Across the 14 most recent environmental services rounds shown, the largest disclosed amount is BurnBot’s $20M (2024-04-02). That $20M round sits far above the next-largest disclosed amounts visible here: EnviroCentre’s $2M (2024-10-22) and Tree Trust’s $2M (2023-05-08), while several other disclosed rounds are in the tens of thousands ($60K on 2023-12-06 for Washington Water Trust; $100K on 2022-11-18 for Orono Spectral Solutions) or below ($10K on 2024-06-18 for Brightwater Tools).
The list also clusters temporally: four disclosed rounds fall between 2024-04-02 and 2024-10-22, and multiple entries land in late 2023 (Wild Me $250K on 2023-12-20; Washington Water Trust $60K on 2023-12-06; Pando Populus $20K on 2023-12-01). Geographically, the United States is represented across many cities, but Illinois appears twice (Illinois Green Alliance on 2023-08-10, and Climate Vault on 2023-05-04). Stage and disclosure are also uneven: 10 of 14 entries are labeled “Series Unknown,” and three entries use “undisclosed” instead of a dollar amount.

Frequently asked
What’s the biggest disclosed round in this set, and how isolated is it by amount?
BurnBot’s $20M (2024-04-02) is the only disclosed round at that level; the next-largest disclosed amounts in the table are $2M for EnviroCentre (2024-10-22) and Tree Trust (2023-05-08), with other disclosed rounds clustered far lower (for example $250K on 2023-12-20 for Wild Me and $60K on 2023-12-06 for Washington Water Trust).
Do the most recent rounds cluster into a specific date window?
Yes. Several entries concentrate in late 2023: Wild Me ($250K) on 2023-12-20, Washington Water Trust ($60K) on 2023-12-06, and Pando Populus ($20K) on 2023-12-01. The list’s most recent row is Open Space Institute on 2025-06-12 ($1M), while the oldest shown is Orono Spectral Solutions on 2022-11-18 ($100K), spanning about 2.5 years.
Which disclosure/stage labels dominate the dataset?
“Series Unknown” appears in 10 of 14 entries (for example Open Space Institute $1M on 2025-06-12; EnviroCentre $2M on 2024-10-22; Climate Vault $7M on 2023-05-04). “Undisclosed” appears 3 times (Foothill Conservancy on 2024-04-22; Illinois Green Alliance on 2023-08-10; Mold Medics on 2023-05-11; Ally Waste Services on 2023-02-08 is also “undisclosed”), limiting amount-based comparisons.
Are any states or cities repeated more than once?
Illinois shows up twice: Illinois Green Alliance in Chicago on 2023-08-10 (undisclosed) and Climate Vault in Chicago on 2023-05-04 ($7M). California also appears multiple times via BurnBot in San Francisco ($20M, 2024-04-02), Foothill Conservancy in Jackson (undisclosed, 2024-04-22), and Pando Populus in Los Angeles ($20K, 2023-12-01).
Are there outliers beyond the largest amount that suggest different risk/traction signals?
The disclosed amounts include both very small rounds and one very large one: Brightwater Tools raised $10K (2024-06-18) and Pando Populus raised $20K (2023-12-01), while BurnBot raised $20M (2024-04-02). Separately, four entries are labeled “undisclosed,” including Foothill Conservancy (2024-04-22) and Mold Medics (2023-05-11), which can obscure whether they represent high-velocity scaling or smaller pilots compared with disclosed peers like Tree Trust ($2M, 2023-05-08).
