsorships disappear during layoffs or strategy changes. OSE’s investment income continues regardless of donor attention, economic conditions, or corporate pivots. It’s the difference between a subscription that cancels (fragile) and a trust fund (perpetual).

Tech Leaders Who Made Billions on OSS Are Now Funding It
The OSE’s 102 donors include Thomas Dohmke (former GitHub CEO who raised a record $60 million seed round for his AI governance startup Entire in February 2026), Mitchell Hashimoto (HashiCorp founder whose company sold to IBM for $6.4 billion in February 2025), Paul Copplestone (Supabase CEO), and the creators of NGINX, Vue.js, and cURL. These are tech leaders who built billion-dollar companies on free open source labor, now funding the infrastructure that enabled their wealth.
The backer quality matters. Dohmke led GitHub, which was built on Git (open source). Hashimoto built HashiCorp’s entire product line—Terraform, Vault, Consul—on open source tooling and sold to IBM for $6.4 billion. Among the 102 donors, 62 gave $1,000 or more to earn “member” status, with the remaining 40 averaging $17,250 per donation. This isn’t a crowdfunding campaign from unknowns. These backers have direct experience with open source economics and are validating the urgency with meaningful financial commitments.
The Math: $37K Now, $5M Annually in Seven Years
At 5% annual spending, the current $752,000 endowment generates $37,600 per year starting Q2 2026 when the first grant round opens. One senior engineer costs approximately $150,000 annually. Three full-time maintainers plus administrative overhead equals roughly $500,000 per year per project. The current endowment funds one-quarter of one maintainer—meaningful but insufficient for most critical projects.
Vinogradov’s target is $100 million in seven years. At 5% spending, that generates $5 million annually in perpetual grants. Ten critical projects could each receive $500,000 per year (three full-time maintainers) indefinitely. Reaching $100 million requires approximately 45% annual growth in donations—aggressive but achievable if more tech executives commit. One $10 million donation from a single company would provide 13+ years of current grant funding immediately.
Skeptics question the timeline. Hacker News reactions ranged from “structural solution instead of Band-Aids” (optimists) to “$750K is nothing compared to billions in unpaid labor” (realists) to “Most OSS projects will die before seven years” (pessimists). The counter-argument: Even $37,600 per year helps when OpenSSL survived Heartbleed on $2,000 annually. If 10 tech executives donate $10 million each, OSE hits $100 million immediately without waiting seven years. Dohmke and Hashimoto set the precedent for high-value donors.
What Happens Next
The first grant round opens Q2 2026 with nominations accepted now through the OSE website. Projects will be selected based on criticality metrics—dependency graphs showing how many other projects rely on the infrastructure, security impact of potential failures, and ecosystem importance. The selection process aims to identify truly critical but underfunded infrastructure rather than high-profile projects that already have corporate backing.
The seven-year timeline to $100 million is ambitious. Success depends on sustaining donor momentum and demonstrating tangible impact from early grants. Q2 2026 grants will serve as proof-of-concept—if OSE can fund maintainers for critical projects and prevent another Ingress NGINX collapse, the model proves itself. Failure to show results quickly risks donor fatigue.
This isn’t claiming to solve the entire open source funding crisis alone. GitHub Sponsors, Open Collective, the Sovereign Tech Fund in Germany ($26.8 million in government funding), and corporate sponsorships all play roles. OSE provides one structural solution: perpetual funding from investment income instead of dependency on annual renewals. It’s Harvard’s 400-year-old model finally applied to open source infrastructure.
Key Takeaways
- The Open Source Endowment launched February 26, 2026 with $752,000 from 102 donors including former GitHub CEO Thomas Dohmke and HashiCorp founder Mitchell Hashimoto, adopting university endowment models (invest principal, spend only 5% income annually, preserve capital indefinitely)
- Critical infrastructure is collapsing now, not in the future—Kubernetes Ingress NGINX retires March 2026 after 1-2 weekend maintainers burned out, xz Utils backdoor succeeded due to one overwhelmed developer, and 60% of maintainers work unpaid
- University endowment model provides perpetual funding that survives corporate pivots and donor fatigue, unlike GitHub Sponsors (76% earn under $100/month) or corporate sponsorships that disappear when companies change priorities
- Current $752,000 generates $37,600/year in grants starting Q2 2026; target of $100 million in seven years would produce $5 million annually to sustain 10 critical projects with three full-time maintainers each
- First grant round Q2 2026 will serve as proof-of-concept—success depends on demonstrating tangible impact and sustaining donor momentum to reach the $100 million target
