As stated on its FY2025 Form 990.
Programs
During 2025, reverb's major program accomplishment areas were connected to three marquis programs and artists: billie eilish tour, dead & company at the sphere and the tame impala tour.reverb had the honor of again joining forces with billie eilish, who we began working with in 2020. Billie is an incredible activist and her passion for the environment coalesced into a fantastic reverb action program both in the front-of-house and backstage on her "hit me hard and soft" tour. The statistics and actions have been remarkable. On billie's tour over 215,000+ total fan actions we taken on-site; over $13.3 million was raised to support nonprofit organizations, environmental justice and climate projects through billie's "changemaker" ticket fund as a way to collaborate with fans to raise money for nonprofits addressing the climate crisis, food insecurity and climate justice issues which deeply align with reverb's core values and mission. Reverb was honored to have been entrusted by billie and her team to steward the distribution of those funds as grants for the north american leg of her tour; 1,746 volunteers donated over 3,800 hours to help fellow fans take action for people and the…

Reverb was the production arm behind "participation row" along with our voter registration partners at headcount. During this residency at the sphere in las vegas, there were over 40,000 onsite and online fan actions taken; $1.5 million raised for dead & co. Charity organizations; and 174 volunteers gave over 1,290+ hours to help raise awareness about our work. It was an incredible experience to be at this innovative, new venue bringing to life programming for these artists who have led the charge within the music industry as cultural change-makers since the 1960's.

Although the tour is rolling on into 2026 the successes were many. Reverb distributed re-usable water bottles and offered free filtered water through our nalgene #rocknrefill partnership and thus avoided over 3,715 disposable plastic water bottles being used. We hosted 139 volunteers who gave 556 hours of their time to support the nonprofit action village partners. 4,074 fan actions were taken via our "climate quiz and our "fit check" (regarding fast-fashion and its impact on the planet). We are grateful to continue our good work for the planet together into 2026.

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 2023 to 2024, from $5.3M to $8.4M (+58%).
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: 2017 3% · 2018 3% · 2019 2% · 2020 10% · 2021 2% · 2023 4%. Grants only. Government contracts and fees sit inside program revenue.
84% of REVERB INC’s revenue is contributions — about as donation-reliant as the typical peer (88% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 4 of the last 9 reported years ran a deficit.

The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.
Who funds it, year by year
2017 → 2023: the base broadened from 1 funder to 6 funders, grant income rose $57k → $209k.
9 of 18 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 76% 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 REVERB INC’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
REVERB INC leans on a few funders — its largest provides 52% of grant income and the top three 69%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
93% 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 REVERB INC.
Largest funder’s share by year: 2017 100% · 2018 57% · 2019 50% · 2020 25% · 2021 89% · 2022 79% · 2023 59% — diversifying over time.
“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
43% of REVERB INC's funders are still giving 3 years after their first grant; 44% 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
76% of REVERB INC'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 $551k that is directly attributable, 100% of it comes from funders outside Maine, across 6 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.8M arriving through sponsors registered in 7 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.
