What JULIAN GAU Horizon Ensemble Inc does
Mission
The mission of the Horizon Ensemble is to enrich the artistic and cultural lives of our communities of musicians and audiences through our orchestral concerts. We serve the community of the Boston area by providing accessible musical performances at no cost in a historical space. We also support the community of musicians in Boston by acting as a high-level ensemble playing unique repertoire with a relatively short rehearsal cycle. Finally, we further the artistic development of the community of young composers by providing them with performances of large-ensemble pieces, a much-desired opportunity.
As stated on its FY2025 Form 990-EZ.

The 8 programs described on its FY2025 Form 990-EZ. Program spending in total: $35,803.
The organization over time
Each line starts at 100 in 2022, so what you read is the shape rather than the size: 150 means half as much again as 2022, 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 2024 to 2025, from $7k to $1k (−84%).
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.
86% of JULIAN GAU Horizon Ensemble Inc’s revenue is contributions — more donation-reliant than the typical peer (78% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 4 reported years ran a deficit.
Who funds it, year by year
Grant support over time, funder by funder — shade shows the grant size each year.
1 of 1 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 100% 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 JULIAN GAU Horizon Ensemble 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.
Where its funders are
100% of JULIAN GAU Horizon Ensemble 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. Too little is directly attributable to place on a map.
Funder states come from each funder’s own filing. $10k arriving through sponsors registered in 1 state 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.
