The organization over time
Each line starts at 100 in 2018, so what you read is the shape rather than the size: 150 means half as much again as 2018, 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.
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.
57% of Sonoma Speaker Series’s revenue is contributions — about as donation-reliant as the typical peer (58% for the typical peer).

the vertical line marks half of all grant income — 2 funders to its left
34% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund Sonoma Speaker Series.
Largest funder’s share by year: 2019 100% · 2020 100% · 2021 100% · 2022 100% · 2023 54% — diversifying over time.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $77k arriving through sponsors registered in 4 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.
