What Yc Org does
Mission
YC ORG is a non-profit corporation organized and operated exclusively for charitable purposes. The specific purpose of this organization is to support other charitable organizations conducting charitable activities. YC ORG furthers its purpose by making grants to other 501(c)(3) initiatives and activities that are trying to solve the worlds problems. The overall goal is to further scientific research that will ultimately be made freely available to the public.
As stated on its FY2019 Form 990-EZ.
Program
YC ORG continued facilitating the success of a number of charitable projects and organizations in 2019. Fewer grants were made in 2019 so YC ORG could focus on reviewing the progress of the projects it supported in prior years, including Watsi, Y Combinator Research (Basic Income study, Research Fellows, Dynamicland), OpenAI (Artificial Intelligence Research), and Watsi (Infrastructure for Universal Healthcare Access). All supported projects/organizations provide YC ORG with periodic updates and accounting of the use of their grants.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2018 to 2019, from $37k to $8k (−79%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
100% of YC ORG’s revenue is contributions — more reliant on donations than three-quarters of its peers (95% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 3 reported years ran a deficit.

Who funds it, year by year
2017 → 2018: the base held at 1 funder, grant income fell $10M → $253k.
3 of 4 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 6% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of YC ORG’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
YC ORG leans on a few funders — its largest provides 94% of grant income and the top three 99%; half comes from just 1 funder.

Largest funder’s share by year: 2017 100% · 2018 100% — broadly stable.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Where its funders are
YC ORG draws 100% of its grant income from funders outside California, across 1 state in all.
Funder states come from each funder’s own filing. $593k arriving through sponsors registered in 3 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Against its field
YC ORG runs a healthier operating margin than three-quarters of the 5,036 philanthropy nonprofits its size.
