Across these 47 Natural Resources rounds, one disclosed deal stands well above the field: Central States Water Resources raised $325M on 2024-12-02. The next-largest disclosed amounts are $100M (Aquaria, 2024-11-20) and $44M (Hycroft Mining, 2025-06-11), meaning the $325M round dwarfs the rest of the disclosed values.
Timing and geography also cluster. Rounds are concentrated in late 2024 and mid-2025, with multiple entries landing in November 2024 (e.g., Epic Cleantec $12M on 2024-11-21; Aquaria $100M on 2024-11-20) and a cluster of mid-2025 rounds from June through August 2025 (e.g., Disa $23M on 2025-08-06; Waterly $4M on 2025-08-14). The dataset also shows a heavy classification gap: 12 of 47 rows are “Series Unknown” and 3 of 47 are “undisclosed,” while disclosed amounts range from a low of $30K (Galveston Bay Foundation on 2023-06-21) to the $325M high. The most recent row is Baniql (undisclosed) on 2025-10-17; the oldest shown is Gradiant (Series C) on 2021-11-18.

Frequently asked
Which round is the clear outlier by disclosed size, and how does it sit relative to the rest?
Central States Water Resources’ $325M round on 2024-12-02 is the only disclosed deal in a dramatically higher range than the rest: Aquaria raised $100M on 2024-11-20, while several other large rounds sit far below (e.g., Hycroft Mining $44M on 2025-06-11; Talon Metals Corp $41M on 2025-06-09).
Do the most recent rounds cluster into a narrow window rather than being evenly distributed?
Yes. The list shows multiple late-2024 fundings in close succession (e.g., Aquaria $100M on 2024-11-20 and Epic Cleantec $12M on 2024-11-21) and again in mid-2025 (e.g., Disa $23M on 2025-08-06 and Waterly $4M on 2025-08-14), rather than isolated single-date events.
Are there notable geographic concentrations, or is funding spread across many cities?
Compared with true “one-city dominance,” this list is broadly distributed across states and cities (California appears repeatedly in different places, such as San Francisco for Epic Cleantec on 2024-11-21 and Huntington Beach for AstroForge on 2024-08-21). At the same time, multiple entries reuse the same city name conventions—Reno, Nevada shows up more than once (e.g., NuLegacy Gold $730K on 2024-08-15 and i-80 Gold $24M on 2023-07-18).
What does the stage mix look like when classifications are missing?
A sizable share cannot be staged precisely: 12 of 47 rows are labeled “Series Unknown,” and 3 of 47 are “undisclosed.” Among the most recent dated entries, this matters for comparisons such as Baniql (undisclosed, 2025-10-17) and Terradot (undisclosed, 2025-05-02), which won’t anchor sizing or stage-based benchmarking.
Which smallest disclosed round provides the lower bound for deal size, and where does it fall in context?
Galveston Bay Foundation’s $30K round on 2023-06-21 is the smallest disclosed amount in the visible rows. Even within the same broader period, the gap to mid-range rounds is stark—for example, Global Water Resources raised $3M on 2023-06-09 and i-80 Gold raised $24M on 2023-07-18.
