As stated on its FY2025 Form 990.
Programs
On its FY2024 return the organization reported a significant change in how it conducts a program.
In december 2024 we experienced a fire that impacted about 50% of our building. With that in mind, we had to adjust the way we offered a variety of our programs. City of sunnyvale contract: the fire at our facility caused significant damage, and we no longer had the appropriate space available to house the number and type of animals required to fulfill the sunnyvale contract. Program locations: without the original space, we moved locations of a variety of our programs to keep them operating. These include: onsite vaccine clinics: moved from the medical center to onsite vaccine clinic trailers. Spay/neuter surgeries: moved from the medical center to the hssv wellness waggin and a recovery trailer. End of life services: moved to an onsite trailer. Dog adoptions floor: created a new dog adoptions floor within our "classrooms." dog training: our dog training room was needed for additional animal housing and operations, therefore training was relocated to our onsite dog parks.
Its own explanation, from Schedule O of that return (Part III, line 3).
Programs for saving lives: adoptions and animal care:- adoptions facilitates adoptions by matching prospective pet owners with the right pet for their family, supplying information on pet care to ensure a successful adoption placement, and providing post adoption support to adopters.

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 $55M to $65M (+18%).
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.
Government-grant reliance: 2021 7% · 2022 8%. Grants only. Government contracts and fees sit inside program revenue.
87% of HUMANE SOCIETY SILICON VALLEY’s revenue is contributions — more donation-reliant than the typical peer (67% for the typical peer).

30 of 177 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 64% 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 HUMANE SOCIETY SILICON VALLEY’s funders (the co-funder graph). Top 30 of 177 funders by total. Association, not causation.

How concentrated its funding is
HUMANE SOCIETY SILICON VALLEY has a broad base — no single funder exceeds 16% of grant income, and it takes 4 funders to reach half.
the vertical line marks half of all grant income — 4 funders to its left
67% 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 HUMANE SOCIETY SILICON VALLEY.
Largest funder’s share by year: 2017 27% · 2018 37% · 2019 43% · 2020 35% · 2021 24% · 2022 40% · 2023 55% — growing more concentrated.
“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.
How long its funders stay
42% of HUMANE SOCIETY SILICON VALLEY's funders are still giving 3 years after their first grant; 64% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
64% of HUMANE SOCIETY SILICON VALLEY's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $12M that is directly attributable, 88% of it comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $21M arriving through sponsors registered in 19 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.
