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.
Balance sheet
Total assets at each year end, in dollars. The largest one-year move in total assets was 2023 to 2024, from $130k to $83k (−36%).
How it's funded, over time

85% of 350 Colorado Action’s revenue is contributions — about as donation-reliant as the typical peer (92% 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.
