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 2020 to 2021, from $109M to $134M (+22%).
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.
41% of SIBLEY MEMORIAL HOSPITAL FOUNDATION’s revenue is contributions — more reliant on donations than three-quarters of its peers (7% for the typical peer).

Who funds it, year by year
2017 → 2023: the base broadened from 18 funders to 59 funders, grant income rose $432k → $6.2M.
18 of 134 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 18% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
Left out of every figure on this page: $3.0M from 10 payers (the payer shares this organization's board, largest The Washington Home Inc). These are real filings, and they are not money SIBLEY MEMORIAL HOSPITAL FOUNDATION raised.
