Disclosed funding in this “Series Unknown” environmental-services slice is uneven: the largest disclosed round is cimico’s $8M on 2023-07-18, and it sits well above the next-largest disclosed amounts, including Climate Vault ($7M on 2023-05-04) and EnviroCentre ($2M on 2024-10-22). At the bottom end, disclosed amounts cluster into sub-$1M figures such as Brightwater Tools ($10K on 2024-06-18) and Agricarbon ($50K on 2025-03-04), while three entries have “undisclosed” amounts (Plant-for-the-Planet on 2024-12-03, Foothill Conservancy on 2024-04-22, and Gigablue on 2023-10-06).
Timing also shows clustering near the present: of the 23 rows shown, the most recent round is Open Space Institute on 2025-06-12, and 4 rounds (from 2024-09-18 through 2025-06-12) fall within roughly a 9-month window. Geographically, the set is internationally distributed, but the United States is prominent across multiple locations (e.g., EnviroCentre in Kentucky, Climate Vault in Illinois, and Tree Trust in Minnesota), with single entries for the United Kingdom, Germany, Israel, Poland, Peru, Spain, and several others.

Frequently asked
What’s the largest disclosed round here, and how much do the rest of the disclosed amounts lag it?
cimico’s $8M (2023-07-18) is the top disclosed amount in the 23-row view, followed by Climate Vault at $7M (2023-05-04) and then several smaller rounds like EnviroCentre’s $2M (2024-10-22). Below that, many disclosed entries are far smaller, including Brightwater Tools at $10K (2024-06-18) and Agricarbon at $50K (2025-03-04).
How many rounds are undisclosed, and which specific companies are they?
Three of the 23 rows list “undisclosed” amounts: Plant-for-the-Planet (2024-12-03), Foothill Conservancy (2024-04-22), and Gigablue (2023-10-06). These are excluded from “largest/smallest disclosed” comparisons, which are dominated by the $8M–$100K range.
Which entries fall into the most recent 90 days of the rows shown?
Using the page’s latest date (2025-06-12, Open Space Institute) as the anchor, entries within the prior ~90 days include Open Space Institute ($1M on 2025-06-12) and Agricarbon ($50K on 2025-03-04). No other dated rows appear between 2025-03-04 and 2025-06-12.
Is there a tight date window where multiple rounds cluster?
Yes. Four rounds land within about 9 months from 2024-09-18 through 2025-06-12: Zulu Ecosystems ($760K, 2024-09-18), EnviroCentre ($2M, 2024-10-22), Open Space Institute ($1M, 2025-06-12), and Agricarbon ($50K, 2025-03-04).
Are any geographies repeatedly represented, or is it mostly singletons across countries?
It’s mostly international with single-country entries by company, but the United States appears repeatedly across different cities/states (e.g., EnviroCentre in Kentucky on 2024-10-22, Climate Vault in Chicago, IL on 2023-05-04, and Tree Trust in Saint Paul, MN on 2023-05-08). Non-US entries include the UK (Agricarbon is Dundee; Seafields Solutions is Stockport) and Germany (Plant-for-the-Planet in Bayern).
What are the biggest low-end outliers among disclosed amounts?
Among disclosed rounds, Brightwater Tools at $10K (2024-06-18) is the smallest disclosed amount in this list, while several other low figures sit in the tens of thousands such as Pando Populus at $20K (2023-12-01) and Ecobean at $90K (2022-12-01). These are separated from the top-tier disclosed amounts like cimico’s $8M (2023-07-18) and Climate Vault’s $7M (2023-05-04).
