What Ultimate Block Party Inc does

Mission

Playful learning landscapes transforms the places where children and families gather every day into thoughtfully designed hubs for meaningful play and connection.

As stated on its FY2024 Form 990.

Programs

  1. Playful learning landscapes partners with communities in the u.s. And beyond to turn everyday places into vibrant hubs of learning and connection for kids and families. Using a science-based approach called playful learning, we design and build interactive installations that create a new kind of public square where young children, guided by adults, can develop the cognitive and social skills they need to thrive.

Each line starts at 100 in 2019, so what you read is the shape rather than the size: 150 means half as much again as 2019, 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.

Who funds it, year by year

2020 → 2023: the base broadened from 3 funders to 4 funders, grant income rose $239k → $959k.

2 of 7 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 3% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

Funder states come from each funder’s own filing. $88k 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.
